no. avoid lead and deep cycle SLA is a misnomer. only flooded LA have deep cycle charging imo.

10 kW
My understanding is that AGM type LA is capable of deeper discharge than flooded, but that's a side point.
Lead can "work" in an ebike, but performance is very poor. Millions of Chinese are using lead acid to power their electric scooters, but I expect this will be changing over the next few years as their factories get their Li capabilities in order. Lead is a horrible performer for motive applications in virtually every way possible except initial cost.

If you must choose heavy lead, the best bet is to look for a type rated for EV use. Not so much deep cycle, whatever that is, but constructed so that the higher discharge loads of a bike or scooter don't kill the battery so fast.
So look where batteries are sold for power wheelchairs, this will be the right type. Hundreds of types of sla's, not all best for a bike.
I consider lead still useful for bikes and scooters if,
weight will be kept low, 30 pounds the max for bikes. So 3 12v 12 ah cells, or 4 9ah. Trikes can carry more, but 50 pounds is just too much.
Distance to be traveled will be under 10 miles per charge, ideally more like 6 miles per charge. It REALLY helps lead if you only use 50% of your capacity for each ride, then charge immediately. So about 6 miles at 15 mph is the ideal.

You sure are determined to stick with the heavy lead batteries, given your other two threads and replies there.
If you really like the weight and size for less capacity, no one will stop you, but if you want a better solution, you should read around these forums and the ES Wiki as a good start on learning about batteries in general.
It would save you grief and trouble, and save everyone else the time of re-answering questions already asked and answered what seems like a zillion times.
