Li-Po cell Id.

Post by dacflyer »

I got some various cells that I salvaged from battery packs. but I can't find any data on them.
Does anyone know of a site that has a data base for li-po cells ?
I can find plenty of data for 18650 li-ion cells etc, but none for the polymer cells.

the cells i have are......
LGHD54A5566
LGH6468L
ICP103450S
I plan on making some small battery packs / banks with them.

I found the ICP103450s here: https://www.tme.eu/en/details/accu-icp1 ... cp103450s/

Not having much luck with the other numbers. :(
But, if you know what they came out of, you could then maybe find the battery in the spec's of the device.

Edit:
The other two you listed, seem to be made by LG.{Maybe} :roll:
But I can't be certain, since I can't find anything except ones that fit cell-phones.
Can you post some pic's?
So, I can try comparing them to the ones that I found.

i'll have to take some pix..but these came out of laptop batteries..i'm guessing apple products, they seem to be the only ones using Li-po packs, everyone else seems to be using the 18650 cells.
but the Li-po cells are flat, bout 1/4" thick, and average bout 2" x 3.5" approx.

I found a PDF on the Spec's of the SamSung ICP103450s here: https://4444.com.pl/download/icp103450s.pdf

It shows that the cell is 3.7V at 2000mAH.
Plus, includes the charging spec's, testing, and failure information.

thanx, at least that's one..
i already built me 1 stack of 6 cells 3S2P it is about the size of a Klondike bar , i hooked it to my old 1980's boom box, and it played for over 12 hours at half volume.. i'm really amazed. normally the boom box uses 8 D-Batteries. And this little pack can outlast 3-4 sets of D cells.
I'm impressed..

Cool. :cool:

The 6 3S2P cells are just 18650 cells, right?

Though, In looking up the 3S2P Battery Packs.
I find 12V packs with different mAH ratings.
From 4400mAH, up to 9750mAH.

Since your using older cells, I'm thinking the pack you made should be about 4000mAH,
given that the individual cells are each rated at 2000mAH.

dacflyer- What are you using to charge that 6-cell pack? Individual cell chargers I hope.

Tzap, Aren't the cells in series? That increases the voltage of the pack, it does not increase the AmpHours.

They're not all in series.
You would have 3 cells in series = about 11.2V.
Then take another 3 cells in series, and put it in parallel with that set of cells.
This will double the Amp Hours.

I like this description of series vs. parallel connections - https://zbattery.com/Connecting-Batteri ... r-Parallel
May the passion to build be with you!

i am using BMS boards.
i have been making all kinds of battery packs for a while. mostly 18650 packs. of all the cells i use, they average close to 2AH
i test and analyze all my cells, using a OPUS charger / analyzer
i was just curious about the capacity of the flat pack li-po cells.
the 18650 cells, i can find all kinds of info on them easily

i just saw the comment about series and parallel.. a lot of the lithium packs now days have that mixed configuration.
so many times you'll see... 3S4P= 3 cells in series and 4 sets in parallel , or 14S10P = 14 cells in series and 10 sets in parallel.
