help wanted im building several 10s 36v batteries for my ebike using 80% capacity sanyo batteries from the netherlands and vruzend kit i have 2 questions 1 the batteries vary from 1.80 to 2.1 ah can i put them in any order on the parallel run and 2 watching videos from micah at ebike school.com he mentioned putting two bms on a battery for redundancy but didnt explain how - would i wire them both in identically and if one died would the other seamlessly take over and how would i know one had died and which one had died ?? any advice gratefully received. mike
