Hi i have a halfords assist bike i want to add a second battery for range anyone in Huddersfield that does the conversion please
I've never done this but I have seen some worrying videos about the risks that can come from connecting two big batteries in parallel. I only mention this to add to your warning tone here.+1 to the above, the 20-30 seconds it takes to swap a battery over is a very minor inconvenience compared to the risks and expense of connecting two batteries together, also simply not carrying the 2nd battery when not needed is easier when you have no need to keep 2 batteries in an identical state
