Query: works well but i think i needed a bigger one

I bought for my 4 1/2 in angle grinder to do some work way out yonder. well this was way cheaper than a genny so why not I have a few good batts laying around as I am an auto tech. works well but I had to cut3 1 1/4 solid steel bars with the grinder. I had one battery and sometimes would overload and shut off.it got the job done but was a pain everytime it overload. I did the math on the grinder and should of worked. called the company and they said probably needed the next size up and or use 2 batts but hey it got the job done. you cant beat the price of $69 with free ship. still beats a genny plus a lot more quiet. I still use it for odd jobs where theres no power. but be warned as a auto tech use a stand alone batt or you may be stranded with a weak batt on your vehicle. it weakens a batt quick it draws a lot of juice. it also powers 60w house lamp no problem. all in all not to bad.
