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.

A gentle miracle for my skin!
I've been using this product for about a month now, and I'm honestly so impressed. I have acne-prone and sensitive skin, and this Ordinary product for oily skin has made a significant difference. From the very first week, I noticed my skin was softer. It’s lightweight, absorbs quickly, and doesn’t feel greasy at all. I use the Squalane cleaner both in the morning and evening. In the evening, I use natural moisturizer and B5 after washing my face. What I love most is that it’s affordable but delivers real results. No fragrance, no irritation—just effective skincare. I’ve already recommended it to my friends and will definitely repurchase.
