Sure, they had to idiotproof it all. But, a 14s capable balance charger, with 80,90,100% charge, would have our batteries last up to four times longer.
Instead, we have to go WAY past charge, to do any balance at all. And even then, that only works on healthy battery. New and equal cells.
If it was a 240v plug I think it could be plug in. And it would be VERIFIED as working. It could be just as safe as a bms, if folks were diligentish.
Instead, we have to haul the bms along for the ride.
I have scoured the internet, looking for a solution, there is none. Unless you go chargery, or cellpro. Or Icharger, at mega dollars.
If it is simply lack of interest, then build it and they will come.
What say you?
