Interesting, it is simple enough to use, the question is how reliable is it? I suppose it won’t be worse then the existing charge controller on the S42.
I wish that TI or a more mainstream manufacture had a chip like this, I would trust it a lot more. I could not find anything when search though. Course I am swamped with the GT GB right now.
Can’t speak for reliability but it does have 10+ charges on it. I didn’t thermally sink the chip in the light at all. It does not get hot while charging, mildly warm.
My Clone M3 original charge circuit died on the first use.
Charge chip is made by the same Co that makes the supposedly better 7135 with the claw marking. The TopPower charge chip TP4056 is cloned to death. At least these would be original manufacturer. Minimal parts needed with it as the tiny design shows.
It looks like it has a 1% tolerance, so it could charge up to a max of 2.42v, a bit high for my liking but not totally unacceptable. About what most cheap chargers out there do and getting a better chip would add a lot of cost.
If anyone knows of a better chip like this, please let me know. Otherwise I will look into this chip a bit deeper and see if I can just remake the charging circuit from scratch. It says the chip itself has a very low parasitic drain.
I’m curious about the Astrolux S42 (Nichia 219C) compared to the Astrolux S41 (Nichia 219B) — any idae if using the same 18650 and setting to turbo mode, would their light output be similar? Or are the 2 have different drivers (the have the same BLF A6 UI, except the S42 uses a side e-switch?)
I was just curious. Did you do any work with HaikeLite to help improve their drivers? They are saying their MT09R and recent versions of the MT03 are using a new TA based FET driver, but their own UI. I didn’t know if you assisted them or if they just “borrowed” your driver design.
Kinda sorta. They did ask me if they could use the design in their lights and I offered to help them but they decided to do it on their own and use custom firmware. Why, I have no idea.
I then got a message the other day asking for some kind of help with the drivers, so I am not real sure what is going on with them at the moment. I am hoping that I can talk them into using Narsil at least.
Finally heard back from Banggood on the S42 so I could start work on the driver. They want to use the LY4057 charging circuit which looks like it will work.
Got the main driver almost laid out, then start work on the charging pcb. I am not sure what footprint the USB connector is, still got to track that down.
Tell them how much a success narsil was on the Q8. I’m sure it would increase sales. It’s like a factory custom light. What could I do to mod it? Nothing! Lol
Can you guys give me a little help? When I switch to Group 2, I only get 4 modes (Low,Med2,High1,High2) and I can’t get to turbo. I want to be able to enable memory so I can start at Turbo mode instead of having to cycle through each mode in Group 1.
Mode group 2 only supports those 4 modes. You don’t have access to turbo in that group. You’ll have to use the default mode group 1 if you want turbo. But, then you don’t get mode memory.
