Best battery for a 4wd sct?

I keep having problems with my negative lead melting off and tonight the case of the battery melted down. So since I'm going to have to buy a new battery what does everyone suggest? I would like for it to be able to run 10-12 minutes comfortably. I'm currently running a tekin rx8 with a pro 4 4300hd in a tekno sct410.

I've had SMC and SPC batteries, liked them both.
IMO, you don't need anything over 6000mAh. I run a 6500mAh 65c battery and I'm only using about 3500mAh to run a 8 minute race (4.5t 550 Novak, 30-32 sec lap time). But that's my truck on my local track... So take it with a grain of salt.

SMC and IP packs are almost the same, the IP's have a slightly lower IR (probably not noticeable) but the resistance goes up faster over the life of the pack, so the SMC's will last longer. In a pro4, you won't notice the slightly lower IR that the IP's have to offer (you might notice in 17.5 classes if you're pro)

Also, make certain you have the truck geared properly. If you are running too big a pinion, you can overheat things quickly. However your description does sound more like a batt connection. Did you have low voltage cut off set on the Tekin? It would seem it would have detected voltage drop off as the batt melted down.

Thunderpower all the way for me. Ill throw the 65c g4 pro race against 100c batts and the punch stays consistent throughout the pack. I ran the thunderpower's against the Orion 90c carbon's in an e buggy and the thunderpower's smoked them. I have not tried the uber spendy revtech's but I hear good things about them

For the solder to melt and fail there had to be a problem. The battery could of been it but it could also be a poor connector that was not tight enough or had poor surface area contact. It could also be a poor (cold) solder connection. All these will increase the resistance and that will make heat. Make shure that these are all good so you will not melt down your new battery.
if you do not use the right silver solder or if you use bad connections, people can advise the most expensive and biggest lipo's there are, but it aint gonna solve things.
first look at your solder connections
