Well-built batteries, but no customer support
These batteries appear well made and arrive in solid wood boxes, and their compact size is a plus. However, compatibility issues arose with Sunny Islands inverters, which dropped the load once the batteries reached full charge despite years of trouble-free operation beforehand. Customer service is a major concern: no response by phone or email, and extensive forum searching yielded no solution. Buying two matching inverters introduced a new problem with one unit, again with no support available.

- + solid wood shipping boxes
- + compact size
Cons
- − no customer service response by phone or email
- − compatibility issue with Sunny Islands inverters
- − inverters dropped load at full charge
- − problem with one of the purchased inverters
