The title says it all. Vapcell has been requesting the development of some new high discharge cylindrical cells to certain OEMs for already some time, and they're harvesting the benefits. In the small cell category (10440, 16340, 14500) they already launched the Vapcell INR10440 320mAh (3 A) and...

Mmmkay saw this half a day ago or so and I must admit I've been fighting against myself to avoid buying what I don't really need. I also catched a cold prior to this AliExpress sale frenzy and I'm running some fever, making my @#$% harder. Someone in BLF posted a 21700 4000mAh Shockli deal which...

It's mostly cooked, but take a look at the following BLF thread. It may be of interest to you: The making of a BLF charger: the start of a new venture It's gonna have a lot of advanced features while aiming to avoid being overly expensive. We'll see. :rolleyes:

Loong time without stepping in here. :pop: Let me show you something good, for the daring and knowledgeable among you: Test of Vapcell IFR26650 2600mAh (Red) @ lygte-info.dk Wow with the graphs fellows! :eek: The hotter cell reached +17°C over ambient after a 30A continuous discharge, this...

VBatty 32700 3.2V 7000mAh (Grey) review @ lygte-info.dk Related discussion thread @ BudgetLightForum Looks like one of the temp sensors was not correctly placed but, anyway, the 35A maximum continuous rating is plausible: at 30A cell reached +30°C over ambient temperature, with +34°C...

A few months ago I inquired Henrik whether he could review a couple 18650 LiFePO₄ cells from Heter Battery sold under ENERpower brand at NKON: HTCFR18650-1100mAh-3.2V “33A” HTCFR18650-1800mAh-3.2V “3C”, check out the review @ lygte-info.dk: Wellp, given the excellent result attained by the...

Source: maukka in Review request for HKJ [Rechargeable Batteries] | BudgetLightForum.com Impressive. Those are what I'd call safe li-ion batteries. Hope they can improve their energy to mass and volume ratios soon. Cheers :)

Apexium INR18650 2600mAh (25A) review @ lygte-info.dk Made this VS VTC5A comparative screenshot: Definitively not a bad power cell seems to be. :pop: Apexium site link: Apexium Battery | Home :: Apexium I wonder who is the OEM making these. Cheers :)

Received one a couple days ago. Onboard voltmeter is within ±0.02V, and it features internal trimpots for both voltmeter and amperimeter adjustment. Ampmeter is spot on according to my multimeter. Maximum output voltage goes up to ≈31.6V. I have this BF-2A battery holder on the way. Together...

Datasheet: http://www.datasheetspdf.com/datasheet/download.php?id=1165169 A super-affordable cell aimed at the light electric vehicle market. No serious reviews of it yet. Piqued my interest because of its very affordable pricing and comparatively nice official figures (a Samsung ICR18650-26F/J...

Vapcell INR18650 2000mAh (Black) @ lygte-info.dk 38A? :glug: Cells only went up to ≈+34°C above ambient so, despite the low capacity, those 38A continuous may as well be true! Know what? The shape of the discharge curves looks like those of the Samsung 30T, the shape of the cell smells...

Aspire INR18350 1300mAh (Black-yellow) @ lygte-info.dk Highlights: True peak capacity: nearly 1200mAh. True 10A continuous cell. Doesn't overheats even at 15A, though voltage sag is very noticeable at this level. Can be found here: Aspire 18350 Battery (15A 1300mAh) - $4.00 : Aspire online...

From Amazon: BestKalint IMR 26650 90A 4500mAh Li-mn Rechargeable Battery with Flat Top (2 pcs) A little math, of course. Given that the best high discharge 26650 cells' internal resistance figures still are above 20mΩ, even considering the best state of charge conditions (4 to 4.2V) we have...

Test of Shockli IMR26650 5500mAh (Black) 2017 This seems to be the latest cell from PLB (高一致性3.7V 5500mAh 镍钴锰酸锂大容量三元动力锂电池|储能锂电池 生产厂家-东莞力朗电池科技有限公司), the OEM behind the LiitoKala 26650-50A. It's current handling ability is a bit worse, yet it probably is the most capacious 26650 in the market...

HKJ just published this: Test of Aspire ICR18650 2500mAh (Black-yellow) ≈2400mAh peak capacity, ≈2300mAh at 10A/20A down to 2.8V, ≈1550mAh at 20A down to 3.2V An average of ≈45°C above ambient at the end of a 20A continuous discharge. Decent cell, seems it can't compete with branded...

The 8205A is a dual N-channel MOSFET in a common drain configuration, it is a custom tailored MOSFET IC for battery management applications. According to the FS8205A (Fortune Semiconductor Corporation) datasheet I am looking at, for VGS=2.5V its RDS(ON) is 27/35mΩ (typ/max). The DW01A battery...

The 50A discharge curves are mostly missing because HKJ's battery holder melted. He needs some high amp discharge equipment upgrade. The 40A curve was done in free air, if not at least one of the cells would have gotten a tad above 80°C absolute temp limit (55+°C above ambient). Probably a...

Link: Test of Vbatty IMR18650 3000mAh V30 (Blue-gold) A tad ludicrous 40A pulse rating, doesn't it? :rolleyes: Cheers :)

:lol::lol::lol::lol::lol: Cheers :)

LiitoKala INR26650-50A 5000mAh (Cyan) Best Bang for the Buck award, imho. My predictions were about right, or so it seems. :eek::oops::wub::w00t::pervy: Cheers ;)
