Ebike Scooter EV Energy Storage Lithium Battery BMS Board 4S 12V 250A 3.2V LiFePO4 Battery BMS
LiFePO4 Battery BMS Description:
The lithium iron phosphate battery is a lithium-ion battery using lithium iron phosphate (LiFePO4) as the positive electrode material and carbon as the negative electrode material.
LiFePO4 batteries have the advantages of high working voltage, high energy density, long cycle life, good safety performance, low self-discharge rate and no memory effect.
BMS FUNCTION:
★ Overcharge protection: prevent overcharge and affect battery life
★ Short circuit protection: automatic protection during abnormal short circuit to prevent damage to the protection board and
battery
★ Over-discharge protection: prevent the battery from being dead and affect the battery life
★ Over-current protection: prevent current from exceeding the battery's tolerance, causing battery damage
★ Drop-out protection: prevent the cable from being dropped or the contact is poor, and the battery loses protection
★ Over-temperature protection: prevent the battery temperature from becoming too high, causing spontaneous combustion or damag

LiFePO4 Battery BMS FAQ:
Q:1. OEM&ODM are available?
A: Sure, OEM&ODM are welcome and the Logo can be customized too.
Q:2. The relationship between Battery capacity and BMS current?
A: There is no direct relationship between Battery capacity and BMS current, big capacity doesn`t mean a big battery, but relies on
continue current, that is to say, if your engine is powerful, you should choose a high current of BMS, it does not rely on battery capacity.
Q:3. Whether my BMS damaged?
A: if you want to judge if the BMS is damaged, please take the following steps, to test if each cell voltage is the same as with the voltmeter. if the cell voltage difference is over 1.0V, the fault is displayed that it cannot run far, no power supply at the start range, short charge time, all these issues are almost caused by battery cells, if BMS damaged is displayed as no charge, no discharge, no discharge while the battery has voltage.
