Description

The LiFePO4 (LFP) chemistry and the nominal voltage of 12.8 V bring the pack close to 12 V lead-acid models in voltage, and the cycle life is stated as over 3500 cycles. The BMS is mounted inside the case, so a separate protection and monitoring module is not needed, and the pack is connected like an ordinary battery. The specification lists ISO 9001, UL and FCC certificates. The capacity is not given in the page data and is taken from the pack marking or the datasheet. For comparison, the lead-acid series of the same catalog have a service life of up to 10–15 years (FML up to 10 years, GEL up to 20 years in float mode), but it is counted in years, not in cycles. A pack of this type is convenient in UPS and float systems, where lead batteries have to be replaced often.

How to choose

If you are replacing 12 V lead-acid blocks (FML, FMH, GEL) with lithium ones, make sure the charger has a profile for LiFePO4. Connecting packs in series raises the voltage and connecting them in parallel increases the capacity, so the number and the scheme are chosen to suit the bus voltage and the energy reserve you need, for example for a UPS.

FAQ

What are the chemistry and voltage of these batteries?

Lithium iron phosphate chemistry, LiFePO4, with a nominal voltage of 12.8 V.

What cycle life is stated for the LFP pack?

Over 3500 charge and discharge cycles.

Is a separate BMS needed for this pack?

No, the BMS is built into the pack, so a separate protection and monitoring module is not needed, and the connection is made as for an ordinary battery.

Which certificates are listed for the battery?

ISO 9001, UL and FCC.

Can an LFP pack replace a 12 V lead-acid block?

At 12.8 V the pack is close to 12 V models in voltage, but the charger must support the LiFePO4 profile.
