DGZZI 2PCS 3S 12V 18650 10A BMS Charger Module Li-ion Lithium Battery Protection Board Circuit Board 10.8V 11.1V 12.6V
DGZZI 2PCS 3S 12V 18650 10A BMS Charger Module Li-ion Lithium Battery Protection Board Circuit Board 10.8V 11.1V 12.6V
Description
The protection board can not be used for lithium iron phosphate battery, hernia lamp, hand drill battery pack, electric fish battery pack, electric bicycle battery pack, children's car battery, 775 (4A) motor, 1W fish eye LED light, Please pay attention to the combination of the purchase of customers! The Described in the power range for the following products: Massager battery pack, LED light standby power supply, 12V electronic products, solar street lamp battery pack, monitor backup power supply, and other products. Note: 3A current discharge products above, the battery discharge rate to 3C or more. Magnification calculation formula: 1C magnification of the battery, 2000 capacity is equal to 2AH 1 = 2A upper limit current. 3C magnification battery, 2000 capacity equal to 2AH 3 = 6A upper working current. When in use, if the battery heats, this situation can not be long-term use, the battery will soon be damaged. Note 1: strictly according to Figure wiring 0V (B -), 3.7V (B1), 7.4V (B2), 11.1V (B +), do not deliberately short circuit! Note 2: after the need to charge the first line, will have output. Note 3: When connecting three groups of batteries, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. Discharge test, the voltage drop is fast that group of batteries is poor battery.
Features:
- 3 string (for 3 18650 batteries or polymer lithium battery series combination), 10.8V (rated voltage for polymer battery)
- 11.1V (18650 or 3.7V lithium battery rated voltage), 12.6V (lithium battery is fully charged after the voltage)
- Discharge 10A (refer to the upper limit discharge current limit)
- Never mix a good battery with a bad one!The closer the capacity/internal resistance of the three batteries, the better! (2 good battery + a poor battery use effect = 3 poor battery use effect)
- Short circuit protection, Overcharge protection.
