bag tearing

I noticed that the cooler bag which houses and protects the two (heavy) gel-cell batteries is tearing at the handles. Each battery is 40 pounds.

It was the dolly cart that I thought would break under the weight. It's working fine.

When I lift the bag by the handles, it is tearing the bag.

I put two straps around the entire kit, under the dolly and around the bag. I will lift the power tank by this, going forward.

Hmmm, I could perhaps fabricate a custom strap with the old race car seat belts...
