The 3S 10A 12V 18650 Lithium Battery BMS Module regulates three series-connected cells for 12V power. It monitors voltage levels to prevent cell damage during charge and discharge cycles. This 11.1V protection board manages 10A continuous loads for DIY battery packs.
Key Features
- Overcharge Protection: Voltage cutoff between 4.25V and 4.35V per cell. Prevents battery swelling or fire during charging.
- Short Circuit Recovery: Automatic circuit restoration after clearing the external fault. Eliminates the need for manual fuse resets.
- Low Quiescent Current: Standby power draw remains below 30uA. Stops battery drain during long-term storage periods.
- High Discharge Rate: Handles 10A continuous and 15A peak current. Supports sudden power spikes from small motors.
- Compact Footprint: Measured dimensions of 50x16x1mm fit tight enclosures. Integrates easily into standard 18650 battery holders.
Frequently Asked Questions
How to connect 3S 10A BMS to 18650 battery?
Solder B-, B1, B2, and B+ to the battery string in sequential order. Incorrect wiring will result in zero output voltage at the P+/P- terminals.
What is the price of 3S BMS in Bangladesh?
Market rates vary depending on component stock in Dhaka electronics hubs. Current pricing reflects the standard 12.6V lithium charger module cost.
