This Canadian has extreme use needs. This video was made for motorcycles but I think transfers well for EV's. He demonstrates flooded lead, gel, sealed and lithium 12v starting batteries what we need in our EVs to run the 12v system. Surprisingly the little lithium does not perform as well as I thought it should and there is a reason. Testing against the 9 ah motorcycle batteries with 500CCA the lithium had very similar CCA. I was puzzled. Then the reveal. The "9" ah lithium was in reality a 3ah battery. So they based their ratings like light bulbs. Going for lumen. In this case what was shown is you only need a third the capacity in lithium to equal a lead storage battery. When I size the Leaf 12v battery I am going to look for a battery a third the size in capacity...maybe even less. Lawrence Rhodes https://youtu.be/3ywopGAXP-I
