RXV Voltage Drop on hills - 1 yr old US BATTs

[Mccoy38]

I know these numbers add up to 51.22. I had to measure individually bc I have my controller off to get it checked out at the moment.

Couple questions.
Why can you not get specific gravity readings on batteries?

Charts for spec gravity have temp compensation. Also use quality,not cheap automotive floating ball spec meter but good one.

Confused to are you using automotive charger on batteries or useing carts charger allowing it to fully charge and shut off on it’s own.

Also can you check pack voltage “before” you leave for course,not after batteries are charged.
Along with pack voltage under load and each batteries voltage under load readings.

would help knowing specific gravity after use on golf course.

FYI although probably not your problem is some 48 to 12 volt convertor do draw an amp or two even when not used. This draws down batteries when not being used.

Some converters can be wires to activate off key switch or like mine had to install on/off toggle for convertor😊
