Battery-temperature feedback for compatible controllers
Let supported Renogy controllers adjust lead-acid charging for temperature.
The Renogy RTSCC Battery Temperature Sensor uses a stainless probe and 3 m cable to report battery temperature to selected Renogy solar charge controllers. Compatible controllers can compensate charging voltage for changing lead-acid battery temperature.

Do not use RTSCC with lithium batteries Renogy states this temperature sensor is not compatible with lithium batteries. Lithium charge-temperature protection should follow the battery BMS and equipment instructions.
Why this Renogy product
More appropriate lead-acid charging across temperature changes
Temperature compensationA compatible controller can adjust its lead-acid charge voltage from the battery's measured temperature.
Long probe leadThe 118 in cable reaches from a nearby controller to the battery installation.
Durable sensor tipThe stainless probe is designed to contact the battery case for representative temperature measurement.
System fit
Use only with controllers that document the RTSCC two-pin sensor.
Selected Adventurer, Rover and Wanderer models support RTSCC, but ports and accessories vary by generation. Place the probe against the battery case as directed and route the lead away from damage.
Lead-acid onlyUse with a supported sealed, gel or flooded charging profile; do not connect it for lithium charging.
Probe placementSecure the sensor where it represents battery temperature and is not heated by another component or direct sun.

Common questions
Buyer FAQ
Can I use it on a LiFePO4 battery?
No. Renogy states that RTSCC is not compatible with lithium batteries.
Does it fit every Renogy controller?
No. Confirm the exact controller model, generation and two-pin sensor port before ordering.
Where does the probe go?
Attach it to the battery case in the location and manner shown by the controller manual, away from external heat sources.
Does it replace a battery monitor?
No. It supplies temperature feedback for charging; it does not measure state of charge or energy use.
