[Elecraft] KX3 Solar backpacking power advice

[Walter Underwood]

If you don’t mind non-rechargeable batteries, AA lithium primary cells are the lightest option. They are about 0.5 ounce each, so a 3000 mAh set weighs 4 ounces. Carrying a spare set of those will be lighter than a solar panel. They are also 1.5 V, so you get 36 Wh from a set instead of 25 Wh from a set of 2500 mAh NiMh cell.
