Lipo charger for 1/10 racing

[uijui]

Hello,

Been using imax b6ac, but the balancer is shait!

Any suggestions? I want a longtime solution, which can be updated (firmware)....should charge max 3s lipos, 6 amps is ok. Dual channel could be better for me because I drive both 2/4wd....at same day. Internal power 240v is way easier.

Is there this kind of charger? Best if it's made outside of korea, taiwan, china....

Thanks for advise.
