Professional introduction of 5KWH 100AH 51.2V Lifepo4 Battery (51.2V 100Ah)
I. Core performance advantages
Extremely long cycle life

A-grade lithium iron phosphate battery, cycle life ≥ 6000 times (80% DOD), which is 12 times that of lead-acid battery (500 times) and 3 times that of ternary lithium battery (2000 times).

Service life is more than 10 years, annual capacity decay <3%, and long-term use cost is lower.

High safety performance

Excellent thermal stability (decomposition temperature > 500℃), no fire or explosion, FCC/CE certified.

Built-in 5A active equalizer, real-time adjustment of battery cell voltage difference (≤20mV) to avoid overcharge/over-discharge risks.

Efficient energy utilization

Charge and discharge efficiency ≥ 98% (lead-acid battery is only 80-85%), support 2C fast charge (100A charging current).

80% deep discharge (DOD) does not affect the lifespan, and the lead-acid battery needs to retain 50% of its power.

3.This 5KWH 100AH 51.2V Lifepo4 Battery Built-in 5A active balancing technology
Working principle:

Real-time monitoring of each cell voltage, transfer of high-voltage cell energy to low-voltage cell through DC-DC conversion, balancing current up to 5A (passive balancing is only 50-100mA).

Core value:

Extend the overall life of the battery pack by more than 30%.

Avoid the "barrel effect" and increase the available capacity (the actual available capacity of a 100Ah battery is > 98Ah).
