[999zip999]

I've been charging my 2- 12s lifepo4 packs with a meawell HRP 300-24v 10a adjested to 28.6v and a HP 600 dps @ 12.6v @ 47a. for 84v @ 10a or 12amp. Doesn't matter A123 20ah cell @ 40 amp cell can do charging.
So can I series the HP 12.6v that is together with meanwell 28.6 v with the same HP 12.6v and meanwell 28.8v for 84v ?
The HP Are isolated grounds .
What you think ?

If you have an issue with putting the output of power supplies in series, it's likely because the AC ground inside the power supply is shared with the DC ground. I have no idea how common that is. But otherwise you shouldn't have a problem. I routinely use a variable voltage lab power supply to charge individual cells inside packs without any issue.

Here's what I been using a HP 12.6v and a MW 24v set to 28.6v for 41.0v for a 12s lifepo4 and use a second setup for the other 12s.
So 12.6v and 28.6 and combine with the same 12.6v and 28.6v for total of 84v for all 4 units. The 2 -12.6v HP are isolated ground. Thanks as I don't want the smoke out. Thanks.
