General Safety Information

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.
DO NOT open, dismantle, or modify the battery.
DO NOT touch any terminals or connectors.
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 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.
DO NOT connect or disconnect terminals to/from the battery
without first disconnecting loads.
Do not expose charger to rain or snow.
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 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.
Do not disassemble charger.
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 20A and is intended for the use of charging
12.8V 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.

General Information

Renogy 20A AC to DC Charger (RBC20A1P) is an automatic and
portable charger intended for 12V LFP batteries. This charger
includes 12AWG 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.

4.Blade Fuse (30A)

Dimensions

Operation

Never alter AC cord or plug provided on the charger.

IMPORTANT: Place the charger on a hard-flat surface. Do not place
it on a plastic, leather or textile surface.

Locate the charger as far away from the battery as DC cables permit.
Never place the charger directly above the battery being charged.
Do not operate the charger in a closed-in area or restrict the ventilation in any way.
Never allow the alligator clips to touch each other.

To get started, connect the positive alligator clip to the positive
terminal on the LFP battery. Do the same for the negative terminal.
Upon successful connection, the status indicator will display Red
or Green depending on the status of the battery.

LED Status

LED Status	Description
Solid red

This indicates the charger is charging
normally.

Always-on
green light|

There are two conditions when the
indicator light is always green.
Condition 1: When the charger is first
connected to the AC utility terminal, but
the AC charger output is not connected to
the battery (meaning the charger is in an
idle state);
Condition 2: When the charging current of
the charger is lower than 2A (meaning the
battery is fully charged).

Indicator light off|

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.

Troubleshooting

Condition	Steps to Take

Short Circuit
Protection|

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.
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.

Undervoltage
Protection|

1. When the battery voltage is between
4V and 5V, the Undervoltage Protection
of the charger will be triggered.
2. The 12V battery has almost reached its
end of lifespan when its voltage drops to a range of 4V to 5V. Please contact the
battery manufacturer for further support.

Overvoltage
Protection|

1. When the voltage at the output terminal
of the charger is greater than 16V, the
Overvoltage Protection will be triggered.
At this time, the indicator light will go out and the charger will stop working.
2. Disconnect the battery immediately
and check the charger.

Condition	Steps to Take

Reverse
Connection
Protection|

1. When the charger triggers the Reverse Connection Protection, the external fuse
on the connection line will blow, the
charger will not work normally.
**LFP batteries should not be charged below 0℃/32℉. Otherwise,
the BMS cuts off the charging.
2. Replace the fuse on the connection line immediately. The specification of the fuse is 250V 30A.
