Maintenance-free

Maintenance-free

No fluid refill, no memory effect, lowers daily upkeep.
 Multi-layer protection

Multi-layer protection

Built-in over‑temp, over‑current, over‑voltage, and short‑circuit protection.
Flexible strings configuration

Flexible strings configuration

Supports various series/parallel combinations, flexibly adapting to different voltage and capacity requirements without hardware changes.
Direct off-gas venting

Direct off-gas venting

Each module features a dedicated vent port that can connect to an external exhaust line, directing any gases generated under abnormal conditions directly out of the vessel, eliminating gas accumulation risks.
