Panasonic CGR18650 Cell Specifications

I would think these are one of the first li-ion 18650-cells (1st generation) from Panasonic which could mean, that their stock IR could be very high (>=80-90), but without data from others or a more detailed spec-sheet, I can not use them without concerns. (They are not heaters at 750mA charging).

Slight clarification. The OP asked about a panel config rated for 21.7a - e.g. 2p. But the charge controller unit has a 18a max input. I''m not saying the panels would produce more than 21.7a but that they could produce up to 21.7a if

"Good" IR for common 18650 cells

For those interested in IR and wanting to know what a "good" IR is for various cells I''ve put together the following table. This was built from a combination of Wolf, 100kWh Hunter, and my own data. All IR measurements were taken with a 4-wire Kelvin type AC 1kHz impedance tester, specifically...

18650 best soldering technique? | Second Life Storage & Solar

Soldering iron: 70W Taiyo ElectricPX-401, set to ~390C,with 5mm diameter"large tip for high thermal-storage", but cut at anangle to allow pointed contact. Solder: Standard 60/40 rosin core, 1mm diameter I think this technique works well, because: 1) The rosin has no time to boil away and gets to work immediately, maximizing its effectiveness

a spreadsheet for 18650 mAh prediction? | Second Life Storage

The life cycle is not a linear line. It''s more like a curve. Without knowing where at on the curve in life cycles, you can''t predict how many are left based on the mAh the cell charges to. There are many cells that have had an easy life, gone through 100''s of cycles, and still perform 80% of their rated capacity.

Results of Capacity Testing 18650s for 1,600+ Cycles | Page 2 | Second

The first row is the average of Cycles 1-5 and the second row is the average of Cycles 201-205 for each cell. The third row shows the percentage of degradation of eachcell. Please keep in mind that the LG cell did not start out this test as a new cell, and already had a number of cycles or cycle equivalents on it before the test got started.

How to Properly Use 18650 Battery Pack Builder?

I have a few hundred Headway LFP cells that I tested for capacity and IR. I want to make some 4S battery banks for car audio. I would like to make some different ah configurations probably from 16ah (2P) all the way up to 96ah (12P), but for now let''s assume I''d like to just make some 48ah...

I''ve actually had good success bringing 0v cells back to life. I first started by parallel''ing a good with a bad for 20 seconds, then on the D4. End game is to feed 100% of house solar to the grid and use second system for household usage with the added benefit of having power during outages. I''ll have to look at grid backup and battery

18650 advice for beginner | Second Life Storage & Solar

And since you are new here, it may be tempting to buy some high capacity 18650''s online for real cheap. Be aware, there are absolutely zero 18650, 25650, or similarly sized cells that are higher capacity than 3500-4000mAh. They are scams. And anything that has the word "Fire" in the name, take that as a warning not a name.

Sony US18650GR (G6) Cell Specifications

Thanks very much for this information. I recently got about 150 of these cells. Most tested in the 1400-1700 mAh range.Now I can check to see if they are still reasonable cells (G3-G5), or well used and closer to end of life(G6+).

Samsung ICR 18650 26D Panasonic CGR18650E The Samsung cells I have had very good success rate, most are testing to be over 2500mah, so practically new. The panasonic cells come in second. Their cells have tested every single time to be above 2000mah per cell, with none going below that. The sanyo cells come in third.

18650 vs other cells?

Regular 18650''s won''t discharge as much as Vape batteries, and that''s actually a good thing. When you have 100 cells in parallel, you can easily hit 100A with ''old crap'' @1A each. With Vape batteries, that could be 2000A which is overkill and I''m guessing that Vape batteries don''t last as long as 18650''s but I could be wrong.
