Lwiddish,
Not just a crack. Look at the information on the battery management system. It spells out exactly what it is going to do.
From the series statement, I infer that LI. when connected in parallel, need to follow balanced battery wiring guidelines, and should be fully charged individually before doing so.
They are the first "drop ins" I've seen that rival the price SiO2.
They sell in 26 countries including USA and Canada.
I've emailed them about resetting the bms.
