Note:
1. If you are using a lithium battery, you do not need to install this temperature probe, the probe of the
temperature cable should be attached to the surrounding environment of the lead-acid battery, and the length
of this cable is 1.5m, so pay attention to the distance of battery and SPH.
2. If the cable such as “NTC” (lead-acid battery temperature sensor) cable is not used, please do not remove
the filler plug from the cable support sleeve.
