Hello all,

does any1 use LiFePo4 cells as an ICE car starting battery?
I am very curious if that would work with that less weight, more power - cells. :)

Thank you!

One item to keep in mind on my previous response.

For some reason, I read this as a question specifically about ThunderSky
cells. Going back and reading the question again, the question was more
general.

My comments on current draw and prices were specific to cells like TS.
Other lithium technologies are more willing to supply higher current, but
might also cost more too.

Mike

I haven't tried it, but I don't think they would be very happy.

I have the 100Ah cells. It would take 4 of them to be the equivalent of a
12V starting battery. That is going to be a fair amount larger than most
standard 12V car batteries. It would be lighter, but what would you use the
extra power for? I don't think the battery would like seeing its major
current drain being at a few hundred amps on a regular basis. It wouldn't
last long, but 2C to 3C (200A to 300A for a 100Ah cell) is about all they
like to see for discharge.

You could use smaller cells (down to 40 Ah), and get closer to a 12V
starting battery size, but then the starting current draw would be even
larger relative to the battery capacity.

Also, today's prices for 4 - 100Ah cells would be almost $600. Kind of
pricey!

Mike

Ive heard about Headway 8Ah cells, and because of their very high discharge capability (20C) they should be the ideal ones for such operations I think. What do you think?

My V8 requires less than 200 Amps to start.

I have a set of A123 cells I will be using for a starting battery for my ICE
3-cyl Midget (note this is not an EV topic).

This will shave 40-lbs off the weight of the car!
The A123 cells can do 100C, 2.2amp = 220 amps * 5 = 1100 amps.
20 cells at $15 each = $300.
For a V8 that can need 2000 amps the cost can escalate rather quickly.
But consider the costs of reducing weight in a car in other ways,
and it might not be that expensive. Look at what Titanium bolts cost,
or a carbon-fiber driveshaft..

Would (1) of these be equivalent to (4) of the single cells ?
If so, it would save a lot of connection points.

Has anyone seen any pricing on these ?

Subject: Re: [EVDL] LiFe(Y)PO4 as starting battery for ICE car?

Would (1) of these be equivalent to (4) of the single cells ?
If so, it would save a lot of connection points.

Has anyone seen any pricing on these ?

I think they're betting that if they over specify the battery that
they can get way with never charging the batteries to full capacity.
So they're never balanced (top or bottom to avoid a lively
discussion). They just take and release a specified amount of energy.

I'd like to see some data as to how many cycles you lose wit this
approach, or if there is some dumb technology to be sure that one cell
doesn't die without detection and ruin the pack (and your day).
