Essential Add-On For Any RV

Based on my observations the Samlex America BG 40 Battery Guard is a must-have for any RV owner. It ensures that your battery maintains a safe and healthy level of charge, which is especially important when you're off-grid. The sleek design makes it easy to install and the LED display is a helpful touch .The only downside is THAT it's a bit pricier than some other battery guards on the market..

Pros
  • Helps prolong battery life by preventing over-discharge.
Cons
  • Does not provide information on the current state of the battery.

My Samlex BG-40 Battery Guard only works occasionally.

I am using 200W 12V solar panels with a PWM charge controller. I programmed the BG-40 to position 9, ie disconnect at 12V and reconnect at 13V. Often it does not turn off at 12V. When it fails, my Samlex inverter (model PST-300-12) shuts down at around 10.5V and reconnects at 13V.

Pros
  • Easy to use
Cons
  • Some little things
