Blue Sea Systems 300 Amp m-Series Battery Switches

These are the switches we’ll be using to turn on or off the individual power inputs. When using a lithium ion power bank it’s important to isolate the batteries from any potential vampire loads. Lithium ion batteries are really good at holding a charge for a long time, but it’s important not to let them discharge below 10% State of Charge (SOC) to avoid damaging the battery. There are often small controllers and other small electronics that draw very small amounts of power that aren’t easy to detect. These switches will allow us to isolate our batteries when they are in storage mode.
