Tools needed:
-10mm wrench/socket
-Zip ties
-Cutters
-Phillipshead screwdriver
-Electric tape (optional)
-Threadlock, blue/red (optional)

Step 1: Mount Battery Base to Downtube

-Remove all downtube bolts (top side)
-Step over, use all 3 plastic 3D printed shims to support battery base, secure with supplied bolts (bolt heads are flatter than stock bolts)
-Step thru variant, use only 2 shims - as the step thru downtube support bar, need to move battery base up by 1 hole
-Secure the bolts with threadlock, nyloc is applied to these bolts, but extra service life to ensure they do not come loose, threadlock is recommended
-Power cable to be routed later in the later steps

Step 2: Remove Seat to access controller bay

-Remove seat to access controller bay for Rover Gen1-6 on the underside of the seat, with 10mm wrench/socket.
-Unplug the XT90 yellow connector

Step 3: Install Battery Balancer Inline to all XT90 connectors

-Install the battery balancer module inline to the XT90 plugs. It cannot be done incorrectly as the controller connects with 1 polarity and the other 2 plugs match any battery polarity connection. Plug either battery, start with main battery into battery balancer spare XT90 as it is close by.

Step 4: Cable Routing and Cable Management

-Route the 2nd battery power cable to the controller bay (route to the front side of where the other power cables insert to)
-Plug in the 2nd battery XT90 into the battery balancer remaining connector
-Tidy up any extra length of cable into the controller bay 
-Everything can fit inside, final look to tidy cable routing from 2nd battery to controller bay with zip ties needed
-Install the seat back onto the bike


Step 5: Slide on 2nd Battery to downtube

-Install battery and lock with key
-Both battery switches to be switched to ON


Final Notes:

-It is possible to only have 1 battery switched on to operate the system, but it defeats the purpose of the dual battery as the voltage drain reverts back to a single battery set up - so for best results operating with both batteries together gets the longest distance at the highest speed possible. Compared to running 1 battery out and then the other, you will get slower speed gradually twice.
-However it is sometimes a user preferece to remove the 2nd battery to make the bike weigh 5.5kg less, to leave the battery at home for the whenever that is needed.
