What Are the Key Specifications of 340Ah LiFePO4 Batteries?
Each 3.2V cell delivers 340Ah capacity, enabling 32-cell configurations for 12V/24V systems. Key specs include 10000 cycles at 80% depth of discharge (DoD), -20°C to 60°C operating range, and built-in BMS for overcharge/over-discharge protection. A-grade cells guarantee minimal capacity degradation (<3% annually), ensuring reliable performance for solar storage or EV conversions.
| Parameter | Value |
|---|---|
| Nominal Voltage | 3.2V per cell |
| Cycle Life | 10,000 cycles @ 80% DoD |
| Energy Density | 125 Wh/kg |
| Charging Temperature | 0°C to 45°C |
The wide operating temperature range allows these batteries to function efficiently in extreme environments, from desert solar farms to arctic research stations. Advanced electrode design minimizes internal resistance, enabling 2C continuous discharge rates without voltage drops. For solar installations, the 98% round-trip efficiency ensures minimal energy loss during daily charge/discharge cycles. Users can monitor cell health via Bluetooth-enabled BMS modules that track voltage differentials and temperature gradients in real time.
How Do LiFePO4 Batteries Outperform Lead-Acid Alternatives?
LiFePO4 batteries provide 4x longer lifespan (10,000 vs. 2,500 cycles), 95% efficiency (vs. 80% for lead-acid), and 50% lighter weight. They maintain stable voltage under heavy loads, unlike lead-acid’s voltage sag. With no acid leaks or gas emissions, they’re safer for enclosed spaces like RVs.

Which Applications Benefit Most from 340Ah LiFePO4 Packs?
DIY 12V/24V solar systems, RV power upgrades, marine trolling motors, and electric vehicle conversions gain the most. Their modular design allows scalable storage (10.8kWh per 32-cell pack). Solar setups achieve 98% round-trip efficiency, while EVs leverage fast charging (1C rate) and regenerative braking compatibility.
How to Install 32pcs LiFePO4 Cells in a 12V/24V System?
For 12V: Connect 4 cells in series (4S). For 24V: 8S configuration. Use busbars with 200A fuses and a centralized BMS. Ensure cells are balanced within 0.05V tolerance. Mount in vented enclosures, maintaining 2mm spacing between cells. Torque terminals to 4-6Nm. Test system voltage (13.2V for 12V) before connecting inverters.
When configuring large battery banks, use copper busbars with anti-oxidation coating to prevent resistance buildup. Install a Class T fuse on the main positive terminal for overcurrent protection. For RV installations, secure cells with vibration-dampening mounts to withstand road shocks. Balance cells every 6 months using a passive balancing charger to maintain capacity uniformity. Always disconnect solar panels before servicing battery connections to avoid arc flashes.
What Safety Features Protect LiFePO4 Battery Systems?
Built-in BMS prevents overvoltage (>3.65V/cell), undervoltage (<2.5V/cell), and short circuits. A-grade cells include flame-retardant separators and aluminum alloy casings. Thermal runaway thresholds exceed 200°C, unlike NMC batteries. Install temperature sensors and pressure relief vents for added safety in high-demand applications.
Can 340Ah Batteries Integrate With Solar Inverters?
Yes. Use MPPT charge controllers (48V max input) for solar integration. Compatible with Victron MultiPlus, Renogy Rover, and Growatt inverters. Set absorption voltage to 14.4V (12V system) and float voltage to 13.6V. Ensure inverter low-voltage cutoff matches BMS thresholds (2.8V/cell). Parallel multiple packs for 48V systems without voltage imbalance.
What Environmental Advantages Do LiFePO4 Batteries Offer?
LiFePO4 cells contain non-toxic iron phosphate, avoiding cobalt’s ethical concerns. They’re 99% recyclable, with 70% lower carbon footprint than lead-acid. Solar systems using these batteries reduce grid reliance, cutting CO2 by 1.2 tons annually per 10kWh daily usage.
