The "RMPARBU/24-6" has been designed specifically to allow the operator to connect two HAWK batteries into an ASP sensor post, effectively doubling the time, whilst giving the operator ample time to change the empty battery without incurring any down time.

Unlike a "Y" lead, which parallels the two batteries together, and delivers power from the highest charged battery first, ending with both batteries being in a discharged state together; this unit automatically selects the lowest charged battery first and continues to use it until it is virtually discharged, whereupon it switches to the higher charged battery.

A series of LED's inform the operator which battery is in use and alerts him/her as to which battery requires changing.
