SMART ACTIVE BALANCE ENDURANCE BATTERY LITHIUM IRON PHOSPHATE 12V 275 AH 3.6 KWH

Sun Fun Kits presents: The SFK-275SE Smart Endurance Active Balancing Battery! Yes the lightest and most energy dense LFP battery on the market that also features  a 150 amp bms, support for 4s series (48v) connections, active balancing and balancing control, and an easy to use smart app that allows you to monitor a single or up to 4 batteries simultaneously!

The GEN 2B  switch gives users greater control over their battery as now the Bluetooth system can be turned on or off with a touch of the button giving increased security. Users are now able to fully manage the built-in active balancer as it can be set to run in normal mode, 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 passive BMS balancing to manage the cells. Finally we have added a button to view internal battery temperature via a button press (this is represented using different colors to indicate battery temperature).

Built with certified ESS (Energy Storage System) cells with complete manufacturer test reports and certified to UL1973 standards, you will love the reliability of ESS cells that will stay in balance, have a long service life, and also have the power to output up to 1800 watts of  power. ESS cells have  an increased   cycle life of 6000 cycles at 80% depth of discharge, or up to 8000 cycles at 50% depth of discharge compared to automotive grade cells.

The SFK-275SE 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-275SE battery may be used anywhere where 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.
