I suspect that it is price that's holding back their introduction, they are expensive,
It's certainly not existing Li-ion stocks, since these are made just to match demand due to their self ageing characteristics, hence them intermittently not being available.
If there's no progress in us getting these for our bikes by the Spring, I'll happily buy one of these inserts and try it, but i won't bother in winter cycling conditions. Masochism isn't one of my strong points!
