The RC12V battery controller is designed for monitoring the status of the 1÷4 battery pack based (the total capacity of 84Ah/12V (SLA) max. batteries), on the measurements of resistance, continuity of the battery circuit, voltage, and the charge level. It is also protected against reverse connection and short circuit in the charging circuit. In the case of failure, a LED light is activated, which is accompanied by switching of relay contacts and acoustic indication.
