3S 25A Li-Ion 18650 BMS PCM Battery Protection Board Bms Pcm With
Balance For Li-Ion Lipo Battery Cell Pack
Product Description:
3 Series 18650 battery
11.1V (Li-ion 18650 or li-ion battery rated voltage)12. 6V (Li-ion
battery full charge voltage)10.8V ( Lipo battery pack rated
voltage)The lithium battery protection board is not included the
welding tabs
BMS activate method : Use 12. 6V Li-ion charger to charge it.
NOTE:
1) This board is not suit high power electronic tools, if use for
screwdrier anddrill,electric bike series make, fishing machine and
1W LED, please don't buythis.
2)Above 3A device, means the battry discharge rate is more than 3C.
1C rated battery.2000mah equals 2ah*1=2A max working current.
3C rated battery means 2ahx3=6A Max working current.
Balancer is just a Auxiliary function, The balancing means when the
batterycharging.each series battery need with the same voltage.when
ONE cell voltageget 4.2V ,the other cells not, the first cell
voltage will discharge to wait theother cells rising to the same
level.
Note:battery internal resistance differences within 5 milliohm, voltage
within 0.03 Yvoltage. capacity vary within 50 ma
Features:
1) high-accuracy voltage detection circuit:
2) terminal of the charger using high voltage device;
3) Built-in threestage over-current detection circuit (over-current
1.over-current 2 or load short circuit);
4) MOS transistor can control the battery charge and discharge:
5) low standby current consumption.
