6-EVF-150 12V 150Ah High-Capacity Tubular Gel Battery: Industrial & EV Procurement Guide (2026)
For industrial buyers sourcing large-format deep-cycle batteries — solar microgrid integrators, electric vehicle propulsion packagers, floor cleaning machine OEMs, and heavy-duty traction applications — the 6-EVF-150 is the capacity step where CHISEN’s tubular gel technology delivers the strongest return on investment. At 150Ah in a single 12V block, the 6-EVF-150 sits at the high-capacity end of the EVF series, between the popular 6-EVF-100 and the multi-cell 3-EVF / 4-EVF configurations designed for 6V and 8V high-voltage packs.
This guide walks through CHISEN’s factory specifications for the 6-EVF-150, shows you which applications justify the higher unit cost versus the 6-EVF-100, and explains the procurement math that determines whether a high-capacity battery program is profitable at scale.

Compared to the 6-EVF-100 (31.5 kg, 100Ah), the 6-EVF-150 delivers 50% more capacity at 54% more weight. The energy density is slightly higher in the 150Ah variant due to the optimized plate stacking — CHISEN’s engineers tuned the plate count and separator compression for the 150Ah cell to maximize Wh/kg while preserving the long cycle life that the EVF series is known for.
When to Choose 6-EVF-150 Over 6-EVF-100
The decision between the 6-EVF-100 and the 6-EVF-150 comes down to three application factors: capacity requirement, cycle life requirement, and total cost of ownership. Below is a side-by-side comparison:
| Application Factor | 6-EVF-100 | 6-EVF-150 |
|---|---|---|
| Daily energy need (kWh) | 1.0–1.4 | 1.4–2.0 |
| Required cycle life at 80% DoD | 600 cycles | 600 cycles |
| Weight-sensitive application | ✅ 31.5 kg | ⚠️ 48.5 kg |
| Vehicle-mounted application | ✅ | ✅ |
| Solar microgrid (residential) | ✅ | ✅ (oversized) |
| Solar microgrid (commercial) | ⚠️ (undersized) | ✅ |
| EV propulsion (small vehicle) | ✅ | ✅ |
| EV propulsion (utility vehicle) | ⚠️ (undersized) | ✅ |
| Floor scrubber / sweeper | ✅ | ✅ (larger models) |
| Telecom BTS cabinet | ✅ | ⚠️ (oversized) |
| Marine house bank | ✅ | ✅ |
| Single-battery replacement cost | $143–$178 | $220–$260 |
For solar microgrid applications in the commercial segment (small business, rural clinic, school, or small commercial facility), the 6-EVF-150 is the correct size because the daily energy demand is typically 1.5–2.0 kWh, which is beyond the single-day capacity of a 6-EVF-100. Two 6-EVF-150 batteries in parallel can deliver 3.0 kWh per day, which covers most small commercial solar installations.
Application Matrix for 6-EVF-150
| Application | Recommended Configuration | Daily Cycles |
|---|---|---|
| Commercial solar microgrid | 2 × 6-EVF-150 (parallel) | 1 cycle |
| Utility electric vehicle (golf cart, AGV) | 4 × 6-EVF-150 (series, 48V) | 1 cycle |
| Heavy-duty floor scrubber | 4 × 6-EVF-150 (series, 48V) | 1–2 cycles |
| Telecom BTS (high-power site) | 1 × 6-EVF-150 | Float duty |
| Marine house bank (mid-size yacht) | 2 × 6-EVF-150 (parallel) | 1 cycle |
| RV house bank | 2 × 6-EVF-150 (parallel) | 1 cycle |
| Off-grid cabin | 4 × 6-EVF-150 (series-parallel, 24V 300Ah) | 1 cycle |
For utility electric vehicles like the Club Car Carryall 500 or Polaris Ranger EV, the standard 48V battery bay is configured for four 12V batteries in series. Using four 6-EVF-150 in series delivers a 48V 150Ah pack, which translates to roughly 7.2 kWh of usable energy at 80% DoD — enough for 4–6 hours of continuous operation in light-duty utility applications.
