    Help needed in identifying this 5050 mm 1W emitter

    Hello. I got a roll of these. There is no datasheet, except the info written on the roll. Manufacturer unknown. Light quality is really good, so I'd like to put them in use, but unsure of current. Seller says - 350mA Maybe anyone can ID them, based on outline and soldering pad shape?

    Anyone can help identifying this LED flashilight driver board?

    SOIC is not marked. This is some generic chinese MCU. 8 pin chips are deliberately scratched, to avoid reading of the model. One of them as I believe, is mosfet driver.

    Need recommendation for 1.5v rechargeable AA's

    These are some chinese 1.5V rechargeable batteries, which have lithium cell inside and boost/charge circuitry too. They work almost fine, except the following issues: 1. They are not suited for light loads - say using them in TV remote will drain them too quickly. 2. They are not suited for...

    Anyone can help identifying this LED flashilight driver board?

    Hello. Got bunch of these from a friend. At 4.2 volts, red light keeps flashing and there's no output. At 6V green led comes on and there's an output (classic 5 mode). At 8.4V board emits smoke and dies. Any ideas what this could be and what are the specs?

    Any info about Ford Fusion Hybrid Li-Ion batteries?

    Joking? it's a sealed can :D Do you usually open your 18650 -s just to inspect their guts? :D The whole package from the car is rated at 1.4kw, and it houses 76 cells in series. If we divide numbers. capacity per cell is roughly 4300mAh, in line with my measurements.

    Any info about Ford Fusion Hybrid Li-Ion batteries?

    Interesting observation - I charged them with 4.10 volts (default setting for Li-ion batteries @ turnigy) - they delivered 4000mAh. Now charged them with 4.20 volts - they delivered 4300mAh. So idea that they can be 4.35V type makes a good sense. Is there any way to clarify that cell is 4.2V or...

    Any info about Ford Fusion Hybrid Li-Ion batteries?

    Well, I have no info, when I got them, they both were at 3.65. Charge completed at 4.15 (turnigy acucell). Discharged them to 3V, below it voltage fell down too quickly. As I've been told (unverified source), these are designed for 200 amp continuous drain current, hence the dimensions....

    Any info about Ford Fusion Hybrid Li-Ion batteries?

    Yes I have all required test equipment, measurements just finished and they measured 3976mAh the first one and 4001 mAh another. Discharged at 4A. Now they're charging and will try to discharge them at 10A, to see if there will be any difference. Btw, discharge at 4A had zero effect on their...

    Any info about Ford Fusion Hybrid Li-Ion batteries?

    Nope. They are large, prismatic cells. About 7 pieces of 18650 cells in size. So I expect totally different currents and capacities :D

    Any info about Ford Fusion Hybrid Li-Ion batteries?

    Hello, long time no post here. I want to build a high power (50-100w) LED work light, which would run for overnight, if needed. So I need really juicy battery. Batteries are getting expensive, but I have a friend at local car dismantling facility, and he said, that he got some Ford Fusion Hybrid...
