I wonder if this could be hacked to our already existing SolarTOH.
To charge a lipo bat from solar there is max1811.
Sadly it is at least 1.3mm thick according to the sheet so we would need another 3d printed TOH also.
My ideal solution would be: .stl files available to selfprint a thicker version of the TOH with space to hold BL-5C or other standard lipo we all have laying around or can acquire cheap.
Plus a pcb with max1811 or comparable to charge the toh-bat via solar and a yet "undetermind" circuit/IC to release charge from toh-bat to jolla-bat if enough juice is available. Some selfsoldering and adaption would be acceptable for this "upgrade".
Already throwing money to my screen but nothing happens :/
