Portable battery box for QRP operations or drive up SOTA peaks. 🙂
Inspired by a recent article published by Chris VK1CT, I used a $16 plastic ammo box as the container for a 13 volt 8Ah LifePO4 or a 12 volt 9Ah SLA. Both battery types are ideal power supplies for popular QRP amateur radio rigs like the FT817ND.
You may wish to use a smaller capacity battery. There is ample space to accommodate a range of battery dimensions.
The rear single PowerPole pair is for connection to a 20 watt, 1.2 ampere solar panel. The solar panel 18 volt supply is regulated to 14.2 volts by an inline LM317T circuit and connects to the battery via the displayed PowerPole and rocker switch.
The $16.00 plastic box is from Supercheap Auto. 🙂
