THANK YOU

SFK-300HP Lithium Iron Phosphate

Thank you for purchasing your Sun Fun Kits battery kit system, your battery has been hand built by Sun

Fun Kits technicians in our Baton Rouge (Louisiana, USA) facility using components from China, United

States, and India. We have tested your battery by performing a complete balance, capacity, and load test

to ensure it is built to industry standards. Your battery comes ready to use and we recommend you review

this manual on how to get the optimum performance and longevity of your unit.

We have built the SFK-300HP battery to be serviceable and upgradeable, this allows for efﬁcient service

and repairs and ensures product longevity. The nature of kit built products comes with some consider-

ations; they are not as rugged as non serviceable products so care needs to be given when handling bat-

tery kits. However non serviceable products generally have to be disposed of in case of issues (regardless

of how insigniﬁcant) this contributes to e-waste and is against many right to repair laws; because of this

we feel our kit approach offers the best in reliability and longevity for our customers.

Please review this usage manual before using your battery/kit to ensure many years of reliable use. NOTE:

The battery will arrive with approximately 35% SOC (state of charge) and should be charged to 80-100%

before use. This is necessary to comply with shipping regulations; see the charging section for details.

Introduction:

OVERVIEW

The SFK-300HP is a high performance battery made with LF304 certiﬁed automotive grade cells by EVE

POWER. Under optimal conditions, it can provide up to 3000 cycles at a depth of discharge of 80% and

has an expected life cycle of about 10-12 years. Below we highlight some of the core features of this unit:

SFK-300HP Lithium Iron Phosphate

Made in the USA with domestic and globally sourced components in our facility in Baton Rouge,

Louisiana.

Made with CERTIFIED AUTOMOTIVE GRADE cells. Every cell in our batteries has its full au-

tomotive grade report on its label and this can also be viewed on our websiteby logging into your

account. Sun Fun Kits batteries DO NOT use reject / failed / grade B cells in their construction as is

the case with practically all batteries coming straight from China and being sold online by retailers.

Upgradable and serviceable, features a tongue & groove construction to allow for sealing the lid to

the body for marine use (can be done with permanent or removable sealant).

USA 8 year warranty including all support, service, and repair in the USA.

Introduction:

CONSTRUCTION

4.0 kilowatts of reliable lithium power, replaces up to 6 lead acid / agm batteries (100ah) and is de-

signed to be fully utilized 0-100%

2.0 kilowatts of peak power, and 1500 watts of continuous power. Using Amp Boost, max output

increases to 2.2 kilowatts with 200 amp discharge.

Expected cycle life of 3000 cycles at 80% depth of discharge, and up to 5000 cycles at 50% depth

of discharge, 10-12 year usage life.

Introduction:

PERFORMANCE

SFK-300HP Lithium Iron Phosphate

Fully compatible with existing 12v infrastructure including standard 12v lead acid/agm battery char-

gers, trickle chargers and high voltage DC systems up to 48v (when in 4s series conﬁguration).

High and low temperature protection including built in heating pads to allow for low temperature

charging.

Automatic low/high voltage cut-off to stop battery damage from occurring.

Automatic short circuit prevention as well as overcharge and over discharge prevention.

Only 57lbs, one of the lightest watt / pound batteries on the market.

The battery can be monitored via bluetooth and has apps for Apple IOS & Google Android; view

the status of charge, the health of your cells, power output, temperature readings and more.

Users can adjust battery parameters such as setting up power output limits, max/min soc, turn the

battery on or off via a software switch and also set up pin code protected access to the battery.

View the combined output of multiple batteries using multi-view; supports up to 4 batteries at the

same time.

Coming Soon: Wireless to inverter communication, send battery information to many inverter

makes & models such as: Victron, Voltronix (MMPT Solar, EG4, PowMR, Growatt, Renogy), Magnum

energy and more.

Before you begin:

SAFETY

Sun Fun Kits recommends an experienced electrician setup your battery bank system, or you have exten-

sive knowledge and experience in setting up high power DC systems. Setting up batteries improperly can

result in severe injury and even death. Please take caution when working with our batteries and ensure you

have proper safety equipment and tools, please follow these safety tips:

Wear safety equipment and tools including eye protection, insulating gloves, and use electrically

safe tools.

The use of proper circuit breakers, fuses and DC disconnects is recommended. Please ensure

installs and setups are done by certiﬁed electricians, or licensed installers/dealers.

Sun Fun Kits SFK-300HP battery contains a battery management system (BMS) that protects the

battery from overcharging, discharging and temperature extremes. Users must ensure their electri-

cal setup works within these parameters and assume that the BMS protection is secondary protec-

tion ONLY.

Reverse Polarity can cause damage to your battery, ENSURE you have properly set up your electri-

cal wiring.

Battery short-circuits can damage your bms and battery, ensure you are using insulated tools when

installing the battery and that you have planned your install carefully before beginning.

SFK-300HP Lithium Iron Phosphate

Ensure bolts are tightened and installed correctly on all cables and power

disconnections/bridges, loose terminals can cause permanent damage and lead to electrical ﬁres

as it increases resistance in an electrical circuit.

ALWAYS ensure the battery is oriented properly and has the terminals facing up. DO NOT place the

battery upside down or on its sides. This will cause permanent damage to your battery.

Keep away from direct sunlight and water, these battery units are not water sealed in order to make

them serviceable. If you are using them in a situation where they are exposed to the elements, you

must take appropriate measures to ensure they are isolated from these environmental factors.

General Usage:

LFP BATTERY

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 exposed to an ignition source). 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 (FAA trans-

portation study 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 batteries

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.

SFK-300HP Lithium Iron Phosphate

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)

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.

Sun Fun Kits offers the SFK-PS-330 (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 custom-

ers looking for a stand-alone wall outlet charger.
