Re: Portable Battery Recommendations

Larry, we enjoy the effort that's put in to benefit the QRP world by all of the organizers and it's all way too much fun even if contacts are minimal.

Thanks for what you do,

I'm lovin' the logo that's in the top of that ammo box!

Just sayin'.

In terms of battery technologies disregarding cost I'd rank them:
1. LiFePO4 (Bioenno, Dakota Lithium)
2. LiPo
3. NiCd
4. Sealed Lead Acid

You can use this calculator to estimate your battery needs:

"Depth of Discharge" is an important factor for run time. Use these values:

LiFePO4 - 90%
LiPo - 80%
NiCd - 75%
SLA - 50%

I have a 3Ah Bioenno LiFePO4 pack that I use with my KX2.

I loved the discussion about Portable Antennas, learned quite a few new ideas to try out.  Now for another.  To power my Ten-Tec Argo IV QRP rig (or a KX2 if I ever get one) out in the field, what kind of light weight battery would you all recommend that could power the rig, running 5 watts, for up to four hours CW and SSB.  I have a sealed Gel-Cell but it's kinda heavy.  Appreciate all your thoughts.  72, Richard AG5M.
