Makita behind on batteries

Recommended Posts

Makita has had 20 cell tools since 2013 and yet people still want bigger batteries for Makita tools. Current 15 cell batteries for the most part only date back to 2016 with flexvolt then others shortly after. Does Makita really need larger cells yet? Is 20 cells of 18650 really farther behind than 15 or even 10 of the 21700?

I am very happy with the 5AH batteries, but hopefully there will be a promotion on these when they come out.

I spoke to makita USA the other day about this issue and they told be they were working on a new 9ah battery. They weren’t sure on the release date but it is coming they said.

Why would I or anyone use a 12.0 on a drill or impact?... Not a chance, use the correct battery on the proper tool for the proper application.

There’s a guy who’s missing the point. Sure, changing batteries too often is inconvenient but an impact driver with even a 3Ah battery just goes and goes and goes. I’m actually planning to get a pair of 3Ah batteries at some point for this specific reason, even while they are the exact same size as the 5Ah.

I'm all for matching the tool and battery for the task at hand.  Then again it wasn't that long ago that dewalt xrp 18v batteries were the gold standard in cordless and a 9.0 pack isn't much different in size.  Personally I'm glad those days are in the past and love the new smaller and lighter tools but it might not be quit as ridiculous to others as it seems to us.

My point was that people do use massive batteries on impacts.

Reddawg didn't think anyone would.

 

These are the same idiots who use impacts in panels and on trim work.

People do all sorts of dumb things or should I say things that don't make alot of common sense, but the majority by far that use these impacts for a living won't put a 12ah battery on an impact.
It's a moot point as far as I'm concerned.

I like the 5AH over the 4 because they are the same size. I no longer have any 3 Ah.

I have a 2Ah Dewalt slim pack I use on an impact for drywall screws. At most, I’ll send a couple hundred screws.

The slim pack worked good on the nail gun the other day when I had to send 70 2” ring shank nails on a Hardie siding repair job. Noticeably lighter.

This is why I like the new slim higher output packs, the 4.0 on my Bosch impact last forever but keeps the weight down, just ordered a couple 3.0 HO Milwaukee slims too

So looking at this again, specifically the number (32) and arrangement of cells. What would be the voltage and ah on this? The connection appears to be XGT, but the cell count doesn't seem to work with 40V? I might just be missing something?

It definitely won’t be XGT. XGT needs multiples of 10 cells and this is 32. 64V Max seems likely as Quazar suggests. 128V Max is also feasible for the number of cells.

Not sure I am doing the math right, but dimensions would be at least 144x65x64 mm or 168x70x84 mm depending on the size of cells.

Perhaps an OPE dedicated battery platform?

I don't understand why don't tool manufacturers use li-po pouch cells.

Cylindrical cells are just not the right kind of tech for power tools because of the low discharge currents. Plus they take up too much space.

But li-pos pouches can discharge hundreds of amps because of the huge surface area, and they last much longer, like 80% after 1000+ cycles. 

Cylindrical cells only last 250-300 cycles at 80%
