I have a pair of 8 year old LFP 12V 100 Ah in my RV. They are still working great, but I realize they are getting older and am looking to modestly expand capacity. My RV has a battery compartment that is 25" W, 9" D and 10.5" H that just fit my two batteries. Most 280 or 300 Ah batteries (e.g. Chins or LtTime), at 9.45"D x 20.55"W x 8.58"H, are a little too large to safely fit in the space.
Recently, smaller form factor 300Ah options have appeared from a number of manufacturers, but all look relatively similar to this Epoch. The difference in overall size is remarkable. If you take the published case dimensions, the larger format Chins or LiTime batteries measure at ~1900 cubic inches, whereas the Epoch and similar are ~1200 cubic inches. My question is: what makes it possible to package 300 Ah of storage into a box that is 40% smaller? It's obvious that no one would make a product larger than necessary, so there must be some fundamental difference in what goes in them. I'd love a drop-in 50% boost in capacity, but am wary about what I might be giving up. TIA!
