Frequently Asked Questions

Does a 100Ah AGM battery give the same runtime as a 100Ah Lithium battery?

No. A 100Ah AGM battery only delivers 50 usable Amp-hours before dropping voltage below safe limits. A 100Ah Lithium battery delivers all 100 usable Amp-hours, effectively doubling your time on the water.
