Good advice - I picked up a small LiPo Battery Bag from Amazon. -- View this message in context: http://elecraft.365791.n2.nabble.com/KX2-KXBT2-Charger-tp7617624p7620897.html Sent from the Elecraft mailing list archive at Nabble.com.

Re: [Elecraft] [ KX2] KXBT2 Charger

One of the main failure modes of Li-Ion batteries is trying to charge a defective battery ( puffed pack). When Li-Ion batteries begin to fail one or more cells develop a high internal resistance and heat up during charging. The 2hr warning is likely driven by the danger of trying to charge a bad

Re: [Elecraft] [ KX2] KXBT2 Charger

I put a battery in a steel pan out on the concrete patio and charged overnight - the LED went Red to Green overnight and the battery was still cool in the morning, so all went well. The timer sounds like a good solution for indoor safe charging, but I'll still do so in a pan on a patio block,

Re: [Elecraft] [ KX2] KXBT2 Charger

Hi Bill: One slick trick I’ve done with chargers is to use one of those timer switches… the type often used to turn on and off interior lighting, to make it appear that someone is home, when they are not home. The model I have uses some plastic pins, color coded, to set the “on” time,

Re: [Elecraft] [ KX2] KXBT2 Charger

I would get a timer switch, set it for the recommended charging time. and run the charger off that switch. If you get back before it starts charging again, all should be well. 73 Bill AE6JV On 7/29/16 at 5:02 PM, donw...@embarqmail.com (Don Wilhelm) wrote: If you wish to charge them

Interesting question. In just received my kx2 today. I ordered everything EXEPT the kxbt2! I don't know how I missed that so I'm ordering it this weekend. Can't wait to get on the air with it Ronnie w5sum MaverickNH wrote: >"Do not continue charging the battery if it

Re: [Elecraft] [ KX2] KXBT2 Charger

Yes, with Lithium batteries, follow the instructions. If they do not recharge within the specified time, something is wrong. Whether that specified charging time is 2 hours, or something else is of no consequence. If it does not charge within the specified time, it is cause for investigation

Re: [Elecraft] [ KX2] KXBT2 Charger

"Do not continue charging the battery if it does not recharge within the specified charging time. Doing so may cause the battery to become hot, rupture, or ignite." Does this mean the battery should not be charged more than ~2hr to full charge? So it shouldn't be charged overnight? -- View

Re: [Elecraft] [ KX2] KXBT2 Charger

There may be DC chargers that are compatible with the KX2's battery pack. We're looking at a few. Until then I highly recommend using our inexpensive fast charger, which is designed specifically for this application, with all required monitoring and control circuitry to ensure safe operation.

Re: [Elecraft] [ KX2] KXBT2 Charger

I charged my Li-ion batteries by a voltage regulator LM317 set to 12.6V. Never a problem and the battery lasted but the regulator needs a sink. It would be really convenient to be able to charge (even slower) without removing the battery. It would really be nice to add internal Li-Ion option to

Re: [Elecraft] [ KX2] KXBT2 Charger

I feel kind of stupid buying a charger when I have a very expensive bench power supply. Does that battery pack have a balancing circuit and over voltage protection? On Thu, May 19, 2016 at 11:54 AM, Jerry Moore wrote: > KXBT2 Charger: Can the charger be connected to a

KXBT2 Charger: Can the charger be connected to a DC power source without an inverter to charge the KXBT2 Li-Ion battery pack? Considering the intended POU is pedestrian I can see a great need/use for solar to power the charger/recharge the battery pack. Depending upon circuit design it should be
