So there are 2 big hill that i have to go up total less than 1km. i can pedal a little bit (both knees hurt) to help my xiongda 48 volt 2speed hub that draws 15 A max. so there need not to be much watthour but rather it would need high continous discharge since i would only put one cell or 2 in parallel. iwant something light. even thought li ion provide good discharge and amp hour per weight i m not willing to gamble with all the hazards and risk. sorry. i look at life po4 wich can emit gaz but rarely ignite.
a battery able to deliver 15 amp is the minimum i want to achieve but if it cost not too much more, i would like better the battery to be able to deliver 30 ampcontinuous since i migth have to end up adding another motor on front wheel if i dont have enough traction in winter needing maybe the front wheel with a q100 similar motor to also provide some effort in case the back wheel sliding on ice snow. Im not there yet, ill try with only one motor but if it does not cost too much more i would rather build a battery that can handle 2 x 15 amps continous or simply a more powerfull motor for futur.
i am willing to solder yes (even more if it not directly on the cells ( like it would be easier to use a setup like the liitokala pict with pre)
iam willing to screw but not to spot weld (unless there is a very easy and cheap way to get a spot welder ... not so encline on the idea though.)
i beleive there are pouch , rectangles and cylindrical lifepo4 available at the moment
A))) ?which good cells provide high discharge that i could use for this setup available genuine sourced?
------
LIke how many of these on ebay liitokala would be needed for a 48v battery and would that be a good idea cause some article say they are fake?
B))is it possible to find genuine liitokala ?where. on ebay they are about 8dollar per cell but i dont know if there really have the spec inside the cell. with this setup i would not have to buy a NESE wich ends up cheaper to build i think. or maybe those cells are a not to be found genuine anywhere..
---
C))maybe to consider Headway cells would be apropriate ?can we get genuine ones atm?
----
D))like how many A123 ANR26650 40 amp continous (are genuine ones still available?) in serie to have 48v? do they also comme with prewelded tabs or i would have to use the NESE module?
feel free to tell me the setups that could answer my 2 hills only problem with my xionda (possible a second hub in front for the future) anything that is light setup(no liion) that can do job that ends up a good bang for buck without me having to spotweld?
thanks
