Version 2 is upgraded with an advanced Active Cell Balancing technology, which maximizes the battery's lifespan and efficiency better than the passive balancing in Version 1.
This is the core technology that dictates battery longevity! While standard batteries use "passive balancing" (which wastes excess energy as heat), our Version 2 features advanced Active Cell Balancing. It smartly and losslessly transfers energy between individual cells. This ensures you can utilize 100% of the true capacity, enjoy faster charging, and get a significantly longer overall lifespan.
It is equipped with a dual-safety system featuring a 100A Smart BMS and a built-in 125A circuit breaker to protect against overcharging and short circuits.
It is absolutely safe for indoor residential use. The battery is protected by a rugged metal casing (IP54 rated) and features a Double Safety Lock system: an advanced 100A Smart BMS combined with a 125A physical circuit breaker. If the system detects grid anomalies, extreme temperatures, or a short circuit, it physically cuts off the power in milliseconds to keep your home safe.
