Frequently-Asked Questions
Can this charger be left connected full-time?
Yes. It automatically switches to float mode when the battery is fully charged, making it safe for long-term maintenance.
Is it compatible with non-LiFePO₄ batteries?
No. This charger is engineered specifically for 24V LiFePO₄ batteries and should not be used with lead-acid or other chemistries.
Where should I install it?
It can be mounted in wet or enclosed spaces like bilge compartments, battery bays, or under seats—thanks to its IP67 rating.
Will it work for charging two 12V batteries wired in series?
Yes, as long as the combined system voltage is 24V and the batteries are LiFePO₄ chemistry.
