Trickle Charger?`

[MavicMover]

I know its not good for battery health but is anyone running some sort of "trickle charger" for their M3 batteries? I'd like to keep them fully charged at all times so when I need to run the drone, it has full capacity.

Whilst knowing that you may kill the batteries in the process ??????
That seems rather strange to me.
However, if you have that kind of money to burn, why not buy enough batteries so that they can do their discharging thing in sequence whilst one or two are always being recharged on any given day ?

Why in the world would you knowingly degrade a Single-Failure-Point of your UAS? Are you working in Emergency Services and trying to be Mission Ready 24/7?

Keeping them FULLY charged is going to cause much quicker degradation. If you need to stay "24/7 Ready" you can implement a Battery Rotation System to where you keep ONE battery fully charged and rotate the stock every single week. This helps to MINIMIZE degradation and spread it across your whole inventory of batteries. Rather than ruining ALL of your batteries quickly you are minimizing this by applying it in percentages across your inventory.

For instance, if you have 4 batteries you're only increasing degradation 1/4 of the time because you're only keeping ONE battery fully charged for a week. Next week rotate the stock and keep battery #2 fully charged. Labeling, rotating, and DOCUMENTING this process will help minimize the damage but know you are increasing the Cost of Operation because you are going to replace batteries more often using this.

This is how we keep our fleet Mission Ready 24/7 for Emergency Services. When called into service we have ONE battery (or flight pack when UAS uses more than one to fly) FULLY Charged and we start charging the fully fleet while enroute to the incident.

I haven't heard the term trickle charger since my RC days, I think there's one stashed in my old rc stuff somewhere. But this was when I used Nicad batteries before Lypos came along. Lypos used to scare me back in the day as I knew someone who lost their truck to a rc lypo fire. Now they are very safe if properly used and stored. I never keep a battery fully charged for more than a couple of days and try to keep them at 50 % or so, just my take.

I've seen lots of chargers and none that have that feature (for any DJI drone model). That's likely due to the fact that trickle charging will do more harm than good.

After finding this on the shelf I can see why the op asked the question. I used this stuff all the time when flying rc. I still have another packed away somewhere. Man I need to go to a trade show.!
