With the plate secured, it is now time to start attaching the terminal cables to the BMS, this will
vary depending on which BMS you are using, for all Sun Fun Kits BMS, we provide the BMS to
you with appropriately sized crimped and ready-to-install wires that you easily attach to your kit.
Most BMS units will include one or more NTP probes, these can be mounted at the position of
your choice. For The SFK-200V2 BMS unit, you may place these on one of the cells and on a
mounting plate (to get internal case temperature).
Heated kits will include 2 additional terminals that will need to be installed, these will vary based
on the BMS and or thermal switch you are using. For most BMS units, you will attach the
positive to the main battery terminal post on the lid, followed by the negative terminal which is
connected to the output port of the BMS
NOTE: it is extremely important that you do not
hook up the thermal switch or silicone heater pads directly to the posts on your cells,
this will by pass your BMS which may cause your cells to drain below the critical 2.5
volts level.
Installing the kit lid and selecting lug mounting options:
With your cables prepped and mounted, it's now time to determine how you will want to mount
your cable lugs to your battery kit. The V3.5 kits include 2 options: Terminal Studs as well as
flanged top bolts. The terminal stud option provides flexibility in terms of parallel and series
