They've got a number of cool batteries on that site .. see the 10V
nominal 56AH pack? looks might small, and at 2%/yr self-discharge it would make a nice emergency battery .. de john/w1rt On 4/20/05, Kevin Rock <[hidden email]> wrote: > For all you folks with Spartan Sprint or field rigs. 5-A continuous > discharge would feed my ATS-3 very well ;) I could put 6 of them is > series-parallel to work for quite a spell. > Kevin KD5ONS > > (I am not affiliated with these folks.

In reply to this post by Kevin Rock
I am always looking at alternative ways to haul my k2/pelican around....
I have been using the internal battery, & tuner qrp 15 watts... However, last trip on a boat, I encountered a guy with a 706 and the small MFJ switcher PS. He DID have AC available,,,, and with questionable band conditions, and when we could operate (ship's facilities available) the choice was easy USE THE POWER. This has me examining how to Pelicanize my portable setup. Maybe I will go with the k2/100 kat100. I loose only the battery, which these little Tadiran Batteries could supply at SMALL SPACE cost.(for qrp op only). I will have the added space requirement for the kat100+MFJ+battpak, less the present small switcher PS for recharging. I think this pile will fit in my current Pelican....I wonder about charging those Tadirans. Am I missing something.... bill he wrote: > 5-A continuous discharge would feed my ATS-3 very well ;) I could put > 6 of them is series-parallel to work for quite a spell. > _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Hi Bill, The battery is only good for 2 watt hours. So six of them does 12 watt hours. If you pull 10 amps at 12 volts for 1 hour, that is 120 watt hours, so the battery will last for 1/10 of an hour. That's 6 minutes of talk time. A couple of things go wrong though - the voltage will drop to 3 x 3.25 volts = 9.75 at 5 A per cell, which is too low I think, but 4 in series will make 16.3 volts open circuit, which is too high I think. 73, AB9GV >This has me examining how to Pelicanize my portable setup. >Maybe I will go with the k2/100 kat100.
