[Elecraft] KX3 Suggested External Battery

[Walter Underwood]

Maybe. The batteries in the boxes are kinda heavy.

For a shorter trip, non-rechargeable lithium AA batteries are great. They are very light, about half the weight of NiMH batteries. At 1.5 V, 3000 mAh, and 0.5 ounces per battery, they have great energy density. A bit pricey, but you could buy a lot of them for the cost of one LiFePO4 pack. Eight batteries are only four ounces. A similar Bienno  battery is 0.9 pounds (14+ ounces). You could carry 9 Ah of non-rechargeable AA’s for less weight (12 oz.) than 3 Ah of rechargeable LiFePO4.
