Higher-Current Charging — Up to 3A
The ACC-17V3A-LED provides a maximum output current of approximately
2.8A to 3.0A, making it a useful charging option
for compatible medium- and larger-capacity lithium-ion battery packs.
A higher available charging current can shorten charging time compared
with a lower-current charger, provided the battery is designed to accept
that charging current.
For example, a compatible 10Ah battery may charge faster using a 3A charger
than using a 1.8A charger, although actual charging time depends on
battery condition, starting charge level, temperature, and the
battery's charging-current limitations.
Important:
The charger's 3A rating is its maximum available charging current.
It does not mean every battery will charge at 3A.
Use this charger only when the battery manufacturer permits the
specified charging voltage and current.
Smart MCU-Controlled Three-Stage Charging
The ACC-17V3A-LED uses a microcontroller (MCU) to manage
an automated three-stage charging process.
-
Pre-Charge Stage:
A reduced charging current may be applied when appropriate,
helping manage the initial charging process.
-
Main Charging Stage:
The charger supplies controlled charging current,
up to its rated maximum, while battery voltage increases.
-
Final Charging and Termination:
The charger completes the charging process and automatically
terminates charging output when its completion criteria are met.
This automated process is designed for compatible lithium-ion battery
packs and is different from simply connecting a battery to an ordinary
fixed-voltage AC power adapter.
Four LED Charge-Level Indicators
One of the most useful features of this charger is its
four-LED charging-progress display.
Instead of showing only a basic charging or fully charged status,
the LED display provides an approximate indication of charging
progress in 25% increments.
| LED Display |
Approximate Charging Progress |
| 1 LED |
Approximately 25% |
| 2 LEDs |
Approximately 50% |
| 3 LEDs |
Approximately 75% |
| 4 LEDs |
Approximately 100% |
The four LEDs indicate the charger's estimated charging progress;
they are not a precision battery fuel gauge.
Understanding the LED Display
The charger includes a power indicator and four charging-progress LEDs.
The published indicator instructions identify these conditions:
- Power Indicator On: AC input power is present.
- Charging LEDs: Show approximate charging progress.
- All Charging LEDs Flashing: May indicate reversed battery polarity or a shorted output.
- All Charging LEDs Off: May indicate no battery is connected.
If an abnormal LED pattern appears, disconnect the charger
and verify battery polarity, connector compatibility, and battery condition
before attempting to charge again.
Compatible 14.4V / 14.8V Lithium-Ion Batteries
This charger is intended for compatible lithium-ion battery packs
with four series-connected cell groups, commonly described as
4S lithium-ion batteries.
Typical compatible battery configurations may include:
- 4S2P lithium-ion battery packs
- 4S3P lithium-ion battery packs
- 4S4P lithium-ion battery packs
- Other compatible 4S lithium-ion battery configurations
The original product specifications describe a battery capacity
range of approximately 3Ah to 20Ah, or roughly
50Wh to 300Wh, depending on battery voltage
and configuration.
Battery capacity alone does not establish compatibility.
The battery must accept the charger's charging-voltage range,
charging current, connector dimensions, and polarity.
Charging Voltage Compatibility
The published charger output is 16.8V-17V DC.
A standard 4S lithium-ion battery generally has a maximum
charging voltage of 16.8V.
Use this charger only with batteries whose manufacturer
permits the charger's actual regulated output voltage.
Do not assume compatibility with every battery labeled
14.4V or 14.8V.
5.5 x 2.5mm DC Barrel Charging Connector
The charger includes a male DC barrel connector with:
- Outer Diameter: 5.5mm
- Inner Diameter: 2.5mm
- Barrel Length: Approximately 12mm
The male barrel connector has a hollow center with internal
spring contacts designed to grip the center pin of the
corresponding female DC jack.
It does not have a projecting center pin.
Before connecting the charger, confirm that the battery uses
a matching 5.5 x 2.5mm female charging jack
and the correct connector polarity.
Optional Connector Tips for Other Barrel Sizes
BiXPower offers optional C-series connector tips that can adapt
the charger's 5.5 x 2.5mm barrel plug to certain other DC
connector sizes.
Examples include:
Connector tips change physical connector dimensions only.
They do not change the charger's output voltage or charging current.
Always verify battery charging requirements and polarity.
Optional tips are sold separately unless expressly included
in the selected product package.
Built-In Charging Safety Protections
The ACC-17V3A-LED includes the following published protections:
- Overvoltage Protection: Helps protect against abnormal voltage conditions.
- Short-Circuit Protection: Helps protect the charger during output short-circuit conditions.
- Polarity-Error Protection: Helps protect against incorrect output polarity connections.
- Overpower Protection: Helps protect against excessive power demand.
These protections do not make an incompatible battery safe to charge.
Use only batteries with suitable internal battery protection
and charging provisions.
Worldwide 100-240V AC Input
The charger supports 100-240V AC, 50/60Hz,
allowing use with compatible electrical supplies in the United States
and many international locations.
Its portable design makes it convenient for workshops,
professional video production, field equipment, and
other applications requiring rechargeable lithium-ion batteries.
A suitable plug adapter may be required outside North America.
