It’s always hard to say exactly how much AH’s someone will need because every case is different. With that powerful motor sucking lots of juice and big hills though, you are going to want a minimum of 48V20AH. http://electricbikeframes.com I were you I would try to go even higher, but it may be even better to simply have two batteries at that point. It’s annoying to swap them, but if you ever had a problem with a 48V30AH battery that destroyed the pack, it would be a big investment straight to the garbage. A problem in one of your smaller packs would mean you still had the other. It’s not likely to happen, but it’s something to think about.

A letter from Casey Evans to Electric Bike Technologies, makers of the E-BikeKit™ electric bike conversion kit system. This one of kind adaptive electric stroller was designed by students from California State University-Sacramento using two 500w direct-drive hub motors controlled by a single E-BikeKit system. Thank you for enabling me to take my daughter hiking! My name is Casey Evans and my daughter, Montel, was born with a very rare…

Hi Micah, thank you for your advice. I am not going to touch that battery. I know this may be a lot to ask, but would you build me a battery for my velomini 1 ? It doesn’t have to be the one that fits in the frame, I could put it in a bag and hang it on the handlebars or something. If more convenient you can email me directly at dlimjr at yahoo. My sincere thanks and may you and your family have a happy holiday.. Don, San Francisco

It’s hard to say for sure without seeing your work. I imagine that either you have a bad connection somewhere, or else you have some cells that are weakened and drop their voltage too low when a load is applied. I didn’t quite understand from your message: did you rebuild the battery using the cells in your Frog battery, or did you start with new ones? Old or damaged cells could cause the problem you are experiencing.

After years development, we have built up a good reputation for high-quality lithium ion battery packs and electric bikes battery at very attractive prices. Our Quality system satisfies the international standards of ISO 9001:2008.

One other drive system that sort of splits the difference between mid drive and hub drive is the shaft drive. It works like an automobile, positioning the motor more towards the center of the bike while driving the rear wheel with a shaft. These are not very common today, perhaps because they require extremely customized frames that are not symmetrical. While a rear wheel drive truck often has a drive shaft extending from the motor (under the hood) back to the rear wheels that is located centrally under the body, a bicycle has to use one of the chain stay arms to support the shaft. This makes it look a bit awkward and perhaps difficult to service as well.

Maybe another way forward is to buy a pannier mounted supplementary battery pack (a proper one with a BMS) and to install it in parallel with the main one. The question then becomes whether to connect between the sprung terminals that go to the motor controller (which I believe to be the best thing to do) or into the little charging port jack. I presume that the charging port is connected to the charging side of the BMS and I don’t know how much current that port would take or whether it’s even a good plan to charge and discharge the main battery at the same time. I see significant potential for a high current through that small jack once I discharge via the main battery and a voltage difference exists between the supplementary batter and the main battery.

thanks for detail explanation , I was enjoj reading it. Well, I am interesting why did you pick this tipe of battery, I was thinking to use LiFePO4, I know there are usualy 3.2V it is less than 3.6V like here? Also, can you explain me how to calculate max current of battery, it says that you get 8.7Ah, but how much Ampers and what is the power of battery, how many Watts (P = U * I)? Furthermore, without welding, can I do on contact connection, like for example are battery in remote control?

Hi Frank! I used to live in San Francisco and love riding through all of those spots. Hope the city treats you well, ride safe out there. Regarding your “ideal bike” I suggest copying and pasting this question into the Help Choosing Ebikes Forum where people can share their opinions. I’d love to help but am currently traveling and trying to post new reviews with the extra time. The first thing that comes to mind is the Optibike Pioneer City which is a step-thru and uses a powerful mid-drive motor that will be excellent for climbing hills. There’s no twist throttle on this bike but the assist is very satisfying and more efficient overall. Hope this helps!

    For a complete write up on LiFePO4 care and trouble shooting read our story here. LiFePO4 cells nominal voltage is generally from 3.0-to 3.2 volts, and generally, lifepo4 is a heavier and less power dense than available LiPo batteries and is not capable of as high of amperage discharge.
