Rad Bikes have upgraded their battery packs using Samsung cells. Their battery is now rated at 48V and 14 AH. Just tossing that out there. Thanks for the vid.
Yep they do. I may not have upgraded if they had those when I did this. But, I do like having the 52V. When my 52v battery is dying, it still has as much or more punch than the 48v does when its on a full charge. The new 48v 14ah batteries are about 15% smaller than this one I installed still, because of the voltage differences.
Here is a thought and what I am considering. Somehow mount the stock battery holder to the rear rack on the deck so I can still use panniers. Split the main connector with a switch mounted to the handlebars or down on the downtube somewhere. Ride out one battery until its low, flip the switch and instantly keep going on the other battery. Why not put the 500 dollar battery that came with the bike to use ? :) would only add about 5 bucks to mod your set up this way versus buying another 500 dollar battery.
I agree, that would be a great option and not very hard to do. The reason I am not doing anything like that is because I'm converting my wife's bike to an ebike and using my stock RadRover battery on her bike. But what you described would be a great option for a 2 battery setup.
I like this idea - I have a Rad Rover was planning on buying one of the new 14A batteries, and just carrying the old one in my rear rack bag and swapping them out manually when I drain the first one. Your suggestion would only require purchasing an additional battery holder and a simple switch. I'll probably do this - thanks!
Thanks for posting ... from Bill about to replace my 2017 RadRover battery that is showing signs of aging. Nice to see how easy it can be to go for a 52 volt battery.
I saw the 52v dolphin pack from Luna cycles. You think that would slide right on to the stock down tube bracket? Also the the controller can handle 52v correct?? I have a radcity, I must have forgot to lock it and I hit a bump and the battery launched off. It turns on and charges, but it won't power my bike. I don't a triangle battery for aesthetic purposes. Would be nice to just slide the new 52v pack right on. I have no experience with electricity. Thanks for the video!!
I have a ebike with 48v battery, and I want to set up second 52v battery. Also I want to set up switches for each battery. I also want to install the switches for each battery so that I can switch it off when one of the batteries is discharged. Can you explain me how to do it properly?
Great. video and explanation. Now I am wanting to know more about your solar power system and how it works to store the electricity into the batteries. Do you have any videos on that?
Do you know if the stock controller can handle 52v batteries? I plugged mine in and I had no motor power then the screen went haywire and it completely died and won't turn back on.
I had a 52v on the stock controller for almost 2 years with no issues. So, yes it should work. Mine is a 2017 model though. I don't thing they changed much though after mine.
You should have gotten a higher capacity pack. You upgraded, but only a little. You could have spent a little more, and made it worth wile. Your idea with the switch, and both packs is a good one. If the packs were the same volts, you could have parallel connected them for mega range. I am looking at the same battery, but the 31.5 Amp Hour size..
ok so you upgraded battery, upped stocked speed through settings, now the thing I'm having is wanting to upgrade the calipers to some shimano's with some new brake disk, I working with a rad mini, you feel like you want to upgrade yours. also have you thought about trailer hitch that acts like a rolling book bag when unhooked.
I think a hydro brake upgrade will be my first upgrade other than tires. Definitely interested in a 52v battery upgrade too. Luna has a direct replacement....a no brainer.
Thanks for your information! Regarding the solar charging, did you use a modified or pure sine wave inverter? Wondering if my current modified sine wave inverter would damage the bike battery charger?
It was just a cheap modified inverter. It has worked great for many things. I have a nicer pure sine wave inverter for my camper, but for chargers and other things, I haven't seen any issues using the cheaper inverter. So far anyway :) You can see the difference if you plug a TV or radio in, there can be some feedback from the cheaper inverter. But that has been the only time I have noticed.
No, you can up the volts and amps completely separate. It depends on if the new battery has the cells in series or parallel. Parallel will up the amps only, series will increase the voltage only. Add both together (amps+volts) to get the total watts.
You have increased the power, Watts, to over the legal limit, but traffic officers would not know or care. They probably would be happy if you kept the speed below 25 while pedaling. I know it is 20mph, but when pedaling, you can legally push it faster, especially down hill. The officer does not know how hard you pedal, but hit 30 with those fat tires and it would be obvious you've jucid it too much.
Thanks for the video. Have you had any issues with error codes or excessive heat? Also, now that you've had some time to test it with the new battery, what would you say the range is now? Thank you in advance.
Hey man great video thank you ! I'm just wondering if you can take a look at the Emojo Wildcat ebike and tell me where you think the controller is because I have no idea .... I want to upgrade to a 52v battery but I need to make sure the controller can handle it first
Will this battery give me more speed/power/torque, if the motor/controller are stock ? Also, if I mount the stock battery on the rear rack will the wires reach the controller ?
No, the speed is governed by the computer. But you can change that setting. I uploaded the video on how to increase the max speed: ruclips.net/video/YBaKiNl8DUs/видео.html
No, I still have it. I'm planning on putting it on my wife's bike when I convert her bike to an ebike. There are other batteries available that will be a direct fit for your Rad Bike. Check out the dolphin battery packs. They should slide right into your bike's battery mount.
Thanks for the tutorial. I can see you know your way around electronics. In your video narration you mentioned that the voltage increase shouldn't affect the controller and then you mentioned amperage. Your new battery is listed at 15AH, but the stock battery provided by Rad Power Bikes is listed as 11.6AH. Maybe you could give me a quick lesson about amps. By watching your video I picked up a link to 'CaliBike'...thanks...never heard of them. Looking at CaliBike's website I noticed they had a 48V/20AH battery pack for only $30 more than the 52V/15AH. It's my belief that the more AH you have the longer battery life you have. Are you saying that those 4 extra volts will provide more power? I suspect your going deer hunting and want a reliable transport. Maybe consider a narrow two-wheel trailer? But then again, I suppose just putting a deer on the bike and using the bikes built-in-walk-feature would be reliable and safe. I didn't realize the price of solar panels are more affordable. 2x4's and framing brackets seem to be the way to go for a simple solar array.
@007vsMagua, Thanks for the comments. Lets see if I can answer some of your questions. For the controllers on our bikes, they are limited usually by amperage. The max amperage of my controller is set to 22 amps. This is the amount of current it is able to pull from the battery. Amperage is what causes heat, which is something that can fry motors and electronics. Increasing the voltage doesn't increase the heat like increasing the amperage would. The max voltage I believe the controller can take is just over 60v, but I cannot recall for sure right now. its more than just the 4 volts. You have higher volts all the way through the discharge. The 52v battery will charge to 58.8v, and discharge to 42v. The stock battery will discharge to about 38v, and starts at 54v fully charged. I have noticed I have more power the entire time, where with the stock battery you could really tell when it was getting low. The higher the volts, the faster the motor will spin. Unfortunately, the 20AH battery was not available when I ordered my battery. Otherwise I would have purchased one of those. However, the 15ah battery is a very tight fit on my RadRover. I'm not sure if the 20AH battery would fit inside the frame. It may have to be mounted on the bike rack if it doesn't fit. Hope this reply was clear enough. I don't have time to look up resources for clarification. If you have any other questions let me know and I'll have more time tonight to reply.
Thanks Tony, Glad you liked it. It was worth the upgrade for me. Definitely has more punch and it lasts much longer. I rode it for 25 miles total today on a single charge, and it was still going strong.
F6Family Vlog does the controller have a capacitor that can blow up ?Haha I know the motor can handle it of course just didn't know enough about the controller
I have read of other people using a Dolphin 52v battery going many miles without any issues. I've put 25 miles so far with no issues. I'll still cross my fingers though :)

