Internal BMS Battery System
The most affordable and easiest to install for a basic camper van electrical system that charges with solar, when driving through DC-DC chargers and also through an inverter/charger when you have shore power.
External BMS Battery System
If you need a fairly large power system, and therefore large batteries with high amp hour capacity, you start to benefit from batteries that use an external BMS which allows you to fit more battery storage in the same footprint.
Dedicated Secondary Alternator
If you need the best off-grid capability with large “loads” like air conditioners, this is the most reliable and powerful way to keep your battery bank charged up.
