BSM mentioned the Samsung 30T, shall add the below for good measure….The seller does offer 26980 option as well.
I think with a 21700 you probably do not need a spring bypass already, the springs might be all compressed and coils touching each other so that’s already like ultra low resistance. In all seriousness, be careful, it really might go poof with the 30T. Initial discharge @ 30A load is nearly 3.9V @ 30A, 117W. The light/driver could very well draw more than that since we are removing the springs as the limiting factor and basically li-ion power source as well.
Or even the chinese 26980s if you are taking my 10-12awg bypass post seriously, no matter how lousy you think the chinese cells might seem. I don’t wanna to be blamed as a source of a light killer.
You’re looking at the wrong KeepPower. The 5200mah is an older design. You need to look at the newer KeepPower 6000mah. (The Shockli 5500 is the same battery) This one exceeds the performance of the Liitokala 50A.
Then you also have higher current 26650 cells such as the Golisi 4300mah which can do 30A continuously.
Here is the Golisi against the VTC5A at 30A.
You can also compare the Shockli 4300mah and Ijoy 4200mah as they are close to the Golisi 4300mah.
The biggest “Big 4 Company” batteries are the 21700 cells and the 30T is definitely a heavy hitter.
I see, thanks for the info, learnt something new today.
Was replying to Mattheww1950’s earlier comment regarding using the Keeperpower IMR 5200mAh (2015) in this light, didn’t know that there is a latest 2017 version.
Those new 2017 Keeperpower IMR 26650 6000 (Shockli IMR 5500 2017 ver) curves look good! Esp the Golisi 4300 Gold, savage even at 30A.=, like a 2X capacity version of the Samsung 20S at 30A.
I don't think HKJ has tested the Keeppower 6000mah yet, but it seems widely know that it and the Shockli 5500mah are identical cells with different wrappers.
Here is the link I use as it includes several battery sizes.
Ooops, way late but I buy the bare OSHPark boards from DEL's public postings and reflow them myself - been doing OSHPark reflows for several years now, just wish I had the time to learn a PCB design program so i could tweak up my own layouts.
