There is an E-Bike light that I would like to use on my bike, which is a regular pedaling bicycle without a motor. This company does make a USB battery-powered model, the Axendo 60 USB, but it is not available for sale in North America.

Is it possible to mount a battery on my bike, which can connect to this light?

Voltage: 6-36 V DC

Thank you.

In theory, yes. You can build a battery pack with 18650 cells and holder, some nickel strips, a rocker switch, battery level indicator, BMS board, and DC jack plus whatever cable and connector the light needs. You will also need a Li-ion recharger. Use a spot welder to connect up the batteries in series with the nickel strips to get the correct voltage required. Use your 3D printer to make an enclosure that will fit on your bike.

Note: Make sure to spend a little extra and buy branded cells from Panasonic, Samsung or LG. They will cost much more, but the no brand ones are just factory rejects from the big guys that didn’t meet spec that’s why they’re cheap.

Depending on how big a battery pack you want this DIY project will be around $50 for all the materials. There are many fine bicycle lights near this price range you can buy.

You can buy a battery pack like this one on eBay from a US seller for $14 or get the same pack from a China based source for $10 on eBay. This way you can choose your own quality batteries and either recharge them in the case with an 8.4 V charger or remove them and charge them in a standard 18650 charger. You don't have to do any soldering to connect them together. Personally I hate separate battery packs and only use lights either with internal batteries or removable batteries as with one headlight that uses two 18650 batteries and can be charged in the light with 5V USB or remove the batteries and charge them out of the light.




I wonder how efficient this light may be. Since it is run off a separate battery intended for use on an e-bike it may not have been designed for efficiency. It might drain smaller batteries rather quickly even with the best batteries such as NCR-Panasonic 3,400 mAh.

FYI: Don’t use a soldering iron to connect batteries, it will make them too hot and ruin them. Use a spot welder.

Thank you for your replies to my post.
I'd like something which I can buy, ready to use. I imagine that four (4) AA batteries will be drained too quickly by an E-Bike light. Spanninga also sells a 100 Lux E-Bike light, with one LED. The 80 Lux has two LEDs. I'll buy whichever one has the wider beam spread.

Is the EBike subforum here a good place to ask this same question? I don't want to violate any rules by cross-posting.

Thanks to everyone for your replies.
Can a moderator please move this thread to the Electric Bikes forum?
Thanks again.

I have not seen too many great e bike lights. I bet you can find a light built for the job that will be more practical to use.

Get a dynamo (SON is what I would recommend) and the Busch and Müller IQ-X which is 100lux and nice and bright and easy to see. I love that light and it is much sleeker than the Spanninga stuff with a good beam pattern.

I use a non-battery headlight with a car jump starter battery pack. it also runs my taillights, flashers, and side marker lights.

my battery pack isn't available anymore, but something like this:
https://www.amazon.com/GOOLOO-18000m.../dp/B0748D8KT6
It has a 5.5mm 12 volt 10 amp output. Most of the jump starter packs don't have the 12volt/10amp port, and some are much lower amperage, but many do. Look for the 12v/10A rating.
