So I need to purchase a battery charger to charge up a 3S 2200mah battery for the steady grip hack. I figured I should get a charger that could charge the H batteries as well once a dock is made. I was considering this one Quattro 4x6S Lithium Polymer Multi Charger HobbyKing™ Quattro 4x6S Lithium Polymer Multi Charger Do you think this is a good option? What would you suggest otherwise? Thanks Haydn It is 50w / channel. So I guess around 3.2A.
