    Really cheap true cc/cv usb charging board

    I guess I'll use the second solution. I'll put the 4 boards and power supplies inside the modified charger box, and use a 5 pin din connector to connect them all to the batteries.

    Really cheap true cc/cv usb charging board

    That's not gonna be possible. I don't have space for all those power supplies inside the pack, plus the boards. Also I don't want to bring out lots of wires. Maybe I could use one of these: Ebay item: 251403347508 I don't know if this works as charger (making cc/cv) or just as protection. If...

    Really cheap true cc/cv usb charging board

    I'm planning on making a pack with 4 18650 in series, to convert the battery of an old cordless NiCad drill to Lithium. I wanted to use 4 of these boards to charge the batteries, one for each, to charge them individually while connected in series, with the series circuit open. Then all the...

    TRUSTFIRE X9 xml-t6

    The xm-l T6 is rated 1000 lumens driven at 3A. If the current supplied to the led is lower than 3A, the output of the led will also be lower. In that situation the led will not be working at it's maximum. That (as i see it) is an underdriven led.

    Cree XM-L T6 on 1x18650. How many lumens?

    I was looking info on this light and found this thread. I thought that a flashlight with a small form factor like this one couldn't be on high mode for more than a few minutes without toasting the emitter. Now i'm pretty amazed to see that you actually drained a AW cell in high mode. Is this...

    Really cheap true cc/cv usb charging board

    I also looked at a couple of those chargers, and some cheap others like ebay item: 390310966680, or ebay item: 280855992241, but for me, the big problem with all of them is that i don't know what's inside. They might follow a cc/cv algorithm, but there is no way for me to know that. On the other...

    Babying LiOn batteries

    Using only the values on that table, and interpolating between them, i get the best overall value at 62,5% DoD with 1250 cicles. At 75% DoD i get the same overall value with 1000 cicles, as at 50% DoD with 1500 cicles, and only 4% worse than the best value. Based on this, i would usually go...

    Really cheap true cc/cv usb charging board

    Really cheap true cc/cv usb charging board

    Hello everybody! I'm a new member in this community. I always liked flashlights but i was unaware that there were people addicted to them. I have a cheap 3xAAA flashlight that i modded with an R2 drop in. I use it all the time in my work (i'm a mechanical engineer and i work in a brick...
