Reliable High Discharge Lipos

**Eventorizon** · 22nd May 2012, 15:04

I am looking for a fairly low capacity lipo, say 2500-3500mAh, that can do discharge rates of about 240A. (So for a 2500mAh battery it would need to do 100C, or a 3500mAh would need 70C). As you know there are loads of lipo brands out there but which are reliable, safe and long lasting.

The ones I have seen have been...
VoltON
Desire Power
Turnigy
Venom
Thunderpower
Poweredge

What experience or rumours have people heard about these different lipo brands. I am currently using Gens Ace lipos but they dont seem to do a Lipo with a low capacity that does a high enough discharge rate.

Note: I know its a little mad but I don't want to give away the details if this new design turns out to be viable! :wink:

I'm sure you have your reasons, but why not just up the capacity? Would be the easiest solution.

I use FlightPower Li-Pos, seem pretty popular.

Its partially to do with size; bigger capacity, bigger battery, and you end up with left over power. I ran 4 fights at GSL on my 4000mAh drive battery without recharging. I recharged after the 1st fight but the charger could only put 600mAh back into the battery. (well I was only in the area for 1.5 mins not 3)

Theoretically the bigger capacity you have, then the larger continuous current you can deliver for a lower C rating.

Helpfully the Flightpower website has Continous and Burst ratings for all it's batteries do you don't have to do the maths.

An alternative would be to have 2 batteries running in parallel, gives you more options for space. But what on earth do you want with 240a!?

240amp 3.5amp that won't last a fight will it?
I also found this http://www.giantshark.co.uk/gens-5000ma ... 06494.html
which is expensive

what do you need 250 amps for and at what voltage?

I need a 4 cell, 14.8V, though the motors nominal is 12V...

The motors pull just under 20A at their most efficient, but with the loading they will be under I doubt I will get anywhere near that...

I have found a 4 Cell 4000mAh 50C on the Gens Ace site but its germany only for some reason...

This is still just an idea, it may not even work but hey, we like to set ourselves a challenge!
