USB Battery charger + 10A BMS - Interesting, right?

🔥I want a battery cell charger with USB connector easy to use but also to have an output of 10A, that's why I've made a module that combines the TP4056 with a 10A BMS at the output.

I prefer to use USB type C Power delivery feature to get higher voltage for 2S/3S/4S instead of boost converter. & also TP4056 is just a general purpose IC for DIY projects. I suggest using CN3795 IC, a multi chemistry, Multi cell battery charging IC including MPPT for solar charging. In combination with normal BMS, this system can literally charge any type of battery pack with USB type C.

Thank you for reassuring me i am not crazy. I was looking around Ebay and Aliexpress for a 2S Charger together with a BMS Circuit. Exactly like you stated, it was either a charger without protection or a BMS without charging IC. I thought I was too dumb to look for the right parts, but now I'm glad someone else has the same problems finding a suitable module.

This is exactly the education that I need to understand projects involving high current and 18650 batteries. Thank you!

[pawelutwin]

finally someone explained it to me. This is what I needed. Looking forward to seeing material about BMSes

[nextmove]

This was SO helpful. I was looking for a power system for future DIY projects!!! Thanks for this!

Yeah, perfect timing.
I have also been searching for this type of board and saw that they don't exist.
I needed a high-capacity ultra-quiet 5-volt (USB out) battery module. So I opted for a 2S-4P battery configuration with a buck-converted output.
I had to piece together different circuits to meet my needs. It is very cumbersome with three switches and a battery level indicator to ensure I don't over-discharge the cells. Since I didn't include a boost converter for the charge source, I am using a 10VDC wall wart.
The first switch is the charge/output switch to route my 10VDC charge source to the 2S-BMS. The second switch is used like the on/off witch. It is part of the DC input plug. When the wall wart is disconnected and the charge/output switch is in the charge position, then the batteries are isolated and it's essentially off. The third switch is a momentary switch used to activate the battery-level indicator so it will not drain the batteries.
What I feel there is a need for is this and I would purchase them from you today:
Fast rechargeable, high-capacity battery packs with USB output and adjustable DC sources. It would be nice to see the battery level, the output voltage, and the output current with a simple push button.
The output should be a low-noise DC voltage from a linear regulator. It could be also current-regulated for the ultimate version with an optional fan for cooling.
The charging voltage could be from two sources. A high-current fat charge could be from a wall-wart and a slower low-current source could be from a USB port with a boost converter to match the 2S or 3S configuration.
I think if you built a board with a choice of 2S or 3S configuration options, you could sell thousands of these boards.

Also most type C PD charger will output 5v, 9v, 12v and 19v{or 20v}.
With this you could use a PD type charger and avoid a boost.

[alexnewton]

Brilliant idea man. Good job and thank you for sharing. I will try your PCB

[johnshaw]

I bought a 10A strip 1S BMS and then connected it to a USB-C charger module for USB PD and a protected 14 AWG 2.5 mm DC jack output on a broken 30, 000mah powerbank to repair/salvage/upgrade it.

Thank you for posting this, I was looking for a way to charge a 2s setup via 5 volts usb, but I couldn't find any modules.
From the looks of it it's going to be a component setup.
You made a new fan today, thank .

18650 cells can also have integrated BMS boards, they mount on top of the negative end cap replacing that connection.

[MitsuZerG]

Just what I was looking for yesterday! Thanks for the video!

[ronniepirtlejr]

I have 38 of the Panasonic NCR18650B batteries. Awesome batteries!👍
The spec sheet says they can only discharge 15 amps "continuous" safely!
I just thought I would mention it to you since you were showing a picture of this particular battery with a discharge rate of
20 to 30 A. next to it.
By the way you know way more about Electronics than I ever dreamed🙂👍

[DEPITY]

the best method to trick the module is to connect the negative output to the negative side of the battery that way you can use the module at a higher current output it won't trigger the current cut off but if you know what current you are handling and is pretty much 125% than its designed output then it is good to go

[californiakayaker]

I am in complete agreement with this. My system was originally built with DIY BMS Equipped Cells 3.2v 320ah. x 4 and I've done really well with them. I'm now up to seven of these for a combined kwh or 25, 000 . So, some have suggested that I might be growing out of this system. But, I don't need a high powered inverter and may never need that, in fact, as I continue to evolve my system I need less 110v rather than more. A more typical inverter can supply my needs . The big need is for storage of energy. That need is present because of the fact that I rely on solar, and in the winter I'll have times where there will be up to a week with little solar. !2 volts if great for me. Thanks

[sinisterkage]

I'm so grateful for your work. Keeps me going on my projects

[kikihun]

Check out the 12v ups switch modules too. They are pretty cool, can switch to wall power if the battery goes under 10v.
Pretty useful for a constant running Rpi server on a solar system.

[jaishankarm]

USB PD can delivery upto to 20V 100W. USB PPS allow us to custom voltage and current output limit.
Can you please try this method also??

[prakashdutt]

Hello Sir,
Can I charge 3s and 5p battery pack which is around 11.1volt &10000mAh with 8:52 chargers like this directly connected to BMS?

Or do I need any other module in the middle of BMS and charger to get my battery charged?

BMS----> charging module---> Charger

[mavic-mark]

Did you ever have any made and tested ?
If so will we be seeing a video?
