Answer First
The 6-EVF-100 12V100Ah is a high-capacity valve-regulated lead-acid (VRLA) deep-cycle battery engineered for the heaviest electric mobility applications: 4-wheel electric low-speed vehicles, electric sightseeing buses, heavy-duty cargo tricycles, airport ground support equipment, and large-format e-bike / e-scooter battery banks. Rated at 12V100Ah with a 5-hour discharge rate (C5=100Ah), the 6-EVF-100 sits between the 6-DMF family (32-58Ah) and the 6-FD family (72-75Ah), giving OEMs a mid-to-high capacity option that delivers 100Ah without jumping to the larger, heavier 6-FD-75 footprint.
For OEM procurement managers, battery distributors, and electric vehicle integrators, this guide covers everything you need before issuing a purchase order: what the 6-EVF-100 actually is, the meaning of every character in the model code, the real performance data from CHISEN factory tests and field deployments, how it compares to 6-EVF-80 and 6-EVF-150, what it costs at different MOQs, and how to avoid the five most common sourcing mistakes (wrong C-rate, missing export documentation, counterfeit “100Ah” labels, incorrect charger pairing, and undersized wiring). After reading, if you still have questions about whether the 6-EVF-100 fits your vehicle platform, contact CHISEN directly — our application engineering team responds within 24 hours to qualified buyers with detailed application guidance.
Key Takeaways
1. The 6-EVF-100 12V100Ah is a purpose-built 12V deep-cycle VRLA battery for 4-wheel electric vehicles and high-capacity e-mobility platforms, delivering a verified 350-600 cycle life at 50%-80% depth of discharge (DOD) and operating reliably from -15°C to 50°C. It is the bridge product between the popular 6-EVF-80 (80Ah) and the larger 6-EVF-150 (150Ah), giving OEMs a true 100Ah option in a standardized footprint.
2. Every character in “6-EVF-100” follows Chinese national and industry standards. “6” = 6 cells × 2V = 12V total. “E” = Electric Vehicle (the standard letter for high-power EV motive batteries, distinct from “D” used for lighter e-bike batteries). “V” = Vehicle-class deep cycle. “F” = Valve-regulated (Fa Kong, VRLA). “100” = rated capacity of 100Ah at the 5-hour rate. The 6-EVF family is recognized across the Chinese battery industry as the standard high-capacity EV battery platform.
3. The 5-hour rate (C5) matters — and most competitors lie about it. Many batteries labeled “12V 100Ah” on global B2B platforms are actually rated at the 20-hour rate (C20), meaning real-world usable capacity at the EV-required C5 rate is only 78-85Ah. The CHISEN 6-EVF-100 is genuinely rated C5=100Ah, meaning it actually delivers 100Ah at the discharge rate that electric vehicles demand. This 20-30% real-world advantage is why OEM engineers prefer CHISEN.
4. The 6-EVF-100 builds flexible voltage systems: 4 units in series = 48V (passenger), 6 units = 72V (cargo), 8 units = 96V (heavy-duty). For 4-wheel electric low-speed vehicles (LSVs) and electric sightseeing buses, the standard configuration is 4-6 units in series, depending on motor power and target range. For airport ground support tugs and heavy cargo trikes, 6-8 units in series is more common.
5. Direct-from-factory sourcing eliminates 15-30% trading company markup. Factory pricing on Alibaba ranges from $58 to $85 per unit depending on seller type. Direct CHISEN factory orders with OEM/ODM customization (logo silk-screen, color box, Pantone shell color, custom MSDS) start at MOQ 100 units for samples, 500+ units for production. Trade terms: FOB Ningbo, CIF by sea, or DDP to inland destinations in Africa, Latin America, or Southeast Asia.
Detailed Specifications — CHISEN 6-EVF-100 12V100Ah
The Pain — Why Most “12V 100Ah” Batteries Fail in EV Applications
The 6-EVF-100 is sold into a market plagued by four recurring pain points. If you have already experienced any of these, you already know why the source matters more than the price.
Pain #1 — The 100Ah That Isn’t Really 100Ah
Walk through Alibaba or Made-in-China and search “12V 100Ah VRLA battery”. You will see hundreds of listings claiming 100Ah capacity. The reality: the vast majority of these are rated at the 20-hour rate (C20), meaning the battery delivers 5A for 20 hours to reach 100Ah on the label. But your electric vehicle pulls 20-30A continuously — far above the C20 test current. At that real-world discharge rate, those “100Ah” batteries actually deliver only 75-85Ah.
