Guys, i just received the lights like 5mins ago. They isntalled the Sofirn batteries in the lights when i opened it. The batteries are Dead! I cant on the lights with them and when i try to charge using Liito, it foesnt even register any charge!
I’ll join the other thread, but Im not sure this advice is correct. If the source charger is strict about negotiating charge levels, it will probably not work even if you use a C to A converter. The data lines simply pass through.
I don’t have my first LT1 yet, and I think I only have a single type C source in my possession so I can’t really try this.
The leds are on high I think, at least this is how it came from Sofirn. When the light is switched on on the lower outputs, it is much lower. I have not messed with the trimmer yet, but certainly will because I just changed the leds with 1600K 90CRI Luminus Cube leds. Will post in the WDYMT thread.
Here’s the driver, as good as I can picture it with all those wires. Picture of the battery side is a few pages back in this thread.
USB-A has far less conductors than USB-C (4 vs 12, respectively). Therefore, a USB-C to A adapter should cause the charger to see the connected device as an older non-USB-C device and charge using 5V. I don’t have an LT1 yet so I can’t test, but I have the Apple 30W and 87W PD chargers and an Anker 30W PD charger and often use all of these to charge older devices (which I assume don’t have the USB-C pull-down resistors).
I have used many different cable configurations with these chargers from USB-C to micro-B, C to Lightning, C to A with A to C adapter, etc. All work with non-USB-C devices at 5V.
I’m not an expert, but that locks easy to fix for the hobby user. Glue Rd on the PCB and connect Rd on A5 or B5 on the port and a connection to ground. And secure the resistor and wires with the red celastic.
I am not 100% sure without testing if this enables charging with a C-C cable, but there is enough space for the bodge job.
Yes. There is most likely a clear insulating sticker on the negative terminals. It is very difficult to see. Just run your fingernail or a butter knife over the edge and you’ll catch it.
As Rayoui says, a properly implemented USB-C plug to USB-A socket adaptor is supposed to have the 5.1kΩ pull-down resistor built in.
These adaptors are strictly defined in the USB-C specification so that older USB devices that have no way of knowing about USB-C power protocols can still receive power (at 5V only) from a USB-C port through such an adaptor.
The same thing happened to me with my BLF A6. I thought the battery was bad but then I remembered that every light I’ve gotten with a battery has had that insulating film. I’m not sure why they don’t use film with some color like Olight.
Supposedly one of the reasons for the transition from mini-USB to micro-USB was durability. Mini-USB connectors were designed for a minimum of 5,000 connection and disconnection cycles (with the male connector failing before the female, since it’s usually cheaper to replace a cable than a device). Micro-USB connectors, according to the spec, should handle twice that—a minimum of 10,000 connection and disconnection cycles.
This is all theoretical numbers on paper for me. I don’t think I’ve ever had either a micro-USB or mini-USB cable connector fail on me (though I’ve lost cables to my cats’ teeth and have had phone USB ports die).
Back on topic, since my current phone supports USB PD, about half the charging ports in my house and office are USB C with PD, which won’t work with the LT1. OTOH, I’m a nerd about my batteries and would rather charge them in my SkyRC MC3000 and record data from each charging session, so I don’t expect to use the onboard charging much. If Sofirn fixes the USB C charging issues in a future batch, there’s a good chance I’ll get another LT1 at that point and find a new home for my batch 2 LT1.
