Re: [Elecraft] Charger question

2021-10-06 Thread Howard Zehr

There is a a discussion on the Elecraft .io forum where a popular power supply 
manufacturer describes the difference between a Power Suppy and Charger.  The 
manufacturer pointed out that using a power supply to charge lithium batteries 
is risky, because current is usually not regulated and voltage regulation might 
not be tight enough.
 
As an engineer friend reminded me, charging lithium battery banks requires 
tight contrrol of both voltage and current. The 14.8V lipo pack that was 
discussed would normally be charged with 16.8V (4 x 4.2V) at 500ma to 2A, 
depending on the battery manufacturere specifications.

As an option, and an Radio Control (RC) plane flier:

I use the Hobby Grade Smart Chargers that can handle the actual battery
chemistry for the KX2 on mine.

For less money than the ProAudio charger I get a very Smart Charger and can
handle many chemistries.

Ones like this plug directly in the wall and some even have bluetooth to
monitor your charge rates.  They are only $50.

I THIRD the motion! I have one too for my KX3/PX3. I don't use it much now
because I got the KXPA100, and a power supply to go with it, and it had
extra Powerpole sockets, so I just run the radio off the amp's power supply
now. But I got that Pro Audio power supply because of the low noise.

For external battery, Talentcell has an 8300mAh @ 12v battery pack that has
a 6A max output. I can run both the KX3 and the PX3 and transmit full power
(without the amp) and that battery takes it no problem. Got it on Amazon.
(They also have an 11000mAh pack that gives 6A at 12v as well.)

2019-07-29 Thread Don Wilhelm

Mark,

Are you really looking for a charger, or do you want a power supply?
If a power supply, take a look at the PAE Kx33 from Pro Audio 
Engineering (do a Google search).


If you really want a charger, use what is recommended by the supplier of 
the battery that you wish to use.


73,
Don W3FPR

Re: [Elecraft] Charger problem: ERR BC3 in VFO B, d=002 in VFO A

2013-07-30 Thread WA7OP
Works as expected now! This is problem is now resolved by a more serious
reseating of the KXBC3 board (as is suggested in the manual). Also, kit
builders should take care with the wire routing. 
Elecraft has certainly got a jewel here. They rock! And, many thanks to
Rich, AC7, for responding.

[Elecraft] Charger problem: ERR BC3 in VFO B, d=002 in VFO A

2013-07-29 Thread WA7OP
I was using Lithiums and when they died I installed fresh NiMH and then
worked the Baltic on 5 watts. Then I enabled the charger for 8 hours. The
next day the charge setting in the menu displays ERR BC3 in VFO B, d=002 in
VFO A. This locks the display with those messages until the KX3 is power
cycled.The  FW is v1.5. The NiMH cells are not charging. Also the clock
won't set and displays 45:85:85. I found the ERR BC3 was encountered by some
one else running older FW but there was no definitive resolution. Can anyone
provide some ideas for a solution?

Tnx, Scott wa7op
