Instructions for Use

Charging

1. Only use 14.6V, LiFePO4 compatible chargers to charge the battery. The charging

current should be between 2A to 3A. If you need a charger, please contact us.

2. Fully charge the battery before first use. This depends on the output of the charger but is

typically between 1-2 hours.

3. If your battery came with a Bioenno Power charger, please note that the LED light on the

battery does NOT indicate the state of charge. A red LED light means the battery is

under constant current(CC) charging and green LED means constant voltage(CV)

charging. Always charge for at least 2 hours to ensure full capacity.

4. LiFePO4 does not suffer “memory effect” so please keep the battery fully charged for daily

use. Cell balancing only occurs when the battery is fully charged (top-end balancing).

5. Do not charge the battery in temperatures below 0°C. This can cause damage to the cells.

Discharging

1. Make sure your load accepts 12V nominal voltage.

2. Ensure the connection between the battery and the load can handle the current draw.

Please consult references for the appropriate wire type.

3. The maximum continuous discharge current is 6A. Please make sure your electrical load

consumes a current less than 6A continuous and 72 watts of power.

4. The battery outputs a steady voltage around 12.8V until very little capacity remain, do

NOT rely on voltage as an indicator of remaining capacity.

Series and Parallel Connection

We do not recommend using our LiFePO4 batteries in series or parallel connection if a single

battery of equivalent size can be used instead. The PCM/BMS built into each battery is intended

only for operation with a single battery and we do not guarantee the operability of multiple

batteries in series or parallel configuration. Please take the information below into consideration if

you must use a series or parallel configuration.

Series: Each battery must be charged separately, all batteries should be fully charged

before connecting in series.

Parallel: Only connect batteries with equal state of charge in parallel. Also, measure the

internal resistance of each battery and only use batteries with closely matched internal

resistance. It is highly recommended that resistors be used to achieve equal internal

resistance among multiple batteries. It is also highly recommended to add fuse(s) to

the circuit for safety reasons.

Please keep in mind a series or parallel connection can fail with a number of consequences, from

early cut off to possibly a fire. Always exercise caution and observe closely at all times.

Maintenance and Storage

The battery requires no manual maintenance due to the included PCM/BMS. However, please

follow the below guideline for best life cycle.

1. Even though the LiFePO4 chemistry is relatively stable, protect the battery from shocks

and drops to prevent internal short circuit.

2. For long term storage, fully charge the battery and then discharge to 50% of the full

capacity. Do NOT leave the battery unattended for more than 6 months.

3. For the best life cycle, avoid using the battery in extreme temperatures and avoid highly

variable pulsing loads.

This document describes the Bioenno Power BLF-1203W LiFePO4 Battery, a portable power solution designed for a variety of applications. It highlights the advantages of LiFePO4 chemistry over traditional lead-acid batteries, emphasizing safety, non-toxicity, higher performance, and longer lifespan. The battery is manufactured in an ISO9001 certified facility, ensuring quality and reliability.

Function Description

The Bioenno Power BLF-1203W is a 12V, 3Ah LiFePO4 battery intended as a versatile power source. It serves as a drop-in replacement for lead-acid batteries in many scenarios, offering a more advanced and efficient alternative. The battery is equipped with a Protection Circuit Module (PCM) or Battery Management System (BMS) that provides essential safeguards against overcharge, overdischarge, overcurrent, and temperature fluctuations, as well as cell balancing. This integrated system ensures the battery operates within safe parameters and contributes to its longevity.

The battery is designed to deliver a steady voltage output, typically around 12.8V, throughout most of its discharge cycle. This consistent power delivery is a key advantage for sensitive electronics and applications where stable voltage is crucial. Unlike lead-acid batteries, LiFePO4 batteries do not suffer from a "memory effect," meaning they can be charged or discharged at any point without degrading their capacity. This flexibility makes them highly suitable for daily use and applications requiring frequent charging cycles.

Usage Features

The BLF-1203W battery is suitable for a wide range of typical applications. These include solar energy storage systems, providing reliable power for off-grid setups or backup. It can power electric motors, making it useful for small electric vehicles or portable tools. As a backup power supply (UPS), it offers a dependable source of power during outages. Ham radio enthusiasts can utilize it for portable operations, benefiting from its lightweight and consistent output. It is also ideal for powering various portable electronic equipment such as audio devices, visual equipment, networking gear, and power tools. Additionally, it can be used for LED lighting solutions, offering an efficient and long-lasting power source.

For charging, it is crucial to use only 14.6V, LiFePO4 compatible chargers. The charging current should be between 2A to 3A. The battery should be fully charged before its first use, which typically takes 1-2 hours depending on the charger's output. If a Bioenno Power charger is used, the LED light on the battery indicates charging status (red for constant current, green for constant voltage) rather than state of charge. It is recommended to charge for at least 2 hours to ensure full capacity. Charging should not occur in temperatures below 0°C to prevent cell damage.

When discharging, users must ensure their load accepts 12V nominal voltage. The connection between the battery and the load must be capable of handling the current draw. The maximum continuous discharge current is 6A, and users must ensure their electrical load consumes less than this amount continuously, or 72 watts of power. It is important not to rely on voltage as an indicator of remaining capacity, as the battery maintains a steady voltage until very little capacity is left. If the battery stops working after a high current draw, it indicates the load exceeded the rated continuous output current, causing the PCM to shut off the battery. To reset, the load should be disconnected, and the charger attached for a few seconds.

The manual advises against using these LiFePO4 batteries in series or parallel connections if a single battery of equivalent size can be used instead, as the integrated PCM/BMS is designed for single-battery operation. However, if such configurations are necessary, specific precautions must be taken. For series connections, each battery must be charged separately and fully before connecting. For parallel connections, only batteries with an equal state of charge and closely matched internal resistance should be used. Resistors are recommended to equalize internal resistance, and fuses should be added for safety. Users are cautioned that series or parallel connections can lead to early cut-off or even fire, emphasizing the need for extreme caution and close monitoring.

Maintenance Features

The Bioenno Power BLF-1203W battery requires no manual maintenance due to its integrated PCM/BMS, which handles internal management. However, following specific guidelines can significantly extend its lifespan.

Users should avoid disassembling the battery, short-circuiting its positive and negative terminals, or throwing it into fire. The battery is not sealed, so it should not be exposed to the environment. Proper recycling at a facility that accepts lithium batteries is recommended for disposal.

To protect the battery from internal short circuits, it should be safeguarded from shocks and drops, even though LiFePO4 chemistry is relatively stable. For long-term storage, the battery should be fully charged and then discharged to 50% of its full capacity. It should not be left unattended for more than 6 months in storage. For optimal lifespan, it is best to avoid using the battery in extreme temperatures and with highly variable pulsing loads.

The terminals/connectors on the battery can be changed to suit specific applications without voiding the warranty, provided the battery is not opened or its casing modified. This offers flexibility for users to adapt the battery to their existing setups.
