Using a wheelchair and wanting to convert to LifeP04, or get the best out of your AGM/Gel?
Look into the site run by a paraplegic engineer, (Burgerman) who has a forum and done plenty of conversions. Please note that there are NO SALES on custom chairs, battery builds etc. Many of the users live the life in the chair, so not a lot of speculation.
and of course a forum that goes into detail about it all:
To save time: The users have a different application than us - theirs is motive power, not battery storage per-se. They do NOT use "drop-ins", but rely instead mostly on Revolectix PL8 chargers with custom firmware and balancers on custom batteries built from individual cells. They also do not use prismatics, as they are not totally suited for their motive-power needs.
They also don't use a BMS - the only balance occurs during charge, otherwise when out and about the battery is naked. The reason for this is that for the huge currents they pull, a typical BMS would shut down as they are trying to cross the street and get up a ramp.
Of course plenty of info on GEL and AGM. Back in the day the Optima and Odyssey AGM's were the thing to mod the chairs with. Still valid if you go this route.
Just wanted to point this valuable resource out even though their application is different than ours. Some threads are really long, so you may be tempted to read them backwards.
Anyway, if you live this life you may find the info there as well as here enlightening. Again - NO SALES as cool as his custom chairs are.
