I am looking into these batteries. As of now, i only know that the difference between the two are costs and charging efficiency What other pros and cons are there?
If you use a lead-acid battery that lasts 10 years (a tubular plate battery) that is capable of 2000 cycles down to 25% capacity, then the lead-acid battery works out at about half the price of Lithium, and in case of failure, individual cells may be replaced.Initial cost, but total cost of ownership over 10y is 25 - 30% of lead.
I'll have to take your word for it, never come across a manufacturer offering such a beast...If you use a lead-acid battery that lasts 10 years (a tubular plate battery) that is capable of 2000 cycles down to 25% capacity, then the lead-acid battery works out at about half the price of Lithium, and in case of failure, individual cells may be replaced.
LiFePO4 is one of the safer, if not the safest, rechargeable chemistries. It has none of the thermal runaway issues that Li-ion has, is relative easy to charge and the costs are dropping fast. When you're paralysed on a wheelchair, running away if it catches fire isn't an option!I like old-school lead-acid due to its low initial cost, its safety (other than hydrogen explosions), and ease of charging, but there are obviously good reasons to go with lithium-ion.

According to the Leoch data sheet a 12v 110Ah tubular SLA is 0.0121m^3 and weighs 30kg, giving 1160Wh,Lead Acid doesn't seem much larger than a Lithium Ferrophosphate, but at 1.6 tonnes for 48V/840Ah rather heavier.
840Ah @ 48V = 40kWh(your 840Ah example I'd estimate @ 12v as 8200Wh, so 8200/400kg = 2.05Wh/kg! I know lead-acid doesn't scale well but that's rubbish)
Ah, I put decimal point in the wrong place, mine should have read 20.5Wh/kg840Ah @ 48V = 40kWh
40kWh/1600kg = 25.2 Wh/kg
(not fogetting that that includes the weight of the tank - It's the reading on the pallet-truck when I move it)
I tried that with 6 dead MK, no scrapper nearby wanted them, certainly weren't interested in paying for them anything that justified my travelling costs. They went to my council recycling centre, who incidentally will take lithium too.the scrap-man will give you about £500 for a dead lead-acid battery. A similarly sized Li-ion battery might cost your £500 to dispose of it.
