Subject: [EVDL] E-Motorcycle battery source
Good evening (or morning, depending on where you are),
I'm looking for a source for 48v batteries for an E-Motorcycle project I'm
going to work
"I would prefer some form of Lithium chemistry battery, with somewhere
between 20 and 40 kWh capacity."
You'd "prefer" a Lithium chemistry?
Nothing else currently available is going to give you a battery of
that capacity that will fit on a 2 wheeled vehicle.
That's a very large capacity
Hi Mathew and All, That will be hard and your only real
choice is Tesla 5kwh, 24vdc modules as the only ones compact, light enough to
put 20kwh in a MC at a reasonable price, about $200/kwh. Others are heavier,
more space. Think about running them at 96vdc though for
If it's a production bike and 48v, chances are it's relatively low power.
My Vectrix is 140v nominal with 18 x leaf modules.
It is possible to fit 135Ah of nmc cells at 140v or so for around 19kwh.
This is a big bike purpose built to be electric.

Yikes. I assumed he meant amp-hours.
Well, if he wants a 60 AH battery, he could make it out of 6 or 7 Nissan

That was my initial thought as well.
To give you an idea, a Nissan Leaf battery pack is 24 kWh, and consists
of 48 battery modules. You could certainly wire up a ~48 volt pack

Yikes. I assumed he meant amp-hours. If it's really kWh, it's a car-size
battery. That's going to be quite a challenge to haul around on a bike.

I've bought 3 LiFePO4 batteries from Ping Battery. They weren't cheap, but
I've been pretty satisfied with all of the batteries so
Good evening (or morning, depending on where you are),

battery, with somewhere between 20 and 40 kWh capacity. Any suggestions?
