Modern lifepo4 batteries are a game changer for camping vehicles due to their ability to store much more energy than classic AGM or GEL batteries. There is a lot of discussion about the proper way to install the new type of batteries: going from "just swap" to "rebuild the electric wiring completely". The "just swap" position is probably right as long as the ampere hours of the new battery are not too far away from the old one. E.g. swapping a 90Ah AGM for a 100AH lifepo should be OK - as long as the size (esp. the height), the mounting and the type of generator in the motor fit (problem "intelligent generator). Swapping with a new 300Ah lifepo4 will probably require more work. First, the new battery - especially when close to being empty - can charge at a huge rate. This might damge the generator or could cause problems when the cabling is to thin. Second: such a huge battery needs a lot of solar power to charge and this will probably require new chargers, cabling etc. And that means you are suddenly going from a rather simple architecture with one main switch to something with many generators and with the positive and negative busbar in the center.
