There are tons of Lipo chargers out there to choose from .. (and all of them blow the stock Phantom charger out of the water).
depends on how much money you want to spend,. and if you want to balance charge many different ones at the same time.
I went with the most economical route tho
- I bought the Accucel 6
-with a 50w power supply
-and a parallel charging board (so I can charge multiple batteries at a time.
-and picked up lipo battery checker
all from the online USA warehouse of Hobbyking.com.
if you want to go the high route, Hitek makes some great chargers
