USER GUIDELINE
LITHIUM IRON PHOSPHATE BATTERY
High Voltage!—Do not touch
any terminals or connectors to
avoid electric shock!
While working with Lithium
Iron batteries, always wear
protective clothing and eye
glasses
Any uncovered battery
material such as electrolyte or
powder on skin or clothing
must be flushed out with plenty
of clean water immediately!
Seek medical attention
afterwards
Terminals of Lithium Iron
phosphate batteries are
always live, therefore do not
place tools on them, do not
short circuit or use outside of
the specified electrical ratings
Safety Precautions
• To protect all electrical equipment, circuit breakers, fuses, or disconnects should be utilized. They should
all be appropriately sized by a certified electrician, licensed installers, or regional code authorities. The
Renogy LFP contains a BMS that protects the cells from over-charge, over-discharge, and excessive load
amperages, however this alone will not protect your system from severe electrical conditions.
• When connecting wiring, verify proper polarity positions. Never short circuit the battery! This can cause
bursts of amperage which can irreversibly damage your system or battery and lead to possible explosion.
• Use safety clothing when installing the battery.
• Do NOT string this battery in series. It is made ONLY for parallel connections using identical batteries.
• Connecting the battery in series or parallel with another battery will result in catastrophic failure.
Note: Make sure to tightly screw the battery terminals in, having loose battery terminals will cause the
terminals to build up heat resulting in damage to the battery.
Storing Batteries
• Batteries should be stored at room temperature, charged to about 30%-50% of capacity. It is
recommended to charge the batteries once every three months to prevent over-discharge.
• Long periods of storage can deteriorate battery performance because of lack of use.
Standard Charge / Discharge
• Standard Charge shall consist of charging at 0.2C constant current rate until the battery reaches 14.6V.
The battery shall then be charged at a constant voltage of 14.6V while tapering the charge current.
Charging will terminate when the charging current has tapered to a 0.02CA. Charge Time is approximately
7 hours. Safe Charging consists of temperatures between 32 ºF and 113 ºF.
• Battery Standard Discharge is constant current of 0.2C to 10V.
• Charge batteries before use.
