Hi together, after watching Will’s second video on LTO batteries I thought I share my LTO/BCAP replacement built for my car. Since my car used to eat up lead batteries roughly every two years, my initial idea was to build a replacement with BCAPs only as I was not convinced by LiFePO4 car...

I would rather say, that even with only one string of cells the capacitors are not necessary at all, at least not for the car I have. Neither the alternator nor the starter do exceed the maximum charge/discharge rate of 10C. Doubling the capacity by adding another string sounds reasonable...

Unfortunately, the alternator being water cooled is a sealed unit. Thus, the regulator itself is not accessible. Maybe I can tweak it by changing the voltage on the control terminal though - have not tried that, yet.

Hi together, I am looking for a high current load tester and stumbled over carbon pile load testers as for instance the DHC500A2. Does anyone know which carbon pile resistor element is actually used in this load tester and whether it is available separately? Or does anyone have a picture of the...

I was just watching your battery monitor (half an hour ago) and noticed that the PV voltage dropped periodically every 10 seconds. Am I correct that this is the charge controller probing the PV output?
