Alterations to the product without expressed written consent
from the manufacturer.
Please keep the battery away from water, heat sources, sparks,
and hazardous chemicals.
DO NOT puncture, drop, crush, burn, penetrate, shake, or strike
the battery.
02
Do not disassemble charger.
Do not expose charger to rain or snow.
DO NOT touch the exposed electrolyte or powder if the battery
casing is damaged.
Please make sure any battery charger(s) or charge controller(s)
are disconnected when working on the battery.
Use of an attachment not recommended or sold by the battery
charger manufacturer may result in a risk of fire, electric shock,
or injury to persons.
To reduce risk of electric shock, unplug charger from outlet
before attempting any maintenance or cleaning. Turning off
controls will not reduce this risk.
The charger outputs 10A and is intended for the use of charging
25.6V Lithium-iron phosphate (LFP, LiFePO4) batteries that can
handle the charge current.
Ensure that the LiFePO4 batteries include a PCM/BMS when
using this charger.
To reduce risk of damage to electric plug and cord, pull by plug
rather than cord when disconnecting charger.
Do not operate charger with damaged cord or plug – replace the
cord or plug immediately.
Do not operate charger if it has received a sharp blow, been
dropped, or otherwise damaged in any way.
Any uncovered battery material, such as electrolyte or powder,
that has contacted skin or the eyes must be flushed out with
plenty of clean water immediately. Seek medical attention
afterwards. Spills on clothing should be rinsed out with water.
DO NOT connect or disconnect terminals to/from the battery
without first disconnecting loads.

Renogy 10A AC to DC Charger (RBC10A2P) is an automatic and
portable charger intended for 24V LFP batteries. This charger
includes 14AWG alligator clips and outputs power based on the
power, voltage, and current condition of the battery. The charger
has an LED status indicator for providing a visual means to
determine the operating mode and condition of the battery
connected to the charger. The AC-DC portable charger will
automatically monitor and maintain the battery at full charge.

Operation
There are two ways to make the charger work normally.
1. The black alligator clip represents the negative pole, and the
red clip represents the positive pole.
2. Connect the negative alligator clip to the negative terminal on
the LFP battery, and then do the same for the positive terminal.

LED Status
LED Status Description
Solid Red
Green
OFF
Indicates that the 24V LFP battery is being
charged with a charging current range
between 1A and 10A.
There are two statuses:
1. The charger is not connected to the battery.
2. The battery is fully charged.
The specific status is subject to actual
conditions.
The LED indicator immediately goes out when
the charger triggers one of the following
protection mechanisms:
Over-current protection
Over-voltage protection
Under-voltage protection
Short-circuit protection
In this case, please follow the steps in
Troubleshooting below.

Short Circuit
Protection
Condition Steps to Take
1. When there is a short circuit between
the two poles of the ring terminals in the
battery charger, the Short Circuit
Protection will be triggered. The charger
stops working immediately, and the LED
indicator goes out.
1. When the internal temperature of the
AC charger is greater than 85(±5)℃, the
charger's Over-temperature Protection
will be triggered.
1. When the battery voltage is between
13V and 15V, the Undervoltage
Protection of the charger will be triggered.
2. The 24V battery has almost reached its
end of lifespan when its voltage drops to
a range of 13V to 15V. Please contact the
battery manufacturer for further support.
2. After the Over-temperature Protection
is triggered, the indicator light of the
charger will go out and the charging
current of the charger will immediately
drop below 6A.
2. Disconnect the connecting wire of the
AC terminal immediately. When the short
circuit between the live wire and the
neutral wire is resolved, wait for 10
seconds, and then reconnect the AC
terminal wire, and the charger will restart.

Connection
Protection
Condition Steps to Take
1. When the voltage at the output terminal
of the charger is greater than 32V, the
Overvoltage Protection will be triggered.
At this time, the indicator light will go out
and the charger will stop working.
1. When the charger triggers the Reverse
Connection Protection, the external fuse
on the connection line will blow, the
charger will not work normally.
2. Replace the fuse on the connection
line immediately. The specification of the
fuse is 250V 15A.
2. Disconnect the battery immediately
and check the charger.
