How to use TP5100 2A 8.4/4.2V 1S and 2S Lithium Battery Charger DIY

[@josep.3364]

Thank you for reviewing this module, and also great review! Just a note, you can not apply your time to charge calculation, since the current will lower once cell reaches near 4.2volts, the real time might be something like 3 hours depending on the type of cell.

[@robojax]

you are welcome. Agreed with your statement.

[@celeron.26]

Hello Sir. Thank you so much for the very clear explaination. This is way better than TP4056 charging module. 😊

[@deankay4434]

Mr. Shamshiri, I truly enjoy your videos with the thought process, planning and the abundance of information you provide. After all, it takes work to video, edit and review your work and I find it flawless. Even corrections. I have an entire line of cordless tools for sears back when I could work. I am prepared to disassemble and pass judgment on each cell. How or what math is used to determine the current to charge cells the show promise? A dead battery is dead, but unless it has a dead short internally, it has a chance to live again. I take the numbers stamped on the shrink wrap and research to find voltage but aH info. I can not order every single cell ti fix each battery pack as it would be cost prohibiting for my wallet. But having 9 perfectly good tools sitting on the shelf does me no good. Automotive ASE Master Tech since 1978-Retired I have already used your excellent product testing videos to pick two modules to purchase. Thank you again!

[@robojax]

Mr. Kay, I am pleased that you like my tutorials. Yes indeed for each video there is lots of efforts. Very few such as yourself know this. first of all battery capacity and charge parameters are the most tricky part of working with them. The charge current is determined by the manufacturer of the battery. charging above the rated current will reduce the battery life. So you have to find the datasheet. for example for the Panasonic battery shown in video here is the datasheet www.batteryspace.com/prod-specs/NCR18650B.pdf and it says the the standard charge should be about 16550mA. or lower. I have spoken about battery protection in this video kzbin.info/www/bejne/aZXacmt3bbulqKc so generally for less than 10Ah batteries, always go 0.5 of capacity or lower to protect it.

[@deankay4434]

@@robojax Thank you again so much for the reply. I will identify and look for data sheet & their recommendations. I have never posted a video on youtube, but have a great understanding on lighting, camera angle or position, just a lot. This is basics, but you go a long way to provide information at least I find extraordinary and as accurate. You have my total respect in your total presentation. My last job had me holding automotive technical 4 hr. seminars for 20 to over 100 each night during a whole week in a different town or city. So the old “Dog & Pony” show. Taking photos, screen captured from a lab scope or scan-tool to use these in the power point was not in the job description. But the presentation had diagnostic holes in it, large enough to drive a truck thru. Advanced Charging systems, Serial Data (6 types in GM vehicles), etc. Magneto-Reological-Fluid used in struts in place of traditional oil and valving found in a common shock. Called “Active Ride Control” and other terms, but basically tiny metal particles suspended in oil. When a magnetic field is applied at a variable rate, change at 2mS changes from a thin less viscous oil to a rigid hard non-fluid material. This was started in suspension in 2004 Corvette. Acura used it in rubber motor mounts. When ran on a dynamometer, the vibration generated on up shifts, down shifts, all parameters, they mapped the dial-in amperage required was downloaded into a EEPROM and allowed later to change the ride feel, smooth, sport, racing anything they wanted. So, electronics coupled with mechanical applications is amazing. So a basic understanding was needed to pass along to guys/gals who may have to work around these or replace them, then recalibrate. Total electric vehicles make no noise (Very Little) but I joked two decades ago that waterproof speakers could be added to allow the driver to turn a knob to make it sound like a hot rod V8, 10 cylinder Viper or a loud 4 cylinder w/turbo. No, people on phones walk into streets and get hurt or killed. Laws maybe passed requiring them to make noise. The possibilities are endless. Just sharing as the guy who makes a simple kit can patent this (Installed by customer on older vehicles) but make millions, if a manufacture buys the patent or the rights with a percentage for license for each one sold/used. It’s a gold rush, but few would think of it or pursue it. I have ideas. Ok, enough. Blessing to you & loved ones! Thank you again. I could be reached as I am just working on my own old truck for me. A project to keep both hands & mind working at 62. Stay safe!

[@robojax]

Hello, Mr. Kay, You are welcome and I am glad you like my tutorials. You've got so much experience. wow. I've read your comments and enjoy them. To make electric cars noise, many states have considered/did pass legislation to to make it mandatory to have noise added. I am not sure if it has been implement or not. I have an Arduino course which starts from absolute beginners and up bit.ly/rj-udemy God bless you too and your family. you too stay safe.

