Thank you for purchasing the
Bioenno Power
BLF-2440A 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

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
battery

Instructions for Use
Charging
1.
Only use
29.2V, LiFePO4 compatible
chargers to charge the battery. The charging current
should be between
4A
– 8A
. 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 3-5 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 5 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 24V 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
40A.
4.
The battery outputs a steady voltage around 25.6V 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:
This battery will not operate in series configuration.
Please do not use the battery 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.
