The connector is referred to as a 'Mate-N-Lok'. I believe it is the same connector that Elecraft uses to plug in the 12v gel cell into the K2's motherboard.
Some people buy a female (receptacle) Mate-N-Lok (from Mouser, etc., use the name as a search term on Mouser's website) and make an adapter to Anderson Powerpoles, a barrel connector, etc., depending on their application. Others cut the connector off the battery and put their own connector on it. It's up to you. I know that one of these cells will fit inside a K1. Has anyone tried to see if it will fit inside a KX1? I also use 'em with my HTs since they are a LOT cheaper than AA NiMH cells and easier to recharge in the field (just plug them into a 12v auto cigarette lighter receptacle -- they can't be overcharged on 13.8 VDC). Two of them fit inside a cheap digital camera case, and it's easy to have a spare pair charging while I use a pair. Like I said, I've got about 40 left so if anyone wants some let me know ASAP. - jgc John Clifford KD7KGX Elecraft K2 #1678 /KSB2/KIO2/KBT2/KAT2/KNB2/KAF2/KPA100 Ten-Tec Omni VI/Opt1, Centaur, 238B Alinco DR-605TQ, DJ-V5 Icom T90A IRLP #3978 email: [EMAIL PROTECTED] _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
