High Voltage BMS 14S to 24S in Pakistan | stem.pk
stem.pk stocks high-voltage BMS protection boards for 14S to 24S lithium battery packs — covering 48V (14S LiFePO4) to 87V (24S Li-ion) nominal voltages. These high-voltage BMS boards are designed for large solar storage banks, industrial UPS systems, electric vehicle traction packs, and high-power energy storage applications. We stock boards from proven manufacturers with current ratings up to 200A for the most demanding applications in Pakistan.
High-Voltage BMS Applications
- Solar storage systems — 16S LiFePO4 (51.2V nominal) is the standard for home solar battery banks
- Industrial UPS — 48V lithium to replace lead-acid rack batteries in server room UPS systems
- Electric vehicles — 20S–24S packs for higher voltage EV powertrains
- High-power inverters — large lithium banks feeding 3kW–10kW pure sine inverters
Available Configurations
- 14S BMS — 51.8V Li-ion / 44.8V LiFePO4; for 48V nominal systems
- 16S BMS — 59.2V Li-ion / 51.2V LiFePO4; most common for 48V solar and UPS
- 20S BMS — 74V Li-ion; for high-voltage EV applications
- 24S BMS — 88.8V Li-ion / 76.8V LiFePO4; for high-voltage energy storage

Common Applications
- Home solar storage — 16S LiFePO4 pack + DALY 100A BMS + MPPT controller — see Solar & Inverter
- Server room UPS lithium upgrade — 16S Li-ion replacing lead-acid 48V battery strings
- Large inverter battery bank — 16S 100Ah LiFePO4 + 16S BMS for 5kW off-grid inverter
- Industrial energy storage — modular 24S packs with 200A BMS for factory backup power
How to Choose
- Chemistry first — LiFePO4 (3.2V/cell) or Li-ion (3.7V/cell) determines voltage per cell count
- System voltage — match to your inverter or charger's rated input voltage
- Current rating — size to peak discharge current of your inverter load
- Brand — DALY and JK Smart (JIKONG) recommended for reliable protection and Bluetooth monitoring
