How to add power meter to ebike or battery? Q&A#2

[@mikeg6633]

I'm new to ebikes. I don't like peddling a regular bike because I can't ever stop. Your videos are always a great source of information. I've built my own ebike out of a kit, but that didn't last long. Now I'm waiting for my Totguard 26", 500W, full suspension ebike. I chose that bike because it has a very heavy frame and I plan on upgrading it. I reference your videos a lot to prepare for the project.

[@marydepuydt7291]

HI just watched your video on installing a watts meter on a ebike battery. great video but wondering with this setup will the meter show the volts in the battery to indicate the power level/fullness of the battery. The power bars on bike monitor don't really show to any great detail if the battery is full or empty. Just wanting a more detailed answer and hoping your method would show me. Thanks in advance Jim

[@castuyn4618]

That CA looks very good, but can it drive a retro-looking round speedometer and round 'fuel' meter (0-100%)? They will be easier to read and look better on my electric cyclekart I am building. I plan to use 48V batteries with 3000W motor so will draw 65.5 A.

[@brannenthompson9662]

The cheap watt meter is a briliant buy it tells me loads of info I would have never have known otherwise ie my amps and best of all my ah and voltage in real time , thanks so so much for this video.

[@truhunk1]

Brannen Thompson . So does it show you the amp draw ?

[@TrackdayDaddyPH]

Hi.. do you know what is best type of wattmeter/amp meter for a 72v battery pack? I purchased a digital analyzer but it is only rated up to 60v DC.. thanks in advance.. you have nice videos on ebikes

[@ucanoe]

I'd like to know how to test the health of my battery? any good videos on that?

[@gursisingh1940]

Can you add a cycle analyst ALONGSIDE the display that is already on the bike?

[@VaultBoi101]

Do you have a video of using the cycle analysis be connected to two motors im looking in to doing that myself

[@thingsandstickers4368]

thank you ! Can cycle analyst store or log the capacity along the way and that can be recovered in a flat file ?

[@darylogle6696]

If your bicycle does not come with a display do you need to get a new controller to add a certain type of display I like the color one

[@cycleguy417]

How does one determine the serial/parallel configuration of a battery pak?

[@ronaldrodgers386]

Thank you for your video. How do you read the watt meter? I really enjoy your videos! :)

[@JohnKimble-v6l]

How to add 110 AC to a 60V battery in a EV Scooter so I can install Nest outdoor security camera with iPhone app?

[@truhunk1]

Very good. So I bought one of those Yeeco digital amp/volt meter. It has a shunt as well. I now think it can NOT be used on an Ebike because the controller messes up the hook up connection. Am I correct ?

[@henriquecosta2043]

hello micah, browsing on aliexpress i found this device... , the idea was to just run a few small gage wires to the display in the front of the bike instead of the power wires , it works great and even has over voltage,amp,watt and other things protection through a relay, there are similar devices that even work wireless... , i still can't get a total ah wh because it keeps reseting ( the manual translation from chinese is terrible), but i hope that there is a way to prevent that...., the protections turns the relay on and i think that to put it back off it has to b done manually .... anyway maybe there is one of these things that work well and its only 16 euros....

[@RobtAWhite-gz3jb]

I enjoy watching your videos (diy e-bike projects). I have a project bike, I started a month ago. I have a 1000w brushless motor in the rear, and got another one for the frt. drive. Question: can a 1000w brushless motor be turned into a generator? If so, how do you wire in. Thank You for your time you spend on my question.

[@Bigrignohio]

I assume a wattmeter would be an easy way to determine total battery capacity when using an inexpensive BMS with a discharge setting? Also has anyone had issues with the typical wattmeters (rated 0-60V) on a 14S system (58.8V)?

[@2-da3333]

this may sound stupid, but what's wrong with the battery meter included within ebike lcd screen ? why do I need this ?

[@mick2d2]

A lot of them (I have used the BBS02 with the C961 and the BBSHD with the C965) are not very accurate. The methods he mentions give you accurate detailed information on Watts, Amps, Wh etc. I used the first method he mentions with the BBS02 and then changed up to the Cycle Analyst with the BBSHD. Were it compatible with the Bafang (it isn't unfortunately) it could replace the C965. As it stands it gives you accurate real time and average info on every aspect of power usage and also gives you a very accurate "fuel gauge".

