Making My Jump Starter Battery Even Better.

I love my little lifepo4 jump starter battery. I wanted to add an extra xt150 connector for use with my new smart jumper cable. Here is how I did this upgrade mod.

An xt150 male, led battery meter and a normally open micro switch.

I used my 100watt soldering iron to attach the connector to the battery terminals.

I wired the meter and switch in series then glued them onto battery. Pressing the micro switch will turn on the led battery meter.

Copious volumes of liquid tape on the terminals to prevent future electrical faults.

Here is my improved portable jump starter. With the smart jumper plugged in, the green led blinks. If I short the clamps, the red led blinks and it beeps! No electrical fault and damage to the battery for accidentally connecting it wrong.
