It provides stronger output in the same size and weight, supporting long-range EV driving, multi-day home backup, and industrial high-power supply.
✅LiFePO4 Chemistry for Military-Grade Safety: No Fire, No Explosion
With stable lithium iron phosphate material, it passes strict safety tests including overcharge, over-discharge, short circuit, heating, crushing and temperature cycling. It offers excellent thermal stability and is much safer than conventional lithium batteries, ideal for vehicle, home and energy storage use.
✅4000+ Long Cycles & 10-Year Calendar Life for Lower Total Cost
It reaches over 4000 cycles at room temperature (80% capacity retention) and up to 10 years of calendar life at 25℃ & 50%SOC. Much longer than standard lithium cells, it greatly reduces replacement frequency and long-term cost.
✅Wide Temperature Range: -30℃~65℃, Stable in Extreme Weather
Discharge from -30℃ to 65℃ and charge from 0℃ to 60℃. High capacity retention at low temperature (≥80% at -20℃, ≥85% at 0℃) and stable performance at high temperature. Works reliably in cold northern winters and hot southern summers.
✅Ultra-Low Internal Resistance for Fast Charge & High-Power Discharge
ACR 0.1~0.3mΩ and DCR ≤0.5mΩ. Supports 1C fast charge and step charging, tolerates high-rate pulse discharge and regeneration. High efficiency, low heat, fast power response for vehicle acceleration and ESS peak power demand.
✅Original Grade A with High Consistency, Easy to Assemble with BMS
Prismatic design with precise dimensions. Excellent uniformity in voltage, resistance and capacity. Supports series/parallel assembly and works with most BMS systems. Widely used in EVs, home storage, solar plants, RVs, marine and telecom base stations.
✅International Certifications & Eco-Friendly, Global Shippable
Complies with GB 38031, IEC62619, RoHS and other standards. Free of hazardous substances. Certified UN38.3 for safe sea, land and air transport, supporting global sales and projects.

FAQ
Q1: Can 340Ah 3.2V be connected in series/parallel? How many strings?
A: Yes. This cell has excellent consistency for series/parallel assembly. Common systems:
12V/24V/48V/96V home storage
72V/96V/120V EV / forklift packs
Just use a proper BMS for balancing, temperature control and safety.
Q2: Is insulation necessary during installation? How?
A: Mandatory.
Insulate terminals, busbars, wires with heat shrink, epoxy plate
Cover cell sides with insulation paper
Use insulated tools to prevent short circuit
Q3: Can it work in cold winter? How about capacity at -20℃ / -30℃?
A: Much better than ordinary Li-ion batteries.
≥85% capacity at 0℃
≥80% capacity at -20℃
≥70% capacity at -30℃ (discharge only)
Stable even in cold areas, no “low-temperature dead” issue.
Q4: Does it support fast charge? How to charge safely for long life?
A: Supports regular charge + step fast charge, max 1C.
Suggestions:
Daily: 0.3C–0.5C slow charge (longest life)
Emergency: 1C step fast charge (safe)
Do NOT overcharge: max charge voltage 3.65V, best temp 10–35℃.
Q5: Really 4000 cycles? How many years can it last?
A: ≥4000 cycles at 25℃ 100% DOD (80% capacity remaining).
For daily home storage use:
4000 cycles ≈ over 10 years of service.
With 10-year calendar life, it’s a long-life LFP cell for EV & ESS.
Q6: Is it safe? Will it catch fire or explode?
A: LiFePO4 is intrinsically safe. It passes:
overcharge, over-discharge, short circuit, heating, crushing, temperature cycle.
No fire, no explosion in these tests. Much safer than ternary Li-ion.
Q7: How to store when not in use for a long time?
A: Recommended storage:
Environment: cool & dry, ≤35℃, humidity <85%
SOC: keep 30%~50%
Cycle: charge/discharge every 3 months
Do NOT store at 100% or 0% SOC.
Q8: Do I need pressure when assembling a battery pack?
A: Yes, constrained pressure improves cycle life.
Recommended: 150±50kgf, use insulated steel plates, uniform compression, no looseness.
