Looks like a home built project. The cells are available as are the bits and pieces, BMS and such. Fairly pricey project. 36 cells of 18650 at $6 to $12 each. BUT 500+ charges to 80%

I would only go lithium if i was garenteed 1000+ @ 80%
(like my 120ah 48v headway pack in my emax 110s which is well into 650 charges so far)

Why is 1000 the magic number? Li-NMC save £'s and $'s sooner than that. We must be just using different examples. That being said I'm with you on Headway. They will be one of my next buys in configured packs. I'm hearing well over 1000 from a number of posters, with confirmation of their use.

cost vs charges

A good lead acid at the moment can handle 300 charges and a 12v 12ah battery costs £20

where as

A good lithium can handle 1000 charges 11v 12ah and costs £80

so 3 lead acid packs will give about the same amount of charges as the lithium
£60 vs 80 but with the weight saving of the lithium they perform about the same
so 1000 charges is the magic number

to get the most out of lithium you need to go big
so ampage per cell is low at maximum discharge
then ul get the value

ie for my eco scooter
im running 10ah at 48v lead acid at the moment
to get value out of a lithium battery Il need a min 20ah at 52v (for the discharge rate and cycles)
(im shooting at 30ah 52v)
otherwise im better off with lead

unless max range is an issue
not overall cost per cycle
pick your poison

(for somthing small lead wins 10-18ah)
(18-25ah its a bit of a draw)
(25-1000ah lithium wins as long as you get the cycles)
(this is my educated opinion and someone will find falt but its a good guide line)

but to be honest most scooters (100w-1000w are scrap after 500 cycles 2-3 years
and a chain sprocket tires brakes and a overhall are a must at this point
so most people just get somthing new and sell there old one's to someone on here so we can trouble shoot them
running lithium in something like these are pointless
big and custom is where lithium makes sence
