Lipo Charger Question

[BrianG]

For what you want, I'd probably go with the MRC 989. Has a built-in PS, so it's a all-in-one package, and will do 4s @ ~7A before hitting the power limit. The 3s is no problem. If you end up getting higher cell count lipos in the future, the 120w power limit will just mean it will take longer to charge the batteries instead of the typical ~1hr.

And the only reason for a built-in balancer IMO is so the charger can read each cell. But I prefer an external balancer so I can remove it during charging if I want. And this lets me use one of those little cell voltage monitors if I want to see the voltage. In summary, I personally wouldn't let the absence of a built-in balancer be a deciding factor, but that's just me...
