With version 3.5 we have color coded the BMS wires to match the active balancer to assist in
installs, you can use this combination to ensure you have matching connections.
Your voltages should read:
3.3, 6.6, 9.9,13.2 (Nominal Voltage).
If you are using a supplementary balance, you should install this as well, you will need to share
the final negative and positive terminals of the battery for the bms and the supplementary
balancer..
Make sure the wired main lugs are the ones that touch the cell terminal
and only
stack the other bms and active balancer rings on top.
