im desperately trying to find lifepo4 batteries for my wheelchair. it calls for 2 agm 12v 55ah. all im finding is 50ah and 20ah lifepo4's. my question is can i link a 50ah and a 20 ah battery in parallel for a total of 75ah at 12v to my chairs controller. So total batteries to be used is 2 50ah and 2 20ah. this upgrade sounds feasible to me. Any ideas people? Size restriction is a problem otherwise id go with bigger batts. i have 2 12v 55ah agm right now and they suck. lifepo4 is the only way to go in my mind. so do i get a couple 50ah and 20ah or do i build my own batteries from scratch. I have room to add the extra 20ah batts. ill have to custom mount the 20ah batts. someware on my chair but its doable. Ideas? Links? Thanks beforehand for your comments.
