Very good performance. Able to take a high charge rate and likes higher voltages than most other VRLA's (up to 7.5v for 6v). Only negatives I see are: not md in USA and very expensive.<br>

>>To further qualify my statements, the inverter will start the pump without issue, but I should echo the warnings by others that if there are other loads present, especially other motor loads that could start concurrently, you may experience issues.
