followed the video about a year ago, used the kit off of ebay with the integrated volt display on the throttle, used many of the ideas in this video. Wrapped the plastic case in duct tape to avoid rocks hitting it and silver looks pretty good.
I saw one of the comment below suggesting the power drill batteries. Thats what i used and its awesome. I had so many and the charge time is 30 mins not 12 hours. I forst did a power wheels upgrade from 12v to 18v and it was amazing not just speed but run time was 3 x more. The same with these. The power is greater and run time twice the regular but best part is you just pop them out and pop one in like a drill so no down time. With 4 batteries they can run non stop all day if you have a power source to charge.
Hi do you have a step by step guide for this or a video I have a 36v 800w quad for my boy and I’m always pushing it home and time is run short we need to be out all day not half hour 🤣🤣
2 - 36volt 10s 4P ''10 amp'' Lithium packs in parallel, with built in BMS, would rock on this !! , Might need a 1000 watt motor & 15amp ESC though .. Plan on doing that to a Mega moto E -1000 minibike, & using 2 chargers, to charge each pack separate. 2 of these packs weigh about the same as 1 - 12 volt lead acid battery, weight savings is over 66 % !! Will also be making a parallel harness using 12 g ''R/C type'' Silicone insulation wire & XT - 90 connectors. Lastly, will be running 2 LED ''mini'' battery monitors, one for each pack plugged into the charge leads, * mounted in a frame on the handle bar cross bar. Run time & performance ''am guessing'',, should go up at least 20-25 % I74
I did this upgrade on two quads at the same time and after a couple months the break no longer auto shuts off the motor when applied? Any thoughts on if I need to get a new break or if it is the controller?
Batteries in the link too wide, not the thinner ones in your video. Can’t put 3 side by side in one container and still fit. Where can I find the ones you used? And are they 36volt12v12ah?
what's the run time? just bought my 4 year old one, and the 36 volt razor dirt bike. seems like they need to be charged every 10 minutes, is that right?
The kids typically ride until they move onto something else in our situation. It never actually went dead on on riding situation but they would normally ride for 20-30 min at the time.
Awesome video! Thanks for sharing the idea. I'm planning you use one ryobio 40v battery, they are actually 36v. would you please give the the link for that kits. thanks in advance.
I did the upgrade Run much faster however When I plug in for charge, the charger light still green all the time. Any idea what I did wrong? So no Charge at all, please help me..
Do you think using a 40v power tool battery and adapter instead of big sla will be more cost effective for the duration? 6ah 40v are around $85 on amazon and adapters are $20. Mounting the adapter in an easy to get to place will allow for quick swapping, and I have a couple of ryobi 5ahs for my yard tools I can have in reserve.
how about replacing the 12v batteries for power tool batteries. like two Milwaukee 18v batteries in series. less weight. faster charges. just not sure on how long they would last.
It's about amp hours. Unless you want to pay way more for Milwaukee 9amp or 12amp batteries than what you can just buy the 12V for. The reality is that the extra power puts too much demand on the motor and gears. You need to get the power adjustment and inline fuse. My kid trax dodge ram blows the fuse when my boy and his little sister are both in it going up even a slight hill even I have the juice turned up. There is a website that has upgraded parts stage IV is under $300 with battery and everything you need. Upgraded metal gears, motor, batteries...
www.mltoys.com/category-s/138.htm There is the site for upgrades. Just search for 12v battery and look for the highest amp hour for run time. I've seen 30+ amp hour but the batteries get massive
For my birthday I’m going to ask for a razor street bike and I’m wondering if I can put a 36v speed controller with 2 24v batteries and stock motor. Can I do that?
I added a 36V Li-Ion with original Controller and it works. But does anyone know if the original Motor can handle 180 pound man climb a hill in grass? Have you rode your sons quad? Mine is able to move a adult around flat land and downhill fast. But struggles badly to climb any inclines. It might need just the Controller or also a 750 Watt Motor to move 180 ibs...? Please lmk if it climbs with adult weight? Thank you
In the long run much cheaper to buy a lithium ion battery (over 1,000 charge cycles), and much more run time, and faster charging time. I got one for $108 on ebay.
