I suspect that no matter what type of batteries that you have, they would die as soon as you press the transmit button. Pen cell batteries are not designed for the current required to transmit.
As for your cells, they are probably either NiCad or NiMH cells. They can be charged with the same "smart charger". Trickle charging them is not a good idea. You need the charger to turn off when the cells are fully charged. You certainly can connect the cells in series to get a higher voltage. Connecting this type cells in parallel without diodes to protect one set from discharging into the other is not generally recommended. I put batteries & radio control into garden railroad trains and I never connect 2 battery packs in parallel without diodes. If you really want to run your radio from batteries, either get some gell-cells batteries or a set of good, high current NiCad, NiMH or litium batteries. I have bought NiMH D cells with a rating of 10A/H. They will deliver over 30 amps. Your pen cells are probably 2A/H and will only do that at low currents since their internal resistance is relatively high. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
