usually the charger notifies you with a chime or beeps. The end voltage should be 4.2v per cell or 8.4v total for 2s lipo.

It depends on what your ESC has its lipo cutoff set at. If it's at 7.2v then I imagine your lipo cutoff is set for 3.6v per cell which is conservative but not a bad thing.

The battery should not have been empty. Instead it should be stored with a storage charge which is why it was at 7.2V. That charger has a setting for storage charge.

Charging at 2 amps is gonna take a long time (couple hrs.) and if the battery was empty, it's probably no good. Shouldn't be drained below 3.0 volts per cell. 6 volts for a 2 cell.

Since your battery is 3200mah you should be balance charging it at 3.2amp. whenever you balance charge you want to do it at 1x the capacity so it you have a 4400mah pack you would charge at 4.4amp and if it's 5000mah you would charge at 5.0amp.

Press the second button from right to see each cell's level. 4.20v = full

You should use a lipo safety bag.

This charger cannot always decide when the battery is fully loaded. The battery can have 4.2/cell, but the charger continues the balancing. Therefore he must check status of each cell instead.

Many chargers allow you to set the capacity of the battery you are charging so you don't over charge it. Check to see if that feature is available.

That specific charger will say "Done" or "Full" where it shows Li2S in the photo and it will show 0.0A right next to the "done"

Do yourself a favour and use a lipo charging safety bag to avoid burning your house down when using cheap chargers and batteries.

Next read the manual for the charger as that'll be a big clue as to what to expect during the charge cycle. As others have said the charger will follow the settings you have selected or its defaults (read the manual) and declare it has finished charging usually at 4.20 v per cell.

Thanks guys for your help.

It beeps when full and also max charge per cell is to be 4.2 as you have mentioned so max 8.4 for 2s battery - 16.8v max for a 14.8v 4s battery etc.

Should the storage charge per cell be about 3.8v?
