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

I actually bought this product for my dad it replaced the old one perfectly so would recommend

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

As advertised

Once fitted it worked a treat as it should.

Does exactly what it's supposed to

This is a very light, efficient split charger which I have have fitted to my 1979 VW campervan. My consultant mechanic (VW Restorations of Halifax - I can't praise him enough!) admonished me for not having fitted in line fuses on both sides, and for not having secured the lines to the body of the van - he's done those things for me! So far the unit has worked very well keeping both car and leisure batteries in good order.

Good product works well topping up my battery after my cheep one failed buy cheep buy twice as they say

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.

I bought this in June 2021 and it worked ok for 6 months however it did started draining power from the main battery and I could not start my landrover. Initially thought battery was old so bought new one but same problem. Once disconnected all worked ok again. Don't buy.
