I see lipos with charge rates of 8C. Okay a 5s 5000mah, that's 40 amps and like 750 watts. Now say you have 6s or 8s...

Who makes a charger with this kind of wattage?

The FMA Cellpro powerlab 8 will charge 1-8 cells at up to 40A, up to a maximum of 1344Watts, its limited to 60A input though so if want to charge the full 8s at 40A you will need a 24V supply from 2 leisure batteries in series or one hell of a powersupply, on 12v it will do 612W which is a 4s pack at 36A.

That is a nice charger. I see they came out with a 10S model but this one almost appears better if you ask me. Can this workstation charger do anything with computer software like watt metering? The one charger I liked that does this is the TME Xtrema, but the output is low for boating packs.

it is better than the cellpro 10, a lot more expensive too, connected to a battery (or 2) it will regeneratively discharge a pack at up to 40A charging your leisure batteries back up,it also has a USB adapther and can plot a discharge graph similar to the CBA graphs you see for cell comparison on the net.

Cool, so the Powerlab it is then. I'm buying one.

I just bought the deal on ebay for the cellpro 8 with extra cables and balance adapter for $222 shipped new in box.

This Powerlab is amazing. I have it running from 2 55ah car batteries in my shop and is just incredible the wattage you can get to multiple packs. Surely the most worthy charger for big batt setups I have ever seen. The software is completely programmable for all of the 25 charging presets you can create. It even recharges the car batts when I do a discharge to check wattage output of a pack.

Thanks I really love this V2.

Why do you charge from batteries in your shop?

Why not just plug the charger into the wall? I can see the issue at the pond though.

This one does 40 amps so I can do 8c on the 5000mah packs.

I charge from batts because of the very high wattage the charger pulls. There is no a/c cord for it. You need between 26 and 32v to get 1344w output. So I could either go buy a powerful d/c supply, or simply wire up two deep cycles which I already have.

Did I read somewhere that I can connect two Powerlabs together in parallel?

There are a bunch of new high-discharge Lipos to hit the market lately that can charge at 10-15C!! I have the one 5600mAH pack that charges at 10C rating.

So now I'm up to a pack requiring 56 amps that I could potentially charge fully in 6 minutes. Can you say "unlimited runtime"? Drive while a pack charges, and have a full pack by the time the first one drains. Packs are cheap enough to do this and not have a care about pack life if it harms them. So now I'm thinking about my second Powerlab 8 to get full potential from these 15C packs. Mwewhahaha
