Yeah, I can only hope the 4 cell units have a BMS, no info yet.. All I can say at this time is that "they look cool"....

I'll let ya know on the charger, I haz the gearzorz...

As for the cells, I was hoping to top them off via solar, mebbe no luck there, but... I found some flexible cells out of China (*ugh*) and I *might* have a product out of the USA...
