JBD-AP20S004
JBD-AP20S004 is specially designed for 13 ~ 20 series battery packs of power batteries, electric bicycles, motorcycles and other products; it can be applied to lithium batteries with different chemical properties, such as lithium ion, lithium polymer, lithium iron phosphate, etc. The protection board has strong load carrying capacity and the maximum continuous discharge current can reach 200A.
● 13-20 cell series protection, and automatically recognize the number of battery strings
● The car gauge level simulates the front chip, the voltage acquisition precision is high;more secure and reliable.
● Various protection functions for charging and discharging
● Power switch for relay, high voltage, more reliable.
● Accurate SOC calculation with automatic SOC learning function
● Bluetooth communication
● Optional RS485 communication function can read all battery data in real time and upgrade online.
● Optional CAN communication function
● Reserve switch control protection panel output.There is a discharge switch to have a pre-charge function to prevent lighting
● When the standing time reaches the set value (page switching time for parameter setting), the machine will automatically shut down and sleep to reduce standby power consumption.
● Support series connection, but the total number of series after series connection is less than or equal to 32 series
● Parallel use of battery packs is not supported (battery packs are directly connected in parallel, and there is a problem of
large current discharge of high-voltage battery packs to low-voltage battery packs)

FAQ
1. What type of charger should I choose?
Lithium battery must choose specific charger, do not use Charger for Leadacid battery, for leadacid charger may have MOS with high pressure breakdown protection, which will not protect of BMS over charge. Life Po4 battery charger voltage=battery string No.X3.6V, while Li-ion battery charger voltage=Battery string No.X4.2V.
2.The relationship between Battery capacity and BMS current?
There is no direct relationship between Battery capacity and BMS current, big capacity doesn`t mean a big battery, but rely on continue current, that is to say if your engine is powerful, your should choose high current of BMS, it is not relied on battery capacity.
3.Whether my BMS damaged?
If you want to judge if the BMS is damaged, please take the folowing 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 displyed as no charge, no discharge, no discharge while the battery has voltage.
