Help! How to Increase the Mileage in 1000w 48V 10ah ebike ?

[bharath2050]

Hello!


I recently modified my fatbike to a ebike. I got kit from alibaba and battery here it self.

Here is the specs:

1000w motor
26A controller
48V 10ah Battery


Problem: I'm not getting good mileage... I'm hardly getting around 15-18 km which is very bad.

I searched in net for the solution and found that we can set the parameters in lcd screen. The problem is I don't know which value to set to get good mileage.

So please help me guys!! Please....

Thanks
Bharath

Without more details of exactly what your bike and your motor system are, and the terrain you ride in and speeds you ride at, etc., I can only suggest these:

--Leave battery on charger all the time you are not using it
--Increase air pressure in tires
--pedal more
--slow down
--add another battery in parallel, or get a larger, higher-C-rate battery.

Yeah, I can get ~130km out of my 10ah 88.8V battery if I ride slow enough and pedal with the motor. Or ~16km if I ride wot at 70kph. if you're riding full throttle, then 15-18km doesn't sound that bad for a 10ah 48V pack. Cut your speed in half and you'll get 4 times the range.

Your range is exactly right for going fast. For longer distance at that speed, 40kph or more, you will have to buy more battery.

Are you getting that distance going 25 kph? If so, your battery is pretty darn poor. at 25 kph, you should be getting more like 30-35k.

No doubt they told you when you bought it, 40k range. Yes,, it will, going slow enough. They like to say 35kph, and 40k range. They did not say, 40 k range AT 35kph. Nearly all do that, and they suck for it. The company I work for gives range in a spread. so we'll say 15-25 miles range, and top speed 27 mph. The high range number is not even based on the lowest power setting the bike has, but one for going about 12 mph.

So,, make sure your battery is fully charged, sometimes it takes a few cycles to fully balance it and get 100% charged. Charge full, ride around the block, charge full again. Sometimes this can get you one AH more capacity.

Then either slow down, or get a second battery if you need 25 k at 35 kph.

Likely you can turn down the max amps on the LCD. I'd just turn the throttle less, because sometimes you want the full power, like for hills.

Most of the better kits have a power setting adjuster on the LCD, that you can turn up or down easily as you ride. This type I will ride in low power for better distance, but then I can still beep it a few times, and have full power when I need it.

I'd suggest you get an in line watt meter for about 50 dollars and attempt to figure out what total wattage your bike is supplying. try and get one which counts the total amp hours. Energy can only be lost as heat, and if you are losing 2-3Ah, then that would be enough to keep your controller/motor very hot. if you measure the Ah used using a watt's up type meter, from hobbyking, ebay, amazon, etc, you will know what your battery is giving you. Check your battery carefully, if it was not made for 1000w it could be overheating, so measure the little wires on it or put meltable plastic on either side of hte batteries and check if it gets holes in it.

Go slower
Pedal harder

The tires you're running play a HUGE part of how much mileage you're going to get. You need to get your hands on a low rolling resistance tire and your world will change. Here's a link to one such tire that I've personally used and can attest to their higher speeds and lower rolling resistance. I use them in cross country races and they make a huge difference. I all but guarantee they'll help your mileage, esp if you're running a big nobby tire at the moment.

2.2" tires will look funny on 4-5" rims. Fat tires are inherently less efficient since they're heavy, usually run at lower pressures and wider so more traction (everything else being equal). I'd consider different, narrower wheels and tires.

I run this on the rear of my half fat bike with 39mm rims, but people have run them without issue on 100mm rims. Read the reviews.

I love this tire for street use. I put them on my motorized Mongoose Dolomite with 26x4" rims. It has a much smoother ride than the original off road knobby 4" tires, and They look great too.
I was originally concerned that the sidewalls might rub going around corners putting a 3" tire on a 4" rim, but it's not even close to being a problem. They inflated perfectly with the original Mongoose tube.
