LFP BATTERY
SFK-275HP
Lithium Iron Phosphate
LFP or Lithium Iron Phosphate is one of the safest lithium based chemistries in the market. Unlike other
chemistries such as Li-Ion or Li-polymer these batteries do not have thermal run-away, and will not ignite
or burst into flames (in rare circumstances, if the cell is punctured; the electrolyte is flammable and may
ignite) if overcharged / over discharged. It is the only chemistry recommended for recreational use and
has been confirmed to be the safest lithium option by independent labs and government agencies (
https://www.fire.tc.faa.gov/pdf/TC-16-17.pdf).
Sun Fun Kits LifePo4 batteries may be used anywhere typical deep cycle lead acid/agm/flooded batter-
ies are used and do not require special charging equipment as they have built in circuitry that ensures
proper charging and discharging. It is recommended that you use lithium LifePo4 chargers whenever
possible, or set your charging apparatus to the AGM charging profile to ensure that your batteries can get
fully charged. Sun Fun Kits offers the
(https://www.sunfunkits.com/product/21/sun-fun-kits-
136v-330-watt-lithium-charger-lifepo4 ) charger that can be used to fully charge your LifePo4 batteries for
customers looking for a stand-alone wall outlet charger. Acceptable uses are:
04
Use in RVs as a 12-48 volt power source, or as part of an inverter bank to provide standby power
Use in solar panel installs as a power source for storing power
Use in troller motor applications for boats (requires ensuring that the battery is isolated and protect-
ed from water intrusion)
Use in Golf Carts or other small electric vehicles that have amperage governors (care must be tak-
en to ensure that the batters are protected from water intrusion)
