Not really an ON LINE Deal but.
Walmart has on Clearance the EVER START Portable Jump Starter Box.
The online info is
http://www.walmart.com/ip/The-Everst...arter/46528407
The Clearance price was $9.00.
I got one and opened it up and it has what looks like a Turnigy 3S 4000 mah and based on there description I think it is a 30C. It also has 10 AWG Silicone wires, balance plug and a set of EC5 plugs. I then got 10 more.
One thing to keep in mind is the EC5 connectors have the metal inserts reversed on the Battery and the Jumper leads and will need to be changed.
Also the balance leads are in the wrong order, (just flip the plastic connector).
Now the other neat things you get:
A very nice set of 10 AWG Silicone leads that are about 1 ft long with very heavy duty battery clamps Just Perfect to make your charger leads for the field.
There is a current limiting and polarity protection pack in the line that I think can be reversed to work properly for the field charger.
The VERY BRIGHT FLASH LIGHT that is in the very useable plastic box can be used for, My first thought, a light for a mini quad or other.
Also there is a balance charger built in the the unit that could easyly be used for small 3S Lipos or overnight trickle charge of big 3S Lipos. PLEASE REVERSE THE PLASTIC SOCKET ON THE CHARGER BOARD
It even comes with a wall wart charger to run it all.
If you do not want to try the Hack of it all, it is a portable car jump starter with flashlight.
Enjoy
