3S 11.1V 10A 18650 Lithium Battery Overcharge And Over-current Protection board

3S 10A 12V 18650 Lithium Battery Charger Board Protection Module

The 3S 10A 12V 18650 Lithium Battery Charger Board Protection Module is designed for a series combination of three 18650 batteries or polymer lithium batteries. It can charge lithium batteries with a rated voltage of 10.8V for polymer batteries, 11.1V for 18650 or 3.7V batteries, and 12.6V. It can also discharge up to 10A (the maximum current limit for discharge). The module has built-in protection against over-charging, over-discharging, over-current, and short circuit.

Formula expansion :

1C battery expansion, 2000 capacity is equal to 2AH x 1 = 2A upper limit of current.
3C battery expansion, 2000 capacity equal to 2AH x 3 = 6A upper operating current.

If the battery gets heated, does not apply that battery, such a situation cannot be long-term use, the battery will soon be damaged.

Notes :

1: strictly according to the drawing wiring 0 V (B), 3.7 V (B1), 7.4 V (B2), 11.1 V (B +), not intentionally short circuit!
2: Once you have charged the first line, it will have output.
3: When connecting three battery groups, please make sure that the voltage of each battery group, if not the same, fill each battery separately and then use it in series. discharge test, the fastest battery voltage drop, which group is low battery. (2 good battery + a use effect = 3 low battery low battery use effect).

Warning:

This protection board is not compatible with lithium iron phosphate batteries, xenon lamps, cordless drill batteries, electric fishing batteries, electric bike batteries, children’s car batteries, 775 (4A) motors, or 1 W fish eye LED lights. Customers should pay attention to the specifications before buying! The following products can use this protection board as a power source: Rechargeable massager, LED emergency light, 12 V electronic device, solar street light battery, backup monitor power, and other similar products.
