I've read the same.

Good read by technomadia. Still a little bit too bleeding edge for me.

I've heard for years now that top charging li ion to 4.2 volts is a lot harder on the life of the battery than to 4.1V per cell.

The OP's post is in regards to small hobbyist batteries, not 12v RV batteries; The moment I saw voltages in excess of 3.6v / cell, I knew the article had nothing to do with 12v LiFePo batteries. It requires four (4) cells to make up one 12v battery, so at 4.2v / cell, that's 16.8v.

Unless your looking for batteries for your toy plane or car, I'd ignore everything in that article, as it has nothing to do with 12v LiFePo.

Another interesting report by users of Lithium batteries for 3.5 years is at the Technomadia website.

Hi Jim,

That article is a bit discouraging. It doesn't address extreme cold either which is an area of weakness.

Thanks for the link.

Good reading. Thanks.