The math is brutal: if your e-sightseeing bus is rated for 80 km per charge with a true 100Ah battery, the same bus with a C20-rated “100Ah” battery delivers only 60-68 km. That is a 15-20% range reduction, and your customers will blame the vehicle manufacturer — not the battery supplier they never knew was the root cause.
The CHISEN 6-EVF-100 is rated at C5=100Ah, meaning it is verified to deliver 100Ah at a 20A discharge current — exactly the working range for 48V-72V electric vehicles. Real-world testing in CHISEN’s application lab shows the 6-EVF-100 actually delivers 102-104Ah at the C5 rate, providing a small over-capacity margin that protects OEM warranty exposure.
Pain #2 — Cycle Life Claims That Disappear Under Load
A competitor’s spec sheet claims “1200 cycles at 100% DOD” for their 12V 100Ah battery. The fine print, often buried on page 4, says “test conditions: 25°C ambient, 0.2C discharge to 1.75V/cell, IEC 60254 cycle test”. Your e-trike operates at -10°C to 45°C ambient, discharges at 0.5C-1C, and routinely hits 80% DOD in field use.
Under those real-world conditions, that competitor’s “1200 cycles” becomes 250-350 cycles. After 12-18 months of daily use, the battery is at 70% capacity and your fleet operator is buying replacements.
The CHISEN 6-EVF-100 spec is honest: 350 cycles at 80% DOD, 600 cycles at 50% DOD, tested under GB/T 32620.1 and CHISEN internal QC standards at actual operating temperatures. For an e-sightseeing bus operating at 50% DOD average, this translates to 4-5 years of daily service. For a heavy cargo trike at 70% DOD, 2.5-3 years. These numbers are conservative — CHISEN field data from 2022-2025 shows 7-9% better real-world cycle life than spec.
Pain #3 — Missing or Forged Export Documentation
Battery shipments to Africa, Latin America, Southeast Asia, and the Middle East require specific documentation: MSDS (Material Safety Data Sheet), IMDG transport certificate, UN 38.3 test summary, certificate of origin, and often country-specific certificates (SONCAP for Nigeria, PVoC for Kenya, etc.). A surprising number of China-based battery sellers cannot produce valid documentation — they either don’t have it, or they provide generic templates that fail customs inspection.
The result: your 40-foot container gets held at Lagos, Mombasa, or Santos port for 4-8 weeks while you scramble for documentation. Demurrage fees alone can exceed $8,000. In worst cases, the shipment is rejected and returned at your cost.
CHISEN provides complete, batch-specific export documentation with every shipment: real MSDS tied to the actual battery model, current IMDG compliance, UN 38.3 test report from a CNAS-accredited lab, certificate of origin from CCPIT, and pre-shipment quality inspection report. For high-volume African buyers, we pre-register with SONCAP/PVoC certification programs to accelerate clearance.
Pain #4 — The Charger Mismatch That Kills Batteries Early
A common field failure mode: an OEM buys a quality 6-EVF-100 battery but pairs it with a generic 12V 20A charger designed for lower-capacity batteries. The charger pushes 20A into a battery that, at 50% state of charge, can only accept 12-15A safely without overheating. Within 30-60 cycles, the battery shows premature capacity loss because of chronic under-charge followed by over-charge gassing.
The 6-EVF-100 requires a matched charger: output voltage 14.4-14.8V (equalize), 13.5-13.8V (float), current limit 0.15C-0.20C (15-20A), with temperature compensation (-3mV/°C/cell). CHISEN supplies matched chargers as part of OEM kits, and provides free charger selection guidance to qualified buyers.
The Choice — Why CHISEN 6-EVF-100 Over the Alternatives
When you compare the 6-EVF-100 against the four most common alternatives — generic Chinese VRLA, premium Western brand (Trojan, US Battery), cheaper DZF-series upgrade, or down-spec’d EVF — the decision matrix becomes clear.
Comparison Table — 6-EVF-100 vs Alternatives
The conclusion is straightforward: the CHISEN 6-EVF-100 is the right answer for OEM buyers who need verified 100Ah C5-rated capacity at a competitive factory-direct price, with full export documentation and customization support. Generic “100Ah” batteries from trading companies are a gamble; premium Western brands are 2-3× the price without proportional benefit.
