Every SFK-300HP has its UNIQUE manufacturer test report and cell data on the battery. TRY IT OUT! Scan the QR code on this image with your phone and you will see the capacity tests, manufacture date, IR and voltage values as well as batch ids of each cell used in your battery. Sun Fun Kits batteries use Certified Automotive Grade Cells.
The SFK-200V2 BMS is the heart of the SFK-300HP. A smart BMS that features 3 temperature probes, heating element support, powerful BMS management apps (Android & IOS), up to 2.6KW maximum duty, low/high voltage protection, support for 48v (4s) in series, and an intelligent nuvoton MCU.
All Sun Fun Kits products & batteries are built, warrantied, and supported in the USA in our facility in Baton Rouge, Louisiana. You will not need to call overseas in the middle of the night to get help, contact us or any of our growing list of dealers to help resolve any of your issues.
The SFK-300HP is one of the very few batteries on the market that can be connected in series up to 48V while also including functionality to allow for low temperature self heating. You can also parallel your batteries with up to 4 units (bus bars are needed to ensure proper balancing).
Sun Fun Kits batteries are designed to be serviceable and upgradable which means you can easily change components or service your battery; but you won't have to worry about this because you're covered for 8 years with our USA warranty (60 months full replacement, and 36 months prorated).
High quality silicone rubber heating pads ensure your SFK-300HP stays nice and warm during cold weather charging. The system is automatic and does not require jumper cables or switches. Simply set the minimum required temperature in the SFK BMS app and your battery will begin to heat itself so you can charge your battery safely.
The Sun Fun Kits Smart BMS allows you to configure your batteries to suit your needs. Use Multi-View to see the combined output of multiple batteries, set charge and discharge limits in tools, or benchmark your battery to see its performance.
The lightest battery in it's class at only 57.75 Lbs., while also having the smallest possible footprint.
Bespoke Construction using purpose built casings, not generic space wasting molds common form many Asian brands.
The SFK-300HP has 6 heating modes :
Automatic Low Temp Charging, and 5 manual pre-conditioning heating modes (with the external switch).
Coupled with Sun Fun Kits insulated jacket, it makes the SFK-300HP the ultimate cold weather battery.
Sun Fun Kits presents: The SFK-300HP Self heated lithium iron phosphate battery! Yes the lightest and most energy dense LFP battery on the market that also features built in heating elements for low temperature charging, a 200A bms, support for 4s series (48v) connections, and an easy to use smart app that allows you to monitor a single or up to 4 batteries simultaneously!
The GEN 2 switch gives users greater control over their battery kit as now the Bluetooth system can be turned on or off with a touch of the button giving increased security. Users also are now able to fully manage the build in active balancer, as it can be set to run in normal mode, or in hi-mode (here the active balancer will only turn on when the battery is over 13.3 volts), or it can be turned off entirely and the battery will use the built in passive BMS balancer to manage the cells. Finally we have simplified the heating system as now users can turn heating on or off with one button; the system will indicate a white LED letting users the heating system is active and in standby, but will turn to a red LED to let users know that the system is active and is providing heating to warm up the cells. Please note, the SFK battery kits are the only kits on the market that support both standby heating as well as automatic low temperature heating, many smart batteries only support 1 mode.
Built with certified automotive grade cells with complete manufacturer test reports, you will love the reliability of EV class cells that will stay in balance, hold voltage during heavy loads, and also have the power to output up to 2400 watts to power up even the most demanding of devices.
The SFK-300HP is hand built by Sun Fun Kits technicians in Baton Rouge, Louisiana and is built to order. This battery uses components from the United Sates, China and India and has gone through 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 the user guide on how to get the optimum performance and longevity of your unit.
The SFK-300HP battery may be used anywhere typical deep cycle lead acid/agm/flooded batteries are used and does not require special charging equipment as they have built in circuitry that ensures proper charging and discharging.
