[Elecraft] K1 battery recommendations?

[Phil Hystad]

Mike,

I don't have a K1 but I do have a KX1, KX3, and Norcal 40a.  I much prefer Lithium-ion over lead-acid gel cell type.  Although it is more expensive, it is far superior (at least as far as I have found).

I have two 1x4 (four cell) packs from Buddipole with Lithium Iron Phosphate (nano-phosphate) construction from A123 Systems.  This battery provides 13.2 volts (nominal) at 2.3 Ah capacity.  This battery can run a 100 watt transmitter for 30 minutes!  I use one pack at a time so keep one pack in reserve.  This is for portable ops, no hiking, no walking, no bicycling (although, all of that is possible).

I think the current cost is $95 but you do need a LIFEPO4 compatible charger.  

73, phil, K7PEH
