Imagine when he discovers esp
Alex did a great job and is running your business will you share his findings??
Ha I love it imagine if he starts up a raspberry pi monitoring system
I'm watching too many Jehu videos - I'm now saying 'All right!' before it begins! 😂

The ESP8266 board would also give you a Wifi connection to read all of the data you are logging.
Or ESP32... for Bluetooth but hard to program
Hey Jehu, you might try an ESP8266 board for PWM with 3.2 volts. You can find them with the usb connection.
Ill be buying 40 of those packs for an off grid setup in the near future. Would be a nice reassurance to know how to set it up for multiple packs. Even if its just a signal booster on a bus.
Pretty sure you can use the nano you have to flash the pro mini. You load a piece of code on the nano and it creates a virtual serial port, you connect the pins from that to the pro mini and it does pass thru flashing. Works with the uno, should work with the nano.
Kind of but since his nano is 5v and his pro mini 3.3v he needs to run them both at the same voltage
All I want for Christmas is a pair of the Jump Scooters!! 🛴
Free batteries on the street corners, you just have to block their radios. Throw them in a metal box or large anti static bag. Those lime and bird scooters are like sidewalk barnacles.
*I don’t condone stealing or damaging private property despite them being greedy and opportunistic and blocking sidewalks and handicap ramps with stupid overpriced scooters
how about the esp 32 it runs both 3.3v or 5v they are pretty cheap lady ada at adafruit will know
Put a thermal camera on them for us.... Curious to see the heat distribution....

Je možno to koupit
For a simple pulse why aren't you just using an attiny 85 w/ an led on the tx to drop the voltage? or an esp32 if you want to send that telemetry somewhere?
@MrGarcia... we can hear the excitement in your voice , let’s wake these bad boys up...for those of us who purchased a few batteries that came with out the cut connectors.. do you know where we could find them?
I ordered a few thousand, they are being made in China right now
You can program a second arduino with another one. The First one needs an USB connector, Just search online...
You can get a 48+volt to 5-Volt (adjustable) buck converters on Amazon and eBay for a few dollars (LM2596HV)
Sweet! Time to buy some packs!!
Hi there! Make a video with Xiaomi m365 and 36v 7800 ah and pro 12800ah
There is a loot of this batteries outside that can be used!!😜
Great video!🇬🇷
I bet someone could do it with a nodeMCU 8266. It has a 5v in and a 3.3v out.
And use Blynk to monitor the battery on Android or iOS
@@georgidimov4353 I thought "blink" was only a output code?
I bought a scooter at an impound auction, but it is turned OFF. The battery seems to have enough charge. Does anyone know where I can get a schematic for the whole scooter?
You can have a simple voltage divider to go from 5v to 3.3. You'll need just 2 resistors - 1k and 2k. You need only 1 divider from arduino to battery. 5v Arduino will be able to read 3.3v signal as is.
Most likely for this uses there won't be any issue but it can cause noise with fast signals, it would be better to use a level shifter or just run the Arduino at 3.3v(this voltage it's not within specifications for 16mhz clock but it most likely will still work)
@@hennochoi yes, absolutely. I'm running such divider between arduino and BT (hc-06). Works very stable at 9600. But l would not go with divider for higher speeds.
You can use the nano to program the other arduino without the USB. Look up the Arduino as ISP sketch
I don’t know how to do that
@@jehugarcia www.arduino.cc/en/Tutorial/BuiltInExamples/ArduinoISP/ Here's Arduino's tutorial. Here's another post that outlines how the pins should be connected (i think these are the boards you have): arduino.stackexchange.com/questions/23934/can-i-use-arduino-nano-v3-to-program-another-arduino-pro-mini Without knowing about the mini you have there I'm not sure the voltages match but its worth a shot.
@jehugarcia you could use attiny85 dev board instead boards with atmega328p-au, as it is much more cheaper.
That’s pretty sweet. Would a small switch that cut power to the mini converter let the battery turn off ?
I have a arduino nano 16mhz (5v version) , can I use it with 3.3V DC-DC supply without mod ?
found you on forum! but this one is not new, guys from company called "scooter-unlock" has this since few months. Complete kit with power step down and case, few bucks more though but works great.
Can’t find scooter-unlock. Is it in us? Thx

Hy,from Rumenia country..

