I like how you keep touching it while it's on just to show it's safe

[@Delali]

No its not safe to touch.

[@fawazmaiyaki7512]

@@Delali well you touched it with your bare hands more than once so...but I get you bro

[@AyushSharma-ss5hj]

brother you are doing an awesome job, your videos are so awesome.

[@Delali]

Thank you so much🥰 Wish you all the best.

[@makeful1]

hey nice video. what kind of circuit breakers you use on this set up? link?

[@Delali]

Thanks so much. I used this kind. you can select 2A and 60A. s.click.aliexpress.com/e/_DFhNfJl

Amazing work.

[@Delali]

Thank you! Cheers!

So code has to be written and uploaded for each of the battery charger?

[@Delali]

Fortunately there's no coding needed.

[@calebcadainoo]

@@Delali oh ok

The boards are not computers, they're just cheap modules.

[@Krzeszny95]

Pro tip: it's bad to keep lithium batteries above 4 volts even for 1 day at a time. They deteriorate when fully charged. Ideally, they should be charged right before use and discharged to 3.7-3.8 volts after use. Pro tip 2: when charged only to 4.1 volts, lithium batteries get 2 times longer lifespan. When charged to 4.0 volts, they get 3 times the lifespan. Unfortunately, TP4056 boards don't have programmable voltage. Your friend's UPS modules could charge the batteries less than 4.2 V to increase battery lifespan.

Thanks for the constructive feedback fam. I really appreciate you taking the time to leave your comments. As mentioned in the video description, i posted the video to learn from my viewers to improve our next build. Therefore I'm very glad to learn the insights you've shared.

[@duronboy2]

What charger does have programmable voltage?

[@GHizmoHub]

Impressive!! Learnt something today☺️😅

[@Delali]

Glad to hear that! Cheers.

[@SodiumInteresting]

you should discard or re wrap the batteries that have damaged covers. they can arc

Thanks for the feedback good sir. Much appreciated. Please don't forget to subscribe. Cheers!!!

Great set up!! How are you testing capacity of the cells? You say not to overload the power supply, but you're drawing 80A from your 60A power supply.

[@Delali]

The friend i built this station with got a capacity testing unit later on. I believe it was one of those Chinese builk discharge types. No, even though we had 80 cells in the racks at the time of filming, alot of them where well around or above the 3.7v and as such did not all draw 1A to make 80A. Also my friend Samuel got another power supply for the lower half of our build later. Also we had more cells available to charge, but as seen in the video, we left alot of the racks empty for this same reason of not maxing the power supply unit. We wanted the whole board to light up at least, to show what a complete working unit for 150 cells will look like.

[@bushratbeachbum]

@@Delali ah ok. So no capacity testing on this rig?

[@thonynart4640]

WOWWW...

[@Delali]

Want to build one?

[@RichardAdarkwahgh]

Awesome

[@Delali]

Thanks for the time fam.

hi, I want to make a balance charger using tp4056 for 48v battery 12s 3p does that mean I need 12 tp4056 modules connected in series and then to the battery like BMS wiring?

[@Delali]

Unfortunately the tp4056 module doesn't work that way. To the best of my knowledge it charges only one battery at a time. So the batteries can't be in series or parallel connection. To charge your 12s3p pack you need a 12s BMS connected to a 50.4 - 53v DC source. Each of the batteries in the pack will be charged to 4.2 properly and any excess will be damped by the BMS.

[@steveshea6148]

If you trickle charge the 1.6 volt low voltage batteries , i.e using a lithium metal hydride protocol at 0.1 amps, they may come above the threshold voltage for the li-ion charging controller to recognize it as a chargeable battery. However they still may not perform well.

[@Delali]

That's an amazing insight. I will keep this in mind for later. Thanks for sharing buddy.

[@Shubham-9996]

Do you give away battery

[@Delali]

Unfortunately not, my friend builds UPS's with them.

[@fawazmaiyaki7512]

But what actually are these batteries going to be used for in practical real life use?, I mean, you're charging batteries and we've seen that, but we want to know what we need the batteries for before charging them up

[@Delali]

The friend you saw measuring the voltages of the cell builds UPS's with recycled batteries. So he asked me to help build a charging station to help process the batteries faster. I decided to film the station and explain what we did. Hopefully I could learn something new form my viewers on how to improve the next build.
