batteries

I've not been here much since I didn't buy any new bikes during the main COVID period. Just been working on my own. I've had some great trips, but less this year as I've had to dedicate time to other things. Both my bikes need new brake pads, and the RCS mileage reset again at 2500km. So...

I'm in the process of building up an e-tandem. And when I say building it up, I mean I've selected all the stuff I want on it and am having a builder in Denver, CO (da Vinci Designs) build it. Due to supply chain issues I am still looking for the battery, a Shimano BT-e8016 630Wh. If anyone...

My wife and I have been riding a tandem bike for almost a decade. We've recently retired and are now building up an e-tandem. When I say building it up I mean we've selected all the stuff we want on it and are having our builder in Denver, CO (da Vinci Designs) build it. It was ordered in July...

Hello community! I am about to purchase an Aventon Level after months of research on the best bike for the price. I have a perhaps silly question, but could I swap the 500W stock for a higher grade, say 1000W or even higher? That being said, will the bike frame, motor etc be able to handle...

I have only had my M2S All Terrain Sport R750 Integrated for a month now. Yesterday, the battery vibrated out of the cartage, and I was just riding it in the road. Yes there were bumps and rough road, BUT that is totally unacceptable. Just imaging riding this MTB on a trail. I didn't just...

I've been searching for a chart that converts battery voltage into a percentage, and have found some for 48v. But it doesn't show what Ah the chart is for. So I'm wondering if there's any difference in voltage between two 48v batteries that have different Ah? I have a Yonglin 80c display where...

I've been researching several ebike manufacturers (e.g. Amigo, NCM) who use batteries assembled by DLG in China. I've read the best battery cells are produced by Samsung, LG, and Panasonic. I've also heard DLG uses cells from Samsung and Panasonic; however, I'm not certain I can trust that...

Hey, I have an Emmo knight and I am able to get about 16-18km on a full charge on speed mode 2 without going too hard. I opened up all the fairings and tested all the batteries and they all have over 13V, I’m about to pull the trigger and buy new batteries but I’m still not sure how to test my...

Yesterday I started researching into the batteries for our NCM bikes. NCM has them listed as DeHawk which is using the Chinese made Reention Dorado+ Series battery cases. Here's some data I've collected recently while searching for a 48V 21Ah 505mm compatible battery for my Moscow Plus. I will...

With my old ebike, the 36V/12Ah battery needed a recharge cycle after every commute, that isn't the situation with the CCX's 52V/19.2Ah battery. While I liked the idea of removing the smaller-lighter battery and recharging in an indoor environment, a 13pound monster battery pack seems happy with...

One thing I hate about winter and e-biking is the cold. I commute every day back and forth to work for a total of about 12 miles a day. Although it does not snow in South Louisiana often but it does get down into the teens and 20's fairly often throughout the winter. Another thing about...

This thread is dedicated for helping new E-bike owners to understand and maintain their batteries in the best possible way. There is a lot of confusion for any new E-bike owner as to how one should treat their batteries: Shop owners may say one thing, online resources may another thing, someone...

I bought a couple Vruzend kits and attempted to make my own battery. Not sure if the BMS is faulty or if I just have no idea what I'm doing (probably the latter) but somehow I killed 7 of the batteries. I tested the others (21) and they are all around 3.4v so the rest seem fine. If you want...

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 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...

Hey everyone, I was wondering if you could suggest some guidance for wiring two batteries onto one Sondors fat bike? I have a running bike, and I can mount a small spare battery anywhere. However I am weak on wiring, and I don't want to set the bike on fire. Anyone done this before...

This is my problem........ Everything was working great......parked the bike outside for a couple of weeks, brought it in to charge. However, after having been charged, I took it out for a spin and almost immediately the motor cut power.......only to be restored several seconds later.....which...

Here is some background on my effort at resolving my battery issues, after reading suggestions on EBR forums and advertisements from RPE, I made contact with RPE. First with an email communication back in September. Back then, RPE made a reply to my initial inquiry with a response which...

The 36v 12Ah battery for my EG Zurich is losing reserve capacity and maybe should be replaced. I have nearly 300 recharge cycles and 5100 miles tallied. The battery seems to be running out of power more quickly than when it was new. Making a call to (Link Removed - No Longer Exists) and...
