SOT23-5 LiFePO4 protection IC? 13D1S?

[eccerr0r]

I have a SOT23-5 marked

"13D1 S"

I wonder if anyone recognizes this IC? It should be a LiFePO4 protection IC, but having problems finding the datasheet, anyone recognize this?

G00gl3 returns a 6-pin LDO which is not quite right...

As far as I can tell, this IC apparently protects overcharge and overdischarge, as wells being a balance controller (with external driver). Trying to figure out a possibly broken BMS, and due to the lack of usual ICs and transistors on this BMS I can only assume it's an all-in-one single cell protection/balancing IC.

That would be my guess as well seeing how it is setup like I have seen a lot of in this configuration the ones that have one ic chip for this particular purpose I have not seen any YouTube video on how can change how many battery cells you want to use so my assumption is that if it can be done it might be very difficult to do

But you can buy a couple of BMS protection boards that are not completely populated and configure it to how many battery cells you need for your application I have done this in the past and it has worked flawlessly the issue I had was when one of the battery cells went bad was the only issue that I have had

I need to create a 6.4 battery pack that can handle 12 amps but ones I have seen already made are 6 amps maximum the 9.6 volt one that I also bought are rated for 12 amps maximum so I going to remove one set of battery monitoring circuit components and change it from 3 battery cells down to two battery cells

oh no, this leads to the possibility there's crap on the other side of the board...

Crap! there is... ugh. This is bad, screwed up my plans... sigh.

Well, thanks, this is still a good lead on what to do with this board... maybe it's not so bad after all ... or not ... or don't know yet. Time to study.

Do you know where you can buy these BMS protection boards from using these ic chips any help would be greatly appreciated
