Re: [Elecraft] Charging Lithium Ion batteries (KX2) from Car
The filtering is not needed if you're not operating while it's running. :) 73, Jim On 4/15/2018 2:26 PM, Yngvi (TF3Y) wrote: Thanks Jim. I'll take a look at that one.

Thanks Jim. I'll take a look at that one. I wasn't thinking about mobile operating but the KX2 would run directly off the car battery.

Perhaps the folks at Elecraft have a good pointer.I think a mobile charger might be a good addition form some of us. 73, Yngvi TF3Y On Sun, Apr 15, 2018 at 8:18 PM, Jim Brown wrote: > On 4/15/2018 7:04 AM, Yngvi (TF3Y) wrote: > >> Are there recommended chargers for this?

Re: [Elecraft] Charging Lithium Ion batteries (KX2) from Car
For further clarification: The Lithium Ion battery packs supplied by Elecraft are 11.1v, 2.6Ah. I think the Tenergy charger supplied by Elecraft charges at 2000mA 73, Yngvi TF3Y On Sun, Apr 15, 2018 at 2:51 PM, Mike Furrey wrote: > I am not sure what kind (size, shape) of Li batteries are in the KX2 but > as a caver I use 18650 Li batteries in my lights.

Re: [Elecraft] Charging Lithium Ion batteries (KX2) from Car
I am not sure what kind (size, shape) of Li batteries are in the KX2 but as a caver I use 18650 Li batteries in my lights. I have found the Nitecore D4 intelligent charger that works on both 120 VAC and 13 VDC that does a good job of charging a variety of Li and Ni-cad batteries either at home or one the road. 73, Mike WA5POK On Sunday, April 15, 2018 10:06 AM, Yngvi (TF3Y) wrote: Hi folks.

Re: [Elecraft] Charging Lithium Ion batteries (KX2) from Car
You can purchase a small Inverter ( probably least expensive) or Tenergy makes 12VDc powered chargers. -- Sent from: http://elecraft.365791.n2.nabble.com/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
[Elecraft] Charging Lithium Ion batteries (KX2) from Car
Hi folks. Just wondering how you go about charging the Elecraft supplied Lithium Ion batteries for the KX2 from a car (13.8V) supply? Are there recommended chargers for this? The Tenergy charger supplied by Elecraft runs from 100-240V range.
