battery

So, I am relatively new to the whole DIY battery building thing, but I've gone through a good amount of trial and error already. My latest issue is with the hot glue holding my cells together, it just doesn't stick all that well lol. I feel like hot glueing is the most common way of building...

Could really use some helpful tips right now. I built a 52v battery and the thing is overheating so bad, to the point that the hot glue actually melted and it was too hot to touch. My first thought is that the amps are maybe too high for the controller, but I'm not sure. I used samsung 30q...

Hello, New here, I was doing some research on cheap lithium battery packs for a 48v 1000w bike I'm planning on building this winter on a very cheap college student budget. Even on aliexpress, 48V 24+AH batteries are well over $500, but 24V 12AH packs are as cheap as $65 shipped (given a very...

I just purchased a Vado 3.0 and after a couple weeks of use I've noticed the battery life is less than I expected. I'm getting around 32 - 34 miles and then needing to recharge. I mostly ride in "sport" mode, but use "eco" at times as well. I occasionally use turbo mode, but it's probably...

We just got my wife a Rad Step-Thru. On a full charged battery, she rode about three miles to the pool and locked it up. She came back about two hours later and it wouldn't turn on, so she rode home under her own power. I plugged the battery back in and it charged up within a half hour. I...

What is the experience of taking the battery off and traveling with bike on rear mounted rack. What is done to prevent rain from getting in battery compartment and doing damage to electric contacts? Thank you

Many ebike batteries are lithium ion, which get 300-500 full cycles, from 100% to 0% before they pass a (somewhat arbitrary) threshold where capacity is significantly less. But, keeping energy levels between 20 and 80% can double your battery lifespan or better. From Battery University...

Hello, I am new to this forum and hope you can assist. I just bought a new electric bike, the ejoe epik se 2018 model. The dealer told me to charge the battery every time i finish riding it optimize the battery cells. I am using it to commute to work, 16 miles round trip. After my morning...

Has anyone else seen issues like this where you ride it, park it for a few hours, then come back to find what should be a 50%-75% battery to be totally dead where it displays "no battery" on the control screen? Some details around what I've tried: 1. A brief "jumpstart" using the charger brings...

My City commuter & Her step thru Interceptor have had the Plastic Battery sleeves crack @ Various points along the Mid-seam & the Screw nodules in the casing actually breaking apart. The problem was initially noticed while riding along & Hearing a "Slapping" Noise coming from the back Of the...

Dear Emotion community, can anyone recommend how to adjust easy motion neo cross battery? It is loosened now on my ebike and I want to know if there is a way to tighten it so that the curved battery sits tight on frame. Many thanks.

I have just taken delivery of the Rad Rhino .... which is the Rad Rover tweaked to comply with European laws. My question is to do with the battery level indicator. I have ridden it a few times now and am a little confused about the amount of battery remaining, I ride in Pas 2 or Pas 3 and the...

Hey, new here, well not really. I've been a long time visitor of EBR but I'm new to the forums. Anyway I just got a bike from someone and it's not running at the moment. The battery seems to have a very small charge on it enough to make the horn sound very low. But nothing else works. It...

Hi Everyone, I will try to make a long story short. Im doing a masters in renewable energy technologies and my project is to design and build a solar powered ebike charging station. It will have its own onsite storage etc and be able to charge around 3 bikes at a time. This is a first prototype...

hello, I've been wondering whether a 1000w ebike kit would be sufficient for a 52v 13.5ah battery that I was thinking of getting. I don't really need long range, approx 25km (15 miles). Mostly with throttle. Thank you

Does anyone know if this battery charger (or other ones) are compatible with the CCS stock battery (12.8 volt)? https://lunacycle.com/batteries/chargers/standard-3amp-48v-dolphin-bottle-battery-charger/ looking for a second charger to keep at work. Thanks in advanced. Andy

Hello So I'm going to duck down a bit, I'm actually doing a car conversion BUT before you move on, my question relates to e-bike batteries. I've seen e-bike battery packs for sale which are 48v 59ah with built in BMS. Could these be connected together in s2p2 format to give me 96v and 100ah...

Does anyone recycle old batteries, sell new ones for my 2015 Easy Motion Evo Jet bike? I'm doing everything I can not to go through the bike store. Larry Westminster, CO
