Batt-man digital dashboard

NOTE KNOWN ISSUE:   if the Batt-man's display ever goes off and wont turn on it needs to be reset using this reset procedure: Hold down  the reset button with the button unplugged and then plug in the battery. 

This new battery gauge we are very happy with.
It has a lot of the same features as the popular Cycle Analyst but in a more condensed size and more affordable price. 
It offers many advantages over the Cycle Analyst despite being much more affordable:
  • It only has a few wires coming from it instead of the huge cluster coming out of the cycle analyst.
  • It has a built in shunt that is easier to solder than the Cycle Analyst
  • It has a compact size that is easy to mount.
  • It has an awesome mounting system that is effective and looks good

However the Batt Man has its drawbacks to the Cycle Analyst. It is not as fully featured as the Cycle Analyst so if you need functions such as temperature monitoring and shut off, low voltage cut off, PAS pedal assist functions, the Cycle Analyst is better. The Batt-Man is for the users who just need a simple to use battery gauge. 

Main screen

Batt-man digital dashboard has 3 screens:

Main screen

    • Speedometer - displays speed in the desired measurement units (km/h, mph).


    • Trip odometer - displays driving distance since it was last reset.


    • Graphical fuel gauge - a visual way to indicate how much battery power is left.

Battery meter screen

Battery meter screen

    • Current- displays the instantaneous Amperes flowing in the system.


    • Voltage- displays battery voltage.


    • Discharge- displays the accumulated Amp-hours drawn since it was last reset.


    • Power- displays the instantaneous power of the system. (* when there is no current this field shows Wh).


Peak data screen

    • Max Amps- displays the maximum recorded Amps.


    • Min Voltage- displays the minimum measured battery voltage.


    • Top speed- displays the maximum recorded speed.


    • Max Watts- displays the maximum recorded power.


Peak data screen


Batt-man digital dashboard GUI(Graphical User Interface):

Batt-man digital dashboard has a USB interface, for easy setup, logging uploads and firmware update.

Settings screen

Peak data screen


    • "Read total" - reads the accumulated values stored in Batt-man's internal flash.


    • "Reset" - resets the accumulated values stored in Batt-man's internal flash, use it when replacing a battery or installing the Batt-man on a new vehicle.



    • "Program" - sends the values selected to Batt-man's memory


    • "Read" - Reads current settings from Batt-man's memory (called automatically when connected)


    • "Wheel diameter" - set your wheel diameter or circumference, for the speedometer.


  • "Battery capacity" - set your total battery capacity (XX.XXXAh). Batt-man will use this setting to calculate the amount of charge left in the battery.

Logger screen

Peak data screen

Batt-man records the following real time values, while driving:
Voltage (red graph), Amperes (blue graph) and speed (green graph).
The logger will reset when the user resets Batt-man, you can log up to 1:30 hours of traveling.
The logger records data only when the speed is greater than zero or the discharge is greater than 300ma. The logger does not record when the device is connected to the USB.

Advanced screen

Peak data screen


  • "Upgrade firmware" - use this button to change Batt-man's firmware, when new firmware is available.


    • "Program" - sends the values selected to Batt-man's memory


    • "Read" - Reads current settings from Batt-man's memory (called automatically when connected)


    • "load defaults" - every Batt-man is manually calibrated, these default calibration settings can always be retrieved.


    • "Shunt resistance" - the value in milliohms of your shunt.(*)


    • "Shunt offset" - if your Amps reading is not 0 when there is no load, add the Amps reading to this value in order to reach 0 reading.(*)


    • "Voltage divider" - used to calibrate the voltage.(*)


    • "Voltage offset" - used to calibrate the voltage.(*)


          * Advanced users use only.



      • Maximum continuous current - 70A
      • Maximum momentary current - 160A (for less than 5 seconds)
      • Maximum voltage - 100V
      • Maximum amp hour - 65.000Ah
      • Maximum watt hour - 6500.0Wh
      • Blue backlight for night vision

      • USB interface




If display goes blank and needs reset: The procedure is to turn off the power, hold the reset button then power it up.



1. Does this replace the dashboard on my bike?



1. No, this provides a more comprehensive view of your battery packs statistics and your usage info. It does not have speed or distance capability for example. For these functions you can use any regular bicycle speedometer.

    The Batt man looks sturdy and high quality. The programming was easy. Now the hard part. As a novice I'm still figuring which wires to cut into. I'm sure i'll figure it out, but I think a top level schematic and a few words would be a worth while addition.

  2. Great products

    Posted by John Knoeller on Mar 28th 2017

    This product installed quickly
    In the program uploaded to my computer quickly
    Overall I think this is an awesome product for the price

  3. batt-man on my ebicycle

    Posted by Mario Reisch, Switzerland on Nov 14th 2016

    after some problems to make run the software on my old XP windows, i had to download NET framework v2.0.50727 and a not working usb cable, and then no display when i mounted it, i found how to reset on your homepage, (push reset when connecting to the battery) i works now perfekt and exact, i controlled with volt and ampere meter.

  4. Does the job; should have a battery reset without resetting everything else too

    Posted by Walt on Oct 20th 2016

    Compact, easily installed product. The speedometer pickup cable length should be at least a foot longer, especially if being attached to the front fork. Good mounting hardware. Be sure that you allow for enough cable slack for the entire steering radius; I pulled the cable out of my last unit by turning full left (more than I would ever steer) when parking the bike.

    What's most annoying is that if you recharge the battery, you have to do a reset to get an accurate power reading, but that also erases all other stats' history. This should be at least a two-step reset process.

  5. Screen Usually Locks Up

    Posted by Jack on Jul 17th 2016

    The Batt-Man usually locks up with a blank screen when power is applied, requiring the hold-the-reset-button-when-applying-power reset trick mentioned in the other review. Perhaps the manufacturer can fix this through a firmware update. I hope so, because holding down the button with one hand while trying to push together battery connectors with the other is a nuisance.

    I installed it without any problems, but on my 2nd ride the screen locked up. I emailed the company and they responded very quickly with a solution: Hold the reset button while powering up and it worked! I was so thrilled that it was such a simple fix.
