12V/3000mAh Lithium ion Battery Pack

I made the AMT Enterprise D model and lighted it straight wire using 12 volt led strips. I only used two independent 12 volt led’s with resistors to light the busard collectors. (The red glowing things) All static no flashers. I initially used a nine volt battery as a power supply but was disappointed with the brightness. This battery pack did the trick and increased the brightness by approximately 50%. I had to cut off one of the male plugs, pig tail it and solder it to the positive/negative wires I used to light the model. None of the reviews I read mentioned using this as a power source for modeling so I thought I would. It will work great for such projects. The photo was taken during daytime hours and the lights are still very visible.

This battery has a sleek look and a small size. It can be used with a variety of items and has a long battery life. Charges fast and stays charged for a long time. Excellent value. I purchased 2 more similar to this one. It has a led to show your battery life

Works great!

I have some special equipment that requires a battery pack and needed to replace one, originally it was only provided by the manufacturer of the device. I put the specs into Amazon and found this and it was the identical battery pack for a much better price. I have since received and used this several times and I believe it is the same one. If you need a battery and this fits your needs, it is excellent.

This power supply is great for upping the 5V voltage to 12V on my Arduino Motor Shield V2 by externally powering it via its positive and negative terminals. I can now run 12V motors without an issue... Almost. This thing only has one input/output barrel jack, where this would generally be an okay option for passthrough charging, in my case it doesn't work at all. I am splitting this power and stepping it down to 5V on one side going to a Jetson Nano, and the 12V that is split and not stepped down goes directly into the Arduino motor shield V2 board. The reason I am not just putting it directly into my Arduino Mega is because I am using the USB for serial communication, which means it will send power over that regardless and if I try to add 12 more volts it will damage my components most likely. This is where the input/output single barrel jack issue comes into play. I would be able to charge this battery with it off and not send power to the rest of my circuitry if it had a separate output. But with the splitter it still sends power down the line to my motor shield V2 and the jetson nano from the wall. However the wall power is not enough for the motor shield v2 to run the motors when split between itself and the battery in its off state. If it was I could look passed this issue. All in all its a little disappointing that I will have to make the battery removeable for charging (most likely using a 3d printed case to slide it into on the bot), but it's not the end of the world, as when I am not trying to pass through charge and I am just using battery power for the bot directly from the bank everything works as intended. If you wanted this battery to be more multi-faceted for developers and makers like me, possibly consider removing the power button all together and implementing a switch in the DC chord maybe, and then give it one input DC port and one output DC port. A 12V 3A battery with 2 DC ports in and out at an affordable price would be a product I'd buy for almost ever build lol. All in all its a solid battery, it just isn't exactly what I wanted originally. Had to get my hands on it to see first though!

I have a small bissness stop pond otters we run out of these electrical parts from wholesalers, but this amazon saler never let's us down always fair price great quality well packages & on time shipping

Great purchase and works well with the strip lights that I purchased! True to description and easy charging.

Muy buen producto.

Very nice compact 12-volt battery pack. I use this for my wifi camera for my truck and trailer. Lasts about 30-40 hours per charge.

Works perfect for giving a non portable pump a new free lease on life. Best of both worlds, strong power and portability. We haven’t had any issues with the pack not lasting, but we make sure to plug it in between uses

This is my first week using this battery. It is excellent value. I'm using it to power my Milwaukee Heated Hoodie. The general operating procedures for me is as follows: start on high for 20 minutes, then turn down to low. The jacket is warm enough down to about -20°c on low. The battery is slightly bigger than deck of cards, certainly smaller than a cell phone. Light weight , I don't notice it in my pocket. The battery last about 6 hours with 3 lights of capacity left. This would seem to last an estimated 6 to 8 hours on low heat. The M12 battery 3 amp only last about 3 hours and is very bulky in the side pocket I would buy it again.

Super achat

Liked the built in charge indicator lights. Good to have a supplied charging splitter cable. Battery has a decent capacity for its size.
