Found this,
The Triton Jr has the same specs, but the board is a different design.

Ahh ok thanks. So I can just charge my Lipo pretty much after I run it for even 5mins if I wanted to?

Because I think someone said its bad to top off your Lipo, but I think he doesnt know what hes on about.

Also if I dont ever charge it to its full capacity (3200) how would I check that it has been fully charged if I say start charging them at 30% capacity, 40% capacity etc? by reading the voltage?

Oh and I was also considering getting the Avionics charger, but instead got the ICE, the avionics would of costed me roughly 125, and for $25 extra I got the ICE instead, you guys reckon that was a better move?

Thanks.
Don't worry, trust the Novak smart stop. I believe the cutoff on that is pretty conservative.

Your charger should do constant current until it reaches 8.40V for a 2 cell pack. Then it switches over to constant voltage and holds voltage at 8.40V while reducing the current. Once the current drops to 1/20C, then then charge is usually stopped. When the charger switches from Constant Current to Constant Voltage, the battery is already 90-95% charged.

yeah, it's acutually much healthier to keep topping off your lipo than to run it all the way down.

In all fairness if you want to stay ahead of the future, buy a charger that will charge at 10 amps.
The future of lipos will more than likely grow and as it does the MAh's will to and you will need a charger that will charge them at a higher rate.
So as the times change. So will chargers.
Even my ICE will be obsolete some day and it charges at 4.8 amps.
That is for lipos the highest I can charge is 4.8 amps.

So the ICE only charges lipo's to 4.8A MAX ?

MaxAmps already has a 12,000 mAh pack available. What's out there currently to charge something like that at 1C? At 2C, that's a 24A charge rate, right? Man, we're gonna need bigger power supplies eventually.

I'm 99.8% sure you can go to just as high a current with a LiPo as you can with NIMH...you have to select the charge rate to begin with, so just set it higher.

Thats all I can get mine to crank out.
I'm charging platinum 4800's right now so I should be set for a while.
But I plan to jump into some higher MAH's this next winter.
The higher MAH's are over rated if your running stock.
You only need the higher MAH's to make run time with hotter motors.
It will charge at higher rates on sub-c.
Lots of advantages to the higher MAH's. When it comes to longevity.
You will be able to run 20% of the packs charge in a five minute race.
Unless they start running 10 minute mains with the packs of the future you will be able to make them last forever.
(If you use the charge and repeak with out running more than 1 round at a time before repeaking them.) Its the best method of use for lipos.
I will double check the charge rate on my ICE for Lipos.

Well I just found a new respect for my ICE and the future of it.
All you have to do when you set the Lipo MAH's is set it to the MAH's of that pack and it automatically sets the peak voltage that you can charge it at 1c Cool.
I wont need a new charger ever.

I've been charging at that setting so long I just never even experimented. I bought it for lipos set it and haven't looked back.
I'm glad I checked it.
Bring on the 6000's now.
All this talk of chargers today got me thinking and looking at the future as far as lipos are concerned. And what charger would I really recommend in order to stay ahead of the game.

Eventually we will be charging at higher and higher currents but I think I will get my moneys worth out of my ICE long before that happens! Even if the capacities we need don't increase by 3 folds (we don't need 10amp cells for racing anytime soon, flying maybe... ) I can see cells that take a higher charge rate in the very near future so higher charge rate is definately a bonus. But still, the same cells will charge just FINE on lower C. No need to worry!

If you want to take better care of your packs, the slower lower rate will be a plus. As long as you have 2 packs it wont matter how long it takes to charge.
I have 2 packs and repeak each one in between rounds and it works out great.
That is as long as its not discharged more than a round at a time.

I'm thinking about getting a 2nd pack, might get another 3200 since they've been good to me, but I'm also considering the 6000 maxamps pack, what do you reckon?
