=================================================
Warning:
1. Ensure the correct battery type has been
selected prior to charging. An incorrect choice may
damage the batter y and/or become a fire hazard.
Please with caution.
2. Do not use this product to charge non-compatible
battery chemistries.
===================================
===================================
Glossary of battery terms explanation:
1, Lipo: often referred to as a lithium polymer batter y
with a nominal voltage of 3.70V and a fully charged
battery of 4.20V.
2, LiHV: often referred to as a high-voltage lithium
battery with a nominal voltage of 3.85V and a fully
charged battery of 4.35V.
3, LiFe: often referred to as iron-lithium battery, with a
nominal voltage of 3.30V and a fully charged batter y of
3.60V.
4, Lion: often referred to as a lithium-ion battery with a
@ToolkiRC 2023
Page 12
12
nominal voltage of 3.60V and a fully charged batter y of
4.10V.
5, LTO: often referred to as a lithium-ion battery with a
nominal voltage of 2.40V and a fully charged battery of
2.70V.
6, NiMh: often called NiMH battery, nominal voltage
1.20V.
7, PB: often called lead-acid battery, nominal voltage
2.00V.
==================================================
2. Cell Setting
Move the cursor to [Battery Section], then short
press the [Scroll Wheel] to modify the number of cells.
The display is as follows:
Rotate the [Scroll wheel] to adjust the value. When
@ToolkiRC 2023
Page 13
13
set to [Auto], the charger will automatically identify the
number of cells by checking the total voltage against the
balance port data. Short press the [Scroll Wheel] and
[Exit] to take effect and return to the previous interface.
===================================
Tips:
1. If the connected battery is over-discharged
or over-charged, this may cause an incorrect
cell-count, in which case the cell number needs to
be adjusted normally.
2. If the cell count is set incorrectly, it may lead to
overcharging, which can present itself as a fire risk.
3. The cell count can be more accurately
determined if the balance port is connected.
=================================
3. Work Mode
Move the cursor to [Mode] and short press the
[Scroll Wheel] to modify the work mode, as shown in the
figure below:

dissipation, maximum 3.0A@20W discharge.
2. Recycle mode: when a battery is used as the
input, the power is recovered to the input battery
through this function, max 20.0A@600W discharge.
3. External mode: when the input port is connected
to a discharge load and the output port is connected to
the battery, it can be discharged through this function.

batteries, balancing only occurs if the balance
plug is connected. The charger will
automatically balance each cell if a balance
plug is detected.
3. Charging will automatically start for the next
battery if the initial battery is disconnected after
being fully charged. If a set number of cells is
set, ensure that the subsequent cell count
matches the cell count of the initial battery. If
@ToolkiRC 2023

Other functions
1. Firmware upgrade
After connecting the M8P to the computer with the USB
cable in the box, the computer will recognize a USB
drive named Toolkit. Download the upgrade file app.upg
from the ToolkitRC website www.toolkitrc.com and
overwrite the files in the drive to upgrade the firmware.
2. Automatically continue charging/ discharging
When a battery is fully charged, connect the next
battery. The device will automatically continue to charge
and discharge, you can start and stop this function in the
settings menu
3. Fan level
When the internal temperature of the device exceeds
45°C, the fan turns at half speed to reduce noise. When
the internal temperature exceeds 53°C, the fan turns on
full-speed to enhance heat dissipation.
4. Manual voltage calibration
With the M8P powered off, press and hold the [roller].
without releasing the roller, connect the power supply,
and the system will enter the manual voltage calibration
mode. Use a voltmeter to measure the actual voltage of
each battery, move the cursor to the corresponding
voltage value, modify the voltage value to match the
voltmeter value. After the calibration is completed,
move the cursor to save, short press once, the buzzer
@ToolkiRC 2023
Page 43
