I have two NIP Tekin 3400 2s 23c 2c charge rate batteries.
These are great batteries i bought 4 of them and found that they run a lot longer then expected, so i am selling the 2 new ones.
I run the other 2 in a SC10 with RS 10.5 geared 87/20 on offroad carpet track, and i get two 5 min heats out of the first one (with plenty left over) and then throw in the second battery for the main. With my MaxAmps they would be all hot and puffy after running like this. You can charge these at 7 amps , which takes about 10-15 mins. Hard cased for durability and ROAR legal
Here is the retail price and specs -
