For example, 20S of 64V100A protection board, the same port means that your negative charge and negative discharge is connected to the same point of the protection board (P-), charge and discharge negative share a common interface, so his charge current and discharge current are the same as 100A. while the split port, it is just the opposite, the negative charge (C-) and the negative discharge is separated from the negative (P-), connected to a different point on the protection board So the charging and discharging current will be different, discharging 100A, charging 100A.

The size of the battery capacity and the size of the current with the BMS does not have a direct relationship, large capacity is not a large battery, mainly to see the continuous current, that is to say, the larger the current limitation of your controller, the larger the selected BMS continuous current should be, with your battery capacity does not have a direct relationship.

Carp batteries must be charged with a special charger for carp batteries, do not use a lead-acid battery charger, charging with a lead-acid charger may be high-voltage breakdown of the protection board MOS tubes, resulting in overcharging of the BMS is not protected. The voltage of the charger for ferrous batteries = 3.65V; charger for ternary batteries = 4.25V * number of battery strings victron inverter 5000w,victron solar inverter,growatt inverter 5kw,JK Inverter BMS,bms 13s.

Yep! it is designed for energy storage use.

Please tell us following required details and we will advice for you: Battery material & Battery series & Capacity & working current & Application (For example: LiFePO4 BMS, 13 series, charge 40A, discharge 40A, application for e-bike 1800W.)

Please look your battery body, if the normal voltage of your battery shows 3.2V, the battery is LiFePo4. If the normal voltage of your battery shows 3.6V or 3.7V, the battery is Li-ion or Li-polymer battery.

If you want to judge if the BMS is damaged, please take the following steps, to test if each cell voltage is the same with
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.
