Red Wine Audio - 30.2 LFP-V

LiFe batteries are common in Radio Control.   These super powerful batteries are the type used in "Battlebots" and large scale model planes.

Hopefully these guys have the same mA rating , capacity , and connector you need.  

It seems they are not available anymore.

This thread may help.

You might get lucky and they used a common connector like XT90 or EC5.     These connections can handle high current and are often used on Lithium Polymer batteries.   I hope you can find one that is plug and play.   

Thanks for the information, most appreciated!

If I figure this out I will post back.

I'm going to have to spend some time with pen & paper to write out how this will work.
