Should I Build A 52v 24ah Lithium Battery For An Ebike Build?

[ArcticWolf]

Hi, first time on the forums so not sure if this is the right place, but I would like to make an ebike due to my other one breaking (china made controller :/). I was wondering how hard would it be to make one, I have soldering skills but I was told that id have to use a spot welder or something and my friend said that if I crashed on my bike that it would burst into flames if it hit the batteries so I dont know. I was looking on Lunacycle.com and im planning to buy their fat wheel 1000w conversion kit (Works with 52v for 1450w) then I saw the price of the battery, $750, more than the cost of the bike and the motor combined :/....So yeah, iv read this guide and understand what I need to do but I am questioning the safety of it. Thanks! and if you have tips for me leave a reply .

Hi,

most people in this forum deal with batteries only on a single cell basis.
You might want to search the "endless sphere forum" where the ebike enthusiasts hang out.

Generally, I do not recommend soldering directly on a cell's body. If you want to build your own pack from round cells, assemble a large bunch of 18650 battery holders, this is easier.
I am about to assemble a 16s5p pack of A123 cells this way.
If you are not totally sure of what you are doing, search "ping batterys"; Ping builds really good ones for a good price.
