This question relates to the wiring inside the KX3 and not about battery technology… I did not write the question well.
I have received back a lot of good advice on batteries, all correct and thanks, yet I do want to know about the KX3 wiring if you can help me please. For interest only, the battery I have made is not a LiPo (never used even in my RC gliders, as they do catch fire) it is a lithium Ion. The polymer part refers to it not being an 18650 cell (as used in laptops, power tools and automobiles) but instead the flat 3.7v cells as found in tablets and phones. I may well have used the wrong terminology. Anyway, can anyone help me with the wiring. Can I attach the battery to pins number 1 and 3 of the 10pin P3 connector ? I have asked Elecraft direct and while waiting on their reply thought I would post here. Hope you can help Thanks to all who have responded and 73 Kind Regards, Rob Walker M5REW On 4 Oct 2021, at 18:09, Rob Walker <mail2robertwal...@me.com> wrote: I have made myself a 14.8v lithium ion polymer battery, with battery management system and audible alarm, that fits inside the KX3. Ideally I would like to leave it in the KX3 to charge and charge it by connecting a 15v (max 15.5v) PSU to the DC connector of the KX3. If I connected my battery to pins 1 and 3 of the 10pin P3 connector would this battery power the KX3 and charge when connected to an external 15v PSU…. Without damaging the KX3 of course ?
