sorry to sound thick
but never heared the term (oem heat shrink)is this the heatshrink on an individual cell,or the heatshrink which covers the whole pack,which is on preasembled stick packs
would just like to know as im considering sanyo's 3600 competion spec loose cells
reason being,i think the high capacity's 4200 etc... are part of the problem with cell failures.to much for the cells to acomodate
