Frequently Asked Questions

How long will it run my appliances?
It stores 1.28kWh, roughly 1.15kWh usable after inverter losses. See the What It Powers tab for runtimes on common loads.
Can I wire several together?
Yes — in parallel for more capacity at the same voltage, or in series for a higher system voltage. Use matched batteries of the same age and capacity, and check the specifications for the maximum number of units.
How do I charge it?
From solar through a controller set to a LiFePO4 profile, from shore power through an inverter charger, or from an alternator with a DC-DC charger. Do not charge below freezing unless the battery has a built-in heater.
