2015 EZ Go RXV Died

[opelikamike]

I have a 2015 EZ Go RXV with 4 - Trojan T-1275 batteries with C8 date code (March 201.

Bought used in 2020 and it has run flawlessly. I check battery water and battery voltage every 2 weeks. Cart is charged after every use.

yesterday, riding home from our club it just died. Turned key to off and back to F and cart would move forward ever so slowly. Suddenly heard a pop. Stopped and looked under seat and a battery cap had blown off top of one of the batteries.

Neighbor helped me tow 1/2 mile to house.

Battery voltages were all 12.8 or slightly higher when I got to house and all batteries had water above plates.

Haven't tried to run cart. Headlights come on. Haven't put it on charger. There is a faint electrical smell under seat.

Called a mobile golf cart service (he won't be out till Monday) and he says batteries are bad. I have no way to load test batteries.

I don't want to damage anything by trying to operate it.

Any ideas on why it might have suddenly failed after no hint of trouble?

Thanks

I agree that is most likely a bad battery since one blew it's top. You can monitor the voltage when you try to drive the cart. If it drops a bunch then you can be sure you have at least one bad battery. The "POP" was a Hydrogen explosion - never a good thing. It often cracks the battery case as well as blowing off one of the caps.
