Sun Fun Kits present the fastest, easiest, “stock-i-est”, Polaris Ranger EV conversion on the market! If you are looking to replace your stock lead acid batteries with lithiums then this conversion is for you. The SFK Polaris Ranger EV kit does not require changing battery trays, drilling new holes, or having to replace the stock (Quiq) charging equipment, it is a fast straight forward conversion that will provide you with between 45 to 70 miles of range and can be done in about 2 - 3 hours.
The kit includes 4x SFK315EX batteries, the SFK battery equalizer, 2/0 gauge series connecting cables, and 8 extended length mounting bots. The kit uses the stock battery trays and secures using the stock battery retention bracket. After the conversion you will be 400 lbs lighter than stock and will have 60% more usable range than stock.
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 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), 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 14 kW (18 horsepower) peak and will easily reach the top speed of your vehicle (limited to 23mph as per federal regulations). You can drive up to 45 miles at full speed off a single charge (on paved terrain), with mixed speed driving you can expect between 55 - 65 miles.
