Lithium Battery: LiFePo4 12V 125Ah, BT, HEAT, Pro III

ELECTRICAL SYSTEM SERIES – PART 1

Auxiliary power is key to enjoying your vehicle as the base for your outdoor adventures. By separating the two electronic systems or circuits and corresponding batteries – one being the one that starts and runs your vehicle – aka main battery, and the other one being the one powering all your lights, heat and other appliances at camp – aka auxiliary battery, you are set up for any overlanding adventure. In this series I will run you through how I’ve designed and set up my electrical system, and explain each component. Feel free to ask questions or share your feedback in the comments section below.

The core of my electrical setup is the battery. I chose a lithium battery of 125 ampere-hours (Ah) with built-in heating foil, which means that it can be quickly charged even in sub-zero temperatures. The battery also has bluetooth monitoring via smartphone and display. 125Ah has lasted plenty for my use. I have enough power for lights outside and inside, and an Alpicool CX30 compressor cooler that stays on continuously when I’m out and about.

My battery is the LiFePo4 12V 125Ah, BT, HEAT, Pro III.

Sparelys

Both the battery and all my Victron Energy products were bought from Sparelys.no which is one of Norway’s largest outlets for solar panels, batteries, lighting and more for overlanders and others.
