Today’s topic, portable lithium power.
For the ham radio operator in the field, portable battery power needs to be light enough, small enough, modular, have enough capacity, and above all it should be possible to charge with solar power, off grid, and in the field. For the high speed, low drag Amateur Radio Operatorr in the field, we need something a bit more special Thankfully, we can find the answer for this from the lithium battery family.
Most diy builders use 18650 batteries for diy builds. For this build we are going to step it up in performance and ease of build by using the Headway 38120 family of bLiFePO4 calles. These cells are safer to use, and easier to put together in a 12 volt battery pack.
here is the parts list: http://oh8stn.org/blog/2018/06/14/50-60-amp-lifepo4-bms/

Recently my channels supporters helped crowd fund a new Yaesu FT-891 for the solar powered field station. To activate that rig in the field, we needed to build a special power plant, one which would allow us to make use of the rig’s full potential if needed. Enter the 50A current draw, 128ah Headway 38120 based, 10ah LiFePO4 Day Pack for our Yaesu FT-891 Field Radio.
in this video, we build a 50A current draw capable, 128wh LiFePO4 battery pack for the solar powered field station. We augment the pack with our PowerF8lm FM16-7200 Solar Panel, for extended communications
