You must use a lithium-specific charger. There is no "threshold" or any such nickel-cell stuff. :) The lipo chargers know what to do.. they charge to a specific voltage (4.20 volts per cell typically) and hold the voltage steady and slowly drop the amps down to zero.

Yes... you can charge at 1c... which is 8 amps for the 8000mah (8 amp-hour) packs.

Yes... you can put the packs on the charger right after the run... never discharge the lipo before charging under normal operation.

Definitely get up to speed on the lipos.... it's a different ballgame than nimhs.

EDIT: aahhrr beat to the punch again. too many fast guys here :)

So are you saying use an Astroflight 109(i think that was it) instead of my ICE?

I wouldn't use the Astroflight. It's not a CC/CV charger and doesn't work well with most balancers. Get something like the E-station 701 or even a 301. I think the 301 is the same thing as a Multiplex charge, like alot of other chargers. The Ice should work though...

Sorry to hijack again, but for the noobs, what is a CC/CV charger?

ICE is fine... it is a true "lithium" charger. I meant you can't just use any old battery charger.

CC/CV is "constant current/constant voltage" and it describes how it charges the battery.

CC stage gets the battery to 4.2v
CV tops off the charge by holding it steady at 4.2 until the battery can't take it any more.

The current will slowly drop to zero once the charger hits 4.2 and switches to CV mode. . Once the current drops off a lot, like below 1 amp... there isn't much "charge" put into the battery... just a few mah.

Hey Serum with a couple of Mike's sinks and a bit of welding you can have one that you could beat a whale to death with :032:

Holy hell...That thing is nice! Besides that, I'm sure you won't have a problem with over heating...

Yeah i just read through the ICE's manual...its should actually be a pretty good lipo charger.

Now i just need a motor mount to actually continue with this project. I found a member on RCCA that has made a machined aluminum mount that im trying to see if he can make me one. And i also emailed Mike about it but i will have to wait for him to return before i get an answer. Until then there isnt too much i can do to the truggy except to sit and wait.

Cool(ing) thing Cab!

TIG welded?

That motor mount is crazy :eek: Looks very strong.....

James, The waiting is something I never get used too with this hobby :027:
I'm sure Mike will sort something for you though.

Serum , Na its Oxy'/'cetelene, with a fine tip and a VERY practiced hand.
Its abit heavier than I would have liked but mabye a few hole here and there will sort that. Still it wont be bending anytime soon
