Glad I found your video. I bought the Soshine batteries for my i3t 2 eos after watching your previous comparison videos. And then i encountered the drastic power drop on the Soshine batteries. I thought I received a bad batch of batteries. I will switch back to 3.7v pk cells for my i3t 2 eos going forward.
I’ve been using PK li ions in my i3t for years and never had a problem with the lights. Guess I’ll have to grab some Life batteries for them. I’ll use the li ions in the i3t2s. Good info thanks
Nice video. Thanks for putting out that result so other people can see it. It's just too bad I invested my money in those soshine and had to learn the hard way. Might get myself a old iT3 to get use out of them
Thank you very much for doing this test!!! However, this is a bittersweet result, for sure… I have an i3t and an i3t 2 in my P.O. Box waiting for me to get home, as well as some Soshines on the way. I have plenty of 10440s that I’ve been running in my Foursevens Preon P1 and can put in the i3t 2, so I guess the Soshines will be reserved for the older i3t.
i use lifepo4 AAs and AAAs in all my electronics. just wire in a spacer so 1 battery replaces 2. i bought a bunch of brass circuit board standoff that are approx half the length of a AAA, and just screw them togeather and use as a conductive spacer. if they dont fit well i just wrap some al foil around the spacer. for AA's i bought the actual spacers and do the same al foil trick, just wrap the outside with them. the problem is charging them, i just use some magnets and a couple strips of metal and attach them all in parellel to a lab bench power supply and let them do their thing until theyre at 3.65v. big advantage of lifepo4 over lipol is the lack of battery degredation. they will never stop being useful. I do use the soshine 9v batteries which are just 2 in series lipol cells without any boost converter and charge a similar way to ~8.4v
Good info and thanks for sharing! I don’t think LiFePO4s will take over in the flashlight industry but I’d at least like to see some representation in the market.
You might want to consider getting a 10850/10880/10900 battery like those for the Nebo, Ledlenser, ASP, Streamlight, and Reylight “2x AAA” sized lights. I just ordered a few 10880s from Reylight to put in my Foursevens Preons. I really like the output but am tired of the short runtimes of 10440s in the short body tubes (Preon P1), so I’ve been using the long body tubes (Preon P2) and NiMH, but output is underwhelming.
@@AH-xw7gy 18350 is where i think the sweet spot is for removable batteries. current edc is the trust fire mini x3 and trust fire minix. really only want to carry lights with uv mode now days
I use the soshine 3.2 life po4 in my i3e eos. Works very well. Less hot than 10440 with good output and runtime. Unfortunate the life po are not great in the new i3t.
Very interesting! Do you prefer the i3T2 with 3.7 batteries or the i3T with 3.2 batteries? Does it come down to brightness advantage for the 3.7/i3T2 vs runtime advantage for the 3.2/i3T? If so, how big is the brightness advantage? How big is the runtime advantage? Is there a heat difference?
Very good questions. As for heat, the original i3T with 10440s is the hottest (around 125 degrees Fahrenheit at room temperature when I checked). The i3T 2 has less heat and brightness but better runtimes. These results can be seen in the i3T vs. i3T 2 10440 video I made earlier. The driver improvement really helps the i3T 2. I personally still use the i3T and will switch to the i3T 2 when my i3T eventually retires. I kinda want to see how long the trusty brown i3T lasts and have somewhat of an irrational attachment to it at this point haha.

Sorry I didn’t know sooner but glad the video could help at least know that it’s not just you experiencing the drop off.
@PardonMyEnglish keep up the good work! I love your videos. They are very informative 👍

Sorry you had to be the one to find out the hard way but thanks for sharing so others could learn!

Glad you will get some good use out of them. Thanks for sharing your experience so others could learn!
One thing I've noticed is the original i3t is by far the coolest running light I use even compared to lights that come with a lithium battery
I have 2 desert tan I3t olights and an 8 pack of 10440 pk cells. I like this combo thanks to your videos.
Nice! The combo still works well for me too 👍

Nice! I use the Soshines in my keychain light as well. I’ve found it to be a good balance of output and heat as well 🤜🤛
