If you're able to solder, I would order deans plugs and wire from HK and make all your connectors the same so that you don't have to use different adaptors. Eg. All batteries have female deans ends. All esc have male deans ends.
its ok to say change to all the same connectors but a few adaptors of each combination is less soldering than having to change and solder whenever you get something new, but i do understand some people find this messy.
Purchased this battery for my Tamiya MAN TGX 26.540 6x4 XLX tractor truck. Fits ok with a bit of dremel work to the trucks battery tray. Running RC4wd 65 turn motor. Truck has heaps of torque, grunt machine, will haul my box of Coopers Pale Ale:) Took 2 days to arrive from AU wharehouse to my door. Thanks Hobbyking:)
