@ a lot of people
Hello all. Thanks for reading this. I need some urgent assistance, with the problem of securing multiple Victron 12.8V 300Ah Smart Lithium Batteries in a yacht. Let me ask my question first and then provide some background.
Is there any reason why these batteries can't be held down with pairs of straps each, or with clamps pulling down on the handles at both ends?
Background.
These batteries are 51kg each. I am involved in a spirited discussion with my boat builder on what is an acceptable method for stopping them from becoming missiles inside the boat. I am insisting that each battery must be restrained individually, with a method that is capable of being tightened over the passage of time. This could use long bolts with nuts and clamps that pull down on the handles, or it could use strong pairs of straps going over the top of each battery. Either way, each of these methods allows for tightening, should the restraint system develop any looseness over time.
At the present moment the delivered solution is that the batteries are sitting in free space in a strong metal box, next to each other but with space all around, and not individually restrained. After my first complaints an attempt has been made to add some spacers, to reduce how far the batteries might move inside the box. There is a plastic lid on the box held with one strap. Inside the box, quite close to the batteries, are the ends of some protruding bolts that hold the battery box together. Yikes! These could easily punch through the sides of the batteries when they move.
I will continue to steer the boat building team towards a system that holds the batteries down individually, firmly and with ventilation space all around. Your best thoughts on my question above in bold, along with suggestions or examples of good restraint systems, would be highly appreciated. Time is short, so early replies will score extra points! :-)
Thank you for your help.
