Display upgrade for Magnum Scout

Hi All. I have a Magnum Scout with a 750w Bafang hub motor. My current display looks similar to other models of ebike. I find navigation through the screens a bit cumbersome. The other issue I have is a very broad battery indicator.

I would prefer a battery indicator that shows in a numeral percentage, rather than 5 blocks of a battery symbol.

When I look at other displays available, some have 3 pin or 5 pin connectors. Mine is a 5 pin.

Is it safe to assume any 5 pin Bafang display will work?
 
  1. Good question "Does your bike have "Real 750W" motor?" I assume you refer to the RadRover 750w is actually a 500w motor scenario. Bummer..
  2. The following copy&paste is from one of my many thread postings over on the M2S ebike forum; [[An additional update for the following info: I currently have this simple device on 2 of my ebikes. I had it on three ebikes, but I removed one and adapted it to use on any ebike battery (I currently own 7 batteries) via wire-and-wire insertion into the battery "+" and"-" holes.]] LCD monitor for voltage/battery % remaining: The M2S computer display unit (CDU) display will show “188%” when you first power up the ebike. It quickly disappears. The owners manual/ quick reference placard states: “ *188% & DST need BMS support. Not currently available “.. Give Me A Break.. It's not rocket science and we are not NASA. Lets face it ,I've grown tired of the inaccuracy of the 5-bar “battery remaining” displayed on the cdu. You know, if I go 20 miles before bar #5 disappears, that should mean that I will be able to go a total of 100 miles before bar #1 goes away (5 bars, each @20 mp bar= 100 miles total). In other words, linear dissipation-- BUT NO, it is not to be!! Now, whenever a bar disappears, I'll just light up the ole LCD and see what it says in regards to “% of battery remaining” . Those ebike factory computer displays SHOULD be able to give better/more concise % readout information-- lord only knows that there is a multitude of other bull$hit information readily available within their “menu” pages. Anyway, for the next 1,000 miles I'll evaluate the accuracy/potential of this small Battery Capacity Indicator monitor. https://www.amazon.com/Icstation-Ca...=B07CHM3NHH&psc=1&refRID=CFCSECQBAEFSP1J5NT4E
    SideNote: the actual display has green background with black digits/battery outline-- the reverse of what is shown on the internet.
    I have installed this on the red stem ebike. It is directly below the ebikes computer display screen. This little monitor is more of a curiosity satisfy-er than anything else. Since I do not use the M2S factory installed headlight, I have some extra power wires just hanging around-- so, I hooked them up to this little rascal just for yitz n' wrenz. Ya don't even need to cut/splice any wiring because the headlight wires have the female end of the connection-- just insert the little LCDs wires into them and U B stylin'.
    Instead of needing to press a button on the LCDs display box, I only need to press-and-hold (for 2 seconds) the “+” button on my ebikes computer. Doing so “turns on” the ebike headlight/computer display unit backlight, thus ALSO illuminating the LCD display for 10 seconds before it automatically shuts off (it may then be necessary to again quick- press the + button to activate the green LCD display). After checking the LCDs “battery% / volts” I then have to manually turn off the headlight/computer display unit (cdu) backlight.
    I have already discovered that the little LCDs “type battery” selection, as shown in the paper/website instructions, is completely BOGUS-- there is not even a “li” (for lithium) selection option. So, since I have 2 batteries of identical spec's, I went on my daily ride and ran the 48v 16ah black battery down to “1 battery bar” and then continued on for another 4 miles. It never started blinking/flashing, indicating that the battery was VERY SOON to be completely exhausted, but it couldn't have been too much farther. Now I was back to the condo with two batteries; 1 was 100% freshly charged and 1 was just about out of juice. Now it was just a matter of inserting the red(+) and black (-) wires into the battery holes and then going thru the little LCD monitors' menu and seeing which setting shows “100%” and “53.4 volts” when reading the fresh battery and then swapping out for the nearly exhausted battery to get a logical reading from it. JACKPOT!! Eventually I got a low battery display of “4%” and “44.0 volts”. I WIN!! I did the swap out thing 3 times just to be sure. The menu setting of “12C” is the winner for the 16ah battery pack] So, if you want to invest in this lil' monitor toy, you are now very far ahead of the game as far as installation/setup are concerned. Also, during battery recharging, during its 4.5 hour refilling, I can check the monitor to see what it reads as battery% and voltage are increased. Sure nuff, both items show a gradual increase as the recharging progresses. I'll be installing one on WhiteyFord, too because toyz iz toyz. The little LCD monitor only weighs about as much as a bunny fart, so using Gorilla HeavyDuty duct tape to connect it to the bottom of the ebikes cdu display is a piece of cake-- plus, if you need access to the back of the monitor, just flip it up and over. Too cool.
    I will give you an update when I post the “10,000 mile” thread in a few months.
  3. ADDENDUM on Jan 1, 2020: If you buy this type led monitor, you may as well go ahead and buy this connector, too E-flite Y-Harness, HD 6" (2): Universal Light Kit, EFLA617. It is actually used for radio controlled airplane lighting systems. I broke one of the wires at the male connecter (the wires are very fragile/delicate) and had to do ALOT of searching to find the correct type harness. The added bonus with this particular harness is that it a 2 male plugs AND the package contains 2 sets of wiring AND the wires are twice is thick as those included with the lcd monitor. Thats all for now.
  4. Finally, the photos below are the dashboard display on my 2021 ArielRider X52 beast. It uses a 52v/18ah battery system, thus the "info" shown is for that type/size battery. You can see the accuracy correlation between "max-min" info on distance traveled, battery voltage/battery percentage, etc. Hope all this info/data helps you.
