I/O Switch:
I/O Switch
The GEN 2 B switch allows you to turn Bluetooth on/off, set Active Balancer mode, and monitor battery temperature. Standby heating or low temp charging mode can be enabled or disabled from the app.
Use this option if you want to see the temperature of your battery but prefer selecting between standby heating and low temperature charging from the app.
Data Port:
Data Port
This RS485 (half duplex) connection will allow you to get BMS data from your battery. Required for Victron Communication.
Move the data port to a different location (may be needed if space is limited).

Description

Features
  • 4.1 (range is between 4.0 - 4.2 kWh on average) kiloWatt hours of reliable lithium power, replaces up to 6 lead acid / agm batteries (100ah) and is designed to be discharged to 100% of available capacity without harm to the battery.
  • Up to 2.4 kiloWatts of peak power, and 1500 watts of continuous power.
  • 200 amp discharge capable, 125 amp continuous rating (can run 125 amps form 100% to 0% without hitting thermal cut-off limit).
  • GEN 2 B Switch allows Bluetooth to be turned on/off, full active balancer control, and can show battery temperature.
  • Expected cycle life of 8000 cycles at 80% DOD, and up to 11000 cycles at 50% DOD, 12-15 year usage life.
  • Fully compatible with existing 12v infrastructure including standard 12v lead acid/agm battery chargers, trickle chargers and high voltage DC systems up to 48v (when linked in series with 4 batteries).
  • Built-in cell heaters to allow for low temperature charging, temperature to activate heaters can be set inside the app, users can also test heating via the app.
  • Triple Heating Modes! The only battery on the market that lets users select how the heating system works, select form automatic low temp charging heating, or use standby heating to keep the battery warm even when its idle, or you can disable heating altogether and use low temperature protection only.
  • User selectable Max/Min State of charge, you can set upper and lower state of charge limits on your battery, e.g. set a lower limit of 20%, once the battery reaches this limit discharging will become disabled. Alternatively you can set an upper limit to 80%, so now you can leave your rv/coach plugged in and your battery will not be stressed as it will stop charging at 80% there by extending it's life.
  • Data Port allows direct integration with Victron systems with the Venos OS compatible devices like the Cerbo GX (when using the SFK data cable), other systems like Votronics, Growatt, Lux Power and many more will become available when the SFK hub is released. 
  • Smart phone/device compatible with Bluetooth monitoring/configurable app. Available for IOS/Android.
  • Can be linked in series up to 48v (4 batteries in series) as well as up to 4 in parallel with a combined output of 5.0 kW continuous.
  • Automatic low/high temperature and low/high voltage cut-off to stop battery damage from occurring.
  • Automatic short circuit prevention as well as over charge and over discharge prevention.
Summary

The latest and greatest! Huge capacity and endurance, with over 315 Ah of capacity and 8000 rated cycles the 315EX is the succesor to both the legendary SFK-300HP and SFK-275EX batteries. Available in both EX and EX+ (coming soon), the 315EX battery is equiped with the GEN 2 B switch, RS-485 data port (optional), Victron Communication, and triple heating modes (low temp charging, standby heating or disabled) making it the NEW ultimate battery!

Recommended Uses

  • 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 protected from water intrusion)
  • Use in Golf Carts or other small electric vehicles that have amperage governors (care must be taken 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.
