Pro Level 4S Ternary Lithium Battery BMS Protection Board Built Tough With 120a Surge Breaker And Precision Dynamic Tuning For Hassle Free Double Sided Power Tube Mounting

Single pack 4S ternary lithium battery management circuit
✔️ 120A surge limit, 150A trip rating, 100mA passive cell sync

This single board locks in steady voltage while powering e bikes, solar racks, and jump starter boxes.

✅ 25uA quiescent draw cuts ghost load during long storage
✅ Exposed aluminum fins flush heat away from MOSFET clusters
✅ Conductive rubber pads bridge board gaps for faster cooling
✅ NTC probe routes direct data to controller for thermal safety

💡 How do builders keep stacked cells from degrading unevenly over years?
This handy management board runs passive equalizing cycles so your machine pumps maximum watts right out the gate.
- Soft trimming routine closes spacing once cells drift past tiny voltage gaps
- Instant fault isolation snuffs heavy surges before they burn wiring looms
- Deep cold disconnect blocks lithium plating worries during winter launches
- Sleep mode siphons near nothing so fresh juice stays topped off all season
