Be aware that the polyfuse is a thermal device and reacts rather slowly. LiPo/LiFePO4 batteries are VERY low impedance and can put out hundreds of amps into a short circuit. That can easily exceed the ratings of standard polyfuses. Those designed for battery service, like the VT series, are somewhat more robust but can be physically larger. Personally I rely on standard ATC fuses in series with the power leads. 73, Bob, WB4SON On Tue, Aug 13, 2013 at 2:43 PM, KD0GLS <[email protected]> wrote: > Wondering if anyone here has made use of a polyfuse between an external > SLA battery and a KX3.
