Li-ion Battery Chargers: TI BQ24092 compared to Microchip MCP73833/4

<< < (3/3)

jpanhalt:
I saw that battery the other day at Adafruit.   I do have a battery tab CD welder I built years ago for NiCd's and have used it for Li-ion tabs, but the Li-poly batteries I have used were already set up with leads.

I am not too worried about the specifics of the battery right now.  With all that's going on right now, I suspect PCB delays will increase , so I wanted to get into line.

mariush:
You should consider NOT using OEM batteries like that Samsung one.

There are companies selling such batteries in volume, and they're reasonably priced.

For example:

8.3$ at 50pcs 900mAh, 850pcs in stock : https://www.digikey.com/product-detail/en/jauch-quartz/LP603443JU-PCM-WIRES-70MM/1908-1365-ND/9560987

8.5$ at 50pcs 1350mAh, 870 pcs in stock : https://www.digikey.com/product-detail/en/jauch-quartz/LP503759JU-PCM-2-WIRES-70MM/1908-1369-ND/9560991

same 1450 mAh 840pcs : https://www.digikey.com/product-detail/en/jauch-quartz/LP103048JU-PCM-WIRES-70MM/1908-1370-ND/9560992

They also have an Adafruit battery at 9.5$ at 50pcs, 1200mAh : https://www.digikey.com/product-detail/en/adafruit-industries-llc/258/1528-1838-ND/5054544

tme.eu  has them for less than 4.5$ if you order 50-100 at a time, but shipping them to US would probably cost or take a lot of time as they would not be shipped by air

450mAh 3.86$/100 https://www.tme.eu/ro/en/details/accu-lp502248_cl/rechargeable-batteries/cellevia-batteries/l502248/
