[Elecraft] KX2 Battery

[John Cavill]

Because Elecraft would not ship the KX2 battery to New Zealand I made my 
own internal battery packs using 3 * Panasonic 3.4AH 18650 batteries and 
a 3 cell small charging/protection PCB I purchased from Aliexpress. 
Charge voltage is 12.6V with current limiting to 1.6 amps. I placed 
polycarbonate barriers over the terminals then wrapped with wide 
electrical tape. They fit inside the radio nicely.

One of these packs runs the radio for hours. I used the KX2 in the 
middle of winter in a valley in the middle of the Southern Alps a 6 
months ago to radio for a rescue chopper to collect an injured tramper 
instead of triggering beacons we each had. Fantastic radio, hear lots of 
stations in the bush just have trouble some times with the low 
transmitter power output for stations I am working. We were 24Km (2 full 
days walk) and two rugid mountain passes from the nearest road access so 
just had the one battery pack that time. The antenna I take is a 80m 
windom I have made using Kevlar 1mm wire with 55m (180 feet) 1.7mm 
dyneema throw line rope to string across trees etc plus a small 4:1 
balun and 10m of RG316 coax. Total weight is under 700grams (1.5 pounds) 
including bag.  I protect the radio by placing in this water proof/crush 
proof case
