This recall involves 36-volt and 48-volt lithium ion rechargeable batteries sold separately and as original equipment with Pedego electric bikes. Recalled batteries of each voltage came in two styles. One style has a silver or black metal case that measures about 13 ? inches long, 6 ? inches wide and 2 ? inches high, with black plastic end caps and a handle. The other style has a black or white plastic case that measures about 14 inches long, 6 ? inches wide and 2 ? inches high with a red indicator lamp on one end. The batteries have serial numbers that start with “DLG.” A label with the serial number is on one side of the metal batteries and on the underside of the plastic batteries.

Hi Court. I am a bit of a newbie but learning fast. Thanks for your help and the reviews. I like the idea of geared hubs and torque and 500 W w/ 48 amp. But can I be more experience specific? I’m about 180 lbs and moving to San Fran. I love the flats of the marina, the Embarcadero, Chrissy Fields, the Presidio etc but I live on the hills of Pacific Heights, some quite daunting. I also love to just cruise along and look. i like step thrus. I like to sit up in comfort and I love comfortable seats. Can you taylor make a reccomendation for me as to bikes to look at? The Pedego City Commuter looked interesting but the seat wasn’t comfy. I want ease, assist and throttle, cruiser comfort as well as nibble and quick with good endurance. AND critical, I want ease on the steep hills of Pacific Heights. Thoughts? Help?
Technically yes, you can bypass the BMS for discharging and just charge through the BMS but this is not recommended. It is better to just choose a BMS that can handle your 50A discharge. BesTechPower makes some great BMS units that can handle 50A and more, depending on the model. They have many options.
Cheers Court! Maybe you have some insight into a great question a friend asked me: “If there were a scientific experiment done where all variables were the same with the exception of the drive motor, one being a mid drive and the other being hub drive (both of good quality and used on higher end mainstream e-bikes), is there a clear winner when it comes to which drive system delivers more efficient power. I guess what I’m hoping to find out with this question is: Which style of drive system more efficiently transfers the potential energy in the battery into actual motion. I could see this being answered with units like distance or speed, but remember the only thing I am comparing is two types of drive systems… Things like battery size, pedaling effort, rolling resistance, total bike/rider weight, air friction are all constants. So is there a clear winner???”
Next, we’ll need to wire multiple 18650 cells in parallel to reach our desired pack capacity. Each of the cells I’m using are rated at 2,900 mAh. I plan to put 3 cells in parallel, for a combined capacity of 2.9Ah x 3 cells = 8.7 Ah. The industry abbreviation for parallel cells is ‘p’, meaning that my final pack configuration is considered a “10S3P pack” with a final specification of 36V 8.7AH.
E-bikes can http://huntneqip.com provide a source of exercise for individuals who have trouble exercising for an extended time (due to injury or excessive weight, for example) as the bike can allow the rider to take short breaks from pedaling and also provide confidence to the rider that they’ll be able to complete the selected path without becoming too fatigued.

Be warned: some less-than-honest vendors try to pass off nickel plated steel for the pure stuff. They often get away with it because it’s nearly impossible to distinguish between to the two with the naked eye. I wrote a whole article on some methods I developed for testing nickel strip to make sure you get what you paid for. Check it out here.
I’m mostly familiar with BesTech’s 72V BMS’s and haven’t used a 52V BMS from them, so I can’t give you a recommendation on a specific 52V (14s) BMS from them, sorry. I have used this 14s BMS twice and it’s worked great for me on two 14s7p packs I made with Samsung 26F cells.
What could I build to go up a mountain path? say 4000 ft long. It’s too steep for me & most bikers to pedal. I want to assist ..but the motor drive train will do most of the work. Down hill one needs good brakes or something electric generating. I bike 5 miles now up and down local hills but walk up the steep hills for sure. For a good bike rig …I would enjoy building a few prototypes. Any advice appreciated…I love to bike on green trails!

Amazing article, just what I needed. Have been doing LOTS of research but have struggled to find any real answers on which charger I should buy for my homemade battery. I am making a 48V 13s4p battery with a BMS (with balancing) like yours but am stuck as to whether I need to buy a normal bulk charger or a ‘smart charger’ that will balance the battery. My question is will the BMS balance the battery on its own or will I need to get a charger that balances also?
Hi Court, I discovered your site and it’s great. I’m 6’8″ tall, 274 lbs., and 71 years old and still biking but needing some help and assistance on long hills of pavement or crushed rock. Wouldn’t mind having a few coasting breaks too. And the step through appeal to me as I get older. Looking at ebikes and especially the Pedego step through Interceptor with magnesium wheels for weight carrying capacity. What do you think? Good choice or is there another out there that would fit this old boy?
I just found your article, and as if it were destiny, this is exactly what I am trying to do (build a battery pack with BMS, and charge with charger). I am new to this, however, and have a question or two…
Hi I was looking into getting a electric bike my job is 20 miles away I found this bike online do you know anything about this company I watch a lot of your videos on YouTube but I don’t know what I want to buy just yet to many to choose from and I just want to find the best one for me here is the name of the bike falcon ghost 1500w Thanks for all your help and resources
I am in my early 60s, weight 165#, and in fairly good shape but atlas do not have the stamina and leg strength I used to have even in my 50s. Aging sucks! I live in a hilly rural area and do most of my biking on paved and unpaved (70/30%) back roads for recreation and exercise. The latter includes gravel and hard packed dirt and the occasional deeply rutted farm road. I do not intend to do any serious mountain biking nor commute using this bike. The routes I take have several long and moderately steep grades which is good exercise but too exhausting to tackle these days on my non-powered carbon road bike. My priorities are the optimum combination of comfort (including relaxed geometry), quality/reliability, versatility, range, and ease of use.

Here is a picture of what the inside of one gearless, direct drive hub motor looks like. You can see the magnets glued around the outside of the cylinder and just inside from them are electromagnets (made from metal and copper wiring) that create repelling force to drive the motor forward without the use of gears:
Given the new trend to make electric bikes look just like other bikes, I am guessing that some creative manufacturers will come up with some radically cool ideas. I wouldn’t rush into buying one of these battery types, however, until they prove themselves in terms of battery life.
Convenience, simplicity, mobility and comfort are all embodied in our 20” and 26” folding eBikes. The perfect travelling companion for RVs and large boats, our folding eBikes pack a lot of power in a small foldable package. Also great for apartment living and anywhere space is at a premium, our bikes are the perfect example of getting big power out of a little package.
Hi Court, I am considering buying an ebike for touring. I live in Australia but would like to take it to Europe to tour so it has to be as light as possible, capable of carrying some weight (25 kg) plus me at 65 kg. I like pedalling but just need a little extra boost to go around 50 to 80 km per day. Stability is important, speed not so important. Any thoughts?
In response to customer questions about the display, we posted a video detailing the basic setup of the LCD during installation of the kit. You will need to adjust the settings for the motor type, wheel size, and battery voltage in order to match your specific kit. Detailed instructions are available in the E-BikeKit manual, E-TrikeKit manual and LCD Quickstart Guide

I figured this would be a critical step I wouldn’t want to mess up. Thanks for the advice on using the multimeter. That’s good to know as I thought I might need to open up the controller and see which wires went where on that male xlr connection which I guess would be an option too. Thanks again!
