Backup camera for tractor

[jigs_n_fixtures]

I've found that it's difficult to mount one or even two cameras on a tractor that will show what you need for all types of work. Powering the cameras is also tricky if you want to avoid running wires. Solar is an option but not for heavily shaded areas or at night. I solved these problems by making my own portable camera system.

I took my existing 2 camera wireless system and modified it to use cordless tool batteries. I added strong magnets so the cameras and monitor could be placed almost anywhere. It's sometimes better to put the camera on or near the work, rather than on the tractor.

This idea will work for most camera systems using an adapter for the brand of cordless tool batteries you use.
I don't always need the cameras, so the magnetic mounts are temporary. Most of the time, the system is in a case behind the tractor seat and deployed when necessary.

Word of warning: The DeWalt batteries are monitored and controlled by the tool. So, you have to be careful not to over discharge the batteries.

Yes, this is true. There is no LVC (low voltage cutoff) in the DeWalt battery BMS. As you say, that function is done by the tool. This is not the case with all brands of cordless tool batteries though.

However, if you do over discharge to the point where the battery will no longer accept a charge, there is a trick to fix the issue. You simply put the dead battery in parallel with a charged one of the same voltage. This puts enough charge in the dead battery for the charger to "recognize" it again.

I've over discharged quite a few over the years and have always been able to get them working again using this trick. Doing this repeatedly will eventually damage the battery though.