THAT ARDUINO NANO CAN RUN FINE AT VOLTAGES AS LOW AS 1.8 VDC...
Remove the on-board voltage regulator ans put a jumper between what would have been the input and output pins of the voltage regulator, and power the Arduino over the external power port from your voltage reducer.
But program your Arduino first over the USB connection to get your program into it, but after that you can remove that USB socket if you want because you will never need it again unless you want to modify your program some time in the future.
You will probably have to run the Arduino at whatever voltage your battery pack controller likes to run at...
You can probably do everything you need to do with an ATtiny 85 part!
YOU CAN ALSO REPLACE YOUR DC TO DC CONVERTER WITH A 3.3 VOLT, (OR WHATEVER VOLTAGE YOU REQUIRE), ZENER DIODE AND A RESISTOR.
THAT IS BECAUSE THE POWER DRAIN WOULD BE SO LOW IF THE ARDUINO WAS NOT LIGHTING ANY LEDS AND ONLY COMMUNICATING DIGITALLY WITH THE POWER PACK, IT WOULD NEED VERY LITTLE OR NO POWER TO DO THAT...
.
i APOLOGIZE FOR THE CAPS LOCK.....
Arduinos used to activate feed for chickens while I was working on the on the road.
I used one to open their chicken door to the yard for years - until... I was gone for a couple of weeks and my dogs were at my ex-wife's house. The coyotes just waited for the door to open then proceded to eat all but one of them - around 40 chickens over a two week period. Yes it was a bloody massacre! I gave the lone surviving traumatized little hen to my friends mother.
if you have to ask yourself if youre in winter, youre not
I got the preprogrammed arduino and i see a faint TX blink, but I'm unable to get anything more than 3.x volts out of the discharge port?
The battery is charged at 41.8 volts, but im only getting 40.6 volts out of the P+ and the ground pad right above it (*not the P- or C-)

