I bought a shido battery for my triumph a year ago, but due to work, covid etc etc, it sat on the shelf in my garage.
The bike saw the outside world for the first time last weekend and I fitted this 'old' battery in the expectation that it would need charging. No such thing, it fired up staright away. Way better than anyway lead acid I've ever used.
Also, by coincidence I've been looking into using large banks of LiFePO4 batteries for a project at work. And I'd sum it up thus; if you buy a battery that already has BMS (not all do), then you can pretty much forget about the charging. As long as it's high enough, you'll be ok. The BMS cuts off charging above a certain voltage and limits the charge current too. Now, I clearly can't vouch for all BMS, but the ones I've seen all do.