Cycle Life and Total Cost of Ownership
The 6-EVF-150 is rated for ≥ 600 cycles at 80% DoD, which means a daily discharge of 80% delivers approximately 600 days of service — about 1.6 years in heavy solar duty. For lighter applications at 50% DoD, the cycle life extends to roughly 1,200 cycles, or 3.3 years of service.
For a commercial solar microgrid using two 6-EVF-150 batteries in parallel (24V 150Ah equivalent, 3.0 kWh per day), the total cost of ownership over 5 years looks like this:
| Cost Component | Calculation | 5-Year Cost |
|---|---|---|
| Initial battery purchase | 2 × $245 (1,000-unit tier) | $490 |
| Battery replacement (year 1.6 + year 3.3) | 4 × $245 | $980 |
| Battery replacement (year 5) | 2 × $245 (estimated) | $490 |
| Total battery cost over 5 years | — | $1,960 |
Compared to a generic 12V 150Ah AGM battery that delivers 200–300 cycles at 80% DoD, the 6-EVF-150 lasts roughly 2–3x longer, which means 2–3 fewer battery replacements over the 5-year period. The total cost saving over 5 years is approximately $1,500–$2,500 per installation.
Drop-In Replacement Compatibility
The 6-EVF-150 shares its 170 mm width and 240 mm height with the 6-EVF-100, but the 483 mm length is longer. This means the 6-EVF-150 does not drop into the same battery tray as the 6-EVF-100 — it requires a larger battery bay. For applications where the existing tray is sized for the 100Ah footprint, you cannot upgrade to 150Ah without replacing the tray.
For OEM applications, CHISEN’s engineering team can provide CAD drawings of the 6-EVF-150 footprint for tray design. Lead time for a custom tray is typically 30 days. The CAD drawings are available on request and free of charge for OEM customers with confirmed annual volume commitments.
Lead Time, MOQ, and Pricing
Standard 6-EVF-150 production orders run on a 25-day lead time for orders under 500 units and 35–40 days for full container loads. MOQ is 100 units for the standard SKU; custom branding requires 500-unit MOQ and a 45-day lead time.

|---|---|
| 100 units | $265 |
| 500 units | $245 |
| 1,000 units | $228 |
| 5,000 units | $212 |
A 20GP container holds approximately 600 units; a 40HQ holds approximately 1,400 units. DDP terms are available for the United States, Germany, and the UAE.
Frequently Asked Questions
What is the difference between 6-EVF-150 and 6-EVF-150B?
The 6-EVF-150B has a slightly heavier weight (52.5 kg) and a higher cycle life rating (≥ 700 cycles at 80% DoD). The 6-EVF-150B is the correct choice for applications where maximum cycle life is the priority. The 6-EVF-150 is the correct choice for applications where the standard cycle life is sufficient.
Can I use the 6-EVF-150 in parallel with the 6-EVF-100?
Technically yes, but not recommended. Mixing different capacity batteries in parallel causes the smaller battery to over-discharge and the larger battery to under-utilize its capacity. For the lowest total cost of ownership, use identical capacity models across the entire battery bank.
What is the maximum string length for 6-EVF-150 in series?
Up to 4 batteries in series (48V system) is standard. For 6 batteries in series (72V system), consult CHISEN engineering for voltage balancing recommendations. Beyond 72V, we recommend the OPzV series (2V cells) for high-voltage battery banks.
Can the 6-EVF-150 be used in a 24V system?
Yes. Two 6-EVF-150 batteries in series deliver 24V 150Ah. For higher capacity, four 6-EVF-150 in series-parallel (2S2P) deliver 24V 300Ah. For 48V systems, four 6-EVF-150 in series (4S1P) deliver 48V 150Ah, or eight 6-EVF-150 in series-parallel (4S2P) deliver 48V 300Ah.
