Battery voltage under load

You have a 48v pack, within it, there are a total of 24 cells (if you have 6-8v, 4 cells in each battery...or 8-6v batteries 3 cells in each battery), and you shouldn't allow your pack get below, under load, 1.75v/cell. SO for your 48v pack, UNDER LOAD, shouldn't get below 42v.


IF you had a 36v cart, you would only have 18 cells X 1.75V = 31.5V minimum voltage while under load.

Thank you. Old thread but really useful information to us newbies.

Oldie but goody.
Perfect example of symptoms when to replace batteries.
Remember to charge after every use and let batteries “ complete” charge cycle.
Giving batteries their complete charge till charger shuts off is important 😊

Complete charge cycles ought to be used whenever possible and practical, but partial charge cycles in between complete charge cycles are helpful also. In a nutshell, some charging is better than no charging while cart is not being driven.

The benefit is more obvious with service carts like parts chasers and people movers. Putting on charge for 10 minutes while driver takes a break or an hour for lunch helps the cart run better towards the end of the shift.

Of course opportunity charging isn't always readily available to us when we are out and about on our carts, but if you do have a chance to charge the battery for a few minutes, do it.

Have to admit as a newbie to golf carts learned a lot from one of my first post back then. As usual this community provided a wealth of info to learn from.
