Hello for now, I have recently been in possession of a Yamaha YZF R1 Rn32 Bj. 2016 and have the problem that the machine sometimes does not start because the battery (Shido Lithium LTZ7S/YTZ7S 12V/6AH) is too “weak” (?) at the first start attempt or even after a few days without driving, is already empty. Sounds like a problem with the battery, but I have already bought a new one and the problem has nevertheless occurred. It is a lithium battery, so it can also be due to the minus degrees of the last weeks, which this battery type does not put away so well. I would like a mobile starting aid, which in the best case is quite compact and which I can connect directly to my motorcycle. My plan was the following: 1. To have a starting aid cable (ring eyelets to EC5 plug) permanently on the battery and to have access from the outside. 2. A starting aid power bank with EC5 connector, which I can connect if necessary. I have my Bed Is an EC5 connector better or a SAE connector? 3. Is there something to consider when starting a lithium battery? (some of these start-up power banks probably only work with lead batteries and I haven’t found one for lithium so far) I would be very happy about help, as I’ve been researching this topic for days, but I don’t really get smart about it… Maybe there is already someone who has such a assembly himself and can tell me the components? Thank you in advance, Leander
