Battery and Inverter FAQ
Our LiFePo4 batteries are considered to be safe, non-flammable and non-hazardous by international and federally regulated standards.
Our Batteries are commonly used for marine, RV and golf cart applications. You can use our lithium batteries for any application that would normally use a single or multiple lead acid, GEL or AGM batteries.
After you take out your old batteries, place our batteries in the same way. You can use the same cables to reconnect into the Lithium Battery.
Our lithium ion technology uses the latest and most advanced built-in battery protection system to prevent damage to the battery. You may utilize a standard charger for our products, although in some cases a lithium charger may be required to charge the batteries.
The industry standard house battery size used in most RVs, Campers, and #VanLife builds is the 12v 100Ah battery. This is a drop in replacement for AGM and most lead acid batteries. If you are charging off your engine's alternator we recommend a Victron DC-DC smart charger. If charging off solar panels we recommend a Victron Smart Solar charge controller, or if you have a solar charge controller choose the lithium setting. A handy size chart for number of batteries
