Congratulations on your choice of SkyRC B6 Nex!
B6 Nex comes with both AC and DC power input, which can
meet you on power supply in dierent circumstances.
Multiple protections are implemented to maximize safety,
such as reverse polarity protection, charging time limit,
overcharge capacity limit.
The operation of a multi-chemistry battery charger does
require specic knowledge on the part of the user. BE SURE
to read these INSTRUCTIONS, WARNING, and SAFETY NOTES
before you use the charger. Danger can occur, including re
or explosion, due to misoperations.
We hope you have years of pleasure and success with the

The free SkyCharger app unleashes tons of features and
advanced settings, which tremendously enhance the
experience of B6 Nex.
With the balance lead connected, B6 Nex will balance your
lithium batteries while charging or discharging.
App Control (iOS and Android)
Internal Independent Lithium Battery Balancer
B6 Nex is adaptable to various types of batteries, such as
LiPo, NiMH, Pb, and LiHV batteries.
With highly optimized software, the preset modes can meet
various charging purposes: FAST charge reduces the
charging time, whereas STORGE controls the battery's
terminal voltage to the best state to maximize its lifespan.
Adaptable to Various Types of Batteries
Fast and Storage Mode for Lithium Battery
1 to 5 cycles of continuous process of charge>discharge or
discharge>charge is to refresh and balance the battery for
an extended lifespan.

The charging capacity is calculated as the charging current
multiplied by time. If the calculated capacity exceeds the limit,
the process will be terminated automatically when the
maximum value is set.
Capacity Limit*
You can limit the maximum process time to avoid any
potential defect.
Experienced users or experts can set Charge or Discharge
Terminal Voltage according to their needs.

These warnings and safety notes are vitally important.
Please follow the instructions for maximum safety;
otherwise, the charger and the battery can be damaged, or
at worst, it can cause a re.
Never leave the charger unattended when it is connect-
ed to its power supply. If any malfunction is found,
TERMINATE THE PROCESS AT ONCE and refer to the
operations manual.
Keep the charger well away from dust, dampness, rain,
heat, direct sunlight, and vibration. Never drop it.
The allowable DC input voltage is 10~30V. AC input
voltage is 100-240V.
This charger and the battery should be put on a heat-re-
sistant, noninammable, and nonconductive surface.
Never place them on a car seat, carpet, or similar. Keep all
the inammable or volatile materials away from the
operating area.
Make sure you know the specications of the battery to
be charged or discharged to ensure it meets the require-
ments of this charger. If the program is set up incorrectly,
the battery and charger may be damaged. It can cause
re or explosion due to overcharging.

WARNING AND SAFETY NOTES
B6 Nex 07·

A battery pack which consists of dierent types of cells
(including dierent manufacturers);
A battery that is already fully charged or just slightly
discharged;
Non-rechargeable batteries (Explosion hazard);
Batteries that require a dierent charge technique;
A faulty or damaged battery;
A battery with a built-in charging circuit or protection
circuit;
Batteries installed inside a device or which are wired to
other components;
Batteries that the battery manufacturer does not express-
ly state suitable for the charging current this charger can
deliver.
Have you selected the appropriate program suitable for
the battery type you are charging?
Have you set up adequate current for charging or
discharging?
NEVER ATTEMPT TO CHARGE OR DISCHARGE THE FOLLOW
ING TYPES OF BATTERIES:
PLEASE BEAR IN MIND THE FOLLOWING POINTS BEFORE
COMMENCING CHARGING:
WARNING AND SAFETY NOTES
B6 Nex08·

Have you checked the battery voltage? Lithium battery
packs can be wired in parallel and series, i.e., a two-cell
pack can be 3.7V (in parallel) or 7.4V (in series).
Have you checked that all connections are rm and
secure?
Make sure there are no intermittent connections at any
point.
During the charging process, a specic quantity of
electrical energy is fed into the battery. This quantity is
calculated by multiplying charge current by charge time.
The maximum permissible charge current varies depend-
ing on the battery type or its performance and can be
found in the battery manufacturer's technical specication.
CHARGING
WARNING AND SAFETY NOTES
B6 Nex 09·

Only batteries expressly stated to be capable of FAST charge
can be charged at rates higher than the standard charge
current. Connect the battery to the charger's terminal: red is
positive and black is negative. Due to the resistance
dierence between the cable and connector, the charger
can not detect resistance of the battery pack. The charger's
essential requirement to work properly is that the charge
lead should be of adequate conductor cross-section, and
high-quality connectors, which are normally gold-plated,
should be tted on both ends.
Always refer to the manual by the battery manufacturer for
the charging methods, recommended charging current and
charging time. Especially, the lithium battery should be
charged according to the charging instructions by the
manufacturer strictly.
Do not attempt to disassemble the battery pack arbitrarily.
Please get highlighted that lithium battery packs can be
wired in parallel and series. In parallel, the battery's capacity
is calculated by multiplying a single battery capacity by the
number of cells with total voltage stay the same. The
voltages imbalance may cause re or explosion. Lithium
battery is recommended to charge in series.
WARNING AND SAFETY NOTES
B6 Nex10·

The main purpose of discharging is to clear the battery's
residual capacity or reduce the voltage to a dened level.
The same attention should be paid to the discharging
process as charging. The nal discharge voltage should be
set correctly to avoid deep-discharging. The lithium battery
can not be discharged to lower than the minimum voltage,
or it will cause a rapid loss of capacity or a total failure.
Generally, a lithium battery doesn't need to be discharged.
Please pay attention to the minimum voltage to protect the
lithium battery. Some rechargeable batteries have a memory
eect. If they are partly used and recharged before the full
charge is accomplished, they remember this and will only
use that part of their capacity next time. This is called a
memory eect. It is said that NiCd and NiMH batteries are
suering from memory eects. NiCd has more memory
eect than NiMH.
DISCHARGING
WARNING AND SAFETY NOTES
B6 Nex 11·

Choose AC or DC power input: the maximum power that B6
Nex can deliver is 50W via AC input(100-240V), whereas the
charger can deliver up to 200W through DC input(10-30V).
1. Connect the charger to a DC power supply or power on
the device via an AC outlet.

2. Insert the battery to the charger
Connect the charger to Pb battery.
To take advantage of B6 Nex’s full power capability, the power source should
be 10-30V DC, and output power should be 220W or higher.
A low-quality DC power source may damage your B6 nano charger.
