Bought an 18 volt impact driver for grain bin construction

Thanks for all of the suggestions last week about using a cordless impact driver for 5/16 grain bin bolts. Menards had a special on Hitachi 18 volt impact drivers. The tool, two lithium batteries, and charger for around $100. Better than anything I could find on ebay. Comes with a full factory lifetime warranty covering materials and workmanship (whatever that means). Easily has way more power than required to torque down the bolts. Seems to have about a much power as my corded impact wrench. Easy to use all day lifting it up and down. Was thinking about getting a 3/8 or 1/2 inch square drive, but this 1/4 inch hex drive will have more uses driving screws after the bin is built.

I'm been a fan of 1/4 inch and 1/2 half inch impacts for a long time.

I find my 1/4 impact will shear off the 3/8 and 1/2 inch adaptors, so be careful and don't push them too hard.

Lithium batteries are making the news, catching on fire. Some say they catch on fire when charging and the hover boards catch on fire when discharging.

You may want to google to see if there are any recalls on your batteries.

As for me, I've had some good luck with Li batteries, more bad luck, cells shorting out or becoming open. Not a lot of stored energy in battery even though they have a 4 amp hr rating.

However, you can't beat a well made Li battery. I think the fires are caused by construction errors.
 
I've had the 12 volt LI Hitachi set for nearly 7 years now. That small impact is all I need and it's lightweight and easy to handle.
 
I just got that set at Lowes a couple
weeks ago for $160, too bad I couldn't
waight for a deal at Menards. I was in
a pinch though.

By far best drill/drivers I've ever
had. In my opinion worth far more then
the list price but I won't complain.
