Description
Looking for a reliable 3s 20a bms for your DIY electronics and power projects in Bangladesh? The 3S 20A BMS 12.6V Lithium Battery Protection Board is an essential component designed to safeguard your 18650 Li-ion battery packs from overcharging, over-discharging, over-current, and short circuits. At HTE Bangladesh, we provide authentic components to ensure your custom power setups run safely and efficiently. Whether you are building a portable mini-ups, a 12V DC power bank, or upgrading a cordless drill motor, এই 12.6v lithium battery charger module টি আপনার ব্যাটারির দীর্ঘস্থায়ী সুরক্ষা নিশ্চিত করবে। Compared to basic protection circuits without recovery, this automatic-recovery 3s lipo battery bms is better suited for high-drain applications because it automatically resets the output once the fault condition is cleared.
Key Features & Benefits
- Continuous Discharge Current: Delivers up to 20A continuous working current, ideal for high-drain devices like 3s 18650 bms for drill motors.
- Overcharge & Over-discharge Protection: Prevents cell damage by cutting off power when voltage exceeds upper limits or drops below safe thresholds.
- Short Circuit Protection: Built-in recovery mechanism automatically restores output after a short circuit is removed.
- Balanced Charging Support: Ensures equal charge distribution across all 3 cells, maximizing overall battery pack lifespan.
