Is anyone here from Europe, who could sell charging chip BQ735?
From China it takes a quite long time .
Thanks

Well, due to my grid tie inverter not accepting high voltages, and the fact that the lions in my solar panels are 36V (72-cell) I think I need to stick with 72-cell.
However I have a few smaller panels that are 36, 32, and two 30-cell. The 36 and 32 together run at 75% efficiency (and subtract more with additional inefficiencies) when running in parallel with the 72-cell panels. The kicker is that the two 30s... generate 0% power when connected in parallel(!)
So now what to do with these small panels?
I could sell them...
Or I could shim them.... -
Can you please give your opinion on this matter?
Laptop does not work. I checked voltages of charging circuit BQ24735 .
Values are :
pin 20: VCC 19V
pin 6: ACDET > 2.4V
pin 16: REGN 6V
pin 5: ACOK 2.62V
Are these values correct and (if BQ24735 is working in the correct way)
ACDRV (pin 4) should have more than 19V?
Or I must check any other values to be sure to decide that BQ24735 is faulty?
AS I have ACDRV about zero, so I guess BQ24735... -

I have been looking at some battery packs that they recently brought in and I was debating whether to buy them because of cost of the shipping especially one of the two battery packs that I had bought from this sale that they have going on right now

Had a curly one on a BQ735 battery controller and an Asus X555DG motherboard and thought I'd share the fix.
Board not powering on, no 19V past the first input FET PQ8801 (ACFET in the datasheet). All FET's around the BQ735 all measured ok and no obvious signs of corrosion. Board boots fine if this first FET is bypassed, however no battery charging in this event.
ACDET, ACOK, VCC etc all ok on the BQ735. PQ8801's input gate is being driven off ACDRV, with source for that being CMSRC. Note that CMSRC is on the source of the FET, and ACDRV drives the gate. So initially for...
