2009 36v EZGO Batt. and Charging issues

cm5217

Hello guys first let me say sorry for the long post kinda new with this golf cart thing Im a car guy anyway here goes....I have a 2009 36v EZGO that i take to nascar races and Harley rallies and other camping trips also use it some in the yard and around the house. I just came home from the Bristol race and its the second year in a row that the cart would not charge on my RV Gen. but i could go up the way to a street power plug and it would charge...during all this i was checking the batts with my meter and I did find one of my Batts is bad when its fully charged the other 5 read 6.5 this one reads 6.1 and after riding for a few min and i mean a few min the bad batt went too 2.5 and the other 5 where 6.3 so i know i need a new batt. Now for more info the bad batt is the first one in the pack meaning it has the hot wire going to the controller. Also i know why that battery is bad i ran a couple of them out of water I didnt realize that the water boils every time you charge so didnt check the water level soon enough. So as for the charging question do you think i have a problem with my charger or RV converter? Not really thinking the RV as all my other electronics work fine on the RV Gen set so i am thinking the charger has a problem...when i plug it in it tries to start charging it will blink like 3 or 4 times then go out for a couple of seconds then do it all over again and again but never charging i can hear the relay in and out in and out. Now for the next question I am not real happy with the performance now i know i have a bad battery but as far as hills this thing is a turd so my questions is what do i need to do to get this thing better on the hills without losing too much speed..I have been looking around on the internet and found motor and controller combos for like a thousand buck do i really need a new motor or can i just get a bigger controller? again sorry for the long post and any help your guys can give me on the charger thing and any recomdations on upgrade would be cool..

Welcome to BGW

Is it possible the charger isn't getting enough amps to do its job? It needs a 25 amp receptacle I believe. I'd think at least a 20. If the genny is loaded up with other stuff it might not be getting enough juice. Try unplugging or turning off everything else and plug up only the charger.

As far as more speed...Do you have a PDS cart or series cart?

I am gonna agree and say your gen is not putting out enough to operate that charger and your other accessories. I tell customer to make sure they are on a stand alone 20amp breaker at their house. No extension cord unless is as big as your thumb.

As far as cart and speed. We need more info on drive system. fleet or pds.

Sorry guys my cart is a PDS ( i think...it has the tow/haul switch under the seat) and as for the RV Genny i did try turning everything off but the charger i mean it was still charging the RV Batts but thats all that was on and still no charging now i am not sure if i have 15 amp plugs or 20 amp plugs i guess i need a 20 amper for the charger to work???

I also have a question about the Battery i think is bad...let me tell you what its doing..first its the number 1 batt in the pack and when i do get the cart to charge it never gets fully charged. the other 5 get to 6.6-6.7 and the first one is 6.3-6.4. then after driving around for a while the other 5 are 6.4 and the first one is 3.5 or lower. so does that tell you that the first batt is bad?

Someone else can tell you if your battery is bad but it sounds like it is.
Some more info on your RV could maybe help diagnose your charging problem. What is the capacity of your RV gen? ______watts or ______killowatts (Kw). You said your RV battery charger was running while trying to charge the cart......the RV charger can use as much as 10-12 amps......mine does. The other thing that MAY be a problem is if you were plugged into a GFCI receptacle on the RV. You probably were as the outside plug is definitely a GFCI receptacle.
In one of your posts (first one) you asked if you could have a problem with your "RV converter". is it a combo unit.....like a charger/converter? A RV converter just converts 110vac to 12vdc and whether the converter is working or not would have no bearing on your cart charger. `