The Framework — How to Specify the Right 6-EVF-100 Configuration
Once you decide on the 6-EVF-100, the next decision is configuration. Use this framework to specify the exact battery pack for your vehicle platform.
Step 1 — Determine Voltage System
Step 2 — Calculate Pack Capacity Requirement
For a 72V system with 6-EVF-100: pack nominal capacity = 100Ah, total energy = 72V × 100Ah = 7.2 kWh. Usable energy at 50% DOD = 3.6 kWh, at 80% DOD = 5.76 kWh. Expected range depends on vehicle efficiency: typical e-sightseeing bus = 80-100 km per charge, e-cargo trike = 60-80 km per charge.
If your range requirement exceeds this, consider the 6-EVF-150 (50% more energy per unit) or parallel two 6-EVF-100 packs (with proper battery management).
Step 3 — Match the Charger
Use only temperature-compensated, multi-stage chargers (constant current → constant voltage → float). CHISEN supplies matched chargers with every OEM order at no additional cost for orders ≥100 units.
Step 4 — Plan for Battery Management
For multi-unit packs (especially 6-8 units), install a Battery Management System (BMS) that monitors:
- Individual cell voltage (detect imbalance > 0.2V)
- Pack voltage (over-voltage / under-voltage cutoff)
- Pack temperature (thermal protection)
- State of Charge (SOC, optional but recommended for fleet operators)
- Material Standards: 99.99% purity lead, imported AGM separators, German-engineered safety valves, ABS UL94 V-0 flame-retardant container.
- Process Control: Automated plate casting, computer-controlled acid filling, 72-hour formation cycling, batch-level traceability via serial number.
- Testing Standards: GB/T 32620.1 (Chinese national standard for lead-acid batteries for electric vehicles), IEC 60254 (international lead-acid traction battery standard), CHISEN internal QC exceeds both standards by 15-25% on cycle life and capacity retention.
- Certifications: CE / RoHS / REACH / MSDS / UN 38.3 / ISO 9001:2015 / ISO 14001:2015. SONCAP and PVoC documentation available for African shipments; NOM documentation for Mexico; SABER documentation for Saudi Arabia.
- Capacity Verification: Every batch ships with a factory load test report showing actual measured capacity at C5 rate. Average: 102-104% of rated capacity.
- Sample order (1-10 units): $85-95 per unit
- Small order (100-499 units): $72-80 per unit
- Production order (500-999 units): $65-72 per unit

FAQ — Frequently Asked Questions About CHISEN 6-EVF-100
What vehicles use the 6-EVF-100?
The 6-EVF-100 is designed for medium-to-large electric vehicles: 4-wheel electric low-speed vehicles (LSVs), 8-14 seat electric sightseeing buses, electric cargo trikes with 1-2 ton payload, airport ground support tugs, and large-format e-bike / e-scooter battery banks. For smaller e-bikes, the 6-DZF or 6-DMF series is more appropriate. For larger industrial EVs, consider the 6-FD-72 / 6-FD-75 family.
How long does the 6-EVF-100 last?
Cycle life depends on depth of discharge and operating temperature. At 50% DOD and 25°C ambient, expect 600+ cycles (5-7 years of daily use). At 80% DOD and 35°C ambient, expect 350+ cycles (2.5-3 years). Cold temperatures (-15°C to 0°C) reduce usable capacity by 15-25% but do not cause permanent damage. High temperatures (>40°C sustained) accelerate grid corrosion and reduce total life by 20-30%.
Is the 6-EVF-100 a genuine 100Ah battery?
Yes — rated at the 5-hour rate (C5), meaning it delivers 100Ah at a 20A continuous discharge current. This is the rate that electric vehicles actually operate at. Many competitor “12V 100Ah” batteries are rated at C20 (5A discharge), which inflates the capacity number by 20-30%. CHISEN ships every batch with a factory load test report showing actual measured capacity at C5, which averages 102-104% of rated value.
Can the 6-EVF-100 be shipped internationally?
Yes. CHISEN ships the 6-EVF-100 worldwide with full export documentation: MSDS (Material Safety Data Sheet), IMDG transport certificate, UN 38.3 test summary, certificate of origin, pre-shipment inspection report, and country-specific certifications as required (SONCAP, PVoC, NOM, SABER).
