I was well impressed with the 4000mAh EVE 40PL 21700 so I thought I would check the 5000mAh 50P 21700 to see how it compared. I wasn't expecting the 50P to be a match for the 40PL at higher currents, but the opposite was the case with the 50P out performing the 40PL at everytest point. It also...
New Li-Ion 1.5v AA batteries from Xtar.
Until now, Li-Ion AA batteries have maintained a steady voltage then died instantly at the end of the discharge, like the Xtar 2500mAh graph shows.
Now Xtar have come up with 3 more gradual ends to the discharge. The 3000mAh has a discharge curve similar...
Finally got testing done and have to take my hat off to Vapcell for such an impressive battery. Even at 60A continuous current it still packs plenty of power. Never got excessively hot either - 75.4°C at 50A, other than that never reached 60°C. Totally outperforms Molicell P30B.
Pretty much. Usually high capacity means not very high current delivery and high current usually means lower capacity. For flashlights 4000mAh is the maximum available.
I have just ordered some and will be interested to see how they test. My instinct is that I wouldn't be rating them at 50A. But the test data on the Vapcell website shows no dropin capacity up to 40A. In fact capacity at 40A is higher than at 2A. I would have said that's impossible, but I am...
Test results for Hohmtech batteries.
I was impressed with the amount of information on the outside of the batteries. All of the batteries were spot on as far as capacity is concerned. Current rating on the 18650s were pretty accurate too. A bit optimistic on the 21700s by my way of thinking.
I...
Another 4000mAh 18650, this time from Mahero. I expect these are the same cells as Enook and Vapcell, Actual capacity measured at 4090mAh. This time I thought I would check how much current they would deliver. And I was surprised. They were going along quite well at 20A, but temperature...
I thought I was going to spend my time watching Home Alone and other festive crap over the next week, but now I am going to be testing HΩ Alone (H Ohm Alone, get it?) and a lot of other interesting looking batteries and charger from the kind people at Hohm Tech. I wanted to try these as soon as...
Looks like 4000mAh will be the go to 18650 battery for the foreseeable. The latest sample to arrive is from Enook, and they are on the butto, actual tested capacity 4084mAh.
A cool touch from Vapcell. Not only are their prices down due to a promotion from Vapcell and an improvement in the exchange rate, Vapcell 18650 batteries now come with individual protective silicone sleeves as well as the usual zipped cases. Handy if you want to carry a single battery in your...
New Vapcell 4000mAh 18650s just arrived. Not only are they down in price due to Vapcell pronotion, but as well as coming with the usual zipped protective case, they also now come with individual silicone protective covers for safe transporting of single batteries.