Aw common i would love to have these packs for my new Build but once again it is USA only ....
:( my light isn’t coming on when I plug the dongle in. Do I need to give it some juice? I can’t find that video where you plug a wire into the plug hole?
That's alot of COOL!
Damn you have a awesome lab I'd love to work on some things in there with some of the supplies you have
What do you think of the new Tesla battery he just made
yay! can't wait for the dongle. Would one dongle be able to charge multiple batteries at once/together?
Watch the video please
Can I buy the unlock units you make? I am using salvaged lime/Uber batteries in sets of 9 for my hybrid drive on my Kenworth. I I can use one per 9 ease advise so I can order the correct amounts. Thanks, Charlie
Hello. I am from romania too
Technically....... winter doesn't start until Monday.. :-)
Can you charge the batteries with a 42v 2a XT90 with the dongle?
Yes
can you please tell to battery hookup that they need to have an option to ship their battery's to Indonesia?
cool video man sitn next to my 8s1p rt now 3.7v funn
Would the BMS shutdown once it is full if you charging via the discharge port?
It’s its only job
@@jehugarcia I guess to the point you made in the other video there doesn't seem to be any real benefits to using the 5A port over this then. Awesome. Going to pick up 4 more now. Thanks. :-) The two I have been working pretty well.
@@jehugarcia So I do not think the discharge port disconnects when the BMS wants to stop the charge. It seems to me on the batteries I have that only the smaller charge port disconnects and stops the charger properly. Putting a 12s charger on the discharge port it seems to allow over charging... but maybe you want to test that on a pack and see?
@@longle7603 Until confirmed I would suggest you stick to charging over the charge port only if you want the full BMS safety... I have 4 of these packs and mine do not disconnect when over charged on the discharge port but they do disconnect the smaller charge port at about 42v properly.
@@jontscott Interesting, With my testing with 2 packs in parallel. I set my Power Supply to 41.98-42.00V. I hooked up a watt meter to it and found that once the battery hit around 41.95-41.99 the amp draw is at 00.00. I then tested with my 42V 5A scooter charger to the discharge port and once it hits are 41.95-41.99 the light goes green.
Why you Don't use a Lm7805
Maybe a dumb question...how do you charge these scooter batteries? Can you charge through the discharge cable or only through the smaller charge cable?
It's like jumping a car. Battery to battery.
You are so smart!
I want a big battery bank for my home solar project
Winter isn't until December 21st
Quick question on the PCB Kit ordered from you. Is the PCB board the same for both the High power 2C and 1C just different battery holders?
Yes
Question: So there is enough power coming out of the battery pack to power up the Arduino? No need to jump start it from an external power source?
Watch the other video I did on these, I explain the full behavior of these
Hi Jehu
Have ordered products from you through a friend in ther U.S. Other then batteries will you take orders from Canada? PCB's are what I am interested in. Tried to buy on JAG35 but no option to buy from Canada.
Too many delays, packages lost, too many chargebacks i don’t wanna deal with international shipping right now
Now the question of the million dollar. Is one ard nano enough to drive multiple packs! or you need one arduino module per pack. Thanks please advise
No you can drive multiple packs with one signal.
@@jehugarcia thank you mr Jehu 👌
6:23 - Those two batteries were not connected directly in parallel, were they? The device in between was regulating the charging I guess?
It would indeed have been dangerous to connect them directly in parallel because the self balancing current with a 12 V difference (42V vs 30 V) would probably have reached above 200 A easily
200A! Prove it. I just showed you the max it reached was 17A and immediately starts tapering off.
@@jehugarcia so that’s why I assume you used a charger in between, that device with the screen??
If you would have nothing in between and a voltage difference of 12V, and an internal resistance of the packs of approximately 0.050 Ohms, according to Ohms law you would get a current of I=12/0.05=240A
I mean this is the same reason that you should always have the same voltage of cells or modules that you want to connect in parallel, otherwise the self balancing current will be too large, going outside the spec of the cells.
Numbers on paper don’t always work in the real world
@@jehugarcia with all respect, but they do. The only reason would be that your packs have a much higher internal resistance than my assumption, or that the BMS has a limitation function of the current that is kicking in.
Or that the voltage difference was much smaller than my assumption.
The reason I am pushing on this is that I don’t want other people to connect unprotected modules or cells in parallel that have large voltage difference. That could be very dangerous or abusive to the cells.
I work with batteries since 10 years, so I promise you, I’m not making things up 😊.
Anyway, love your channel, great stuff 🙌🏻
Did you see jack Rickard connect the 2 Tesla packs together? That was a full size experiment of this cuestión
Can someone please link what the custom connector is called or somewhere I can source some? Jehu is sold out of the connectors and dongles on his site.
Would it be possible to build a power wall in a camper so it can go off grid for a week?? Would have solor panels on the roof but want to build my power supply into a roof box to save space on the i side thanks guys
Of course it would...
Batteries don’t like hot and cold, you’re going to have to sacrifice some corner inside to keep your batteries temperature moderated.
Thanks peter 👍🏼👍🏼
Before diy (witch is cheaper most times) look for the Bluetti AC200P (or smaller models) I don’t think you could get it relay any cheaper if you diy... Solar charge controller, inverter...
Will go have a look tim 👍🏼👍🏼
You have to use 1 arduino per pack?
Anche per il modello es400 ?
So the battery will charge without the Arduino? But need Arduino to discharge?
I think that the management circuit in these batteries can track charge rate pretty reliably and safely but the discharge thing could be a safety thing in case of a short or to help manage battery drain. Those are the two things that come to mind.
Correct the bms will stay on if it’s being charged but will turn off after 5 seconds if it sees a load without the serial signal
ur store says those batterys are sold out , are they coming back ?
Yes that was mistyped link
kinda cool arduino IDE is difficult
Hi Jehu. I've been working in decoding the bms serial information too. Can you put me in contact with the other guy that is working on it?
His name Alex graeda, same person that made the MegaCell charger and redesigned the electroDacus
@jehugarcia hi, I've noticed that when batteries are dead, even if charged over 40v before..., the arduino signal won't wake them up! It is necessary to wake them by charging them at least a few seconds thru the low amp charge port. Has anyone had any luck in walking them in a different way??
@@MonbogDecan yes you are correct, when i received them all 3 packs showed 16V output, however all cells showed 3.4V .
So obviously the pack had shut down. Was able to charge up to 42V , but still no output to load even with sending serial commands. So i applied 42V to charge port of pack for a few seconds then battery woke up
Yeah I’ve had some trouble waking them with the arduino I got from Jehu. The packs are charged up to 42V now, but still no luck waking them when connecting the Arduino to them and trying to get power/load from the load side. I may try to go through the charge port side and give it some power to try and wake it
@@christianperi apply 42v to charge connector for about a minute that should wake up load side. Make sure no load is connected, only your volt meter to verify.
Use xl7005 board
How many of these are needed for making a 50kwhr power wall? i use 40khrs on driving in 1 day of 150miles round trip. Bolt Ev 2017.
Where do you get the screw on battery connector? I can't find it anywhere.
Look for phantom mic connectors

Can’t find the screw on ones just the plug in type thx
Do we have the code to get those nifty values yet?

All of them, just don't lick the terminals
@@iforce2d well you must have a Volt limit on the mosfet? No?
100v mosfets so probably 2 for 72v, I will eventually experiment, 30s would be enough for EV use
@@jehugarcia can't wait to see that, thanks!!!
@@jehugarcia wait did you mean 3s for the 108v ? 30s is like 1080v haha

These DC buck converters seem to be a lot cheaper than what you're using in the video - www.amazon.com/LM2596-Converter-Module-Supply-1-23V-30V/dp/B008BHBEE0
But they can’t handle 42v, so not useful in this application
@@jehugarcia they go up to 40v is that not within a threshold that would work?
@@JeremyWhittakerAZ The packs charge up to 42v and I think the ranges you would want on a 36v system like this would be up to 45v for safety.
