Victron SCC odd behavior, scratching my head

[chrisski]

I've been meaning to get a little 3.7V charger, so I can do a proper cell-by-cell top balance...but, just haven't gotten around to it. So in the meantime, I'm just limiting myself to about 3.4.

What do you have in mind?

I’ve been using a 30 volt 10 amp charger, but would like to see something that can push more amps at a reasonable cost.

THis is what I use:

I think charging 8 of my 280 ah Cells at ten amps on the one I linked above will take between 9 and 10 days, so something with low volts and a bit more amperage would be nice.

Wow that one looks pretty good and for a totally decent price.

Only ones I've found are surprisingly expensive... This is what I thought I'd probably end up getting. I'd charge up the battery pretty far with normal solar charger, like normal each day, then start each cell individually from there - then I only have the last 10-20ah to do on each (otherwise like you said it would take all freaking day at 10A, if you start with dead cells).

I am starting that process tomorrow. The batteries will be hooked 8S to a 15 amp SCC, and should take 2 days to get close and I will move them over to the smaller charger.

I got that off Will’s recommendation on his website. I did return have to return one because something was rattling inside and turned out to be a blown diode.

I’ve topbalanced two smaller battery packs with that and done some electroplating.
