In addition to the said above, I would love to see extended oversized battery available for S1 (from DJI or any third-party). Under oversized I mean just length - if the S1 shell can be cut carefully (an easy DIY project), the extended battery can protrude inside under the main gimbal and turret and I think size-wise it would allow to have a battery with 6 18650 elements instead of current 3, thus doubling the battery capacity. I was thinking of modifying stock battery, but unfortunately its casing is injected molded from thin plastic, and most likely will get destroyed in the process. But any manufacturer with injected molding capabilities should be able to easily do it.

"and most likely will get destroyed in the process."
I couldn't resist opening my battery and even with hindsight, I don't see an easy way of doing this.
The battery doesn't look too bad after being put back together, but the battery is now difficult to remove from the robot. This is the main reason I added the in situ charging capability.
As I've mentioned elsewhere, I was able to add a 3S 5Ah battery in parallel to my S1. Adding the battery in parallel was a pain since I had to match voltage levels of the two battery packs.
Charge balancing is done internally with the intelligent battery so it's not possible (as far as I know) to charge the external battery and the internal pack at the same time.
I think it would be possible to combine the PCB from an Intelligent Battery with higher capacity cells. I don't know if the Intelligent Battery's logic would complain if cells' capacity were much greater than the expected capacity. My gut (with isn't very smart) thinks the Intelligent Battery's logic wouldn't complain about higher capacity cells. |
