One battery. Two voltages. The FLEXVOLT battery is backwards compatible with DeWALT's 20V MAX tools so you get up to 4x the runtime.

Battery Charge Hold
I have a two of these battery packs and they do no hold their power charge for more than 5 to minutes of use full time before having to recharge them. These are very spendy power packs for what use you get out of them at a time.

Best battery so far
I love the new flex volt tools and esp batteries they last so much more time then the original.. my friends tease me telling me my box truck is a mobile dewalt showroom, but its full of dewalt becouse the quality of dewalt in my opinion and 30+years experience far surpasses all other name brands. Trust me ive tried all of them. Thank you dewalt for continuing to make my everyday work so much easier and less stressful by providing the best tools designed for the jobs i use them for..

Short battery lifespan
The others saying battery not taking charge is true, mine only charged less than 10 times, then die, I take apart the battery found some design problem with the balance board inside the battery, even all cells are good, but if some of the cells drop lower than like /3 volts, then the whole battery won’t take charge

Good in the beginning.
They are good in the beginning but will die and not hold a charge after 4 months. Now granted, I had major demolition going on and used it almost every day. Just not something I want to purchased every six months for a new battery.

Wont take a charge after 6 months
I bought two batteries 6 months ago. I loved them but they won't charge anymore. It's not the charger because my other batteries still take a charge. Store told me to send them back to dewalt but not sure how to go about doing that

Best battery you can buy
Charge lasts forever and that’s the reason I bought them. Main use is for my dewalt cordless tripod light.

Old a nice long charge.
These are great batteries that hold a nice long charge so you can work most of the day without having to grab another one from the charger. A little pricey but everything is anymore. So far worth it.
