Need a lipo charger

[Rok Krawl]

Ok so I do have the dynamite passport lipo charger that I use to charge all my plane, car, and now boat batteries.
Its a pain to charge one battery at a time for the boat, so before I run out and buy a 2nd charger, any one use or know of a good dual battery charger?
I have heard rumors that the chargers that can charge multiple batteries cant take the abuse over time and die quickly.

Can anyone shed a little light on this?

And on a 2nd note, whats the minimal C rating a pack should have for a boat? Currently running motley crew. I need to order a few sets of packs.
I don't want to get the bare minimal C rating and have one puff up on me. I guess a 30C is optimal?
Thanks for the help.

Hyperion Duo chargers are excellent. They have 2 independent output circuilts and ports (but can also "synch" balance them if you are running the packs in series), so it is bascially 2 actual chargers in one. I've recently purchased 2 parallel chargring boards, one for each output, and am charging 4 packs at once at full power. The "store" and "discharge" features are very handy.

I have the 0615i duo

But there is a newer model available, steve sells them here at OSE

These chargers are pricey, but I have not regretted it one day-- my boat collection quickly grew and between my son and I we have 12 packs to charge for an outing... plus I use this charger for my helicopter packs as well. If you want to run these chargers on AC power then you need a high power AC supply.

Hitec now has a duel charger but lipos are limited to 1C charge rate.
