PLS send my stl file, THX ..., Does anyone here have it, stl? Can you forward it to us?

Lets hope that you did not become an engineer otherwise the western civilizations is doomed.

U r great sir ❤perfect solution

Older roombas have an intelligent NI-MH charger. If you put in a Lithium oack instead you DO NEED a BMS!

Bro 96 bms and around 15A of parallel charger to maintain the batteries wont heatups

Thank you

Is it safe to use with cells of unknown historic ? I need to repurpose thousands of powertool 18650 cells, how can i determine safely the capacity of everycell ?

THE USB EXTERNAL POWER CORD FRIED MY LUMIX DMC-G85 GET RID OF IT AND USE THE A/C POWER SUPPLY TYPE.

Disculpa a qué cargador o adaptador conectas los cables principales

👍 Please fix my Roomba too😢

ฝรั่งทำบ้าอะไรวะสร้างเครืองชาร์จตั้งเยอะมากเกินไปเบือเสียเงินมากเกินไป

So you buy it and then drive it like you have before. Are you in the interior of BC?

Did you use the factory charger? Dont you need to use something else like an RC charger that will give CC and CV ?

full support tamsak always and bananas to this awesome host

any stl for your battery holder?

One thing I’ve noticed is when the powerbank gets to a certain %, the camera is no longer able to take pictures. I have an Anker 10,000mah powerbank and when it gets to around 50%, the camera shutter stops working. It kind of just ‘thumps’ and doesn’t complete taking the picture. However the camera can still remain on, it’s just unable to take the image. I’ve had the same problem with my 5000mah Energizer powerbank - seems to stop taking images when it gets to 25%. I wonder if the current from the powerbank changes as it drains and doesn’t give the camera enough power to take the shot?

@Havin'Fun Can you share the stl files for the 3d printed parts?

3d file please

Hi... I've a asking about the BMS/PCB. The version is 4S 40S? Is that correct?

That's what I felt like building.... Worked out that it would take 25 days 24hours a day to charge most of the cells. I ended up making a 8/16 cell charger. Small and portable! But... Down side is that the tester is only 4 cells. I could have got more of the testers, but the pack build is 'for fun'. I'm 3 weeks in and wish it was new cells. Then it's only charging that's needed.. Mine will be a run away, don't do it video coming up.... Good ideal, but you don't need the monitors as you can manually do it... I'd have some volt meters on there so you can see what's going on.

Great tip mate thank you very much. Great moustache too.

How to solve the error 5 when charging?

nice work, quite professional, whats happened to your videos? no more vids? link to bms board source would have been good

Cool way to set it up. I was thinking something like this as I have a 600mm camera lens, and with a working mount and a OK scope I should be able to work the camera to position. The eclipse is interesting, yet is likely not what was come to understand of it. There have been solar eclipses recorded in history with both sun and moon being present across one another. As for that piece to mount the camera, I would surely use a piece of metal to grind down and fit to adapt, not plastic, specially if you want it to last with confidence. As you already know, but fun to be able to do it on a 3D printer.

Its interesting how you watch says you started at around 3ish O'clock, and then ended SOONER at around 1:53 !!! Amazing speed, you made time go backwards! :-)

Well done! Wish you didnt speed up at11min, but thats oK...I think I got it(even though you changed that setup)! LOL

Wow! this was amazing to watch the design process. I would change the title of the Video to include [BATTERY DESIGN PROCESS]. maybe you'll get more hits? I also really appreciate your talking thru hazards like heating, follow up testing, welding, watching for puffs of smoke :) I would have liked some more talk on how the BMU works as you were building (thinking a head while you build). I've never seen a home spot welder before either... it's going on my Christmas list :)

The proper method of setting focus to infinity on an AF lens on any Micro Four Thirds is to press the lens release button once - don't twist the lens or anything. This is part of the M43 standard. I'm afraid your methods are a waste of time.

Hi, what's your wire size? is it 10AWG? can they do 96A?

Curious how this went long term? From what I have researched the XT connectors are rated at max amps and they should run at 50% constant load.

Something cool about the large pines covered with snow

Excellent tip on the infinity focus after shutting the camera off. Does this work on the G95 also ?

nice video

how much voltage drop do you realy have at the end charger kabels . i think there would not be 5 volt anymore cause if you charging witch 1 amp your using 96 amp . or are u charging with 500 ma

Hi How can I charge the 7s power wall by a charger, however all chargers in the market are 24v and I dont know if its voltage reach to 29.4v.

Fernando M. hace 33 minutos (editado) The problem with the old Roombas is that the firmware is not prepared for the lithium charging parameters and they normally end up with Error or some worse: charges but damaging the Lithium batteries. In fact once the charge is completed, a 50 mA stand-by charge (know as 'trickle charge') is applied in a continuos cycle between 40 (start) and 42 ºC (stop) intended for typical Ni-MH self-discharge, wich for Lithium should not be applied cause is hamful. In fact Lithium batteries have not worked for me neither in my Ni-MH old 560, 531 or 650, in some cases due to Error 1 or 5, and in others it apparently worked, but the battery died after only 6 months, which implies an enormous 'mistreatment' in charging (probably after a a lot of hours of damaging tricke charge), because an original iRobot 1800 mAh lithium battery must live at least 4 years (my 671's one only lost 15-20 minutes in this period after 2000 hours of use) ... I confirmed asking about to iRobot about and was confirmed, Ni-MH for Ni-MH Roombas, and Lithium for Lithium Roombas Good luck!

Paralel tp4056 w/ balancer just make you big problem, input negatif is not individual, its linked...

hello yes it is not easy to solder on the screen it looks big but in reality it is very small to do and it is better to be good with your fingers some videos in general from asia do this quite easily i wonder how they do it and with very low quality material... i already tried with pcb boards seen on youtube but it's too hard to connect.. .

how mny hour you charge the battery. how about the current

Hi

M

Quan trọng có bị lỗi sạc k khi thay pin litium

This looks awesome you did a great job

Nastima is actually selling a product like this with bms included.

I was going to do the exact same thing for my roomba. Thanks for sharing.

i learn this from uu tq.. bro

Hey can you tell me the name of that device that gave you the amps output?

I replaced the old Ni-HM battery with a Li-Ion battery with BMS, and now the iRobot 780 vacuum cleaner doesn't recognize it when charging. Error 1, what to do with it?

Very useful video for li-ion cell charging in bulk quantity 👍

It looks awesome man 👍 I'm still testing my cells xD
