In some of Wolf's repeated test of 18650's it was evident that the cell capacity reduced with repeated charging/discharging/charging, and that makes sense.
I'm building a 4S9P 18650 pack to run a 4-metre strip of 5050 LED's plus a security camera.
I have a 250 watt 12 voltMono panel to charge the pack via a 30 amp Epever MTTP Charge Controller.
I'll reduce the voltage to 12 volts with a variable buck converter.
The LED strip will get only occasional use - say 2 nights a week for 3 to 4 hours PN and the camera is motion-controlled so little use there also.
Given the little usage the battery will receive would I be better off just charging the battery from grid supply as required (I'll be monitoring voltage), rather than using Solar?
Solar will (attempt) to charge every day and I'm concerned about increased loss of capacity over time.
