I'm about to start a new commuter season on my EcoSmart. I noticed the batteries started to loose some of their endurance and output towards the end of the fall. They've been through about 130 charge cycles. I ride to the train about two miles with a pretty good grade in both directions. On the ride home at night, it started to run out of juice the last few weeks. So, I'm going to refurb and tweak it and need some advice.
New higher output batteries? Pluses and negatives. Options.
Upgrading from 36v to 48v? What does this affect? (There's a detailed youtube on performing this upgrade)
Bigger motor? Change sprocket?
For instance, if I went to a 750watt motor with 4 12v (48v) batteries, what would that give me?
Can I turn this frame into a speed demon that will fly up the hill and do about 25mph on the flat?
I want more torque/speed for the uphill portions of the ride. In the morning it's steep climb to a long down hill and at night after the scooter has been sitting for 9 hours it's the opposite, a long uphill grade with a short thrill ride.
The only downside to higher capacity batteries is that they will weigh a little more than the original batteries. If you upgrade to 9Ah they weigh 0.7 pounds more than 8Ah batteries so there would only be 2.1 extra pounds added though which is not a lot of weight. If you went with batteries higher than 9Ah then the footplate would need to be raised or other modification might be necessary.
An upgrade from 36 Volts to 48 Volts would increase the power and top speed of the scooter significantly however if the original 36 Volt motor was still used then it may run hotter than normal and its lifespan could be lowered depending upon how hot it got while the scooter was being driven. Overvolting the battery pack and using the original speed controller may or may not work as some Razor controllers will not work at higher Voltages than they are designed for. Some people overvolt controllers and motors and they last a long time, while other people overvolt these parts only to find them burn out in a short amount of time.
A more powerful motor with a smaller sprocket on it and a more powerful controller will result in higher top speeds and better hill climbing ability, along with good reliability so long as the gear ratio is appropriate for the motor size.
For steep hill climbs with torque and speed, horsepower is the requirement so using the most powerful motor as possible would give the best results.
Please note that only the original Ecosmart motor and controller are bolt-and-go and plug-and-play on the Ecosmart scooter and any other motor and/or controller would require custom installation and wiring to install.
Hi ESP Team,
Thanks for the input. One of my concerns is if the motor mounting needs to be modified or there is a standard bolt spacing/pattern. Looking at the replacement motors and the original, I can't tell how the upgraded motor would mount. I think my first step is to disassemble the scooter a little and see what it looks like. Regarding the gearing, do I only need to change the size of the sprocket on the motor or would we change both?
Parts List (preliminary):
Motor - 1000W MOT-481000 $130
Charger CHR-48V1.6AXLR - $50

Sprockets - not sure.
Upgrade to disc brakes?
Wiring harness parts and connectors
All in for about $400?
I have a Razor Eco-smart Metro that I recently purchased new. I'm looking to upgrade using your 1000 watt motor (MOT-481000) mated to a 48V 1000watt controller and 48V throttle. (I will be purchasing a 48V charger also. I plan on using the stock gearing since I ride mostly flat ground. I want to do this upgrade right so it is reliable. So my first question is am I on the right track as far as what I need to purchase to make this upgrade and second what batteries (model and number) do you recommend to get the optimum performance out of the swap. I don't mind raising the bamboo deck if needed. I commute less than 2.5 miles round trip to work everyday and plan to use the scooter for a daily commuter. Also do I need a different wiring harness. I will be ordering all the parts from you so any help will be greatly appreciated.
A 36 Volt 1000 Watt motor will draw around 28 Amps at full power, and a 48 Volt 1000 Watt motor will draw around 21 Amps at full power.
So for a 36 Volt 1000 Watt system three 12 volt 14Ah or 15Ah (or higher) batteries are recommended. And for a 48 Volt 1000 watt system four 12 Volt 10ah or higher batteries are recommended.
Thank you for getting back to me. I will order the parts right now. Thank you for being such an awesome place to buy the right parts at better than the right price. BTW I'm actually buying 2 of everything so I can build my wife one too. You guys have a customer for life.
Sorry to bother you guys again with what is probably a stupid question but here goes. I am about to order all the parts to upgrade my Ecosmart Metro Scooter to a 48v 1000w setup. below is the list of items i'm going to order from you. my question concerns batteries. I was wondering if instead of (4) 12v 10ah batteries I could instead use a single 48v 10ah Lithium Ion battery? I know they are more expensive but I'm told they last longer. will the Lithium Ion battery work with your controller and your 48v 1000w motor and will it be compatable with your 48v controller and 48v throttle? I like that it is a single unit.
One thing to consider though is the controller's low Voltage cutoff rating and the Lithium Ion battery's lower Voltage limit or discharging cut off Voltage. More information on this subject can be found on this page: Matching a Speed Controller to a Lithium Battery (Li-ion or LiFePO4)
so does the lithium ion battery really last longer than the lead acid batteries
thank you for the info. also Im looking for an anti-theft device or a gps tracker for my scooter, do you have a recommendation? Do you guys sell such a unit?
Hi guys its me again. I purchased everything I needed to upgrade my Ecosmart Metro to a 48v 1000watt sysstem from you. below is what I have received for the build (I'm actually building 2 Ecosmart Metro's for my wife and I) I am ready to start wiring it up but I have a question that I trust only you guys to answer. I am going to install an inline fuse for protection using a ATO inline fuse holder. My question is what amp fuse should I use, and where inline should I wire it? or would a circuit breaker be better? Im only asking you guys because I know you guys are the best at this.
2- 48v 1000watt motors
2- 1000watt controller
2 XLR 48v chargers
2-48v throttles with key switch
4 (per scooter) 12v 10ah SLA batteries.
Whether to use a fuse or circuit breaker is a great question. Both types of these circuit protection devices have their pros and cons.
In my opinion circuit breakers are the more modern and user friendly technology. However both fuses and circuit breakers provide the exact same function and either of them can be successfully used on electric scooters.
Thank you for the wonderful advice and quick response. This type of customer service is exactly why I purchase all my parts from you. Your knowledge and amazing products lead the way when it comes to how to do business the right way. I have a neighbor who is looking into purchasing a couple of scooters and I let him see your interactions with me on my projects and I also showed him your website. He was to say the least as impressed with you guys as much as I am. I'm sure he will also be a customer soon. Thank you for the help. As soon as I get the two scooters back from the body shop (they are both being painted with House of Kandy Sublime Lime paint) I will send you guys some pictures.
