SFK-275HP
Lithium Iron Phosphate
05
As a DC power source for power supplies and other items needing DC power
Use in DC to AC inverters where standby / backup power is needed such as data
centers, or residential power sources.
Usage Restrictions:
SAFE MODE
Lithium Iron Phosphate batteries are not recommended for applications that require high amperage
bursts such as starting engines or use in DC arc welding. This will trigger the maximum amp cut-off in the
batteries built in BMS (battery management system) to stop sending current and the system will engage in
a 30 second shut down.
If you exceed the amp limit of your battery or have gone to below 0% SOC and find that the battery is not
outputting power, it may be because the battery has gone into safe mode. Safe mode protects the battery
from damage and requires a cool down period of up to 5 minutes before it can be available for use again.
In order to take out the battery of safe mode, you will need to apply an external power source of 13 volts or
higher to “wake up” the battery, this can be done using any standard 12v charger.
Usage Restrictions:
MAX AMPS & VOLTAGE
Sun Fun Kits SFK-275HP batteries can be connected in parallel or in series. You can connect up to
4 batteries in series to achieve a maximum voltage of 58 volts (this is generally shown as 48v,
the nominal reading) and you can parallel these batteries up to 4 units. Regardless of how you
configure your batteries, we recommend you keep your combined power output to under 4,000
