I needed a way to carry my FTM-400 around including a battery and I stumbled across some other projects that used empty ammo crates as cases for their radios.
My adaption of this concept has the following features:
- 12V motorcycle battery
- Panel Mount for Anderson Power Poles
- Panel Mount with USB charger and voltage meter
- Depending on the switch positions:
- Battery powered transceiver & USB charger
- Battery chargeable through power poles
- Bypassed battery for external supply
- Space for all parts of the FTM-400
- Extra space for additional stuff or larger batteries
- No drilling into the crate necessary - everything stays water proof
I have the OpenSCAD file attached if you want to adapt it to your needs, but please respect the CC-BY-SA license.
