Description
A 12V 392Ah LiFePO4 marine kit for 12V house banks, electronics and trolling setups that need serious capacity. One sealed IP67 pack replaces heavy lead-acid, delivers its full rated capacity, and ships with the charger, console gauge and helm power switch so the swap is done in one go.
The Rhino guarantee
If the battery fails for any reason within 8 years, Lithium Rhino replaces it at no charge.
8-Year Warranty
10+ Year Life
6,000+ Cycles
App Connected392Ah of 12V lithium in one sealed pack. Enough capacity to run electronics, fridges and lights for days, not hours.
Serious technology, built to take a beating
Three reasons the switch pays off on the water.
Power for the whole trip
Lithium Rhino builds the marine line in several voltages and capacities, so you can size the pack to the way your boat is actually used.
Smart sleep modes
The pack drops into light sleep after 30 idle minutes and deep sleep after 7 more days, so stored charge is still there next trip.
Monitor it three ways
Read charge on the battery's color screen, the console gauge, or the free Rhino app. A helm button switches the pack on and off.
