Now trying to help select batteries for the ComutaCar. I used Trojan T105s when I had it and the new owner is looking for the same since they are still in it but need to be replaced. One of our local EV gurus suggested money could be saved by using some from Sam's Club where they can be purchased for under $90.00. Please offer opinions...
I've used Sam's Club batteries. They are cheaper, but also don't last as long. You get what you pay for. :-)
If he's not going to use the car much (so they'll die of old age rather than from being worn out), then I'd go with the Sam's Club batteries.
If he plans to drive it every day (so cycle life matters), then I'd use the premium Trojan or USB batteries.
but not to upgrade to lithium. That would be overkill for a C-Car.
Probably so, unless you got the really cheap. You'd also have to replace the charger, and add a BMS (even more money).
Willie: C-cars are only 48v systems, and draw over 500 amps on a routine basis from their batteries. Most cheap lithiums would not like this kind of current at all.
