What's the BEST battery for eBike?

[Lollandster]

When you configure the CA you only input the amount of cells in series, not the total cell count. So for three parallel connected 16s 10Ah batteries you should input 16 cells 30Ah. If you do use 3 packs you'll also notice that the internal resistance will be 1/3rd.

I have been searching throughout the web for a good 48v battery for my bike and I have actually found that the GM battery is the best battery with a metal casing, that I can find. There are better battery cells like A123 systems and headway, but they are all shrink wrapped and never in a nice metal case like the GM and several worse batteries.

Hmmm you have to find better
My collegae has Headways 10A in metal case and fits well in the bike rack.

where did he get it? I havn't put down any money yet so I'm still open for alternatives.

He get from my tip: elifebike.

They do sell one battery pack in case with Headway cells, but it is the same one that greenbikekit.com sells. It's probably a good pack, but it's only36V and 15A continues BMS. I'm looking for 48v and 30Amps. I'm guessing you might be referring to another pack, but I can't find any other in a case.

So what info on the GM cells would you need?

1) Technology
2) Internal Resistance
3) max allowed charge current
4) max allowed continuous discharge current
5) max allowed peak discharge current
6) # of life cycles
7) Operation Range (Voltages) - actually depends on technology
....

So to recap..

1) LiFePO4
2) .011 - .015 milli ohms
3) 2C
4) 3C
5) 5C
6) > 2000
7) 3.0 to 3.3 volt normal with a min/max of 2.8/3.65

From what I understand all of these numbers are far beyond anything you would need to run the GM conversion kits. The 48V10AH LiFePO4 GM battery has about twice what is required to handle the MP3 peaking at almost 1500 watts on take off.

Any other questions on the GM packs?

Nope I mean that one.
O well you can change the BMS by yourself?
