BMS - Medium Pack (5S to 13S)
digilog.pk stocks medium-range BMS protection boards for 5S to 13S lithium battery packs — covering 18V (5S) to 48V (13S) nominal voltages. These BMS boards are the backbone of e-bike battery packs, electric scooters, power tool batteries, and mid-scale solar storage systems in Pakistan. With current ratings from 20A to 100A and built-in cell balancing, they keep your lithium pack safe and healthy for thousands of cycles. Why Medium-Pack BMS? E-bike voltage range — 10S (36V) and 13S (48V) are the standard voltages for electric bicycle motors in Pakistan High current handling — 30A to 100A continuous for powerful hub motors and mid-drives Cell balancing included — passive balancing maintains cell equilibrium across all series cells Temperature protection — NTC sensor input cuts output if pack overheats under load Available Configurations 5S BMS — 18V nominal; for power tool replacement packs 6S BMS — 22.2V; for drone packs and medium power tools 7S BMS — 25.9V; for specialty applications 8S BMS — 29.6V; for industrial portable equipment 10S BMS — 36V nominal; standard for entry-level e-bikes 13S BMS — 48V nominal; standard for high-performance e-bikes and scooters in Pakistan Related Categories See smaller packs at Small Pack BMS (1S–4S).
