Voltage Platform & Load Class — Where This BMS Fits
📊 20S (60V) — Heavy-Load Applications at 200A
The 20S platform at 60V covers electric sightseeing vehicles, electric tricycles, and UPS systems in the heavy-load category (150–200A). At 200A with 2A active balancing, this BMS delivers maximum cell consistency through demanding daily cycles.
⚡ 2A Active Balancing — Faster Equalization, Longer Pack Life
At 2A, the active balancer equalizes cells fast enough to keep them matched during the charge cycle — tighter voltage spread, more usable capacity, and slower capacity fade over the pack's lifetime compared to 1A models.
Who Is This BMS For?
- 🛴 Electric sightseeing vehicles (48V–60V, heavy-load)
- 🚲 Electric tricycles and light cargo EVs
- 🔋 UPS & backup power systems (24V–60V)
- 🏭 OEM manufacturers of 24V–60V 200A lithium battery packs
