For years, Micah has helped to make it more possible financially and technically for folks to acquire for themselves, small vehicle electric transportation. And he endeavors to bring more useful information and products needed in the future as well. The competition does not like that. He is really a nice fellow that loves people and wants to help others, and he does spend the time and effort to do so. A+

[@russbilzing5348]

Thanx for the advice on balancing the battery as well as uneven voltage loads. These are important little nuggets.

[@mikebravo6636]

Thank you Micah, just what i asked previously to double distance on my Orbea Gain. Bought your solar panels book. Very informative.

[@barryallisonve3njk]

And yet another very informative video. Thanks! PS DIY battery book is a must for anyone wanting to build a battery pack. I've read my copy more than once and learn more each time. Thanks Micah.

[@johndavidpeer3107]

Subbed. What a great video! I loved it; From his reasonable pitch for his book, to what he creates in the end, that blew my mind! There's a business opportunity with someone with the basic chops! Including sewing even. Awesome.

[@theairstig9164]

I used a step up voltage converter and two Ryobi One+ 18V batteries in parallel. As the batteries are removable I can charge them both at the same time as the scooter if I have three sockets. The step up converter provides a constant 52.2 volts in to a 54 volt pack at about 3-4 amps. This means the 18 volt batteries are delivering in excess of 10 amps until they are completely drained. The power protection electronics in the batteries shut them down if they overheat or under volt. It’s a few layers of protection but if the batteries die, I just buy a another One+ battery. Do not connect the supplies with more than 1 volt difference unless you like loud bangs. I already have a copy of your book

[@nrgcominc]

I like your videos a lot. Keep up the great work. I have the same scooter. Behind the black panel is the controller board. What I did was cut the battery battery wires that lead into the controller and put xt-60 female, then xt-60 male into the controller. I pulled them outside of the black panel. This way to use the built in battery just keep them plugged in. To use the spare battery, I just unplug the built in and plug the spare in. I keep that one in my backpack and it is double the capacity of the original. The difference is this does not send the spare battery's output to charge the built in battery. That is why the range wasn't double. In my case with a 2x spare I have triple the original range. Thanks for your videos. I enjoy them.

[@micahmartin4601]

Awesome Micah. The sewed bag is a nice touch.

[@Cho.0k]

Thanks for the time and effort you put into these videos! A video on wire gauges for power wires and battery capacity would be great! I want to build a pack, but worry about burning up the wiring if it supplies too much power :p

[@neumy1944]

Thanks for the instruction. I can't seem to afford anything for myself so I have to build it all. Electric and electric assist is next on the DIY to do list. Can't wait to put it into practice.

[@LifeHacksTipsAndTricks]

I just got the HiBoy S2 scooter and it is great. I love how simple this process is. I have some recovered laptop batteries that I would love to repurpose for this.

[@JapRapNipHop420]

hey I just bought the HiBoy S2 also. So you followed his instructions and you get twice the range now?

[@LifeHacksTipsAndTricks]

@@JapRapNipHop420 I haven't actually done the project, I was interested, however, with young children I don't have the time.

[@rogerlane2282]

Does not work on the hiboy S2. Don't waste your time. I did a video on how I did it. I can not travel about 23-26 miles distance with two batteries :)

Your videos have helped me make my own electric scooter. Thank you for making them.

[@OH8STN]

Awesome video. I've been wondering whether or not to build/buy a second battery for the eFat bike. Perhaps a booster pack is the way to go. As always, thanks for sharing 👍👍👍

[@MotoScoutOut]

I started watching because of the electric motorcycle videos, but you are drawing me into the e world. Great project. Would love your book and more videos on the bike you bought.

[@metalman69201]

Warning!! These Electric bikes and motorcycles are addictive! I started two years ago and have built several electric vehicles including a solar electric recumbent trike that hauls me and my two teenagers around, and we have done trips of over 100 miles with it and have gotten great results running only on Sunshine! [e-mail] if you'd like a picture of the solar electric trike.

[@awo1fman]

As always, an excellent instructional video. Looking forward to your next project.

[@kyfish-on3203]

Very nice demonstration of building your own battery! I'm making my own 48v lead acid setup and just completed the battery box today. I will be following this same method for the purpose of the Maiden Ride, It will be helpful to have this backup power when needed, switched, or just as you have demonstrated! Send me your book Maaa'n! I promise Im gonna need it!

This is definitely rocket science I need that book ASAP !

