Got back from work today and my 3 year-old cheapo 48v lifepo4 charger wouldn't start charging the battery. It is still putting out 60v. The charging FET on the BMS for my Ping battery melted off the plastic a few weeks ago, but it's not nearly as melted as my friend's whose Pings both did that when he first got them and those have been working for years like that. The BMS is still putting out 52v to the charging connection. Is there a way to determine whether it's the BMS's or the charger's fault that it won't charge? I don't have access to any other 48v batteries or chargers to determine it the easy way, so any help is appreciated. Also any advice for how to potentially get the battery charged in the mean time would be great; this weekend is probably gonna be the warmest weather we'll see for months. So the timing is perfect as usual... why couldn't this have happened in that nasty November we had?
