This is the 12V variant of the 3S 10A 12V 18650 Lithium Battery Charger Board Protection Module in Battery Protection Board. Available at ₹51.45 (₹43.60 + GST) with free shipping across India.
Description:
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
- 12.6V maximum
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: 2000mAh capacity equals 2Ah × 1 = 2A upper limit of current
- 3C battery expansion: 2000mAh capacity equals 2Ah × 3 = 6A upper operating current
Note: If the battery gets heated, do not use it, as long-term use in this situation will damage the battery.
Notes:
- Strictly follow the drawing wiring: 0 V (B), 3.7 V (B1), 7.4 V (B2), 11.1 V (B+). Do not intentionally short circuit!
- Once the first line is charged, it will have output.
- When connecting three battery groups, ensure the voltage of each battery group is the same. If not, charge each battery separately before using in series. During discharge, the fastest voltage drop identifies the lowest battery group.
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

This protection board can be used as a power source for:
- Rechargeable massager
- LED emergency light
- 12V electronic devices
- Solar street light batteries
- Backup monitor power
- Other similar products
