I have an e-bike that was manufactured by a start-up that folded. I cannot get replacement batteries and mine are deteriorating. I would like to find a company that rebuilds lithium batteries or find someone with experience substituting other batteries. If anyone has a lead, please share it. I tried Batteries Plus but they don't rebuild lithium batteries. The battery kits I've seen online look easy, but the wiring is a question. I would like to find someone who can connect the wiring properly. Thanks for anything you can tell me. The bike is a Freway VR-01 with a 36v lithium battery.
 
Hi, I looked up your bike and you have a sit on frame external battery, so you have a lot of options. I looked at the stats and it says it's an 8fun 36v Bafang hub motor, so you have even more options. Basically, a lot of the Bafang kit batteries should fit it. The company FTH Power in Walnut CA. Should be able to help you. You could always change the frame bracket and fit other Bafang type batteries to it. If you open up the battery bracket on your bike you will be able to see which stock
connector is in there, for Bafang, they are all fairly available and it could be moved over to a different bracket. If you have trouble with any of this, you could always go to Johnny Nerdout's web site. He builds ebikes for people by mail and works extensively with Bafang components. You really just have to make sure a new battery will fit in your frame, if you go with a new one and don't have the old one rebuilt. I will post a pic of the connector I think you are going to find.

If you're in the states, checkout Northeast Battery Systems out of Windsor Locks, CT. They may be able to completely replace the cells in your existing batt. They are very responsive and helpful. I sent them one of mine just this morning.

 
I just wanted to give you a heads up. Your current battery bracket may have your controller box in it, one site I checked said no, one said yes. They don't design them this way much anymore but yours is an older design.

If it does and you need a new bracket you can easily enough move the controller to the frame, especially if you want a battery with more amp hrs. Other than that, You can do as the major suggested and send it to one of the two places above for new cells. Let us know if you run into trouble.
 
Thanks. I reached out to FTH Power and they have limited their use of Bafang. They let me know that later this year they hope to be able to rebuild batteries. I am waiting for Northeast Battery Systems to respond. I'll post whatever I learn from them.

I have limited space and limited know how when it comes to DIY. However, I will certainly give it a try if all else fails. I appreciate the information.
 
Thanks so much!! Really appreciated! Our product is already sold B2B to bike manufacturers, and we will open our Kickstarter in september for B2C customers! (We need a Kickstarter although our product already exists, simply because we are still a startup and we cannot pay the production costs upfront for B2C customers, so the Kickstarter format let us get the funds first to buy the material, then produce the batteries). Production is quite fast, we should be able to ship in October/November!

If you're interested, I highly recommend you to pre-register at https://get.gouach.com: if you pledge $1 now, you will get 33%-off on the Kickstarter (so pay only $330 for the whole battery and fireproof casing, instead of a retail price of $450)

Let me know if you need more infos!

A lot of our technical doc is available at https://docs.gouach.com if you're a geek/engineer like we are at Gouach haha
 
And please talk about this to anyone you think could be interested, we really want to put our sustainable and repairable batteries in the hands of as many people as possible, we believe that people should be in control of the stuff they own!

Thanks. My only question is installation. How will I use this battery on my existing e-bike? And is it compatible? My bike has a 36v battery and a 250w bafang rear hub motor. I don't know if I can properly connect the wiring. If I had some idea it would work, I would wait until October to purchase.
 
I use one 18650 mh1 cells 3200mah 10amp continuous. $5 nickel $15 bms takes about an hour to build a battery. The wiring is really easy after you do it once. If your close to SF I'll rebuild it for you for nothing. I have a 52v 19 ah with the cells I mentioned and it never goes dead. I bought 30 36v batteries for $100 from super pedestrian scooter rental when they folded. Do you have a good pic of the battery? Measurements? The frog is a good battery solution. I put them on BMX. Hangs on the seatpost.

I have attached several pictures of the wiring and battery. I sent the battery to a fellow who rebuilds batteries but he couldn't figure out the wiring from the pictures and did not want to rewire unless he could test. He sent the battery back. Additionally, the on/off switch has failed and needs to be replaced. I use velcro to turn it on and off. I live in Santa Fe.

Ok off the top of my head this is what I see pic one is called a julet connector. That one contains power for three phase hub motor, three hall sensor, and +/- also for hall sensor. 3 Power wires are a little bigger. Hub motors are brushless motors that are three phase meaning three seperate wires for 48v. The smaller wires are one for each power wire and +/- to power hall sensor. That monitors have angle. It gets technical but in short it makes the stator spin smooth rather than jerky.
PIc 5 is the back side of where your battery case plugs in. Red is power into your controller. Black negative. The other two are either both sides of a switch or positive and negative coming from the charging port. I would have to follow the wires and see.
PIc 6 is a brushless motor speed controller made for an electric bicycle. That should have one cable coming out of it that goes up toward the handlebars that has eight or nine wires in it. That is five wires for the display and three wires for the throttle and either two or three wires shared for both brakes. The positive and negative is shared between all three that's why the number of wires doesn't add to eight or nine. A black and a red to the battery. 14 pedal assist. One that has the three phase wires and the hall sensor. And if there's anything else coming out it's either lights or mine has a speedometer that comes out. Most of the time trouble shooting an e bike is easy. You should get a cheap multi meter if you don't have one. $5 on AliExpress. Your battery holder has your motor controller incorporated.