Hello! I've got a question. As soon as the battery is fully charged, the red LED will turn off the the blue one one turn on instead, right?

Thank you so much and your videos are super useful for us beginners!

Good review man. But which resistor need to changed to adjust the charging current?

[@genmckoy]

Is Bms not needed to charge my 18650 batteries with Tp5100? Or Bms still needed to charge safely all my batteries? Thank you and hopefully to get an answer from you.

[@robojax]

this is BMS. you BMS h as protection. But can't control the current as to how much should go to your battery. this module can allow up to 2A. but if you connect a small battery with capacity of for example 500mAh and charge it with 2A, it will get damaged. So you need to connect a power source to this with controlled current (ampere). that's why connected your charger that controls the maximum current. An example of a charger would be a step down converter with constant Voltage (CV) and constant Current (CC). So you set the output of that to 8.4V (for charging two cells) and set the current to 200mA or whatever value your battery require. if allow more charge current that your batter require, battery get damaged. So find out about your battery's charge current. Good luck

this will not charge if a battery is dead. When you see battery is not charge, check the voltage, isolate the bad battery and use new one. this is the cheapest charger. We don't expect this to detect the cells.

[@Boediprasetya]

@@frankfernandes648 for S2... if the battery that is going to be charged is damaged, one of the things that happens is: 1. if Short damage will result in over current because the TP5100 is equipped with over current protection. 2. If open damaged, charging will not occur because an open circuit

[@anandsingh8987]

Can I use two chips in parallel to get max current upto 3Amp ? Awesome video

[@robojax]

Thanks. Yes you can if you set both voltage at exact values. Slight difference of voltage causes the current to flow from one to the other and waste the energy.

Sir can we charge 2 lithium-ion batteries from 1 TP4056 board🙏🙏

Watch the video please

Mr. Ahmed shamshiri from canada, valuable video from you. Please make videos for 3s bms board and tp4056 module. And there’s a new tp5100 which is charger and boost up volt in one module. How work and how wiring. Greetings from Saudi Arabia. Thanks.

Assalamu alaikum Mr. "Allahu Akbar", I am glad you found my videos helpful. TP4056 is for 1S see datasheet here dlnmh9ip6v2uc.cloudfront.net/datasheets/Prototyping/TP4056.pdf See my other videos on chargers kzbin.infosearch?query=charger

What is the input voltage and its source?

Is that thermal imager any device? Or mobile application?🤔

[@robojax]

It it a thermal camera, I just added the link to the device in the description of this video.

Bro!, Please help me!. I'm changing the battery system of my bt speaker. My amplifier is xy-p15w 8-24v dc. Which one is better? 4 18650 in parallel and use IP2312 then use converter 3.7v to 12v or 2s2p 18650 and use TP5100 then use converter 8.4v-12v? I want fast charging using 33 watts fast charger of poco x3 nfc

My question is my sony srs xb 32 battery 5 pin connector 2 red wire 2 black wire 1 yellow wire .. how it works yellow wire .pls reply me

[@robojax]

I am not sure about that model, each battery cell needs one wire and we need one common ground.

[@sandeepsalaria9518]

@@robojax without ground new bms other modal it was working yes or no

[@robojax]

Without ground means you want not turning a light with one wire. No.

[@neswblvck7512]

Can use 12V or 9V ?

[@artist1128]

Thanks for share~~

[@eko653]

Kinda bit dissapointed you havent tried connecting those in parallel to see if it gives 4A .. or tried connecting 2of those 2s in series for 4s charger.. :( Or even better I need a 7s charger.. so output voltage 29.4v Would 4 of them work combining 3 in 8.4 and one in 4.2? Or is there a diferent module that is cheaper? Can I use 7 of these in 8.4v for 58.8v e bike charger constant 2A? That would be a cheap Af solution Please let me know Edit: also. In theory if the charger can charge 8.4v at 2A it's 16.8W of power. This means this charger could be modified to charge 4A 4.2v cell? With those resistors? Please test this for us. I highly appriciate your work

[@robojax]

Parallel is not a good idea but it work. why not good idea? over time modules change the output voltage a little. that little variation in voltage causes the current to flow from ONE into the OHTHER and that is waste of energy. Very few like less than 0.1% of people will configure this for higher current.

[@eko653]

@@robojax but is it possle for high current?

you want to me to repeat my previous comment. yes and no. Read it please.
