been away for a while. Lipo's not taken care of..??

Same here- British weather doesnt permit much regular use.

I would just chuck them on the charger, check the cell voltages to make sure they arent massively out of whack, then just do a normal balance charge to 4.2v per cell, then use 'em or stick 'em back on the shelf ( I dont bother with the 'storage charge' setting ).

lipo batteries should be stored at about 3,8 v or a bit higher, but not fully charged for longer time. the higher voltage stresses the cells. that's why they ship new lipos with about 3,8 v (each cell). you can store the batteries at 4,2 for a week or two, but not for months. that's bad for the performance.
