Quality battery for off-grid expansion
This battery was added to an existing off-grid power station using a modified cable. After charging both units to full and running a near-complete cycle, compatibility appears good, state of charge stays relatively close, and total capacity nearly tripled. The simple design suits installation under a counter where no display is needed. The mobile app is basic but shows state of charge and other key information; it lacks features such as time remaining and time to full charge. Recommended as a quality battery.
Pros
- + good compatibility with existing power station
- + capacity nearly tripled
- + simple design
- + mobile app shows state of charge and key info
Cons
- − mobile app lacks features like time remaining and time to full charge
