Thanks. I've already got M12 batteries so this is what I'm building for my night rides! Great idea.

Thanks for sharing this Mike. I have recently built two systems after watching your version 1 video. My mountain bike has the spot/flood light bar with the battery inside my 45Nrth pogies. The same setup on my fat bike but with a JW Speaker work light at the moment. Less obnoxious for commuting but not as bright. I am looking at tapping into the batteries for heated clothing as it gets a bit chilly on my commute in Edmonton. Great videos, Mike. Well produced and the right level of detail.

I'm making one using LEDs I've got from a TV. Im going to make another one using a regular light bulb, I'll just have to make some modifications on the LEDs to acomodate less than 12v. I'm also using 18650 batteries with the booster.

Thanks, very helpful

Awesome video. Hard to acquire the parts in Europe and harder to do it in Dutch. Thanks for inspiration.

I never thought of putting the charger components on the back of the battery pack. I've been researching how to build one from scratch, wich is a big pain for a newbie. Thanks for the info

Nice. These mini light bars draw around 0.9 to 1.2 amps. You need a battery that can withstand that draw. Drill batteries work and a good quality 18650 will also. I did try some generic/lowcost/dollar store 18650 and they could not handle the draw.

very well done, thank you! :-)

Hey, can you make tutorial like this using the batteries of motor? Just for lights.

Hi there. You can also use a step up boost converter,. Some have a low voltage protector so the batteries won't discharge below the charging voltage. When you connect the batteries in series you're increasing the voltage, but when you connect them in parallel you're increasing the amperage which means you double or triple the running time.

@MikeFreda

You can but it needs to be a pretty large one. Most of the small step up chip boards like the XL6009 won’t work. I’ve tried. They do not like the current these light draw. Their specs are miss leading. If you wire these batteries in 12v configuration you can use one of those 3 cell / 12V BMS chips. I’ve come up with a different solution. Please have a look at my version 3 light.

Great video, just what i was looking for. Do you think i could use a 4S 14.8V Lipo battery with this?

THanks for sharing the vid! I'm rocking the flood only light and it does great for me. I do wonder if i would prefer the spot/ flood combo light more. If you're into RC hobbies, LIPO batteries work great and are easy to recharge. just make sure you don't drain them too low or you'll damage the battery. I run a low voltage beeper ($3) on my batteries when i'm using them for my headlight.

Hello Mike ! Thanks for this second video. I'm curious about using a dynamo to charge the batteries. What do you think about it ?

@MikeFreda

3 жыл бұрын

I guess it is possible to charge as you ride. You would need a dynamo with high current output and voltage regulator. Typical Li-ion battery chargers require ~600mA for 2 batteries to charge. It also takes a couple hours to change these batteries from completely dead.

You should be able to put the batteries in series to obtain higher voltage. That being said you don't want to exceed or even come close to the maximum current draw of these batteries. A BMS would be good idea. cheers

I did this with a regular rechargeable 5v battery pack, step up converter with USB and DC on the ends, and solder or crimp a dc female on the light. Way easier and cheaper.

@MikeFreda

Yes, that is another way of doing it. You just want to make sure the converter is rated for the current. These mini light bars draw at least 1amp. For safety, I would get a converter rated for at least 1.5 to 2 amps. You also need to house it so it won’t get wet but not overheat.

@Pianiste221

A problem with your setup would be the efficiency loss, since the powerbank is probably just doing a step up from the li-ion inside or lipo to 5v and then you're doing it again from 5v to 9-14v, which is not ideal if you want your light to use more of the battery, you would be better of just buying a QC3 powerbank and use a QC trigger board, or just make a 3s battery like this one.

Hi, how many watts is the light? How long does it last?

That particular light bar featured in the video is 1100 lumens, 18 Watts of LED (which is the equivalent of ~65-70W of Halogen) At 12 volts this light draw just under 1 amp. With the 2300mah battery this light has a run time of ~2.25 - 2.5 hrs.

If your power bank can produce 10-14vdc, then yes. If not you may need to install a step-up circuit board. They are pretty inexpensive.

You can but for a lighting load it’s not that crucial. Motor load act differently on batteries when the battery gets low. Yes, it can help extend the life of your battery if you always run the battery until it is dead. It is another piece of hardware in the system that can fail and I don’t feel it is needed when used in this sort of setup.

Hey, It depends on the battery rating and the current draw. Not all 18650 are the same unfortunately. I purchased quality Samsung INR18650-26H (2600mAh) Basically at 3.6V it should last 2.5hrs on a 1 amp draw. Three of these wired in series will be 10.8V. If you try to run the light in the video you will probably draw 1.3 to 1.4 amps at 10.8V. I suspect this light would last ~2hrs. (at 14V this light draws around 1 amp) I hope that helps?

can you light it using powerbank?

Not really. These lights run on 9-24v. They like 12-14v. Power banks typically output 5volts. If you did you would need to have some sort of step-up break out board.

I wish you talked more about the power system , How many cells are too much ? I went with a 20v light pod from Amazon I used 5 cells I took out of old chargers in my collection , i go about an hour . So I'm wondering how can I get 4 hours , should I add 6 to 8 cells or get one of those ebike batteries . I'm not sure how to calculate and tune my system . I know how to build it lol . A person commented their test results on the review page and it says 1.4 Amps at 12.5 v , 8.8 watts per led . So I'm not sure where to go , I see some 12v water bottle batteries and some more expensive e bike ones for say around 34v systems , I'm not sure how much is just right for my lights. My pod is rated at 2000 lumens and it's perfect for the trails ,I loved its illumination but it didn't last , I usually do rides ride 2 to 4 hours throughout the year and would love to start building cheap and effective lighting solutions

Thanks for reaching out and commenting. This topic could be a complete video itself. I did touch on it a bit in my two videos. The issue is that not all lights are the same. They all draw a bit different current and not all batteries are created equally. Four hours of run time on light like this will require good batteries Some lights have a optimal voltage it prefers, yes, the may be able to use different voltages but you have to determine what is the optimal voltage for the light you are using. What you need to do is actually measure the lights current draw at whatever voltage you chose to use. Take a multi-meter and measure the lights current draw. I would try 12V, 18V, 20V. See what it draws at each voltage and how bright the light is. On my light, it draws 0.950 amps at 12Volts. So, in my case, to run 4hrs I would need a 4-5amp/hr battery. On my first light I made, I just carried a spare 12V drill batteries and would swap once it died. On my second light, I got 3 high quality 18650 Batteries. They are 3.7v batteries and wired in series. The light drawing 0.950 amps at 12V gives me 3hrs of solid run time. These batteries are rated for 2600maH batteries. Meaning at 2.6amps it should last an hour… At a lower amperage draw, it should last longer. You could do the same set up but get 6 and install them in a Series/Parallel configuration and you should be able to get 4-5 hours out of it.

A dedicated switch won’t really do that for you unless you can re-wire the light to turn off separate LEDs. Running lower voltage will dim the light a but then you are actually switching the battery configuration. You could have a separate switch to change the voltage and another switch to turn the light on an off.

Overall life span or burn/ride time? These batteries are designed for discharging and charging. Like a Laptop, I'm sure they will last many, many years before they won't hold a charge anymore. As for ride time. Over all ride time is different than burn time. This light bar draws exactly 1 amp @ 11.5V (I measured it) A 2600m amp/hour (2.6amps) batteries should give you ~2.5hrs of light on (burn) time if you just use 3 of these batteries in series (as shown). Since most people take breaks when they ride you can turn the light off when resting.... I can see you doing a 3+ hour night ride without any issues. That's along night ride.
