Superemaxx89, here is a link to a LVC device you can use:
http://www.dimensionengineering.com/LipoShield.htm You only need one of these, but it will need to be hooked up to the total voltage from both 3s packs (you could hook it up to the input wires on the controller).
To be honest with you, I think you are spending way too much money on batteries. If you have a mishap, that could mean $250+ gone. What I would suggest is getting 4 3s 4000mah packs, and only using 2 at a time (in series). The 4000mah cells can handle the amp draw just fine in 1p, and when they run down you could just switch them with the other 2 packs. Overall, I think this would be the best setup if you are still looking to spend a lot of money.
I got Team Orion platinum li-po now and I spent $120 on the maxxamps pack.

thats great, make your own thread!:035:

Does maxamps have any sort of return policy?

What taps do you recommend?

MetalMan 02.05.2006 08:46 PM
Maxamps has very good customer service, undoubtedly one of the best out there.

If you're going to be using the Hyperion LBA6 balancer, then you can get the Hyperion balancing taps.

As far as 48amps goes, that is the continuous rating. Your truck will only require ~23amps average, but will pull more in bursts. These cells are rated at 64amps burst for 10 sec., and can handle even more in shorter bursts (spikes). In 1p they will be plenty, especially since you're using a pretty high voltage setup.

If thats true, then why are emaxx controllers rated for 97+ amps?

squeeforever 02.05.2006 11:36 PM
good question. to be honest i have no clue:032: :007:

boss 302 02.05.2006 11:55 PM
same here no idea :032:
i would like to know the exact reason myself

Superemaxx89 02.06.2006 12:01 AM
maybe we have been getting ripped off...:013:

MetalMan 02.06.2006 12:16 AM
It's for the high burst capability, as well as for heat issues. The MOSFETs used in the controllers are rated for a LOT of amps, but that's at 25 degrees C. At their rated number of amps, they are going to get hot, which is why heatsinks are used, but they will still heat up, making them less capable of handling as many amps as they are rated for.

WHERE DO YOU GET ALL THIS INFO!!!!!:confused:

MetalMan 02.06.2006 12:25 AM
I've read several datasheets on some MOSFETS, and picked up various info. It's all about the time ;).
