I would like to suggest this. Purchase the regular started with alligator clips, no attachable battery pack. Build you a small wooden box, then purchase the closed Gel Cell battery, these battery's last forever, at the price of around $12 you can't go wrong. I have also seen others use a motor cycle batteries to power these starters.

What I did was purchase just the wooden field box kit and built it. I used copper gurney's the ones that electricians use, drilled holes through the wood and then secured the gurneys with copper nuts that came with the gurney clamp. I then also mounted banana plugs on the lower portion of the box for anything that I had with banana plugs. The cost of the field battery and charger is around $24 give or take.


Edit in

Forgot to mention that I used I believe 10 gage wire from the batter post to the gurney's and then from the gurney ran another jumper down to the banana plugs.
