SBD I’m not sure if I misread this.. as far as I am aware the MP has 2 batteries 1 under each seat, I think the leisure battery is under the passenger seat RHD models...
I have a lithium battery on my motorbike, it’s a 1996 model and just did a straight swap for the lead acid. I’ve had no problems with it. It’s a fraction of the weight and smaller than the original..
Surely all this management is for the likes of Tesla and fast charging banks of lithium ?
There is a third stop/start battery under the drivers seat behind the starter battery box, it's accessed by removing the plastic trim;
Yep lithium is the way to go, same physical size, much lighter, twice the capacity, can be charged quicker and more fully from an alternator.
(with the right charging system) For my use it would mean off grid power 12 months of the year without an ugly solar panel on the roof.
Your bike has a standard alternator not a smart one, it hasn't regenerative breaking and it doesn't have a leisure battery that needs charging when the engine is running and disconnected from the starter battery when stopped.
All lithium batteries have a built in battery management system, it's for safety, your sitting on it after all, performance and longevity, it keeps all the cells equalised and prevents charging at -0c temps.
Because of the BMS some manufactures claim their
leisure batteries are drop in replacements, in some cases they probably are, but I'd question that on an MP especially as there is so much info missing regarding the electrics. This is an interesting video by Vicron Energy
How not to blow up your alternator
For reference the leisure/starter batteries are accessed by pulling the side panel/pocket off the driver/passenger seat.
This is the leisure Battery, the starter is similar.
