    Ebike + Multi-function Computer

    I don't know for sure if its electrical interference but the spokes on the front wheel are already magnetized which leads me to think that it is affecting the sensor. The rear wheel (the one without the motor) is not magnetized. I have tried repositioning the magnet to a higher part of the...

    Ebike + Multi-function Computer

    I have a mountain bike with a BL-36 kit on it and just recently installed a cheap Bell 15-function bicycle computer only to realize that it doesn't seem to work with an electric bike due to the electrical interference generated by the motor. The bike computer is the basic type in which you...

    Bike shuts off when riding. Whats going on?

    Update: The last couple of days I've been able to ride the bike for 10-15 miles without a problem. I usually let the batteries charge for a good 18+ hours before riding again. Everything seemed fine up until today when I took it for an extended ride somewhere around 18+ miles and minimum...

    Bike shuts off when riding. Whats going on?

    I let the LiFePO batteries charge for well over 24 hours, re-connected them to the controller and was able to ride the bike around the block for the first time in quite a while. I really didn't do anything differently except let the batteries charge for a while. Weird. I'm going to...

    Bike shuts off when riding. Whats going on?

    I reconnected my old SLA batteries to the bike and they appear to be running fine. Next, I will test the voltage on the cells in the LiFePO batteries. I'm hoping the problem is just with the BMS. If so, where is the most reliable place to purchase one?

    Hello cammycc, Yes, the battery was fully charged before I used it for the first time.

    Bike shuts off when riding. Whats going on?

    I believe it was another vendor since "CammyCC" doesn't ring a bell. Yes, I have the one on the left in the picture you sent. 16.5 pounds sounds about right for the weight of the batteries I have.

    Bike shuts off when riding. Whats going on?

    Thanks. I'll try reconnecting the sla's and see what happens. However, the sla's have been just sitting there in my garage for quite a while so I'm not even sure if they are good anymore.

    Yes, its an ebay China special, lol! And the BMS is exactly like the one in the picture you sent. Hmm....

    Bike shuts off when riding. Whats going on?

    I don't know how to do that. I'll search the forums here to find out though. Unless its quick and you could explain? The BMS did get dropped once but I didn't think it was that hard of a fall.

    Bike shuts off when riding. Whats going on?

    I have a Wilderness Energy BL-36 eBike that I have replaced the SLA batteries with LiFePO4 cells. The motor is 36v 600w The LiFePO4 battery is 36v / 20ah Whenever I lift the front wheel (with the motor) off the ground and turn the throttle, the motor kicks in and runs fine when there is no...

    Help w/ converting to LiFePO4 from SLA

    Its ALIVE!!! Its ALIVE!!! The problem was the connector that came with the kit. I don't know why but power simply was not getting through. I cut the connector out of the equation and wired the battery bms directly to the controller using standard disconnects (to easily disconnect the battery...

    Help w/ converting to LiFePO4 from SLA

    I just bought a voltmeter and tested the leads on the battery. The meter shows between 41.9 and 42 volts. I tested the original SLA batteries and they came up 39 volts. So I'm pretty sure this means the battery isn't dead, right? It seems that no power is getting through the adapter that...

    Help w/ converting to LiFePO4 from SLA

    Ok I'll go and get a meter. Its something I know I've been needing to get anyways. Unfortunately I have to go out of state this weekend and won't be able to get back to this until after the weekend. I'll get my meter and test the voltage on the batteries soon and post the results here...

    Help w/ converting to LiFePO4 from SLA

    There are two wires for the charger which have been soldered onto an adaptor that connects directly to the charger. These are seperate from the other two wires that are red and black, which I assume are the power connections.

    Help w/ converting to LiFePO4 from SLA

    I should also point out that when I received the battery from China, the Material Safety Data Sheet that came with the battery says that this is a LiCoO2 battery and not a LiFePO4 battery. I immediately contacted the seller and they insist that they made a mistake and that they only build...

    Help w/ converting to LiFePO4 from SLA

    Ok I just went and stripped some more wire and twisted both leads really well so I'm fairly confident that they are making a solid connection. When I tested it, still no power. I reconnected the SLA batteries as they were before and, yes, the bike still powers up as normal. The controller...

    Help w/ converting to LiFePO4 from SLA

    Thanks for the quick response! Yes, the battery came with a BMS circuit board. So the battery is connected to the bms, and then the positive and negative wires coming from the bms have been spliced onto the original wires that were originally connected to the SLA batteries and conncected to...

    Help w/ converting to LiFePO4 from SLA

    HI, I'm new here. Definitely glad to have found this community! I know I have tons of info to read through now. Here's the deal, I have an e-bike built using the Wilderness Energy BD-36 kit. The e-bike is a 36v 600watt front hub motor with a 50amp controller. I don't like the SLA batteries...
