jay1028 Posted May 18, 2017 Report Share Posted May 18, 2017 I recently purchased a Ryobi weed eater and a Dewalt leaf bower. Both run on Lithium ion packs. The Dewalt pack (20v/ 5ah) gets pretty warm, warmer than I would like, when charging in the supplied DCB115 charger, Probably due to its fast charge capability. After doing some research, I have noticed that when a pack fails, it is always due to one or two bad cells in the pack. I am wondering if these chargers use cell balancing when charging. It is leading me to beleive that these chargers are just charging and not minitoring or balancing each cell so that they all get the same charge. Does anyone have any input on how these chargers operate and your experiences? Thanks Quote Link to comment Share on other sites More sharing options...
Craigh9916 Posted May 18, 2017 Report Share Posted May 18, 2017 The dewalt battery packs are sealed and don't let the heat out as good as other brands like the Bosch coolpack batteries but you've nothing to worry about as the charger you mentioned isn't a fast charger it's only 4 amp which is not fast like the Bosch 8 amp or makita 9 amp chargers ! This is due to the sealed packs they can't be charged as fast as they don't vent the heat , don't worry about it they will be fine Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Framer joe Posted May 18, 2017 Report Share Posted May 18, 2017 The 115 and 101 are faster charging then the 112..,but the flex fan cooled charger can and will charge a 5ah in half the time and be cooler 2 Quote Link to comment Share on other sites More sharing options...
Bremon Posted May 18, 2017 Report Share Posted May 18, 2017 @Framer joe is right, the 118 really is awesome. I was very disappointed the OPE comes with a 115. Quote Link to comment Share on other sites More sharing options...

DeWalt batteries (20v and 12v) are "dumb" batteries only having a temp sensor built in, relying on the tools and chargers. The Ryobi batteries have the charge controllers built in. Cost to manufacture is in DeWalt's favor doing it this way(and they enjoy NOT passing the savings on to us). Quote Link to comment Share on other sites More sharing options...

Bremon Posted May 19, 2017 Report Share Posted May 19, 2017 Only packs I've been able to overheat are Milwaukee. No teal or yellow. @Cr8ondt Dewalt batteries are noticeably more affordable here than red or teal, so I would argue they do pass along some savings. 1 Quote Link to comment Share on other sites More sharing options...
Framer joe Posted May 19, 2017 Report Share Posted May 19, 2017 @The.Handyman...naw never had a Dewalt pact overheat or get hot...warm ya...hot no....really never had a problem with a slide pack ever...I don't remember when they came out but mine all still work fine...

JimboS1ice Posted May 19, 2017 Report Share Posted May 19, 2017 The only tool I've ever heard them over heat on is the brushed grinder, but it was so rare to over heat because it usually ate a pack before it had a chance to over heat Quote Link to comment Share on other sites More sharing options...
jay1028 Posted May 19, 2017 Author Report Share Posted May 19, 2017 Just not use to a high capacity pack. It got warmer than I was confortable with but not hot that it couldn't be held. More like 35c. When I charge li-ion packs with an RC charger, you can charge at 1/2c and they never even get warm and they get charged to 4.2v. per cell and are all balanced.

I was implying comparing DeWalt to Ryobi battery pricing, take a street price(us) 2 pack of 4ah each, Yellow $130, Lime Green $100, yellow batteries are little more than a plastic box with 10 cells in em while lime green are 10 cells and a balance charge controller, so my point, lower cost to manufacture + higher retail = larger profit margin. I'm not exactly hating on DeWalt, I'm just pointing out a fact..... And before we get all High end vs low end I'm only talking about the batteries, TTI and SBD volume buy their cells from the same (or VERY similar) OEM's(IE Samsung, LG, Panasonic) and pay those OEM's the same per cell price.

Framer joe Posted May 19, 2017 Report Share Posted May 19, 2017 No one can beat that Ryobi 2 pact deal....sometimes it's 69$ after a holiday....seems like Ryobi doesn't make money on the battery just the tool ,which is inexpensive.....other companies make money on the battery and will give you a tool,free....

Bremon Posted May 19, 2017 Report Share Posted May 19, 2017 FlexVolt OPE comes with the crappy 115 charger, not the fan-cooled 118 (yes, really). Quote Link to comment Share on other sites More sharing options...

I wasn't making it up.... Pop open a Ridgid battery and you'll see almost the exact same thing, chip for chip part number for part number identical, just laid out different due to form factor.

Tug Posted May 20, 2017 Report Share Posted May 20, 2017 I find the Ryobi tools a bit hit and miss, but their cells seem pretty good. Quote Link to comment Share on other sites More sharing options...

I absolutely agree, my primary cordless stuff is DeWalt, but have a bunch of Ryobi odds and ends to supplement my "lesser" tool needs, example, DeWalt's caulk gun is $200 I have a hard time justifying that because I don't run caulk every day, while Ryobi is only $40, so that was a no brainier for me. 1 Quote Link to comment Share on other sites More sharing options...

Almost exactly what I'm doing! My entire inventory was stolen last year, so now I carry cheap tools that I don't worry about being stolen, but all my big guns are red and yellow. These don't leave my sight, they only leave my home if I know I'm definitely gonna need them. 1 Quote Link to comment Share on other sites More sharing options...

Framing is building the skeleton of the home or more broadly new construction: @Framer joe is probably asking because (we assume)most of the building space is used in the UK. 3 Quote Link to comment Share on other sites More sharing options...
Framer joe Posted June 3, 2017 Report Share Posted June 3, 2017 Yup yup.....as a framer we build the frame,install windows,doors,exterior trim,roof,siding and interior walls....we call it.."weather tight" ...plaster ready... Quote Link to comment Share on other sites More sharing options...
Tug Posted June 3, 2017 Report Share Posted June 3, 2017 No, we like our homes wind proof. Ha ha, I'm kidding, still mostly brick built, but with methods being tweaked year on year. I can't stand new-builds, bloody awful things! Chipboard floors upstairs, concrete floors downstairs, pre-fabricated loft spaces etc. This all adds up to buildings that're very awkward to rewire. The best homes in the UK were built by the Victorians, fantastic engineers! Nowadays? All crap! Quote Link to comment Share on other sites More sharing options...
Framer joe Posted June 3, 2017 Report Share Posted June 3, 2017 All crap in U.K. ? Not here....problem is in the USA,different codes by state.. if all building codes adapted cape cod standard there would be no house blown over ever .....ever here of a house on cape being blown apart ? No,..toughest codes in the US.....Arizona watches houses blow around ,Florida same thing ......quality lasts like Italian architecture or Greek....or cape cod...lol but true 2 Quote Link to comment Share on other sites More sharing options...
