Designing to prevent Lost Bootloader Issue without battery

Hello Particle forums,

Using the Electron in the field I have seen a number of devices come back with the Lost Bootloader problem.

In my application we use a truck’s 12V power supply and use a 1000 UF cap per the recommendation in the Datasheet. So we don’t have a battery we can use to keep above 20%. Adding a battery is not possible due to cost.

I was wondering if there was a recommendation for how I can design my board such that this Lost Firmware does not happen in the first place? I have full control over the design of the board.

Thanks!
