I was wondering if anyone has used a 13s BMS for a 12s setup. I’ve seen a few posts with people using a 10s BMS for their 9s setup. The 13s BMS’s are about $14 usd. Whereas the 12s BMS’s are $45 and up.
And here is a link to an equally cheap 12s bms
I’m not recomending this one though. Just the first I found. I do recommend matching your bms with the battery cell count
The charger you posted will not work for 12s Lion or Lipo
It’s a 48v charger designed for lead acid batteries and you need a 50.4v charger for 12S lion/Lipo
Just save money to a decent charger and a decent BMS. Don’t cheap out on stuff that makes a difference. If you get the cheapest things you will still end up buying new things when they break.
