I was wondering if anyone has a recommendation on an AC charger for a 14s NMC battery pack? The full charge voltage of such a bank is 4.2V per sell or 58.8V. I'm just looking for something cheap that I can use in my Youtube videos for building and testing various battery packs. Something like 10A or so should be fine. Everything I see online is either 1A, 2A, or $300...

Right now, the only way I can charge a 14s battery is to take one of my solar arrays offline and hook it up to the PCM60X temporarily, which is rather intrusive, or use an MPT-7210A converter (which are really no good). I suppose I could invest in an MPP Solar charger inverter but that's a lot of money just to test batteries.

I bought 3 of these YZPOWER 58.8v 15a (750watt range) on ebay last year. I don't see them on ebay right now but here they are on aliexpress - https://www.aliexpress.com/item/328...7U_Fx27hooSNkJIbCqBoC174QAvD_BwE&gclsrc=aw.ds You can choose 10a thru 15a sizes.

I use them with my home generator to charge my DIY powerwall when I test run the generator. Have used them aprox 20hrs (2hrs once a month over the last year)... so not a lot but they seem solid and you can even adjust the voltage a bit if you wish.

Why not use an off the shelf 60v ac/dc power supply and just tweak the trim potentiometer down slightly? There is a 600W (10A) unit on Ebay for less than $40.
