Product description

M7 is a multifunctional tool chain product that
integrates functions such as a balanced charger and
discharger , an electric display, a signal measuring device,
and a signal source.

 Can charge and discharge and balance
management of LiPo, LiHV, LiFe Lion 1-6S, NiMh
1-16S, PB 1-10S batteries

 Charge current：MAX 10A @MAX200W

 Discharge current：

Recycle mode Max 10A@200W

Inter mode Max 3A @10W

 Lithium battery cut-off voltage can be set (TVC
function)

 Can measure battery voltage, battery internal
resistance, lithium battery balance management

 Can measure the signal value of PWM/PPM/SBUS,
with an accuracy of 1 microsecond

 Can output PWM/PPM/SBUS standard signals with
an accuracy of 1 microsecond@ToolkiRC 2021 7

 Constant current and constant voltage source
output, customizable 1-28V constant voltage, 1-10A
constant current

 Can be adapted to mainstream drone batteries,
automatically activated and charged

 Multi-language system, you can upgrade any
language you need

 USB 2.1A@5.0V output, rechargeable mobile
devices

 The device is simulated as a U disk, and the
upgrade file is copied to realize the product
firmware upgrade

Other functions

1. Firmware upgrade

After connecting the M7 to the computer with the USB data cable in the box, the computer will recognize a U
disk named T oolkit. Download the upgrade file app.upg
on the official website and overwrite the files in the U
disk to upgrade the firmware.

2. USB 5.0V output

In addition to the above upgrade functions, the USB
interface can also output 2.0A current to charge mobile
devices.

3. Automatically continue charging and discharging
When a battery is fully charged, after unplugging the
battery for 2 seconds, connect to the next battery, the
device will automatically continue to charge and
discharge, you can start and stop this function in the
settings menu

4. Fan level

When the internal temperature of the device exceeds
45°C, the fan turns on half-speed air volume to reduce
noise. When the internal temperature exceeds 53°C, the
fan turns on full-speed air volume to enhance heat
dissipation.

6. Manually calibrate the voltage

In the shutdown state, press and hold the [roller]
without releasing, connect the power supply, and the
system will enter the manual voltage calibration function.
Use a voltmeter to measure the actual voltage of each
battery, move the cursor to the corresponding voltage

value, modify the voltage value to be consistent with the@ToolkiRC 2021 44
voltmeter value, and achieve calibration. After the
calibration is completed, move the cursor to save, short
press once, the buzzer will beep once, the save is
successful. Just exit or shut down

7, fully charged

When the lithium battery is fully charged, it will
prompt “Fast charge is done”. If the battery is not
removed, the constant voltage trickle charge will be
performed automatically to make the battery reach a
more full state.
