Disco Volante said:Yes, like TORtur3 said the charger should be able to charge other 3s battery using xt60 plugs.
But i would recommend for you to buy a lipo balancer, you can find one from 25 dollars on ebay.
I just bought one imax b6 on ebay (im sure there are other brands and models, its just an example) and i'm waiting for it to arrive, i hope it will give me some peace of mind as i hope it will be better for battery life, making them last longer.
