Battery Meter question

LPnTX

I installed a 48V LED bar battery meter on my 07 Drive and drove the crap out of it and the bar never moved off full. Then as I was heading home it went straight to the lowest bar and started flashing red and yellow. the LED bar never moved to half charge just straight to the last bar. The cart began to slow down and I barely made it home. I charged it all night and the charger indicated it was fully charged, however, the meter is still flashing red and yellow. I took it out and played 9 homes and cart seemed to have full power but still flashing red and yellow. It is wired to the key switch so it comes on when the key is turned on.

Any ideas what is causing this? Could it be a bad meter or a wiring issue?

Those meters are almost useless. Get one that reads volts.

The problem with those meters are you don't know what the actual voltage is. On a 48v cart you never want to go below 50% SOC state of charge. That number is 48.4v. Full voltage is 50.9. You really need, IMO, a digital numeric soc meter. That way you know exactly what your voltage is and you won't be doing damage to your expensive batteries. I got mine from ScottyB at cartsunlimited.net. It reads dead on with my handheld dvm.

First, the 10-led bar graph meters have a bad reputation for inaccuracy under anything but perfect battery condition. Second, you did not get the original Curtis energy meter, but a "knock-off" (at least the Curtis comes with documentation to explain what its doing & why). Sorry, you may have wasted your money.

The Curtis 5 bar meter was OEM equipment on Ezgo for many years. They were deceitful. I tested the pack voltage as each bar dropped off the lighted scale and to my surprise the pack was below 50% depletion when the second bar dropped off the lighted scale This led me to seek out a digital meter for my own carts. Initially only expensive industrial meters were available but now inexpensive meters are equally waterproof & accurate.
