Voltage is OK. I use it for a 36v golf cart with 6 6v batteries. This is rated for 12V batteries so I said I have 3 batteries equal to 36V. The problem is the percentages are not accurate. It says it's 80% when in fact it's 90% at the current voltage. Programming is easier than people say, just follow the instructions. When it says disconnect to save, I pulled it off the back of the meter.
