Reinforcing: Leather case to carry a motorcycle battery

[Littlef]

Working on an odd project.  I'm gonna make a leather case to carry a motorcycle battery, with a shoulder strap.  I'm picturing the aesthetic of a civil war era cartridge box.  I'm planning on using 9-10oz leather.  Its a fair amount of weight.  Do you think I need to reinforce it with a strap going underneath?  I'm a little concerned about stressing the seams over time, if its not reinforced.

How heavy is the battery ? around 1 -1.5 kg?  I'd be going with my gut and reinforce it.  But yes, it will be heavy on your shoulder, you may even wish to  make a shoulder pad of some sort . And, batteries having acid in them, I'd be putting plenty of sealer or waxes  or both on the threads.

Its about 7.5lbs which is 3.4 Kg.  I was planning on sealing the leather good, and also putting some sort of plastic bag/liner around the battery for a little extra protection.  I always wax my thread, but putting a little extra on the interior seams wouldn't be a bad idea either.  I'll work the design using some reinforcing straps.  The shoulder pad isn't a bad Idea either, although I'm not really planning on toting it around any great distance.  I appreciate the suggestions.  thanks.

The OP can tell us, but nearly all modern motorcycle batteries are totally sealed for life. Thus they don't spill acid when a motorcycle goes topside

I would put two straps around the case in a + shape with the ends of one making your carrying strap

I used to have a case of this sort for carrying extremely heavy dry cell batteries and a very large condenser for a portable camera flash unit. The gubbins for inside weighed about 6 lbs. The case was about 8 inches by 4 inches and 6 inches tall. Very thick leather, 3 straps around the body and a separate carrying strap held on by loops and D rings on the back

yea, its a modern sealed battery.   - That sounds like the right direction.  I'll work it up with 2 bands going around it, and the carry strap looping under and going through the two perpendicular bands.  Glad I didn't try to make it without the extra support.   - Thanks for the suggestions

i have an old leather bullet pouch it was made  by using one piece for the front back and bottom with the sides sewn in. That would be plenty strong to hold a battery in 10 oz. as the weak point is the seam which wouldn't have pressure on it being a side panel and not the bottom panel.

Thanks chuck, that's basically how I was going to approach the construction.  One long rectangle to loop around the battery, and then sew the sides in place. appreciate it.

Pictures speak volumes, what is the battery really for, does it weigh about 7 pounds??? I'd also add a couple of 1/4 inch screw post as insurance on each of the four sides (8 screw post total). An ounce of prevention is a pound of cure, plus it will look better.

standard sized motorcycle battery.  Its about 7.5 lbs.    That's a good idea.  Adding a couple rivets or screw posts would probably make it bullet proof.  Cool, thanks!
