Battery testing is a crucial part of choosing the right battery for your tool. In this test, the experts at OPE Reviews use the 5 amp hour power stack to figure out what voltage sag is the most acceptable for balancing battery size and weight. They use an 8-inch pruning saw, but it proved to be a bad situation, so they switch to the 12-inch 20 volt top handle saw to test the batteries.
Watching the voltage and voltage sag helps to determine how many amps the tool will use, and how much power the battery can hold for the said tool. The team makes three cuts with the 1.7 amp hour power stack, and though it wasn’t enough, it gave an idea of what would happen over a longer period.
The test was carried out with different battery sizes from the 1.7 amp hour power stack to the Flex volt 9 amp hour. The 2 amp hour compact battery failed, while the three and four amp hour compact batteries fared better. The 5 amp hour XR battery came through, and we see more significant differences between the six and eight amp hour batteries.
The power stack 5.0 overperformed, and the experts were impressed. The battery even stayed cool after 30 cuts through Poplar despite the saw running hot. The test results show that the power stack battery is the way to go, though the size difference may be a problem for some. If you’re looking for a small saw with a lot of power to get things done, then the 12-inch saw is the way to go.
This test was impressive, and if this is the future of Battery Technology, the next five years will be a game-changer. The experts are thrilled to see what the future holds regarding battery technology.

Hi ! Interesting test to be honest. You Fluke needs a fresh new 9V battery 😀
Make sense when you have a wide spread surface for the cell to release energy than a cylinder help big time.
Great job ! Brian 👏
Hello again Tool Shop Addict
Thank you for another Great Video 👍 This was a very good test. As I am researching for my next tool purchase. And cordless tools are on the list. It's a hard call to decide, Milwaukee or Dewalt. I am looking for 12 volt tools. One because of the savings in weight and the smaller size gets into more places easier. Again thank you 😊e
The 1.7 AH powerstacks are awesome on Impacts. The 5AH powerstack should be the standard for everything else. The price needs to drop though, I'm not willing to spend that kind of money on any battery.
I'd like to see you test run time. Dewalt videos show it lasting far longer than the standard 5Ah battery. I don't trust any companies marketing so it would be nice to see some real tests on this.
Great content! I now have four batteries 1.7pscurrently. When do you think or know 🤔 the 5ps will be available in Canada 🇨🇦 Currently none!? Also do you like the B20 thermal imager or the next model up?
For my tool suggested try the grinders just bought a DCG416B flexvolt advantage didn't last long at all with 1.7ps thanks 🙏
Can you test the 10ah I feel like that’s the best runtime to size ratio.
And yet again, the 6Ah XR is clearly a way better value.
its kinda old now but i feel alot of people dont know or havent seen much about the craftsman v60 16inch brushless saw
Ive always wondered how the 10ah battery stacks up performance wise. You should add that in to testing
I can see SBD making after market replacement batteries for EVs in the next 20-30 years lol.
People will literally be grudge racing DeWalt vs Milwaukee in their hopped up evs.
I see you are doing plenty of videos with measuring voltage. One tip, if I may: by measuring every battery's own internal resistance, we could assign very specific meanings to every voltage drop with the tools. By knowing internal resistance AND the voltage drop in a specific use case, we can calculate the current provided by the battery in that situation, and from that the exact power input of the tool. This spares difficulties measuring the current.
Voltage drop by itself is good as a guideline, but not enough to compare results across different batteries.
To determine a battery's internal resistance, all we need is to connect a known load to the battery alone, like a car headlight bulb or smth, and measuring voltage and current. If we know the resistance of the bulb, we can calculate the internal battery resistance which then can be used in any situation with a tool.
Thank you for another very informative video!
You should make Workshop Addict coster sets with all those wood disk pieces you’ve been cutting! 🤔 money maker idea right there I tell you what.
I got a question. I'm new to saw tools. My question, when should you use a reciprocating saw vs this saw? Why use 1 over the other? I just brought a reciprocating saw but now just seeing this video and wondering if I should keep that saw or get this one.
WTH! You didn’t even test the 15aH Flex on the 12” saw…just kidding 😉
I’m very surprised that the saw didn’t stall with 2aH battery.
As you said interesting to see where Dewalt takes this battery tech. Hopefully Flexvolts soon.
Thanks for doing these tests as it helps me select the best battery for the tool/job at hand.
BTW in a previous comparison video you asked about testing procedures with all these batteries. My only thought is that my 5aH and 4aH XR packs are my oldest and well past the 3yr warranty period. As I recall lithium cells degrade over time (dependent on the charge cycles) and in my experience a bad cell can compromise an otherwise good battery pack despite showing it was fully charged (I had 2 12AH Flexvolts do this ouch!) If you are not already doing this, I would suggest that all the packs compared should be within the manufacture’s warranty period to ensure consistency.
I like my 1.7AH powerstack batteries, I got a good deal on two of those. Be nice if next year they came out with a 9AH Flexvolt Powerstack battery that was lighter and smaller than the current one.
PowerStack needs to come down in price. Impressed with 6 amp/hour battery
The 5.0ah powerstack it's beast and the future of cordless tools, but currently i think the 6.0ah is very good deal in performances and price.
Hello Workshop Addict
Second !! Great work Brian !!
