Re: Charging whilst cycling touring??

My question though was about faster charging powerbanks. Are there any disadvantages with regard to battery health? The theory is 'fast charging' any battery shortens it life. Having said that ... I believe most of the 'damage' is done as the battery gets hot, so initially -when the battery is cool...

Re: Charging whilst cycling touring??

Re: Could Shimano Generatotr hubs run in oil (including electrical section)

To my knowledge the only electrical machines that work in oil are pure static machines like power transformers where oil basically serves as a dielectric and cooling media. I can't imagine oil in an electrical rotating generator where, despite good mechanical seals, sophisticated bearings or whatsoe...
