Some asked me about how Windows 10 reports the battery status (charging level, power left, etc.) when using my experimental 2S Li-Ion battery "without the fuel gauge IC" over that 10-pin connector.
I retested my configuration and have to report that "it is not accurate nor trustworthy at all".
Several reasons and the main one is "mine cannot report the current flow thru the battery pack", thus only voltage level (on the LPA side, not the battery pack terminal side) is measured.
So it depends on the battery quality, battery discharge cycle times (battery age), specific battery's internal design, and the goofy/unpredictability of Windows charging/discharging estimation algorithm, the reported value can vary a lot.

Yet still an important message to take in: the battery charging circuit (CC then CV) still works. So in a way, the battery pack is doing its things.
Taping a sheet of paper on Windows' battery status reporting area probably helps more than having a status report at all.
Yes, I found that neither Macos nor Windows could display battery capacity correctly. Didn't LPA design this?

Quote Didn't LPA design this?

This thread is just an investigative effort, as DIY under maker's spirit.
As I had stated, my DIY method does not have fuel gauge IC + I2C connection so no unreal expectations.

If the topic is why LP does not have an official support for battery pack, that's a different question.
I'd advise to go back to LPA's kickstarter campaign to see if there is a claim/promise on "a battery pack" or "any battery pack" support clause.
(then the slippery slope on what does the word "support" cover?)
BTW, the battery pack that we know "sort of" works is the Cube i7/i9 type. LP does not sell/support it AFAIK.

My point is, if this is about a commercial/mass produced/long term supported product, the expectation would be higher.
For a product like that, I'd say, go for a Cube i9 laptop and call it a day.
< --- Sorry have to point this out. It is not what we do not wish LP can do more and evolve/getting better-n-better, but how it got worded...

I don't mean that.
I hope the authorities can give us some advice on how to buy battery packs so that we can use LPA better.

Finally! I found it. Battery connector type is Molex PanelMate™ 51146.

Is anyone in the US interested in buying one of these battery pack for the LPA? I used it and it work flawlessly. Looking to let mine go, will sell for cheap and ship immediately! DM me if you are interested!

Has it been sold yet? If not, can I ask you to put it aside until the end of the coronavirus epidemic? Of course, I'll send a part of the payment straight away, as to prove I'm not going to ghost you.
