Using the SFK battery equalizer, you won’t have to worry about imbalanced batteries as the equalizer will ensure all batteries stay in unison. If you ever decide to sell your Ranger, you can use the 315EX batteries in a normal 12v based setup such as in an RV, boat, or back up power. The batteries support heating (both during charging as well as standby heating which can keep them warm even when not charging so you will not have regen issues when operating in below freezing conditions), bluetooth communication, and have a user friendly app that will show you vehicle speed, state of charge (fuel gauge), vehicle power and battery temperature. The SFK315EX also support battery life extending features such as setting a power reserve cut-off (e.g. you can set the batteries to stop discharging when only 10% is left) or you can send a maximum charge level (such as setting it to 90% max charge) this means you can leave you batteries plugged in and not worry about degradation at high or low states of charge levels. In terms of performance, you will have access to 18 kW (24 horsepower) peak for up to 50 seconds and will easily reach the top speed of your vehicle (limited to 25 mph as per federal regulations). You can drive up to 60 miles at full speed off a single charge (on paved terrain), with mixed speed driving you can expect between 60 - 75 miles. Features 16.4 kWh of reliable lithium power, replaces all 8 lead acid stock batteries and weighs 360 lbs less than the stock battery system with double the range. 60 miles of range of aggressive driving (90% power level) or up to 75 miles of range in leisure driving (60% power level). Up to 18 kW (24 horsepower) of peak power, and 7.5 kW of continuous power. 350 amp discharge capable, 145 amp continuous rating (can run 145 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 Hisun Sector E1 architecture including onboard Delta-Q IC 650 charger (can be updated to Lithium profile). 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 option for future expandability including wired options and add-on, required for future firmware updates. Smart phone/device compatible with Bluetooth monitoring/configurable app. Available for IOS/Android. 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. Recommended Uses Use in electric ATV units that operate in the 48v range such as the Hisun Sector E1 Use in other DC setups where a 48v dc supply is needed Can be re-configured to run in 24v (2s-2P) Can be re-configured to run as a large 12v power bank (4p) Downloads SFK315EX-Manual-Revision 1.6.
