Hi, I've got an electrical issue with my bike and looking for a bit of advice please. About 2 months ago I had a new Lithium Battery fitted and have had no issues since. Last outing was Thursday last week, did 200 miles with no problems whatsoever. Sunday morning I went to go out and the bike was completely dead, not even enough power to illuminate the dash, let alone turn the bike over. After about 40 minutes on charge the battery had enough juice to power the bike up. I didn't go out on it, I just left the bike switched off for a few hours and when I went back to it, once again all the juice had gone and it was dead. I suspect the battery is fine because a) it's nigh on brand new and b) if I charge it, disconnect from the bike and then reconnect it several hours later, it's still held it's charge. I'm assuming it's something on the bike that's draining it. Only aftermarket part is heated grips but they've been on for ages so not convinced it's to do with them. I had the alarm disconnected by Honda when I bought the bike so it's not that. Some googling of electrical issues on the Blade make me thing Regulator/Rectifier. I am an utterly clueless mechanic so my default would be to take it to my usual garage and have them diagnose/fix the issue. Problem is they're on holiday so if I wait until they're back and can have it I'll have lost a few weeks riding. I thought I'd take a punt, order a replacement reg/rec and fit myself as it looks (just about) within my capabilities. However, when searching for reg/recs I noticed a few specifically state 'not for use with lithium batteries'. This led me to more searches on the subject with the usual mix of responses, some saying it 100% needs to be a specific reg/rec to suit and some saying that's scaremongering nonsense. So now I'm totally confused! 3 options as I see it: 1) Buy this standard pattern one and fit myself: https://www.motoelectrical.co.uk/pr...fier-honda-cbr-1000-rr-2004-2005-2007-rm30019 2) Buy this one as it's for lithium specifically (but not too sure if I can fit myself as not bike specific) https://www.motoelectrical.co.uk/ty...ging voltage for,in it's ideal charging range.: 3) Wait for the garage and miss out on several weeks of biking. Of course, either reg/rec is a punt as I still don't know if it is that but it's a circa £100 gamble I'm willing to take. I could order a multimeter but TBH I'm not convinced I'd trust myself to use it properly and diagnose the issue. Any thoughts/ideas/suggestions very gratefully received. Bike is a RR6 model, circa 24k on clock.
