ok so marrying batteries... I know that this is important, but say I have 2 batteries bought and initially charged at different times... However, I did not discharge either of them yet... can they be married? or is this unsafe? LG Hg2 batteries... like can I discharge them together for the first time even though they weren't charged together initially... and then keep them married after the initial discharge... hope this makes sense 
also, I don't remember if I charged them (initially) at the same amp :/
