Re: will it hurt my motor to run on low voltage?
Quote:
That was a way too soon to measure voltage and is way too low for such a short period of time after being on charge. The charger putting out 10A after being on the pack for 12 hours means the control board in the charger is bad or the ON-Charge voltage never climbed into the 44V to 46V range. What does the pack voltage read while on charge, after the batteries have been on charge for overnight? What does the pack and individual batteries read after the have sit without being charged or discharged for about 12 hours? |

1. The On-Charge voltage doesn't appear to be getting high enough to shut off charger. 2. We don't have an At-Rest voltage to determine the SoC the batteries are achieving. |

JohnnyB, I'm still working on my data. Working long shifts on a bridge! Thank you though!

Re: will it hurt my motor to run on low voltage?
After sitting all night the pack reads 38.2 with on board gauge. Charger is ezgo Powerwise QE, I believe it's charging all the way then shutting down( solid green light)

38.2V is a full charge for a 36V pack and when you get a steady green lite on a PW-QE, it is saying the charge is compete. You should be fine until you switch out the batteries for a 48V system. |

Re: will it hurt my motor to run on low voltage?
LOL SO yes Mike......he agrees, an you are good to go. the only thing that could make your pack a little bit more stable would be to get the one lower voltage battery (6.25) up a bit. other than that.....you are totally good to go.

Re: will it hurt my motor to run on low voltage?
You mean your chargers won't top off a pack that is already at 75-80% charged in a few hrs? Hmmm.... I guess I got a good charger or I'm a lier ....

What does come to mind is your charger may not be taking the pack to full charge voltage 44-46v. |
