Hi volks, hey @WFmarketing
While this overall topic was discussed over pages of threads, there are two things I could not find after hours of reading:
- What is the max. acceptable voltage? I’m planning to use 4-6pcs of 20700 batteries in parallel.
This will give me 19-28Ah with a nominal voltage of 3.7V (max. 106Wh).
After charging, these Li-Ion batteries peak at about 4.1-4.2V. I’d like to use them connected directly to the SKY, so I can see how the voltage drops and at which time a recharge is required.
Can the SKY accept this voltage without problems?
Any voltage-regulator would output a rather constant voltage which makes it impossible to see how the battery empties.
- In order to bring the power into the SKY, I’d like to use the bottom-connectors with some 3D-printed adapter. I could start to measure and with some trial & error, but - is there a chance to get a 3D model / shape from WF?
A drawing would be good too, whatever
I can use Autodesk-Inventor files (IPT) as well as STEP, SAT, IGES, DXF, DWG etc.
Once I finish my pack (which is not even started yet due to the information above is missing), I’ll publish a manual for you guys.
