Works as expected

Simple product with a simple job done well. I have three of these. For each one I have built a supporting arm that suspends the light bulbs in the air in order to keep other things from being damaged by the heat given off from the bulbs.

They work.

Very handy to help drain out batteries to storage levels, or to check after-flight levels. Voltage calibration seems to be a crapshoot between units, some read higher than others. Haven’t found any info on how to calibrate so apparently that isn’t do-able. But better than nothing!
