The Limetime 12V 230Ah LiFePO4 Battery with Low-Temp Protection is designed for reliable performance in sub-zero environments. Its lithium iron phosphate chemistry ensures 3,000+ cycles, 30% lighter weight than lead-acid alternatives, and built-in safeguards against freezing damage. Ideal for RVs, marine use, and off-grid solar systems requiring stable power below 0°C (-20°C discharge capability).

What Are the Key Specifications of the 12V 230Ah Plus Model?
This battery delivers 230Ah (2.94kWh) with 100% depth of discharge capability. Key specs include: 200A continuous discharge current, IP65 waterproof rating, ±0.05V cell balancing accuracy, and 10-year design lifespan. Its compact dimensions (522x240x218mm) and 25kg weight make it 40% smaller than equivalent lead-acid systems while providing 3x faster charging via 50A max solar input.
| Parameter | Specification |
|---|---|
| Energy Capacity | 2.94 kWh |
| Peak Discharge | 400A (5 seconds) |
| Charge Temperature | -20°C to 55°C |
| Terminal Type | M8 Stainless Steel |
The advanced cell configuration uses prismatic cells with laser-welded terminals, reducing internal resistance by 18% compared to standard models. Its modular design allows for series connections up to 48V systems without voltage droop. The built-in Bluetooth module enables real-time monitoring of state-of-charge (SOC) and cell voltages through dedicated mobile apps, particularly useful for remote installations in harsh climates.
How Does It Compare to Traditional AGM Batteries in Cold Weather?
At -20°C, AGM batteries lose 60% capacity vs the Limetime’s 20% loss. Charging efficiency differs dramatically: AGM requires 14.4-14.8V absorption charging in cold, while the LiFePO4 BMS auto-adjusts voltage parameters. Cycle life comparison shows 300 cycles for AGM vs 3,000+ for Limetime in sub-zero conditions, with 92% round-trip efficiency versus AGM’s 75-80%.
| Feature | Limetime LiFePO4 | AGM Battery |
|---|---|---|
| -30°C Capacity | 72% | 38% |
| Recharge Cycles | 3,000+ | 300-500 |
| Weight (kg) | 25 | 64 |
Field tests demonstrate the Limetime maintains 85% charge acceptance at -15°C compared to AGM’s 35%, reducing solar array requirements in winter. Its sealed construction prevents electrolyte freezing issues common in lead-acid batteries below -30°C. The thermal mass of lithium iron phosphate cells also enables faster recovery from deep discharge states in cold conditions.
“The Limetime’s -40°C discharge capability breaks industry norms. Most LiFePO4 batteries derate below 0°C, but their nano-porous electrode design maintains ionic conductivity at extreme temperatures. For Arctic solar projects, we’ve seen 98% winter availability compared to 67% with heated lead-acid systems.”

FAQs
- Can I charge this battery while it’s below freezing?
- Yes, but only through the battery’s internal heating system activated at -20°C. External charging below this temperature is blocked by the BMS until cells warm above -15°C via 40W built-in heaters.
- How long does it last in -30°C conditions?
- At -30°C with 100W continuous load: 230Ah × 12V = 2,760Wh. Accounting for 25% capacity loss and 90% inverter efficiency: (2,760 × 0.75) / 100W = 20.7 hours runtime. Actual field tests show 18-22 hours depending on load cycling.
- Does it require special solar charge controllers?
- Compatible with standard LiFePO4-ready controllers (Victron, Outback). For optimal cold performance, use controllers with temperature-compensated charging like the Victron SmartSolar 100/50, which syncs with the battery’s BMS via Bluetooth for real-time voltage adjustments.