[@pronutritionmaroc9772]

Hello Mike. When you start talking everything become simple but when i'm in front of the motors all get complicate. Please i need some help. I have two motors and two controllers, all the same. (72v, 3000W).Is it possible to connect one throttle ,one lock key and and lcd screen with speed and batteries indicator for both controllers(motors)? Thank you for your time.

[@vaughnwalker1840]

My question is can i wire a smart shunt to an ebike battery pack,?

[@JessicaRyan7of9]

Dear ebike school Witch would be the best motors to have. A wheel hub style motor or one that goes where the pedals are.

[@FretsNirvana]

Thanks, if you put one of these in line and had a load drawing on it then reduced the load would it then give an amp peak reading for the maximum load that happened? I want something in an r/c environment here I can monitor the maximum current draw under load.

[@Shane-zh6tx]

What steps do you take for battery safety?

[@rdkuless]

Can the GRIN Cycle Analist be used with a Bafang BBS02..?

[@abutlerish]

How about dual separate motor kits one front one rear 2 separate batteries and controllers independent of each other

[@danielseifert3309]

Q: I have a DYU D3 (250W motor. 36v 10.4 li-ion). Can I upgrade to a 48v 17.4 li-ion battery pack? How does a more powerful battery surge translate in terms of pace/speed? It will give slot more distance, that's for sure! But worried about the motor and how it would affect it. Bike set at 15mph on 250w.

[@kalilkibab]

Question: How come no one is using LYPO batteries, the ones that people use for high speed racing drones that provides power up to 30A, yet small on size and high on voltage instead of 18650 cells?

[@hardergamer]

Fire risk.

[@greg23842384]

Haydar M. 18650 are also more energy dense and you getore cycles out of them I personally use lipo and 18650 on my ebike

[@Poepad]

What is the best soldering station, too many choices out there?

[@justincash6037]

Hi, I’m wondering if you are familiar with the amazing Juntek shunt power meter. I’m doing a ebike scratch build and want to use it for controlling and monitoring my system. The unit is only about $40 and will do 100amps The display unit is also wireless from the shunt.

[@ebikesolutions500]

If the display is wireless it won't be able to read the amps voltage

[@markpugh6157]

I have a e-bike and it's not taking a charge at charges but when you put it back on the charger it's dead as Dead as that is a door knob.

[@ucanoe]

most ebikes have a display with bars showing the remaining power? why add power meter?

[@WillDailey84]

i have a 500 watt motor on a 60 volt battery and when i add one more battery the bike will power on but will not move...so i then take the battory out and drive the 60v hard for 20min then hook the 6th battery up and it seems to work and the bike is 20 km faster please help

[@arjunsokhi3677]

Hello I have a question for you, can you wire an extra battery to the ebike kit to provide more speed? I hope there is a way because I want to keep my existing battery but have more power, kind regards

[@ituneca1862]

Change controller for a high amps one.

[@petertothRC-FPV]

hi thats a great gauge to manage your system. i have been looking at lots of ebikers out here and lots of info for all kinds of things.my 48v bottle type battery is showing that when the switch is off 11-12v on both the charge port and output connection.when the switch is on both are showing full voltage.i have 2 good batteries that i have managed to keep in good shape.and 2 that are in bad shape i did not manage.they all read the same way.can you please explain this?there must be tons of these batteries in use but i dont see much info.

[@berendlensvanrijn386]

hi, i have an e-bike and also an electric boat with trolling motor. I have a question regarding knowing how many hours my electric trolling engine has run. This because it needs servicing every 100 hours... can you suggest a solution?

[@llamudos9809]

hi I have built my own ebike and battery packs but have a few cells that are unbalanced. 54.6v 13s 8p 2200mah/cell approx. 17.6ah. I have bought an imax charger but its only able to charge/balance 6s at most is there away of balancing safely my 13s pack without splitting the cells to 7s+6s pack?