If the buyer knows anything about these bikes he will know the battery was changed either way. I have since heat shrink-wrapped the wires now, so this is a non-issue. Thanks for watching.
Your in the Seattle area, well I'm in spokane.. NICE VIDEO I gave you a sub hit me back with one.. ok was the 52 volt worth the extra cash, did you gain speed and range and if so how much. Thank you..

You missed the other points of having a higher power battery pack. By the time this 52V battery dies, it still has more power (more torque, speed) than the 48v battery has. I don't have to worry about lugging another battery with me. I purchased this for hunting. The less weight I take with me the better. I also am using the other battery for a ebike I'm building for my wife. I needed to purchase a battery either way. :) Worked out great for me. Carrying a spare might be a good option for you though.

Does ungrading make it faster then 40km or do you need to change the controller for that
So what speed can you get the bike up to now with the 52v 15A battery ?
How. Much was the battery
How dose it work I have the same bike but the miter is rated to 500watts

The stock controller can handle 60v so 52v fully charged is around 58 I believe.

Can you also use a 52 volt 20 AMP system on the rad ? And do you only use the black and red wire.? What about the bms on the new pack?

I would humbly like to add that technically, Watts is Amps multiplied by Volts (W=I*V)
@@f7familyvlog704 A*V=W If you up just the A or just the V then W will go up: 746W=1HP.

No issues at all after about 50 miles. The range is probably close to 30 miles without pedaling, but I always pedal so its further for me.
That's great Glenn. Thanks for the update.
Can you do a video on how to upgrade a RadCity 2018 Battery?

is 54V battery OK for the 48v Kit
Yes
I would just but another battery for double the range
speed > range
Will this battery give me more speed/power/torque, if the motor/controller are stock ? Also, if I mount the stock battery on the rear rack will the wires reach the controller ?
does the increase allow for speeds over the 20 mph or mostly all duration?
