The 4S 10A 14.8V 18650 Li-ion BMS Protection Board manages four lithium cells in series. It regulates voltage and current during charge and discharge cycles. This 14.8V Li-ion BMS module prevents cell damage from electrical faults in DIY electronics projects.
Key Features
- 4-Stage Safety: Monitors overcharge (4.25-4.35V) and over-discharge (2.3-3.0V) thresholds. Cuts power to prevent permanent cell chemical degradation.
- 10A Continuous Current: Supports steady 10A output with 20A peak surges. Handles high-draw loads like DC motors without tripping.
- Automatic Recovery: Resumes operation once short-circuit or over-current conditions clear. Eliminates manual resets after temporary wiring faults or surges.
- Compact PCB: Measures 35x35x3.6mm with under 100mΩ internal resistance. Fits into tight battery packs without generating excessive heat.
- Low Quiescent Current: Draws less than 30uA during standby mode. Minimizes battery drain during long-term storage in high humidity.
Frequently Asked Questions
How to wire 4S 10A BMS?
Connect B-, B1, B2, B3, and B+ to battery taps in sequence. Use the P- and P+ terminals for both charging and load output.
Can I use 4S BMS for 18650?
This board works specifically with 18650 Li-ion or Li-po cells. Ensure the total nominal voltage matches the 14.8V requirement.
