I have had good sucess, with the higher maxamps packs (5000 to 8000) I use the 8000 in 2s on my 1/10 electric truck (stadium), because it weighs close to a 6 cell Nimh and goes and goes. I have 2 2s and 2 3s in the 5000 and 8000, and have used them in my Gmaxx G2R and my 1/10 trucks and buggies. I also havePolyquest twenty 2s and 3s 3700's, they're old but still real good (seen 124 amp peak discharge) I also have 2 flightpower 3700 4s 20c, 2 3300 20c and 2 2s 3700 20c and one 4900 20c soft pack (same length as the 3700's, I am impressed with all the packs i got. none have ever failed me

I still see no reason not to use Maxamps. And as far as customer service, I never had to send them a ton of emails for service...EVER! They may not use Enerland cells, but a re good packs to say the least IMO.

The only thing i had a problem with is they do not deliver like they say they should. And also have had puffing of cells for no reason. They are a little cheaper than enerland based packs but id rather pay more for more reliable packs. I have max amps now and actually just noticed slight puffing in another 2s pack. I have been rebuilding them to make other packs so i will not be at a total loss. I have had tp packs for my helis so i know it is not my charger or anything of that nature causing them to puff. I do love maxamps customer service. They have a decent warranty too. Just sucks all my packs are out there warranty. So i am leaning to the Neu or FlightPower Packs now.

You may also consider the new trakpower 3s 5400 packs, retail is listed as 169.99. I have had excellent performance from the 4x 2s 4900 packs I own and have no reason to think the 3s versions would not be of the same quality.

good luck finding them..... the 4900's have a higher discharge rate, wat better than an extra 500ma
