Weight pure and simple. Imagine a forklift battery in a car!At that 48kWh in this application (and likely even for a fork lift) would actually have a sensible depth of discharge to 50%. Did you not notice the “IMO” in my post?
LiPO4 batteries have a far longer lifespan (far more cycle life) , are lighter/smaller, no maintenance requirements, etc, etc. you might wonder why they don’t fit lead acid batteries in EVs?
Look at the whole life costs instead of the cheaper capital cost is my advice to anyone buying batteries.
Where weight is of no concern lead acid is still king.
