plus i cant find anything in the book about volts!!!!!! only amps any help is gd help cheers
A 2s lipo will charge to 8.4v, once it reaches 8.4v it will hold there and continue to charge. Once hitting 8.4v you'll see the charge amps slowly drop as the pack reaches full charge.
Once the charger shows 8.4v the pack is about 90% charged, you can stop the charge process at that point and run it if you wish.
Without more info I'll say use a 1C charge rate. mah capacity / 1000 = X amps
example.....5000mah / 1000 = 5amp charge rate.
