What was wrong with your old charger? We could possible fix it. We have fixed quite a few.

Hi, pdove,
I just posted a message in batteries and chargers, explaining my symptoms… I’m having trouble getting hold of Elcon to diagnose an issue. Could you help me? Or perhaps fix or reprogram my charger?
Thanks...

Incidentally, what gave rise to the problem is that I added two cells to a 40 cell pack. Even with 42 cells, the old programming should cover the charging… It’s a 520V algorithm 133-142V in 1V steps. I have drained the battery down below 134V, and I’m trying to charge it to 142, Which is about 3.38V per cell.

3.38 VPC is quite low. You'd really want to go to around 3.55 VPC, which was 142 V for your 40-cell configuration.

Elcon in California could do it (if they are still interested in these older models).

I would love to get it reprogrammed; but as I said, I’m having trouble getting hold of Elcon. I am charging my other cars to about 3.54 per cell. When charging stops, they immediately sag back to about 3.35. So I figured 3.38 was on the low side, but that should be adequate for testing.

If I’m stuck on algorithm seven, then it should start charging at anything below 139 V, shouldn’t it? Historically, I’ve been able to do that with my other cars… Top it back off after I’ve only burned 10 or 20 amp hours.
