Internal battery options for K1 & K2

[Steve Stutman]

LiFePO4 is a good choice, but watch the rail when fully charged.

4S string with some mfrs cells can exceed 15V; don't remember max V for K2.

Simple soln is to use a series diode(s) rated for your max current and with
enough V drop.

If you build your own pack, be sure to use a good BMS.

73,
