How this product fits your system

This battery stores energy for your RV or van; it does not supply household AC by itself. A compatible inverter is needed for AC appliances, while your 12V appliances use protected DC distribution. Match the battery's voltage to your complete system before comparing capacity.

3840.0Wh nominal energy. That is stored energy before reserve and conversion losses. Runtime depends on everything you run and the charging that actually arrives during your trip; amp-hours alone are not a runtime promise.

Charging and cold-weather use

Solar, alternator and shore chargers share the battery's permitted charging current. Their combined settings must stay within the battery manual, including temperature limits. A battery with low-temperature cutoff does not necessarily heat itself.

The recorded maximum charging current is 300A per battery; this is separate from the discharge rating.

This model records a self-heating feature. Check its activation temperature, power source and operating conditions in the exact model manual.

Bank connections and installation

Use matched batteries and the manufacturer's permitted bank arrangement. Series raises voltage; parallel raises capacity at the same voltage. A permitted connection count does not establish cable size, current sharing or fuse interrupt capacity. Check the case dimensions, mounting orientation, terminal torque, ventilation and your vehicle payload before ordering.
