So, I'm getting a new camper and have the opportunity to set everything up from scratch, rather than changing my current "aged" system.
Without entering a debate about battery types, I'm leaning towards the LiFePO4 type of battery due to capacity and weight advantages. There is so much conflicting info out there from the lovers and haters, so I just have a few simple questions:
1. Any advantage/disadvantage of using 3 x 60Ah or 2 x 90Ah to get 180Ah, particularly regarding battery management?
2. A couple of suppliers seem to be
EV- Power and
EVWorks. Any
feedback on these?

Hi Jos. As others have said, the disadvantages of 2 or 3 cell lots are size,weight, cost and monitoring. The one advantage is if in the unlikely instance that a cell did fail, it would be cheaper to replace. I have 4x3.5v 200ah cells. They weigh 42Kg all up with supports and cell connectors but replaced a single 100ah AGM that weighed 38kg. I bought
mine from this fellow who, along with his wife, are very knowledgeble and efficient. Because of our dollar devalue lately they have gone up slightly in price. LiFePo4 are becoming more and more popular. Bushtracker Caravans now fit them as an option. Regards,Bob

The specifications show these types of batteries to be top performers.
If I was in the market for a new battery I’d seriously consider them.
Generally with any deep cycle battery – comparing one single large battery to two half size batteries, adding up to the same capacity – the larger single battery will have the longer life span. The same applies to 3 smaller batteries compared to 2 large etc.
Another advantage, if you have the charger capacity, is this type’s ability to charge at a very high rate, compared to a standard AGM’s (If I read their specifications correctly).
