Over the past couple of months, we have been working on a "smartification kit" to obtain accurate state of charge for Lithium batteries. Currently most systems use voltage based capacity estimation which is inaccurate and make it hard for flyers to
- maximize their flight time
- understand changes to battery capacity over time
- choose from the best pack among the many-in-hand to race with
Batmon helps solve all of the above issues and also automatically discharges the battery to storage voltage after set-time to enhance the life of the pack.
The board currently works with modified pixhawk, ardupilot and arduino firmware. More details about the kit is available here: https://github.com/rotoye/batmon_reader
We also help assemble custom lithium ion and polymer packs with Batmon integrated for your specialized use case.
