Bioenno Power BLF-1260AS User manual

Thank you for purchasing the Bioenno Power BLF-1260AS 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.

Caution
●Do not disassemble.
●Do not short circuit positive and negative terminals.
●Use only LiFePO4 compatible chargers. Do not use Lead Acid battery chargers, especially ones
with “anti-sulfation” features
●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 be about 10A-15A. 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.
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 60A. Please make sure your electrical load
consumes a current less than 60A continuous and 720 watts of power.
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.

Troubleshooting
Since the battery can be used in many different configurations and equipment, we cannot provide
a general troubleshooting guide. Please contact us so a technician can provide you with
individualized support.
FAQ
Q. The terminals/connectors on the battery do not fit my application, what do I do?
A. You can change the terminal/connector to whatever type you need without voiding the warranty
so long as you do not open the battery or modify the casing.
Q. I have a universal lead acid charger with high charging current, can I use it instead?
A. Not recommended. Lead acid battery charges at 2.30V to 2.45V per cell whereas LiFePO4
needs 3.60V per cell. Your battery would be undercharged so you won’t get full capacity nor
will balancing be triggered, both of which are not desired. Furthermore, the floating charge of the
lead acid charger is not expected by the battery and can cause problems.
Q. How come the battery stops working a few seconds after a high current draw?
A. Make sure the load is not exceeding the rated continuous output current else the PCM shuts off
the battery after 2 sec. To reset, disconnect the load and attach the charger for a few seconds.
If you need more current output, please contact us for an exchange or a custom solution.
Q.Can I buy another of the same LiFePO4 battery to double the voltage or capacity?
A. Not recommended. Refer to the series and parallel connection section. You should always get a
single battery that meets your voltage and capacity requirements to avoid problems.
Q. I need more help with the battery I bought?
A. Please contact us using the information below.
