1. Introduction
The Range Pro X8 RP6S24KHDA is a dual 6S2P, 24,000 mAh, high density, battery pack consisting of two
independent 6S2P Lithium Ion Polymer battery packs installed in a single battery cage. The battery
packs are impedance matched at the factory, placed in a common cage, and wired independently to a
single connector.
On the aircraft the unit provides a blind mating power solution with easy insertion and extraction from
the system using a dovetail rail system and latching mechanism. The power pins from both battery
packs, though housed in the same connector, are independently routed to the aircraft power
distribution board.
For charging, power and balance port connectors are separately wired for each battery pack and broken
out for connection to a charger using a custom cable. To connect the RP6S24KHDA to the SKYRC
Ultimate Duo 400W (D400) Balance Charger, use the RPBCCA400-12 twelve-inch cable that includes a
battery mating connector on one end and two sets of power and balance ports on the other. Custom
cable lengths are available upon request.
This document provides instructions on how to customize the D400 charger for use with the
RP6S24KHDA battery as well as some common troubleshooting steps for addressing issues that may
arise when the unit is not set up correctly. For additional details on how to use the D400, refer to the
Ultimate Duo Instruction Manual provided with the charger.

*In most cases Synchronization can be set to ON but it is important to note that in rare cases
Synchronization may prevent one side or another from charging properly if there is a significant
mismatch between battery states. Also note that while Synchronization will ensure the same program is
being used by both sides of the charger, in the case of custom Battery Memory programs it does not
ensure that the programs for each channel are identical. Battery Memory programs must be
independently set on each side of the charger.

5. Troubleshooting Common Charging Errors
a. The channel times out before charging is complete
i. Error Message: OVER TIME LIMIT
ii. In the system settings,
(1) set the Safety Timer to OFF to prevent this from ever happening, OR
(2) set the Safety Timer to ON and 150 minutes
(a) Each Range Pro X8 RP6S24KHDA battery pack requires approximately 12,000 mAH
for a full charge. At 6 Amps this equates to two hours or 120 minutes.
(b) Another 30 minutes is added to support the extra time required to complete final
balancing at lower currents.
b. The channel stops charging due to an over charge capacity limit
i. Error Message: OVER CHARGE CAPACITY LIMIT
ii. In the system settings,
(1) set the Capacity Cut-Off to OFF to prevent this from ever happening, OR
(2) set the Capacity Cut-Off to ON and 12,600 mAH
(a) Each Range Pro X8 RP6S24KHDA battery pack requires approximately 12,000 mAH
for a full charge.
(b) Another 5%, or 600mAh, is added to permit support for some more extreme battery
drainage situations.
c. The channel charges batteries to 4.35V per cell
i. Error Message: None – determined when checking battery cell voltages after charging is
completed
ii. Within memory setup, anytime the BATT TYPE field is opened for editing, the TVC (Terminal
Voltage Charge) is reset to the default voltage for that battery type. The user is not
informed of this background change. If the program is then saved without ensuring the TVC
is set correctly, the memory setup will overwrite the previous setting and use the default.
(1) The custom memory program for the Range Pro X8 RP6S24KHDA battery pack uses the
LiHV setting, which has a default TVC value of 4.35 VDC.
(2) For the Range Pro X8 RP6S24KHDA battery pack the correct TVC value is 4.30 VDC.
(3) After changing the battery type and prior to charging, always confirm the TVC is set to
the correct value.
iii. Why does this resetting of the TVC sometimes happen unexpectedly?
(1) To start a charging sequence using Battery Memory 1, the user needs to PRESS & HOLD
the Enter “” key.
(2) To start editing setup for Battery Memory 1, the user needs to PRESS the Enter “”
key.
(3) If a user is not careful and, starting at the [BATT MEMORY 1] screen, presses the Enter
“” key twice in a row, the system enters edit mode for the Battery Type. Even if no
change is made in this field, the TVC is updated to match the default TVC for the battery
type selected. To prevent the default value from being saved either press BATT/PROG
“” to cancel without saving or prior to saving, adjust the TVC to the correct value.
d. The charger will only charge the battery at 0.1A and it takes a long time.
i. This can happen when a battery is significantly drained beyond normal operating voltages
and the cell voltages have fallen below a certain charging threshold.

ii. When using the LiHV model as a basis for a customized program, if the total battery voltage
is below 20.4 volts (3.4 volts per cell), the charger will only trickle charge at 0.1A until the
battery reaches the minimum voltage threshold. After all cells exceed the minimum voltage
threshold the unit will switch to charging at full current until the process nears completion.
Near the end of the charging process the current will slowly decrease as the individual cells
are finely balanced.
iii. One way to accelerate the charging process when slow charging occurs is to start charging in
the LiPO mode, being sure to set the channel to 6Amps and a 6S configuration, which has a
lower charging threshold of 19.8 (3.3 volts per cell). After the battery voltage exceeds 20.4
volts per cell switch to the customized LiHV model to obtain a full charge of 4.30 volts per
cell.
