I am in need of some direction. I am looking to purchase some cells to make a bank. I know kind of what I'm looking for but not exactly. I'm still very new to lithium. I need my cells to operate in the 12 to 14v dc range. Have a high ah along with fast discharge and medium if not high recharge. Not sure if this is even possible. I'm looking for a discharge of around 500+ amps

I might be asking too much but some teaching would be nice.

I hate to see posts like this go unanswered. You want a 12V 500A battery pack?

A lot more info needed to make any suggestions.
Is the 500a discharge continuous or short burst duration,.. Either answer for how long.?
Fast recharge ?...how fast ?
It sounds like a replacement for a car starter battery, but ??
....anything is possible, but to find the best solution , more information is needed.

Hi Robert
That's not very hard
But you do need to give us more data

If it is for a starter pack then your 500 amps is short duration most cells will take 10C for a 15 second burst

So you would need 4 off 50 Amphour cells in series
- this would give 50 amps for one hour - or 500 amps for 6 minutes - in practice it would overheat but 15 seconds should be fine
