I guess the LG M26 is a cost effective low drain cell, much like the Samsung 26F/26H/26J. Got a 4-pack of protected 26F cells on sale for less than $9 a few days ago in AliExpress, still on sale for just a tad more (with S&H to Spain, of course).
Still undecided here, my friend said nothing yet. The quoted shipping and handling charges to some other members previously scared me somehow. If S&H is under or at ≈$1 per cell to where I live I may bite, I see FastTech only adds ≈$0.60 per cell to ship via Sweden Post to my country but of course I understand FT is FT. Maybe a dozen for us but as I said this is undecided yet.
I’m on the fence with the shipping charges as well. Trisky, is it possible to give us an idea where the steps are in the shipping charges?
level 1 price - 1 to x cells
level 2 price - (x+1) to y cells
and so on.
You gave me a price via PM for 20 cells as I asked, thank you. I’m not sure how many cells I can add to that without bumping up to the ‘next’ shipping charge. This may help sell more cells.
Batteries can't just look at very external parameters
Samsung 26F 2600mAH is a very high-quality electrical core, good product consistency, high cycle life
The quality of LG M26 is average
Sanyo UR18650FM 2600mAH is more expensive, close to the cost price of 3 U.S. dollars
But it's still used by many companies
Then the retail market of foreign trade is very confusing, many fakes, you will detect discrimination? That's a low price, a dime a share. Many domestic electric cores are used for rewap fake vtc5,25r etc
Or fake 25R uses 22P, fake HG2 uses MG1 or MH1,VTC5A use vtc5
I guess you got such a cheap samsung26f
There are two possible, fake 26F or used 26F, positive and negative will leave traces of welding，disassembled from the battery pack
I think the product is good. That shop was entitling itself as “Colaier Direct Sales Store” some time ago. They may have some old stock to get rid of, protected cells may be somewhat unappealing to people… but in any case I am pretty sure they avoid declaring shipping of li-ion cells to get super-cheap shipping costs for these packages (more than a month to reach home).
I am just curious how much does the seller charge to ship to you in Spain? US $54.74 to Australia for 4 pieces of batteries is just crazy. Even if you are buying 10 pieces of batteries, this shipping charge is still too expensive.
If there is savings going with cheaper shipping option, I am more than happy to wait 4-6 weeks. The “Free” shipping from suppliers like GB and BG typically takes 4-6 weeks to get to me in Australia anyway.
OK
I have four unprotected GA cells.
Two were discharged to 0V by a flashlight with extremely high parasitic drain and were at that 0V for a full week.
All four charge normal
All four hold a charge normal
None get hot during charge
All four have an internal resistance between 20 and 40
Still I don’t use them and I can’t tell them apart now.
I know there are dentrides in two.
So now that is seems normal to use cells like this please experts tell me how I can sniff out the two dangerous cells.
I can’t use any without seriously endangering my family and material possessions.
The Miller, with regards to discerning the supposedly damaged cells one of the easiests ways would be to capacity test all of them on an analyzing charger. The cells which suffered a one week long 0V “break” should show a perceptible reduction in capacity.
Another way, for example, would be to charge-balance all 4 cells and set them in series, proceeding to discharge them with a constant light load of some sort while monitoring cell voltages. One way to make this unattended is equipping the cells with equal 1S BMS circuits. Damaged cells will go down earlier and their final resting voltages after weakest cell cut-off should be noticeably lower.
