Hey everyone! I'm Hunter, one of the cofounders of Ohm. Let me know if I can answer any questions.
Lead acid is traditionally very forgiving with regards to temperature. How does the electrical performance of your battery vary with temperature, especially at extremely cold (-40C) and extremely hot (80C) conditions?
...and more on that point, I drive an RX-7 and my engine puts out _extreme_ amounts of heat under the hood. a 50C top-end probably isn't enough for driving on hot days.
I would go for one of these without a second thought because a) though my car is light, reducing more weight helps out loads with performance and b) these things are known to kill alternators and I'd love advance warning of when I might end up stranded without having to test the battery's volts every day.
I'd love to demo one of these.
So yesterday Audi/Porsche/VW announced a new v6 engine that will be used in variations across all their vehicles. Further down the line, they said that engine would include an electric drive component as well, incorporating a battery, effectively making all their cars "hybrids". This seems to be the trend, see racing tech (Formula 1, WEC, etc.). We will probably see this in all new consumer cars sometime soon. Once e…
That day is still a long way away, and once it arrives, there will still be large numbers of classic and modern hot rods on the road. That's not a small market.

The US automotive aftermarket was around $300 billion in 2013.

I seriously doubt that even the majority of vehicles on the road will be EVs within 5 years. And 5 years is plenty of time to develop other innovative automotive products.

Is this really true? It sounded from the article like they're only about $50 more than a typical battery, unless I missed something. I could see some people with normal cars shelling out $50 for the longer life and features to avoid a dead battery, even if the reduced weight doesn't matter much to them.

I've got a 2006 Forester with a manual. I'll occasionally stall it backing out of a parking spot, so I'll have to start it again. For some reason it's much more difficult to start in between cold and warmed up, so it'll take several seconds of cranking to fire back up. If I were to stall it again trying to get going, would I then be in trouble?
It doesn't happen often, perhaps only once a month. But if I'm stuck there for 30 seconds while the LiFe batteries recharge the supercap I'm not going to be happy.

How does that work? If the battery stops providing current to prevent itself from being fully drained, you're not going to have power to the car's computers to actually start anything.
