Jump Starter 'battery' pack

[Machinebuilder]

I had a small one I kept on my DR350. It worked well until I noticed it had swelled and broke the case.

I don’t remember the brand but it was a cheap one. I still need to replace it. I priced the Snapon one at $250 and it has the warranty

I 'bit the bullet' and ordered a Micro Start xp10. Hope it works, opps, hope I never need it......
