My used charger went pop yesterday. I had spent the day before balancing some batteries and had cycled the charger perhaps 5-6 times during the day.

Yesterday I took a test drive and then plugged in to charge, it was on for maybe 5 mins and then a loud pop.

I haven't investigated anything yet but I'm going to bet it's a rectifier or other solid state switching component that gloriously reached the end of its service life after being stressed too much.

Has anyone had any luck getting parts and repairing these or am I up a creek? Thanks.

Thanks John, any help would be great.
Quick update, I poked around and couldn't find any obvious signs of damage (like blown up fets or black marks)
so I thought screw it, and plugged it in to charge.
Turns out only half the charger is dead (probably the side that isn't directly cooled with fans lol :/) it started charging and pumping 1250watts into the pack. (of course the peak was ~2700 before)

so I'm not 100% up a creek, but my paddle has a good crack in it...

Could be a cap. Sometimes it’s not obvious. I’ve seen a lot of bridge rectifiers blow as well. It’s under the silver clips.
