My RMartin EVD VRLA will soon need new batts I suspect. I'd like to get Lifepo4s instead of VRLAs so that I can go more years without having to replace the batts again. But I'd like to do this as cheaply as possible. I'm assuming I won't need a new charger, controller, dc/dc converter, or motor if I get 12volt/50ah Lifepo4 battery packs? Hopefully that is true. I understand however that I would want a BMS for the Lifepo4s.
Now, in my fantasy world I would just swap out the 5 VRLA batts with 5 Lifepo4s having the same physical dimensions. Is that possible? Where could I purchase such batteries?
If that isn't possible, then any good prices out there on new BB EB50-12 batts? From my research they seem pricey. Best I could find was around $750 for 5 batts including shipping (from zbattery.com). The UB12500 batt is supposedly a cheaper replacement for the BB EB50-12. Are those any good?
Thanks in advance.
