Default Lets talk lithium car batterys

So as the title says, lithium car batterys, lithium amp hours, what are they equivelant to?
10 lithium amp hours is equal to how many amp hours from say, a xp3000. Just meaning dry cell battery.
No specifics just lithium vs competitor.
Besides the fact they cost an arm, leg, and left nut, what makes them so much better?

Are they worthy?

Compare to say supercaps?

LiPo Ah ratings are equalivelant to regular AGM. The main advantage is the amount of power the battery sustains over the dis-charge rate. As well as re-charge. Most AGM batteries are limited to ~40A max current charge before they start to overheat. Where LiPo have something like ~80A max. So in theroy they can be charged twice as fast.
As of right now LiPo isn't designed for the discharge rates we demand. they are better suited for a sustained low amp draw more then high instananos discharge.

They also require very specfic charging similar to AGM batteries. So a special charger is needed to realy maximize the life of the battery.

At this point in time LiPo really has no advantages in our field. The costs are just to great to even justifiy using them. So just stick to tried and true AGM and you wil be good.

Sounds good.

I just had been browsing around, and they seem pretty legit. But it all makes sense, thank you.

You mentioned that they are good for low discharge or amp draw, so wouldn't that be good for demos or no?
