digilog.pk stocks genuine JK Smart BMS (JIKONG) boards — premium active-balancing battery management systems for Li-ion, LiFePO4, and LTO battery packs. JK BMS is regarded as one of the best DIY BMS solutions globally for large lithium packs, offering built-in Bluetooth monitoring, active cell balancing, and configurable parameters via the JK BMS app. Available in 8S to 24S, 40A to 200A configurations in Pakistan.
Why JK Smart BMS?
- Active balancing — transfers energy from high cells to low cells, unlike passive balancing which wastes energy as heat; extends pack life significantly
- Bluetooth monitoring — real-time individual cell voltages, temperatures, SOC, SOH, and current via iOS/Android app
- Configurable parameters — adjust overvoltage, undervoltage, overcurrent, and balance thresholds via the app
- Multi-chemistry support — Li-ion, LiFePO4, and LTO profiles selectable from the app
- High current rated — up to 200A continuous for demanding solar and EV applications
JK BMS Available
- JK BMS 8S 24V — 40A–100A; for 24V solar storage and medium-voltage packs
- JK BMS 13S 48V — 100A–200A; for high-performance e-bikes and scooters
- JK BMS 16S 48V LiFePO4 — 100A–200A; for 51.2V solar battery banks; most popular model
- JK BMS 20S–24S — for high-voltage EV and industrial storage
- JK BMS LCD display module — standalone display showing cell data without phone

Active vs Passive Balancing
- Passive balancing (DALY) — burns excess energy from high cells as heat; free but inefficient for large packs
- Active balancing (JK) — transfers energy from high cells to low cells; more efficient; extends pack life; worth the cost premium for 100Ah+ packs
