Hi. I am a first time ev owner. I have a 08 gem e4. My battery level indicator drops one bar at a time down to 50% then blinks and drops to one bar. I am not sure how old the batteries are or how much life they have in them or if this may be a charger or relay issue. Any advice would be appreciated. Thanks.

Is that with new batteries? Have you ever continued driving or have you always recharged?

Old batteries.
Drive 1/2 mile home and recharge.
My 2010 with new batteries seems to work fine. I never ran it down low enough to see if it jumps to empty. Have run it down to 1/2.
The 2008 goes down to two bars from full and the jumps to empty.

Old batteries and at least 1 bad cell?? Does the charger lights say the batteries had a complete charge? Barry

My 2007 has the exact same problem. The batteries are under a year old and the voltage is fine on each battery even after they are ādischargedā.
Have either of you found a solution? Iām wondering if itās the contactor or motor controller possibly?

First of all Iām not an expert. New batteries can have bad cells. I had a set of batteries (gell) that went bad. When measuring the voltage as a group the pack looked fine. The state of charge bars showed a full charge. The battery charger was blinking red that said there really wasnāt a full charge. I thought the charger was bad. It wasnāt. It was telling me it couldnāt charge the batteries all the way. I kind of figured there was a bad battery (or more than one). I found the batteries all measured within .01 of each other. Some high some low. I couldnāt find a bad battery. Polaris charged me $35.00 to tell me every thing was OK with the batteries. They didnāt own and still refuse to by the Gem recommended battery discharger/tester, ($800.00). I finally installed a BattSix system. I noticed one of the batteries was always .01 lower than the rest. You have to have a way of real time constantly checking the batteries while in use. I bought a new battery and replaced the low one. Problem solved. The charger showed a green light and things were good. Good luck, Barry.
