Re: [Elecraft] LiFePO4 Battery Pack Performance
A question: I have an automatic sealed battery charger for my 12V Pb-Ac battery.

Re: [Elecraft] LiFePO4 Battery Pack Performance
This batter seems to have a PCB that prevents overcharging so you may be good with any charger. A good lead acid battery charger should have a cutoff at about 14.5 V, which is good for 12.8V LiFePO4 battery. I found that some chargers actually produce up to 18V but perhaps at a very low current. So it would help to check.

Re: [Elecraft] LiFePO4 Battery Pack Performance
Generally the answer to your question is yes. However I am reminded of the old cartoon where the patient is asking the doctor who is treating his broken arm. 'Doctor when my arm mends will I be able to play the violin?' 'Of course,' the doctor answered. The patient replied, 'Good! I never could play the violin before.' 73 Fred, AE6QL -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Pierre Sent: Friday, August 03, 2012 6:31 AM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] LiFePO4 Battery Pack Performance A question: I have an automatic sealed battery charger for my 12V Pb-Ac battery.

[Elecraft] LiFePO4 Battery Pack Performance
I recently purchased a 4 cell LiFePO4 12.8v 4.5ah battery. I fully charged the battery to 14.4v and then hooked it up to my KX3. Total hours of run time = 21.4 hrs. Settings = backlight off, high power and all the other settings in normal positions. I transmitted in ssb for what would be a normal transmit / receive cycle. I received in ssb and psk 31.
