Per-Tore, With increasing cycle count, individual cells are showing differences. If you don't charge them individually, these differences are getting bigger, as reflected by the numbers you posted.
You mentioned that you verified cell capacity using your charger. At what discharge current? Most probably not at the 1.5A which the KX3 draws when transmitting. While powering my KX3 with 8 internal Eneloop cells and varying output power, I found a total internal resistance of 1.15 Ohms. A single Eneloop cell showed 34mOhm (I have an instrument measuring Ri by applying short discharge current pulses). In total, only 25% of the total Ri comes from the 8 cells. Battery holder and wiring are responsible for 75%. 73, Markus HB9BRJ -- View this message in context: http://elecraft.365791.n2.nabble.com/KX3-internal-battery-problems-tp7617201p7617307.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
