RXV with Lithium Batteries
Have a 2014 RXV that I converted to Allied Lithium batteries a year ago. I converted to the 50 amp hour batteries. Everything was great till about two months ago when one battery went zero volts with 60% capacity left. Then another battery went to zero volts. I found out that this is the internal BMS system acting like a circuit breaker. Allied replaced the two batteries and then a third battery failed!! Anybody else out there experiencing these failures?

Re: RXV with Lithium Batteries
old post I know, but I am having same issues.
2015 Rxv 48V stock curtis controller. im on my 3rd lithium battery pack in 2 years. here is what I have: ePOWER4803E are integrated golf car battery systems with a 48V 3KWh Lithium Ion battery pack. The battery configuration is a 16s1p 60Ah pack. It is typically programmed with 80%DOD, or 2.4KWh usable storage capacity. 1st pack dropped 6 cells in 6 months 2nd pack dropped 9 cells in 3 months. last pack lasted 2 months before dropping 9 cells. Total lock up on cart when voltage drops. |
Re: RXV with Lithium Batteries
IMO 60AH is not sufficient and it's easy to overcurrent / overdischarge that small a pack. Not sure who's batteries you are using but early failures are unusual with high quality properly sized Lithium packs.

Re: RXV with Lithium Batteries
thanks thats is my thinking..
i am upgrading to 100ah |
Re: RXV with Lithium Batteries
I'm having BMS issue with my 150Ah pack, so it is not the size. I think I'm going back to the lead acid.

Re: RXV with Lithium Batteries
I have thought about going back as well,
A few more years may be needed to perfect the lithium golf cart battery |
Re: RXV with Lithium Batteries
I think that what’s happening is the power demand from the RXV motor is so great that the computer can’t handle the voltage demand and then drops cells but what do I do I know except this is my 4th pack in 2 years

Re: RXV with Lithium Batteries
I've been waiting for the Roypow S51105P to become available at my local dealer. I think it's made to handle the extra regen power surge but not the peak demand load.
Any thoughts on that? I hate to throw good money away. |
