# 91102R - EXTERNAL VOLTAGE REGULATOR WITH REMOTE VOLTAGE CONTROL for B-Circuit. For Industrial, EMV, Limo, Marine, Police Car, RV, Taxi and moreI wouldn't mind getting one, any links to a good one?
This is the common one that I use and I see others use. My model Jeep only charges mid to high 13V on the factory regulator so I've been externally regulating for ages. 14.4-14.8V is optimum for charging "12V" car batteries.
