07Sierra Posted August 8, 2018 Report Share Posted August 8, 2018 I know the 5ah could supply more runtime but with the new high end 21700 cells in the 3ah compact, do you think it could supply the same type of performance in the bigger tools like the impacts? Could it supply more amps compared to the the 5ah? Quote Link to comment Share on other sites More sharing options...
TrimmerMatt Posted August 9, 2018 Report Share Posted August 9, 2018 5ah should still outperform the 3. There are 2x the cells so they will see half the load. 21700 cells are better but not twice as good as 25r in the 5.0. Quote Link to comment Share on other sites More sharing options...
07Sierra Posted August 9, 2018 Author Report Share Posted August 9, 2018 Wonder how much better they are then the 2ah... Trying to decide between 1 3ah or getting 2 2ah Quote Link to comment Share on other sites More sharing options...
Cr8ondt Posted August 9, 2018 Report Share Posted August 9, 2018 I have multiple 2, 4 and 6ah, there is a significant noticeable difference when using the the 4/6 batteries in all my tools. I believe the discharge rate of the 3 is better than the 2 but not quite the 4 or 6. So based on that I'd go for the 5 vs the 3 all day long. the 3 is obviously a run time boost over the 2 but if my only choice were 2 2's or 1 3 I'ed take the 2's, charging 1 while using the other vs waiting for the 1 battery to charge.

Babysaw Posted August 9, 2018 Report Share Posted August 9, 2018 If the service center deal if still live, that is your best battery deal. Turn in two ancient worthless batteries from a thrift etc for two 9/3 flexvolt, $199 1 Quote Link to comment Share on other sites More sharing options...
Jpgwoodworking Posted August 10, 2018 Report Share Posted August 10, 2018 I’m not impressed with the 5ah batteries honestly. I have a bunch of 2 ah’s for drills, impacts, and small tools, and a bunch of the 6ah Flexvolts for saws, fan, vacuum, blower, etc. The Flexvolts are a significant increase in both power and run time for everything I use them in, but they are too heavy and bulky for the 6 1/2” trim saw and compact brushless recip. I use the 5 ah batteries in those tools, but it’s not uncommon to use 3 batteries in a day working by myself. The 2 ah’s and Flexvolts last close to a week in the tools I use them in. The 3 ah would be nice for the OMT, as it’s a battery hog but best kept light and compact. Quote Link to comment Share on other sites More sharing options...
Framer joe Posted August 13, 2018 Report Share Posted August 13, 2018 Imo....the 5ah is the perfect battery in all 20v tools except nailers....I have dozens of all the batteries but 12ah....the 5ah are cheap on eBay also... 1 Quote Link to comment Share on other sites More sharing options...
Mordekyle Posted August 13, 2018 Report Share Posted August 13, 2018 2AH in finishing guns, They will run for days. 5 AH in Most other 20 V tools. FV on the 20v saw. High increase in performance is worth way more than the small increase in weight. Sent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
The.Handyman Posted August 13, 2018 Report Share Posted August 13, 2018 I love the new compact 21700 cell 3.0ah batteries in the nailers as it offers a wider more stable base to set the nailers on.

Babysaw Posted August 14, 2018 Report Share Posted August 14, 2018 The planer also runs noticeably stronger with flexvolt batteries. I rarely need more power than a 4ah can offer but it’s nice when you’re planing something super hard to have that extra oomph. if I’ve got a grinding wheel on my drill, doing some rust cleanup etc a flexvolt battery is also nice. I’ve only got 6/2ah flex batteries, do the 9/3ah give more power, especially in the 575 saw? Quote Link to comment Share on other sites More sharing options...
Mattias Blomqvist Posted August 14, 2018 Report Share Posted August 14, 2018 Today was the first time I put a 9.0ah FV battery in my DCS367 recip saw and man what a difference in speed that boy got compared to a 5.0ah.Skickat från min SGP511 via Tapatalk Quote Link to comment Share on other sites More sharing options...
Framer joe Posted August 16, 2018 Report Share Posted August 16, 2018 @Babysaw...I would only use 9ah or 12ah in the 575 and 577...huge difference in performance and runtime 1 Quote Link to comment Share on other sites More sharing options...
Jronman Posted October 2, 2019 Report Share Posted October 2, 2019 I used a Flex in my OMT. Thats probably why it broke. Too much power. Using a 2/6 from full to empty in one session on the OMT creates a ton of heat. Quote Link to comment Share on other sites More sharing options...

Using a 2/6 from full to empty in one session on the OMT creates a ton of heat. I’ve wondered at this proving to be a potential issue for some tools going forward. As they were almost certainly all developed and tested using what we presently think of as “standard” batteries that aren’t outputting as much current as these larger capacity batteries can, along with the higher work output they’ll now get is more heat production and accelerated wear. I’m interested in seeing how that plays out over time. Quote Link to comment Share on other sites More sharing options...
xrh07 Posted October 3, 2019 Report Share Posted October 3, 2019 The 3.0 uses a Samsung 30T 35A cell. 5s1p = 35A max output. The 5.0s use a Sanyo cell capable of ~20A. 5s2p = ~40A max output. Quote Link to comment Share on other sites More sharing options...
