2s lipo final voltage advice
 

Hi guys. Charged my 2s lipos for the first time to do some testing. I was told the brca voltage limit is 8.4v for touring cars so manually stopped it there. My charger was still going when I stopped it. Have I done the right thing??

lipo max voltage are 8.44v

Pending on your charger, you can set your end voltage when charging.
Check your charger manual.

The electronics know best, but there's nothing wrong with stopping the charge early if you need to for whatever reason - i.e. to make the start of a heat etc.

It's not like the good old days of Nicads or Nimhs where you'd nuke the s##t out of them for maximum punch... the performance difference is negligible in the upper voltages for Lipo cells, and certainly not worth the risk of detonation :)

Make sure your charger is set for Lipo chemistry & balance charge whenever possible.

The Chargers all set for lipo etc. Just expected it to stop at 8.4v. Will have a look at setting the finish voltage. I'll put it down to experience. Cheers.

it will get to 8.4 volts and stay there then your amps will drop, lipo are charged at cv not cc (constantvoltage) (constant current)

As Mark says, lipos charge differently to nimh. The charger will put power into the battery at whatever current it is set at, until it reads 8.4v from the battery. The battery will be 2/3 to 3/4 full at this point. To finish the charge the charger then slows down the current to maintain the battery at 8.4v until the charger can't get any more energy into the battery without it going over voltage. It then cuts off.
