Another 1/4 ton pallet of batteries arrived at the house. The correct 8A4D size this time and the wrong larger 8A8D batteries have been picked up and returned to the manufacturer for a credit. Now it's time to move on to another milestone in the electrification of BIANKA. Installing the batteries. The batteries on an electrically propelled boat are the fuel tank that hold the fuel (electric potential) that powers the motor. It's pretty important function. So it makes sense that this part of the system and it's installation be thought out pretty carefully. I've already decided on the battery layout as shown in GOING ELECTRIC PART 15. Now it's time to install the real ones.

I tried to think about not just installing the batteries now but, also future installations and maintenance of the system. Such as being on a cruise and needing to replace the batteries. I am hoping to get at least five to ten years out of the batteries. Their life is yet to be determined. I am hoping new battery technologies will also be tested and proven in the future. Which is also something that an electrically propelled boat can take advantage of. But that is the future. The problem now is how I can install and maneuver the four 130 pound batteries into the hold. It's a lot of weight to be lifting and dropping into the hold and each can cause a lot of damaged to a person or boat if it drops. I then discovered this handy little piece of technology The Forespar Nova Lift:

This solved my battery installation problem. It has a capacity of 220 lbs plenty of safety margin for loading the 130 pound batteries. It could also be used to lift other items like an outboard motor or even a person who needs to be rescued from the water. I was so excited about installing the batteries I forgot to take photo of the actual above deck process using the Nova Lift. But, these photo "simulations" will give you a good idea of what the process looked like using the Nova Lift:

I laid a small 12 inch wide plank below the hatch so I could slide the battery onto the battery platform. This was very helpful.
I also came across something at a surplus electronics website that proved to be useful:
A pair of industrial rollers. They were just the thing to help maneuver the hefty AGM butteries once they were in the confined space below deck. Below is a photo of the first battery installed and the second one is on the plank on the way in.

Notice the small crowbar this was helpful in lifting and positioning the batteries into the correct location. The white grate items on the battery platform are a product called DRI DEK. It is made for decks and floors but, I am using pieces of it here for underneath the batteries. It serves three purposes: 1) It raises the batteries over the heads of the lag bolts securing the battery platform. 2) It provides an airspace helping to keep the batteries cooler and dry. 3) It helps keep the batteries from sliding on the platform. Also note the battery tie down straps for the same purpose.
With the battery installation completed the heavy work is done and I'm moving rapidly toward completion of the electrification of the BIANKA.
