This is an equalizer, it could balance the voltage difference between battery series to make the batteries more durable, and the battery life would be longer,
It's not BMS, so it does not have the over-voltage, over-current and over discharge protection, but it can work with BMS together,
It's suitable for Li-ion and LiFePo4 batteries, could be used with any capacity of batteries,
Due to the balance current is fixed, so the balance time for large capacity of battery is slow, and for small capacity battery is fast
Suitable battery types:Li ion/LiFePO4/LTO
Single cell voltage range: Li ion / LiFePO4 version:2.7-4.2V
LTO version:1.8-4.2V
Voltage equilization accuracy: 5mV(Typical value)
Equalization method: The patented balance architecture fit capacitor mode, the entire battery group at the same time to participate in the active balance of energy transfer
Balancing current: Voltage difference is 0.08V, balance current is 1A, the voltage difference is directly proportional to the balance current, the maximum allowable working current is 6.0A
Sleep voltage for undervoltage protection: Li ion / LiFePO4: below2.7V
LTO:below1.8V
Working temperature: -10°～60°
Whether an external power supply is required: No external power supply is needed, and the whole group is balanced by internal energy transfer of the battery
Technical parameters
Operating voltage 1.8V-4.5V, suitable for li-ion, LiFePo4, lithium titanate.
Working principle: the balanced work will be started when the balanced board is connected to the battery. The original ultra-low internal resistance MOS and 2OZ copper thick PCB are adopted, And the balanced current is 0-5.5a, the more balanced battery, the smaller balanced current.
The static current is around 12 mA. It is recommended that the battery capacity should be in the range of 60-300AH!
With undervoltage dormancy protection, if the voltage is less than 1.8V, it will automatically stop into the dormancy state, standby power consumption is less than 0.1 mA.
