batteries die quickly
I have supposedly 2 1/2 year old batteries trojan 875 six of them. The cart runs great but the battery gauge runs down in 30 min. If I unhook the controller for a couple minutes and hook it back up, the gauge goes back up, but it still runs down fast. I took my F&R switch off and a lug was almost completely burnt off and not making contact. Would the F&R switch do this or is it the batteries or maybe controller?

Re: batteries die quickly
A few different problems could cause this. Or a combination of problems.
First off the battery voltage under load is unknown, low voltage under load causes high amp draw which causes F&Rs to fail. Motor brush problems can cause high amp draw. Oversized tires & loads or undersized components can cause excessive heat. So we need more information to nail your trouble down. |

Re: batteries die quickly
I am new to the electric carts. I had planned on replacing most of the electronics with new HD stuff from PlumQuik. How do I check the batteries under a load? Special tools or is there any other way?

Re: batteries die quickly
When charged I have 8.4 volts at each battery and when it first says they are low, i still have around 8 at each battery.

Re: batteries die quickly
8 each battery is almost dead. Sounds like you need new batteries. They are not giving you much capacity.

Re: batteries die quickly
Clip volt meter leads to batteries, drive cart uphill, under load to get the best read on batteries under load. Post results. 50.9 12 hours after charger turns off.

Re: batteries die quickly
Full charge should read 8.49V
50% should read 8.07V As a general rule never run your batteries down under 50%. Whole battery pack 100% 50.93V Whole battery pack 50% 48.41V As a general rule never run your batteries down under 50%. |
