Another charging question - ERIC

Sergio

Definitely send them the log, the data does not look right, You are returning on average less than a 3AH rate everytime you charge.

It looks like there is at least one bad battery that is raising the voltage during charge but not allowing enough current to actually charge the entire pack.

Thanks Sergio.

Is there a good way for me to check the batteries - or do i just need to have them load tested individually?

I know in the past I have checked the voltage individually and they were always within .1 of a volt of each other. I'll check again tonight.

How do you get the idat software, and what is the proceeduer to go thru to use it?

I looked on their website, and it says something about getting a zip file from your oem distributor?/

Thank you Sergio

The best thing to do is to measure each individual battery when the charging voltage first gets above 60v.

That will show you how the total voltage is being distributed to the batteries, I suspect one of them is going to be a lot higher than the others.

Good news - On the charge cycle last night it only ran about 2-3 hours and shut off when completed!

Not sure if the previous night's charge was some kind of a calibration/learning cycle or just a fluke. Will keep an eye on it for the next few days, but for now this seems very promising.

BTW, I checked the batteries individually before and after. They're all reading the same exact voltage.
