This project presents a 1A USB Type-C lithium battery charger with integrated battery protection. The design features the XT2025 charging IC, which allows charging current adjustments through a configurable resistor, offering flexibility in battery management. The XB7608 protection chip enhances...
I recently bought a replacement battery for my camera, charged it up, then unplugged it after charging. When I picked up the charger I got a nasty shock.
Is this likely to be a faulty battery? Or could it be the wiring in my home? I need to know where the problem lies.
Nowadays, Lithium batteries are used extensively in portable devices, such as cellphones, laptop computers, electronic gadgets, … etc. There is a standard industry-defined procedure (cycle) for charging the lithium-ion/lithium-polymer batteries, otherwise, the lifetime of the batteries is...
Hi, this is a part of a project I am working at right now. I have a solar panel (12V/20W) and I want to use it to recharge 2 18650 batteries in series and these batteries will be simultaneously powering Arduino nano. My question is: Will the solar panel be able to keep these batteries charged...
Hello Everyone!
I have a 5V chineese wireless gamepad (joypad) that runs on 3 AAA 1.5V batteries, and I want to convert it to power on a single 3.7 LiPo rechargeable battery.
I got an idea which involves using a TP4056 charger module to charge the 3.7V LiPo battery using my 5V wall adapter...
Hi guys,
I am new here and still not an engineer and have not much knowledge in Battery / electricity but have a major project I am working on and would be very happy to get some answers..
I am trying to build a machine that is using a spin motor that work periodically in set times (650...
Hello Everyone,
I am making a custom circuit board with many different parts(dc dc converters, chargers, battery management, battery protection, isolation, etc)....
The product is to run on 18650 Li-ion battery cells, and if you are wondering why I don't use the ones with built in protections...

Hello again,
I have some concerns about how many EMI-filters that I should use for my AC/DC charger?
My charger is operating as a low-power charing (950 W).
I have read in in different articles, that some charger have only one input filter, and in some other cases they also have a output...
Hello all, I'm new here. I'm seeking knowledge and advice about a Lithium ion battery bank that I made. I got these batteries from work out of a device that we replaced the batteries on. It is a somewhat proprietary battery as it is made specifically for this device and not open to the general...
Hi folks
I found this forum via a Google (is your friend0 search. I found some threads loosely related to my question, but nothing specific. Hopefully, some of you electrical/electronic aficionados may be able to assist.
I have an old 'Transwest' brand Regulated Power Supply in good condition...
Hello everyone. I am doing a project in which I use a buck converter to convert high vtg to low vtg.
Actually the input to the buck converter is from a solar panel which puts out 560 mA constant current and 34 V.
And output is a 12V lead acid battery. The N- Channel mosfet is used at high side...
