    NCM Battery won't turn on unless "jump started"

    Hello, I have a NCM Prague with about 400km on it. When the bike has not been used for a period of time the control panel on the bike will not turn on the battery/bike. The battery capacity button also doesn't turn on the battery/bike or show the battery capacity. I've never timed...

    Battery compatibility question

    Hey everyone, I'm a pretty decent home mechanic, but very new to the e-bike world. I bought a conversion kit off eBay recently without really doing my homework beforehand. The battery pack it came with doesn't inspire any confidence now that I've read more about them, so I'd like to return it...

    Speed for low price

    I want to get an ebike (or a moped or motorcycle) that can go up to at least 55kph and is under 3000$ CAD (or a little bit more if it’s really necessary). I am willing to build/modify it if need be but I don’t want something that looks like a DIY project done by a 12yo. I already got a Sondors...

    How the heck do I legally ship a spare ebike battery domestically???

    How the heck do I ship a spare e-bike battery??? Just the battery, no bike. It is a 480Wh Lithium Ion battery for a Specialized Turbo Vado. Unfortunately, the local FedEx and UPS stores said they are unable to pack it up for me. It is being shipped domestically. So it can go via ground...

    Fixed CCS lost key by cutting retention mechanism & replacing?

    I lost a key for a Juiced CrossCurrent S standard battery and I need to replace the battery. Normally, the bike is stored in my garage so I don't remove the battery & have misplaced the keys. Based on the other CCS I have (which has a larger battery), it looks like I could cut the plastic...

    Battery backpacks as a product

    Wondering if a standalone e-Bike battery backpack is a thing yet. If it is not, I'm mulling whether to produce one or at least a kit instead of the hack jobs we are having to do now. Repacked my Kriega R-15 backpack with styrene foam, cut and hot-glued to just the right shape for the 17.5 52V...

    Rize RX, battery charging

    I have searched the Forum but don't see this issue addressed, which means its probably a non-issue. The Manual states "Remove the charger from the battery within one hour after it has been completely charged. The charger will automatically stop charging when the battery is full, however...

    A look inside a Juiced 52V 13Ah battery.

    There have been a few photos in the past of the Juiced battery as people had to open them to fix the connector, this look might go a bit farther. I bought a defective battery just for the case, but turned out the case is too small to fit my replacement pack once all nicely protected. While I...

    Electric bicycle battery repair/diy

    Hello there! I recently purchased an e-bike (Batavus Padova Easy) with semi dead BMS, semi it's because it allowed the batteries to be charged fully, and that's good because it allowed me to test them, and once I did, I noticed that the batteries are OK, they hold charge decently, not dropping...
