CHARGES TWO BATTERY BANKS:

This simple device allows the charging of two separate battery banks from a single charging source such as vehicle alternator with no risk of flattening your battery bank.


SAFE MAIN / SECONARY BANK MANAGEMENT:

By sensing the main battery voltage, the VSR (voltage sensitive relay) will only connect the secondary bank to the source when the first bank is fully charged and is 13.7V or over and will cut out if the main bank falls below 12.8V. This ensures thats secondary bank can never drain the main bank.

DUAL SENSE VSR:

Dual sense allows the unit to sense the voltage of both batteries that it is connected between. If either battery is receiving a charge the VSR will activate. This allows the charging of the second battery from an external battery charger or second charging source.


SUITABLE FOR SPLIT CHARGING:

The VSR can handle charging currents up to 140A with zero voltage drop, no moving parts and encapsulated design makes it suitable for marine applications as well as split charging systems in vehicles.

Very cool light without the long whips
Yes, it was tough to change to whipless but it also meant I could benefit from the lighting without huge whips behind me. It’s a personal choice but these worked out great. Highly visible and bright and the install was pretty straightforward and simple. You get everything you need with the kit. They look good and seem to be holding up durability wise very well. Overall, I may not stay with them over time but it won’t be because of quality or function. It’ll be because I want to see the long whips again behind me.

Perfect fit for a Tacoma.
There are 2 headlight bulb retaining clips in this packet that fit my 2013 Tacoma. Fits perfect, no modifications needed to the clips. Toyota dealers do not sell these clips alone, they must be ordered with the headlight housing. eBay has one for $50!!! AMZN beats them all.
