AL4830-GC2
48V 30Ah LiFePO, BATTERY
Included in the package:
1 x AL4830-GC2 Battery
1 x CAN Communication Cable
1 x User Manual
Introduction
The ALLiION AL4830-GC2 is a high performance, 48V deep cycle Lithium Iron
Phosphate (LiFePO,) battery with a capacity of 30Ah. This battery has been
designed as a lightweight, high cycle replacement for deep cycle lead acid
batteries used in 48V applications such as electric golf carts, recreational
vehicles and commercial equipment.
A remote CAN based battery monitor (AL4830- GAUGE) is available as an optional
accessory to enable remote monitoring of the battery status.
The integrated Battery Management System (BMS) ensures that battery operation
is safe and reliable over the life of the battery.
It is important that you read this User Manual before attempting to install
the battery to ensure you understand the safe operation of this battery.
Failure to do so may void your warranty.
Warnings & Safety
- Read this manual carefully before installing or using the product
- Keep the manual in a safe place so it can be referred to as required
- Any damage or injury as a result of misuse is the responsibility of the user
- The information in this manual is subject to change without notice
- Do not short circuit the battery
- Do not disassemble the battery
- Do not drop the battery
- Do not store or use battery near a heat source
- Do not connect battery to high voltage
- Do not expose battery to water or fire
- Always check polarity before connecting battery
- Do not use excessive force when attaching wires to battery terminals
- Do not expose the battery to impact or crushing force
- Do not allow the battery to remain discharged
- The battery must be installed in an upright position
- The battery must be positively retained when installed to prevent damage or short circuit
- Ensure the correct battery charger is used for charging
- If battery emits an odour, or the case becomes hot or distorted, stop using the battery
- If eyes or skin are exposed to liquid leaking from battery, wash with water and seek medical advice
Note: Battery must be installed in.an upright position
LED Status Indicator
The LED Status Indicator consists of a red and a green LED.
The red LED is used to indicate a fault, and is not illuminated during normal
operation.
The green LED is used to indicate the State of Charge (SoC) of the battery:
| SoC | Indicator |
|---|---|
| 0% – 20% | On 0.3s / Off 0.7s |
| 20%-90% | On 1s /Off 1s |
| 90%-100% | On constant |
Connecting Multiple Batteries in Parallel
Up to ten AL4830-GC2 batteries can be connected in parallel. When
connecting batteries in parallel, ensure the voltage of all batteries is
within 2V.
The wire used to connect the batteries must be sized correctly to ensure it
will support the maximum current flow of the device. It is good practise to
use wire which one size larger than required to minimize any voltage drop.
Do not connect the batteries in series.
The charging leads and power connection to the device must be connected at
opposite ends of the parallel network. This ensures any voltage drop from the
connecting wires is balanced, and ensures that power delivery and charging
current is balanced across all batteries.
Charging
It is important that the battery is kept within the nominated temperature
when being charged. A suitable charger with specific lithium battery settings
must be used to ensure safe and reliable charging.

Power Switch
The ALLION AL4830-GC2 is equipped with a power switch on the top of the
battery.
When the batteries are not being used for an extended period of time, it is
recommended that the batteries be switched off to eliminate any quiescent
drain which may discharge the battery.
