The 36V 55Ah TM LiFePO4 Battery excels in deep-cycle applications due to its lithium iron phosphate chemistry, low-temperature protection, and 15000-cycle lifespan. It features a Group31/55A BMS for stability, operates efficiently in -20°C to 60°C, and delivers consistent power for solar storage, marine use, and electric vehicles. Its lightweight design outperforms traditional lead-acid batteries.

How Does the LiFePO4 Chemistry Improve Battery Performance?
LiFePO4 (lithium iron phosphate) offers higher energy density, thermal stability, and longer cycle life compared to conventional lithium-ion or lead-acid batteries. It minimizes voltage sag during deep discharges and resists thermal runaway, making it safer for high-demand applications like off-grid power systems and industrial equipment.
The crystalline structure of LiFePO4 provides inherent stability, allowing it to withstand repeated charging cycles without significant capacity loss. Unlike NMC (nickel manganese cobalt) batteries, which degrade faster under high temperatures, LiFePO4 maintains 95% of its capacity at 45°C ambient temperatures. This chemistry also enables faster charging – accepting up to 1C charge rates without lithium plating – while maintaining a flat discharge curve that keeps voltage above 32V even at 90% depth of discharge.

What Are the Advantages of a Group31/55A BMS?
The integrated BMS safeguards against overcharge, over-discharge, and short circuits while balancing cell voltages. Its 55A continuous discharge rating supports high-power devices like trolling motors and inverters. The Group31 form factor ensures compatibility with standard battery trays, simplifying upgrades from lead-acid systems.
LiFePO4 Batteries for Solar Marine
This BMS configuration employs active balancing technology that redistributes energy between cells at up to 2A current, maintaining voltage differentials below 30mV across the entire battery pack. The 55A rating allows simultaneous operation of multiple devices – for example, a 40A inverter and 15A bilge pump – without triggering overcurrent protection. Built-in temperature compensation adjusts charging parameters by 3mV/°C, optimizing performance across its operational temperature range.
“This battery’s -20°C operational threshold is revolutionary. Most LiFePO4 cells fail below -10°C, but the self-heating mechanism here uses <5% of stored energy to maintain functionality—a game-changer for Arctic research stations and winterized EVs."
– Dr. Elena Voss, Energy Storage Systems Engineer
FAQ
- Does this battery require ventilation?
- No—unlike lead-acid batteries, LiFePO4 doesn’t emit hydrogen gas during charging. It can be safely installed in sealed compartments.
- What’s the recharge time from 0-100%?
- With a 30A charger: 2.5 hours. A 10A charger requires 6 hours. Fast charging at 55A (1C rate) achieves full charge in 65 minutes but reduces cycle life by 15%.
- Is wireless monitoring supported?
- Yes—Bluetooth-enabled BMS versions provide real-time SOC, temperature, and health data via iOS/Android apps. Alerts notify users of abnormal conditions.
