Scotty B digital volt meter in 2010 Precedent

55BigBlock

I just got my ScottyB digital volt meter installed. The toggle switch in the picture cuts it on and off. Works great. My pack fully charged is around 50.3 volts. I headed for the biggest hill (not too big, but long) and the voltage dropped to 45.9 momentarily but then settled around 47.5 going up to the top. On flat ground, wide open, it is about 49 to 49.5 volts. They are 2010 batteries. What do you think?

the settle volts are a little low, after batteries settle around 12 hours off the charger, they should read 50.93 100% charged

Thanks for the reply. The settle voltage is 50.3. It had been off about 8 hours. I had checked the chart and they get to around 90%. I guess their age is a factor.

Your voltages under load do not look bad at all to me. I have new batteries and will drop down in the 44v range when starting on a fairly steep incline.

charge it, after it is fully charged let it sit a half hour, or drive it around the block and charge it again, and again, keep an eye on the water levels, distilled water only, charge it like that for a week and it might bring them batteries back up
