  • Yeah I think I might. I was also thinking of fitting a switch at the battery. I can't see there being a parasitic load. I have wired a USB charger in, but I took the fuse out of it.

  • Lithiums are a whole extra can of worms.

    Strange you had the battery go flat. Attach an SAE like @hugo7 suggests. Also use it when the bike turns over to measure voltage drop, and once running see what the regrec is pushing the battery to.

    With lithium you may need a different regrec/mosfet etc

    If the bike is not being used and the battery has been cold for a while then I think its fairly normal.

    Batteries also vary.
