Project Overview: Lithium Battery

This is a smaller project in the grand scheme of the van build, but it’s an important step: install the battery.

There are two main kinds of batteries used in van builds; AGM and Lithium. AGM batteries are cheaper, heavier and can only be discharged to 50% of their capacity before causing damage to the cells. Lithium batteries are more expensive, lighter, last 3-5x longer and can be discharged to almost 100% of capacity. The biggest drawback of lithium compared to AGM is that lithium batteries don’t handle cold weather as well. Otherwise, the lithium batteries seem like the best option for me, so that’s what I went with. Besides, I won’t be spending much time in freezing temperatures anyways, I generally seek warm weather, especially in my van.

Choosing A Mounting Location

I chose to mount the battery in between the passenger side rear wheel well and the back of the van. This is where I plan to put all of the electrical components, so it makes sense to put the battery here too. The battery, and all of the electrical components, will fit into an enclosure that I’m calling “the power center”, which I’ll be building in the near future.

Building a Wooden Base

The battery will fit inside this

To mount and secure my lithium battery, I cut some 3/4″ square strips of wood to screw into the floor around the perimeter of the battery. I used spax construction screws for this. The wood prevents the base of the battery from moving.

Tying Down The Battery

Top view. Notice the two holes in the metal wall. The carabiner is clipped in here through these holes

Here’s a close up of the carabiner and how it attaches to the two holes I drilled

Even with the base, the battery is still top-heavy, and liable to tip over. It will work best in connection with a tie down system. I used adjustable rope hangers for this. Aligned with the center of the battery, I drilled two 1/4″ or so holes into a raised metal part of the wall behind the battery. On the opposite side of the battery, I drilled a pilot hole into the wood along the base of the battery, and screwed a screw eye into it. the adjustable rope hangers have carabiners on both sides. So, I attached a carabiner through the two holes in the metal wall behind the battery, ran the rope over the battery, and attached the carabiner to the screw eye. Then, I pulled up the tension in the rope and ratcheted it tightly. There’s a little tab on the side of the pulley/ratchet that is depressed to release the tension on the rope and remove he battery, when needed.

Like a glove.

That’s it, the battery is in. Soon, things will be connected to it!
