1 year agoIt would be interesting to see what the actual stats are for pedestrian deaths vs miles driven for non autonomous cars. I’m willing to bet autonomous cars will ultimately be safer, but it will take time to get to that point.
Edit: Apparently, according to the transportation safety in the US article on Wikipedia, the average is 1.25 pedestrians killed per 100 million miles driven.
I’ve recently replaced my 12v 400ah agm battery bank with lifepo4 batteries. I dropped 400lbs in weight and essentially doubled usable capacity. The negatives in that blog don’t seem all that bad unless your specific use case would be specifically affected by them. In my case, the energy density of the new batteries is irrelevant. I’m not overly concerned about cold weather performance, as this is for a recreational vehicle, and we don’t use it often in the winter. Even when we do it’s only a night or two, so reduced capacity in that moment wouldn’t be a problem. It seems the biggest concern is buying your batteries from a reputable source with a decent warranty in the event you get one with manufacturer defects.
At the end of the day, all the various chemistries have their pros and cons. For me, the lifepo4 batteries seemed to fit the nice middle ground between agm and li-ion batteries in regards to weight and price, being both affordable and significantly lighter than agm batteries.
All that said, I’m just some random person on the Internet, with my personal perspective clouding my opinion.
