BMS - Battery Management Systems
digilog.pk stocks Pakistan's most comprehensive range of BMS (Battery Management Systems) protection boards — covering 1S to 24S lithium cell configurations for Li-ion, LiPo, and LiFePO4 battery packs. Whether you're building a DIY power bank, e-bike battery, solar storage system, or industrial UPS, a BMS is essential for safe operation — it protects against overcharge, over-discharge, short circuit, and over-temperature. We stock all major brands including DALY, JK Smart (JIKONG), and generic protection boards at the best prices in Pakistan. Why Every Lithium Pack Needs a BMS Overcharge protection — cuts charging at 4.2V/cell (Li-ion) to prevent thermal runaway Over-discharge protection — disconnects load at 2.5–3.0V/cell to prevent cell damage Short circuit protection — cuts output within microseconds of a short event Cell balancing — passive or active balancing keeps all cells at equal state of charge Temperature monitoring — NTC thermistor input stops charging/discharging when too hot BMS Sub-Collections Small Pack BMS (1S–4S) — for power banks, drones, small UPS, and RC toys Medium Pack BMS (5S–13S) — for e-bikes, power tools, and 18V–48V battery packs High Voltage BMS (14S–24S) — for solar storage, large UPS, and industrial energy systems DALY BMS — reliable common and separate port BMS in 3S–24S variants JK Smart BMS (JIKONG) — active balancing BMS with Bluetooth monitoring LiFePO4 BMS — specifically calibrated for LFP chemistry (3.2V nominal cells) E-Bike & Scooter BMS — high-current rated with heatsink for 36V–60V traction packs Related Categories Pair BMS boards with cells from Batteries & Chargers.
