14.8V 16.8V 30A 4S Lithium Li-ion LiPo Polymer Battery BMS PCB System Balance บอร์ดชาร์ท ควบคุม แบตเตอรี่
Specification:
- Condition: 100% brand new
- Product Size: About 60 x 46 x 3.5mm
- Charging Voltage: 16.8V - 18.1V
- Continuous Charge Current (upper limit): 20A
- Continuous Discharge Current (upper limit): 40A (if the cooling environment is not good, please reduce the load current use)
HOW TO USE
1. Choose the right Li Battery. we must know how many C of Li Battery we want to use. If you want to driver the large current fixture with small C battery that it does not work or work well
2. Test the voltage of every battery, to make sure that the voltage does not below the Over-discharge protection voltage or over the overshoot recover voltage. Normally choose similar one for one pcB
3. Connect the PCB with battery correctly
4. Connect the right load.
ATTENTION
1. After connecting the wire, it needs to be charged before it has output
2. In series 4 batteries, please ensure that the voltage of each battery is the same. If it is different, please charge each battery separately and then use it in series. In the discharge test, the rapidly decreasing of voltage battery is the poor battery
3. Don't mix good batteries with bad batteries! The more similar the battery capacity or internal resistance, the better!
Connection description:
P+ P- is the abbreviation of PACK+ PACK-, that is, the output of positive and negative poles;
B+ B- is the abbreviation of BATTERY. which is the positive and negative pole of the battery.
