Zapino Battery Report - 1000 miles

Posted by Max Dunn Wed, 12 Mar 2008 00:18:00 GMT

I have put over 1,000 miles on my Zapino since we got it last August, and I was wondering if I needed to get a battery management system (BMS) to keep the batteries going as long as possible. So today, after a pretty long ride where the indicator started to dip into the red, I took off the covers and checked the voltage.

The batteries were labelled:

Electier
Danwant Silicone Power Battery
6-DW-38Ah (12V38Ah)

Before charging, the voltage on all 5 batteries was between 12.58V and 12.61V. During charging, it was from 14.5V to 14.9V. Then about 30 minutes after charging was done, they were between 13.52 and 13.54V. This is very close and within specs, so it looks like the batteries are doing fine and don’t need a BMS, at least for now.

    That is quite good statistics. I hope all works well in the battery area because that is quite crucial in the longevity of any machine’s system.
