Hello there,
I've recently come across a post about limn2o4 calendar life:
http://www.pedelecs.co.uk/forum/electric-bicycles/10206-voltage-drop-lifepo4-v-limn2o4.html
It is said that it looses in average 14% of the battery capacity every year. With battery utilisation that will also decrease the total capacity, I believe the battery would loose at least 30-40% of its capacity after 2 years... which mean that it's time to change battery.
I think this is the battery I purchased from Conhismotor:

And this chemistry is very similar to the NiCoMn from BMSBattery:

These batteries have more Wh/kg than lifepo4. But at what cost? How long does that live? And is limn2o4 = NiCoMn?
I don't know what to trust anymore :lol:
Maybe lipo and lifepo4 are the only reliable batteries now...
