VEVORSplit Charge Relay Kit, 6mtr 12V, Automatic Dual Battery Isolator Kit with 140AMP Voltage Sense Relay VSR, Compatible with RV Marine Car Vehicle Truck Caravan Camper Yacht ATV UTV Boats Workshop

seems very well made with very good cables, a bargain my 20 year old usa made battrey splitter was going to cost twice as much to replace with no cables or clamps included and that brand is also china made now anyway!

I installed this device in an1971 VW bus. This product was very easy to install! Worked first time which is a rarity for me!Everything you need for the job was included.

Easy to install, works great, well built, complete kit. Now I don't have to worry about shore charging second battery.

If you have some 12 Volt knowledge it is a very good product as of now….I just installed a secondary battery for my truck so we will see in a few months after I have put it through some real world tests and see how it will hold up….I don’t understand as to why we have to rate some of the products we buy here on Amazon when we just get the product in or sometimes we haven’t even received the package in and they are wanting a rating before we get it…Doesn’t make sense….

Perfect! Easy install for second battery in bed of Toyota Tacoma. Worked great.

Installed for a few months now and 0 issues.

Automatically switches to charge the lower battery or batteries, keeping the truck start battery as the top priority. Works very well for my work truck to have a set of batteries running an inverter all day. Very happy!

Great value and works great to isolate diesel heater battery from cranking battery in van, well worth the money, cables alone cost more!
