Tools Needed: 3mm hex key for the mounting screws and a pair of scissors to cut the zipties.
1) Once you unbox your new Ranger, plug it to the charger and charge until it is full (you will know it's full when the light on the charger is green). The Ranger will not arrive at 100% charge so it must be charged all the way before first use.
Due to standard practices for shipping batteries, and battery health, all batteries must leave our facility at nominal voltage which is around 47V (54.6V is full).
2) Remove your Stock battery and charge it to full.
Since this is a parallel battery mod, both batteries must have the same voltage when they are connected. You can match the voltage by charging them both to full. Connecting at different voltage levels causes an influx of current to the battery with less charge. That influx of current can damage both batteries. You can think of this like air-pressure on an airplane. When connected the batteries have to equalize, so you want them to be the same.
3) Attach the mount to the bike with the included screws. One screw is okay but it is recommended to use two. Attach the mount so the “bulky” part of the mount is facing down.
We recommend facing the mount this way so that the weight of the battery rests on the mount. In the other orientation the battery is held on just by the lock.
4) Figure out how you want to route your wire and start routing it along the frame or with other cables. Secure it along the way with the included zipties.
There are a couple different ways to route, we made the cable long enough so there is some flexibility with this.
5) Cut the ziptie under your seat that holds the plastic wire cover in place.
6) Detach the large connector that runs in that section and attach the splitter connector.
The reason we have you remove the Stock battery from the bike before this install is because if you accidentally touch the cables together in the wrong way while connecting, there is no power flowing through so there is no risk of spark/damage.
7) The extra slack can be pushed under the seat with the rest of the wires.
8) Resecure the plastic wire cover in place with a ziptie.
9) Reattach your Stock battery (just your Stock battery) to the bike and turn it on. If the display turns on, that means everything is working as intended. Turn your Stock battery off after this is confirmed.
Both batteries should be off when connecting to each other.
10) Once you confirm that both batteries are fully charged, you may now connect the The Ranger Battery Upgrade to the mount of your bike. Please ensure that the battery is locked and secure on the mount before beginning to ride.
