Well Lipo batteries can be externally charged by a balanced Lipo charger ( any RC shop should sell this) . Its also quite troublesome to pull out the batteries as it involves cables. DNA200s also charge at 1A ( and i think only vaporshark and another brand does 2A)
That's why i mentioned most DNA200s have a balanced charger board on board which will balance the 3 cells in the lipo which is pretty safe.
BUT one thing i stress if you do have a DNA200, please set up the battery properly in E-scribe. I know most manufacturers do not set this up by default and you risk damaging your battry if it goes too low. you can also set the charging screen correctly to show the charge percentage and amps being fed to the lipo. for the last few %, it will usually go down to 0.1-0.5 to balance the cells.
Thanks for the tip man! Lipo is a little unfamiliar to me as 18650 is more common but if I wanted to get a dna200 (most of them uses the Lipo) I need to learn more about it man
