Dual Operation VSS Switch HD Optic - 12/24V - 500A

This Voltage Sensitive Switch (VSS) automatically senses connected battery bank voltage and provides optimal, efficient charging of the second bank.  The VSS allows for independent battery banks to be combined or isolated based on the presence of a charging source (such as an engine alternator or battery charger), while also offering remotely activated, high current, emergency parallel connection. 

Designed and constructed for longevity in the marine environment with tinned copper conductors, stainless steel nuts, and high temperature, fibre reinforced plastics.  The units are ignition protected, provide On/Off switching operation, and may be recessed or surface mounted. 

The remote emergency parallel function can be operated through a momentary button on the dash which will parallel the batteries for 10 minutes.  Once this 10 minutes has passed, if the voltage is high enough, the voltage sensitive switch will stay engaged.  If not, it will disengage.

Features:

  • Dual battery sensing
  • Manual override option
  • Dual 12/24 volt operation (both banks must be same voltage)
  • Low power consumption (<6mA)
  • Lowered cut in voltage (13.3/26.6V) suits low output alternators and high temperature environments

  • Volts - 12/24V
  • Rating - 500A

Heaven sent
Size: Jumbo (25-Inch), Color: Dark Grey
My back suddenly decided to show me who's the boss. This reading pillow has been a God send! It is substantial without being too hard, soft enough to be comfortable without being too soft, absolutely no lumps! The outside cover is removable to allow for machine washing and is so soft to the touch. There is a handle on the back that makes it easy to move. This has allowed me to be able to sit upright, much appreciated!

Huge, super soft, cozy pillow!
Size: Jumbo (25-Inch), Color: Sage
This pillow is awesome! As a plus size person who can't sleep laying flat, the size and support level is perfect. This pillow is huge! The quality is very high, the stitching is precise, and the sage green material is soft and cozy. Great value for the price! I highly recommend this reading pillow!

MUST BUY Item for Breastfeeding Moms
Size: Standard (18-Inch), Color: Dark Grey
MUST GET item for breastfeeding moms. It is a soft pillow with a removable washable cover. The material is like a suede, which can make it hot to lean on if you typically feel hot when breastfeeding or sleeping. It allows you to sit up straight while in bed with great support.

It's perfect support.
Size: Extra Back Support (21-Inch), Color: Dark Grey
The best way to describe the super comfy reading pillow is super comfy. I use it to sit up while watching something soothing to my mind on tv and due to its comfyness and softness, it's perfectly just right for my back. The funny thing is within a few minutes I'm knocked out sleep, which is a good thing. It's soft but firm lumbar area and arms feels oh so comfortable. It gives the best sleep quality and less toss and turning. I highly recommend.
