I believe the current partners all have different form factors and industry standards that they need to adopt. For eg. Janus truck standard cartridge format versus an intregrated batery for a small drone. The developped form factor for each and the casings would need to be provided as a detailed data sheet for that exact product
I have spent the last few years dealing with the procurement of commercial drones in some extreme environments and all of the detailed analysis to identify the best offering was around the batteries.
- Temp and humidity upper and low limits
- Class of charging (speed)
- What temp range the battery needs to be within to activate a high class of charging rate
- How long can a battery with more that 80 percent capacity be stored for
- What level of off gas is present when charging is tight physical batches
- Weight to power ration of finshed product with casing and charge terminals etc
Heres a screengrab of the section of a typical drone battery. Its for an exact developped battery system to plug into a 3rd party drone. Developped for that exact drone