[@ebikesolutions500]

How many watts is ok to run threw my 1000w motor

[@ahmadqujo1697]

I wanna add a usb port to my 48V battery to charge my phone is that possible?

Hi bro.can I use 72v 20ah charger to a 60v battery thanks

[@dentvofficial1128]

No can damage ur battery

[@yogeshnaik9276]

Very nice information i was looking for as am in India i cannot buy one easily...however i have imported collection of Bafang mid mount motors

[@danjarrett]

Hello. Love Your Videos. Very informative and Nicely put togather My Question is. Why You Build Your 18650 Packs in the way You do instead of Building a Testla Style Pack that Has individual Fuse's for Each Cell. I'am getting ready to build a 12 Volt Pack out of Used. Reclaimed Laptop Batterys and I decided to go with the Testla Style Pack so I can have those Safety Fuses for each Cell incase something Stupid does happen with those Used 18650 Cells. Just wanted to get Your Thoughts on that Idea. Thanks so Much for Sharing all the great Battery Info. Dan..

[@hardergamer]

Why don't them laptops use them?

[@adrianthorp4341]

what will happen when a fuse does go? the remaining cells in that parallel group will have to take up the demand so while the cells were quite happy draining at 1C, if you had 4 cells in each group you will have 1.3C making the rest of the group work much harder. Tesla have a LOT of redundancy built in, they only charge to 80%. that being said if you build the additional capacity into the battery then its a great way to do it as the parallel groups don't see a lot of amperage, that's why the fuses come of a large series connection. But comparing custom built cells at Tesla's design to random used unknown capacity laptop cells is not exactly the same thing, if your determined to go that route make sure removing and replacing dead or exhausted cells are easy.

how to make 24v ebike Lithium battery please make a video

[@prathwishmestha7224]

Hey there, how do you know the battery status of your ebike battery pack? Like how much charge is remaining in the battery pack (in percentage or Ah). Thank you.

[@SandwichMitGurke]

your videos are very helpful!!

[@bert8807]

why do I need to know my wattage when I ride my e bike?

[@EbikeSchool]

Mostly for fun.

[@bert8807]

Ok I can dig it. But I'm a little too old for that kind of fun.

[@reddelatorre]

very informative !!!

[@charlesmost6493]

PLEASE MAKE A VIDEO ON HOW TO DIY EBIKE 18650 BATTERIES INSIDE AN ALUMINUM REAR RACK BATTERY BOX. I CAN NOT FIND ANYONE WHO CAN ADVISE ME OR HELP ME TO BUILD THIS TYPE OF EBIKE BATTERY. CHARLY

[@tejasdevlekar9231]

Sir please make electric cycle with 24v 250w moter and make it self charging battery

[@marciaz31]

Wow Mike you are everywhere ;-)

[@brianmi40]

Since my DIY build is a 36v system, for basic info can't I just use a VoltMeter Display (all over Ebay) on the battery supply, and know that I'm fully charged around 42v, and off the bike before 30v??? I found a waterproof one with a touch power button: www.ebay.com/itm/DC-5V-48V-Waterproof-Touch-LED-Panel-Digital-Volt-Meter-Display-Car-Motorbike/123935695413?ssPageName=STRK%3AMEBIDX%3AIT&var=424719743811&_trksid=p2057872.m2749.l2649 I know it won't give me distance, but after getting to know how my voltage drains over several rides, I should be able to estimate things and apply a margin of safety, right? Also, since this isn't a flow through system I don't need the heavy wiring, and can just lengthen the wires to mount this on the handlebars....

[@DanielLopes-jt8yl]

Cool!

[@funwithry1320]

👍🏻👍🏻👍🏻

[@christhilton3600]

👍 thks...

[@heardandtested]

I use the $9 one

[@hatschmolo2923]

You are mistaking "capacity" for "power" all the time. This Video will not help anyone except for people who sell overpriced powermeters. The best way to tell how much capacity is left is to measure the voltage of your batterypack. Powermeters can only show volts x amps (with shunt) = watts

[@rss3709]

shower stall for recording has bad sound

[@EbikeSchool]

Fine, you win. I'll move it to the bathtub for the next video...
