first set the right charging current (amps) preferably not exceeding 1s ( if you have 3s 1800mah 15c best to set charge rate to around 0.7 amps ) then hook up your balancing lead to the appropriate balance socket ( 3 cell socket for 3s lipos ), next hook up your lipo charging lead to the charger.
set to lipo balance charge and wait for it to finish charging. DO NOT leave lipos unattended while charging them NO MATTER WHAT.
hope that helps. also b6 chargers have lipo storage function so you can store your lipo at the ideal 80% charge capacity.
just because i don't... doesn't mean i can't.
