Pros
- Independent test measured about 6% more capacity than rated
- Standard Group 31 footprint drops into most marine and RV battery boxes
- Pairs up to four in series or parallel for 48V or larger banks
Cons
- No Bluetooth, so state of charge needs a separate shunt monitor
- No low-temperature charge protection mentioned, so charging below freezing must be avoided manually
