I know they are not a popular size battery, but does anybody know the maximum charging amps that these batteries can handle?
I know the light I have has onboard charging (I think it’s about 2-3 amps) but takes about 9 hours to charge. I have an external lithium charger that can pump out way more - just wanted to know what they can handle before I try.
I have some QB26800 batteries that can take 9 amps, so I’m assuming the 46950 batteries could and maybe even more (they don’t have protection either)
It’s impossible to answer this question without more information because there’s a HUGE and I mean HUGEEEE difference between a real tabless 46950 and a regular jelly roll in a big can.
If it’s a real tabless cell, and there’s no way to tell if it is or not without taking it apart, unless you somehow bought it straight from the manufacturer or grabbed it out of a wrecked Tesla, but if it is and you’re positive it is…you can fast charge the **** out of them. Tabless cells are amazing. Check out the datasheet for this Eve 46950
Did you do the math on that max continuous charging current they specify? I’m just going to tell you anyways…
It’s 117.2 Amps.
If it’s not a tabless cell…go slow. Really slow. Like 2A maybe.

They are the Lumentop ones.
I wouldn’t say it’s impossible to advise, a C/3 charge rate is quite conservative and should already provide significantly faster charging.
edit : monitoring the temperature is a good idea.
I just charged a 46950 for the first time. Took 12 hrs in the Astrolux EC01X using Anker USB charger.
Well I guess I will stick to the onboard charging then till someone knows better, or more data comes out. It just would have been nice to do a quick charge - I have 2 batteries anyway, that will run all night.
But thanks for all your input!
