Bioenno Power BLF-12300AS User Manual

Thank you for purchasing the Bioenno Power BLF-12300AS LiFePO4 Battery

Introduction

LiFePO4 chemistry is an evolution in rechargeable battery technology. It is safer, non-toxic,
higher performing, and longer lasting compared to lead-acid batteries. Bioenno Power provides
the highest quality LiFePO4 battery from our ISO9001 certified production facility that guarantees
maximum performance. Please carefully review the information below as they are vital to the
safety and performance of the battery.

Typical Applications

- Solar energy storage
- Electric motor
- Backup power supply (UPS)
- Ham radio
- Portable electronic equipment power (audio, visual, networking, power tools etc.)
- Drop in replacement for sealed lead acid battery (SLA)

Caution
●
This battery uses a 20A charger. Please be aware when charging the battery on the same
electrical line with other devices.
●
Do not disassemble.
●
Do not short circuit positive and negative terminals.
●
Use only LiFePO4 compatible chargers. Do not use Lead Acid battery chargers.
●
Do not submerge in water, the seal on the battery is not intended to withstand water pressure
●
Do not throw in fire or dispose of improperly. Recycle the battery at a facility that accepts lithium

Instructions for Use

Charging

1. Only use 14.6V, LiFePO4 compatible chargers to charge the battery. The charging
current should not exceed 20A. 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 about 6 hours.
3. If your battery came with a Bioenno Power charger, there are two LED lights on the
charger, LED 1 and 2. LED 1 should turn red whenever a load is connected or when the
charger is plugged into the wall. During charging both LED 1 and 2 are red. When the
battery is fully charged, LED 1 will be red and LED 2 will be green.
LiFePO4 does not suffer "memory effect" so please keep the battery fully charged for daily
4.
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. Maximum Continuous Draw is 100A. Please make sure your electrical load consumes a
current less than 100A continuous and 1200 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. The
customer assumes all responsibility in the event of a series or parallel connection or connections.

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.
