Re: First Time Charge
I believe that more than a .05 difference in cells on the same battery says it is bad. Battery 3 & 6 have that. Can someone else confirm this?

Re: First Time Charge
The batteries look better than I thought they would, honestly. After 12 hours they show good voltage and specific gravity. Some cells do raise concern but but all in all you have 90% of a full reading part of which is due to 55 degrees. I think a load test is in order... can you drive it for 15 minutes straight and let it set for 15 minutes and give us another voltage reading for each battery?

Re: First Time Charge
I was reading around the site and wonder if I need to have the batteries disconnected for all these test/readings?

Looking forward to you voltage readings after 15 minutes of use. If they hold up for that test then you can make longer runs and test again but putting on the charger after each test and leaving it there until it shuts off itself. scottyb pointed that out to me and it was amazing how much longer it kept conditioning the batteries after it got down to like 1-2 amps of output the next time I recharged. When just parked go at least once a week and unplug and replug in the charge AC cord so it will again top them off. |

Re: First Time Charge
After running it for 15 min straight and letting it sit for 15 min. The battery indicator is just above half. We used be about to run this hard for more than an hour.
Here are the readings: Pack 37.0v #1 6.2v #2 6.2v #3 6.0v #4 6.1v #5 6.0v #6 6.1v |
