A battery capacity question for the hive mind

[The Artilleryman]

Not strictly a moho question, but here goes as plenty of you have experience of LiFePO4 batteries.

Need to replace 2 fla's (2 x 100ahc), but I'm limited to battery size should be 110 size(315 x 175 x175) although I can modify a little but to 190 wide & 220 high.

Choice's are :- 2 x 100ahc fla, 2 x 75ahc LiFePO4 bluetooth (no mods), 2 x 100ahc LiFePO4 without BT (with mods).

Now I know that 2 x 75ahc LiFePO4 will give me slightly more usable charge and will cost about the same as 2 x fla as I'm looking at these.

If you speak to RogerIvy of offgrid power solutions he will be able to advise you and may be able to build a battery to suit your needs.

The Ecowothy 100amp lithium's are £152 on eBay. I have 2 fitted and aware quite a few other funsters have used them.

Fogstar and Roger mentioned above have built custom boxes and then cram as much AH capacity as they can to fit under seats etc..... so not strictly restricted to 'normal' battery sizing.

We also have 2 x ecoworthy 100ah lifepo and 3x 100ah ecotree on 2 seperate banks. No issues with either type.
