a good idea if you want to make a quick change multitool table is to head to your local hobby shop and pick up some battery phugs/sockets and some wire. Bypass the original switch with a socket/plug on the positive or negative, and insert a 250v reccomended switch somewhere on the table with a socket/plug opposite to that of whats on your tool. When your tool is mounted on the table, use the trigger lock feature most tools have(to keep it on) so you only have one switch to turn it on and off at will. If you're worried about usability after such a mod, just make a loop jumper to continue the circuit and use the drill like normal
Well your basic all round rc battery is an 11.1v lipo. Considering you already have your basic 12 v rating(virtually all 12v rated appliances CD s can run on this) you can simply connect as many as the needed nap hour in parallel (red-red, black-black) . The best bit is that lipos are now relatively inexpensive, and you can get balancing board adapters to leave to let you charge 8 batteries at once. Silly pull the lot out with them all still connected in parallel and hook up the balance leads and presto, give it a few hours and you have a 16000mah(or 16ah) battery pack. While this does take a few extra man minutes when your in the process of charging etc, the lack of cost and effective efficiency would more than make up for it. Worst case scenario, rig up a solar lipo charger to get all your batteries charged on the go. If I had the funds and the tools I would definitely give this a go but it's difficult to come by funds where I live
I think this would go great with 18650's chainlinked and parrelel link, you can source a much higher mAh and still have plenty of room to spare. The only downside would be finding a li-ion charging board capable of charging so many batteries at any one given time, but it could also be made modular with replaceable battery packs, or even use rc li-po's in parralel to gain the desired Amp-Hour, with the benefits of rapid charging and high performance!