[@victormartinez7331]

Awesome video. Thanks for the great info; i am motivated to add another battery to my scooter to increase range; was a little afraid, but i now understand what's needed. Thanks

Like the sewing - pretty and well protected! 3d printing is also an option. Not too hard to find printers today that can easily print 30 cm langth, and in strong Abs or petg which can also be water resistant if you feel adventurous

[@vexix6321]

You make some really good videos dude, keep up the great work!

[@Tennouseijin]

I suppose it would make sense to put a fuse in there too, just in case you ever accidentally connect the booster when the two batteries are not at the same voltage. Anyway, I'm looking for good sources of info on building a 'split pack' where a vehicle does not have a convenient place for a single large battery, so you might want to put multiple smaller batteries. While the basics are obvious (the batteries can be connected in parallel or in series, as if they were a single cell), and some safety concerns are obvious (keeping the same series number when connecting them in parallel, making sure everything can handle the voltage and the amps etc.) but some details are less clear and it seems there are different ways to do it, different ways to solve the problems inherent to this system, and I haven't yet found a good definite place to look for information on that.

[@RPRosen-ki2fk]

Thanks, and I liked that you showed a non welding way, to build the pack.

[@timeizrelative2]

welding is a lot safer tho, i would suggest soldiering the connectors after to prevent loosing from vibration during riding! Or just by an inexpensive battery pack on ebay.

[@beatnik1855]

Glad u gave the "before u plug in the spare battery warning" I was waiting for it

[@richardaffonso1233]

I always love these battery videos.

[@brokenwishbone422]

Thank you for this video! I have experience with residential electrical work. Someone in a BMW hit my car and ran from the scene totaling my car. Insurance paid for the accident but it was not enough to get a reliable car without picking up a new car payment that I can't afford. I already eat rice and oatmeal everyday as it is. I commute about 8 miles per day. I bought a new E scooter in December after the insurance payout. Best $500 dollars I have ever spent, literally!! I bought the Hover 1 "Alpha", but everyone seems to have the step down version called the "journey". I get to and from the doctor, a total of about 8 miles in eco mode 6 days a week. Even when it has been 19 degrees fahrenheit, here in Maryland, in the mornings. I definitely thought about adding a battery pack to extend range. I didn't want to open the machine and void the warranty I paid for. Now that I've seen you do the same thing I have been contemplating I think Im am going to give it greenlight and order the batteries and bms this weekend, Thanks again , Joshua ps sorry, I dont usually type much but a proper thank you was due here!

[@m.s.5914]

Its perplexing how much people use things but don't have any idea how it works or how to fix it. Down to the simplest can openers (or even the can itself).

hey great video , WILL THIS WORK ON MY KAABO WOLF KING GT 72V the ato switching one. and will it drain from both batteries at the same time so I get less voltage sag also would a simple parallel conection work if I use two 72v batteries one is 35 mah and the other is 32. Will it work with no issues

Thanks alot for the video bro, was really helpful for us us noobs to understand. So as long has my new battery pack is the same 72 volts,I can still use a higher A.H ( 80ah) than the existing battery (35ah)?

[@sanman187-]

Just what I was looking for, Micah! Thank you!.

[@cedrikkaurit3078]

How does the charge port handle a battery connected directly to it? If I look at the wires behind the charge port, they are way thinner than the cables connecting directly to the original battery. Will the extra battery load work with the charge port or is there risk of faster wear in the long term? Maybe swapping out the charge port wires to thicker gauge wire would be a good idea?

[@nosdehgan4401]

Great video. I have a electric wheelchair attachment called firefly and it has a 250 watts hub brushless motor and runs on a 36 volt 6.6ah battery.

Hello, I would like to improve the battery of my Electric Scooter Xiaomi Mijia M365 but I am not sure if I extend the battery that has been adding more batteries and using the same BMS and also expanding its room with pieces of 3D plastic or adding an external battery. There is also the possibility of extending the battery by expanding its voltage to increase the speed of the scooter and for this it would need to modify the BMS with 6 mosfets and condenser 100v 1000uf. I need the scooter to move around London UK at a distance of 30 to 40 miles round trip and charge at home. Thanks for the video it helps a lot to understand the world of batteries and electricity.

[@psy881212]

just bought your book, amazing job and videos, i assume the charge time for your battery took 2x as long as before with the same charger you used for charging the scooter prior to the battery upgrade? also the battery indicator on the scooter, i assume it reflecs the percentage of the remaining power left for the old battery which should approximately equate to the same percentage of remaining battery in the new scooter as both the new and old batteries should have the same voltage? Are these both answers yes?

[@flaviomiranda4918]

Question, what are the part numbers for the plugs you used? I cannot find them in the list of things. My son has a GoTrax G2 and I want to build him an external battery for added use time.
