12V 140amp Durite 0-727-33 voltage sensitive/intelligent Split Charge Relay

Fitted this to our VW Transporter T5 in 2018. It is connected to the leisure battery in the rear of the vehicle which is a 110AH.This is then connected to a 200w inverter which provides the 240V power to the rear of the van. It keeps the leisure battery topped up just fine and switches off the charging when the leisure battery is full or if the main starter battery voltage has dropped below the 12.65V threshold. A red light on the front of the unit illuminates when it is charging the second battery. Make sure you order a few water proof in line fuses with it to ensure nothing bad happens if the unit fails. You can contact Durite directly to find out what you will require, they are very helpful. This is the telephone number I used: +44 (0) 1255 55520

Excellent

Little bit expensive, but you get what you pay for good quality

As advertised

Existing Durite split charger had failed. Easy to fit as direct replacement. Does the job and leisure battery now charging again. Arrived on first day of the expected delivery window. Vendor also supplies complete fitting kits if you need this to add split charging to a vehicle.

East to install and works well....and I am a complete amature!Simple to wire in between batteries with no messing about.

It worked but the neutral/ ground wire is thin and fragile. The unit stopped charging the leisure battery after 6 months. Buy cheap, buy twice.

Once fitted it worked a treat as it should.
