Thank you!!!!!!! I was able to save a "broken" unit. These companies are insane charging what they charge and even absolutely refusing service if you are not the registered user.

Good Afternoon Jeff - I appreciate your efforts to help those who need an affordable battery for their SmartDrive. The SmartDrive is a well thought out, excellent product. Their replacement battery at $1600+ for a battery that can be manufactured and sold for $59-$70 is a bit steep for anyone let alone someone who requires a wheelchair for mobility. Following up on your kind KZread providing an explanation and demonstrating how an affordable hoverboard battery can replace the $1,600+ replacement battery designed for the Smart Drive, I have designed and made a nice fitting box to contain the battery you've shown here with standard attachments to the smart drive, fitting attachments for the computer board, and attachments for the buzzer. If you provide a contact address, I will send you photos of same and if your request it, follow up with one of the boxes. Looking at some of your you tubes, you are a fine example of "running" with the gift of life. Thanks for that. Mike C.

I'm not sure if you are an Instagram user. I don't use it much but do you the messenger feature. You can send me a message @duneroller and I'll reply as soon as I get the request. I don't know a safer way to get in touch without posting email on a public post. I'm very interested in the box and how you are making (printing?) them.

Excellent, just watched your other video, this one will be perfect for my used mx2+

I was able to rebuild my pack for $ 180 Canadian getting them from 18650 Battery store , but you need access to spot welder for the nickel strips you also need . Did you mention scooter battery .

If you found my channel, mine is better solution. As good as original pack, runs for 4 km and still show 3 led.

18650 may have 3.7v The original is 3.2/3.3v

I would like to make a wire conversion harness to connect the main power connection on the stock battery to connect to the connector on the hover board battery which is a SL60. Can you (or anyone) tell me what the identifying number is for the stock larger battery connector - and where I might purchase one? Thank You for your help on this.

I don't happen to have one apart right now. Most of the other connectors are Molex Wire to Board connectors. They are also known as "plug and socket" connectors. For example, the RS232 plug from the battery is a CLIK-Mate Molex. The wire to board Molex connectors can be found here. www.molex.com/en-us/products/connectors/wire-to-board-connectors. The connectors can be complex. The plug and socket connectors are sold separately from the male and female plug housing. I have many sets of connectors and crimping tools including several Molex and JST (Japanese Solderless Terminal). The connectors don't match any of the common plugs I use on RC, motorcycle, and automotive applications. I'll take a closer look next time I have it apart. If you are dead set on not cutting the wires start by measuring the pin-to-pin distance. This is the pitch of the connector. Identify if the plug connectors are round or blade next. Then locate the corresponding family and part number. Digikey stocks many individual parts and crimpers. Let us know if you find the exact connector.

Can i get the information on the hoverboard battery?

I used a 36 volt 4.4AH (4400mAh) 20 cell (10S-2P) with outside dimensions of 135X70X60 millimeters. Some descriptions will say 135X75X60 which will still fit. There are many options on Amazon or eBay.

I use he newer "rotary power" controller to turn on and off and vary the speed of my SmartDrive. It plugs into the same socket used to charge the battery. My question is - if I splice the two power wires in the hover board battery into the original power wires (red and black) and use the same connections into the circuit board - do you foresee any damage or issues from that layout. Since the hoverboard battery has its own integral BMXXXX board - am I OK ignoring the two sets of plug ins from the BMXXX board that exists in the original $1,600 SmartDrive battery, or do I need to integrate them somehow into the new system's circuit? I'm unsure of how the 2 plugs from the BMXXX origional battery interact with the circuit board??? Can it be ignored since it appears that the new hoverboard battery has its own integrated BMXXX? It appears to me that the new hover board battery can be plugged into the existing circuit board and be charged from the origional charging system/plug, and enjoy a long, happy life doing its work. Thank you MUCH for the time you've taken to design and KZread post a solution providing an alternative using a more reasonable $50 to $100 battery to being forced to purchase a battery proving lesser service for 15 to 30 times the cost. SmartDrive is a finely designed product. Their product and battery costs however significantly gouge those who are unfortunate to be mobility handicapped as well as the insurance companies or uninsured people that are seeking a way to be mobile without wearing out their shoulders in the process. I look forward to your response and/or any knowledgeable answer posted.

The accessory wires and plug are separate from the charge circuit. I don't see any issue with the splice and connect as shown in this video. The original battery should have 3 connectors. One to the charge port, one that supplies power to the circuit board (heavy wires) and the rectangular RS232 from the BMS to the main controller. The hoverboard battery does not have a separate charge and power from the BMS so the charge and power plugs need to be connected in parallel as shown.

Good Morning Jeff, Wow! thank You for a fast and helpful response to my question. I will complete the new battery installation today. Thank You again for your consideration in finding and YouTubing a solution for wheel Chair users who cannot pay $1,600 for a battery that with a simple modification can be replaced for $50 to $100. Best Regards - Mike C.

Good Morning Jeff, I'm a bit of a dinosaur but I'll ask one of my daughters how to use Instagram. If I can rub two rocks together and figure it out, I'll send you photos of the battery box, and if you wish - one of the boxes. I used to own a plastics injection molding business down here in San Diego and for over 20 years designed and built production injection mold tooling and finished products for my customers. I moved some of my CNC equipment to my home "shop" when I retired and also still have several - 3D printers which is what I made the battery boxes with. The fit is perfect and I have to say that its a really good looking system. The only thing that keeps it from being a complete "Plug and Play" for the average person is that two of the wiring plugs require a short extension which could be easily made by someone with basic electronics skills. The box is simple to manufacture. A 3D print with a Bambu printer takes just under 3 hours in PETG. An injection molded part would take about 20 seconds. My concern about possibly manufacturing and selling them inexpensively is potential liability and the yet unexamined cost of liability insurance. I've considered sending the design to Smart Drive, but I suspect that they'd rather continue selling their batteries for $1600+ instead of a longer lasting, lighter weight one complete for $100 to $200??? If I can figure out how to use Instagram we can trade thoughts on that later. If you have thoughts on this that won't end up with one of us dealing with un-necessary liability kindly unfold them. Best to you.

I would love to get a plug and play kit out there. I'm not hard to find if you use Facebook, Instagram, or LinkedIn. I'm in the Madera, CA area. We would need to discuss how to limit the liability while still giving the users an option. I'm currently in the environmental field and my LinkedIn picture is about 10 years old.

How is it holding up?

Nice.. I’m going to try to do this to a friends of mine’s smartdrive. He probably used it once and didn’t use it much after that and apparently the battery got messed up. Which is crazy . Thank you for the reply.

My daughter asked me to send photos to her with your Instagram address and said she would send the photos, my e-mail address and phone number to you to make more private future communication simpler. She is with a client/patient now and says she will get it sent by some time this evening. It will be nice to talk with you. Best Mike C.
