4S Trakpower or Maxamps for 8XL/MM Combo? - Page 2 - RC-Monster Forums

The reason for people choosing flightpowers over maxamps is that the flightpowers are better in ballance (they are matched) and they deliver a higher voltage on a higher load.

(the maxamps 6K drops bellow 2.8-2.9V on a 1 second 110A load, while the enerland/flightpower 5k packs stay at 3.6V on a 110A load.)

The flightpowers are capable of delivering the current, while the maxamps aren't.

I am curious what the new maxamps 5k cells will do. I would love to see some graphs.

I wonder if the FlightPower/TrakPower/Enerland's are better than 8K's when subjected to 100Amps Constant. The 8K's are rated for 160 constant while the TrakPowers are rated for 100Amps constant.

Logic here would point to the 8K's holding voltage better, no matter how good enerland cells are.

If I recall correctly, the MaxAmps 3K cells are of lower quality than the 4K cells.

The graphs i've seen on 8K packs is that they drop bellow 3.1 V or such on a 120A load. check Promods 50mph with a twinforce thread. so yes, trackpower/enerlands are better in 5K than maxamps 8K.

Wowsers...

I wonder how enerland cells would do in a 2P combination. There'd practically be no voltage drop!

Yes I'm surprised it took so long to come up. I also have some 5000HV copper tab packs coming. One thing I don't understand though. On trakpowers site it says "Fast charge rate 10 Amp (Max 2.5C with balancing charger)". Can the TrakPowers really be charged safely at 10amp? Sounds scary. You have to hand it too them on the hard shell case.

I drive 2P Flightpower packs on one of my Revos, and had a 2P setup on my MBX5 just the other day. Then you see what Brushless motors can really do. They give me the most amazing runtimes too.

Yeah, i was impressed with the runtime Dafni got from his Revo with the 5S2P packs, back at home they only took like 3800mAh IIRC.. if a pack drops under load, it kills the amount of energy.
