I think the longer lifespan claim could be justified (within loose marketing terms) when referring to the whole pack; I have had a few older lithium packs which have gone dead because one of the cells was lower charge than the others, and eventually failed making the pack useless unless you know how to replace one cell, which most consumers don't.

[@AK90]

I bought the "wireless" glue gun from Lidl a while back. You put it in a dock to heat it up and when you use it it doesnt have an annoying cord dangling around. When you are done just put it back in the dock and it starts going up to temp again. Really handy and works like a charm. For power tools though we are all about Makita :P

[@jlucasound]

Those are really good looking tools as well as being useful.

[@ruinunes8251]

You should try over discharging it in order to see if the circuitry has any over discharge protection.

[@Peter_A1466]

With unprotected cells cell-balancing is quite important. Unbalanced, one of the cells can become reversely charged, or at least drag the whole pack down.

[@korishan]

With Li-Ion cells, if they go beyond their rating, cycle life can be drastically reduced. For instance, if you charge to 4.3V, that can literally pull 100's of possible cycles out of the cell if happens repeatedly. The same is true if a cell voltage drops too low. Most cells are designed for 2.5V for absolute bottom voltage. Going to 2.2V could reduce life span drastically, just as overcharging. The other issue with over charging is that it can cause the cell to go thermal, heat up until it catches fire. Altho, the bms has a temperature monitor (or at least it should) to stop charge/discharge once temps reach a certain threshold, usually around 120F/48C, or less. I have seen some as low as 45C. So if this bms in these units are "actually" doing as advertised, then yes, it can extend the life of the battery by several 100 cycles. As long as the balancing voltages are set correctly.

[@Thomas-tf4cm]

I think these tools and batteries are amazing for the price.

[@steveoddlers9696]

I bought a corded Parkside jigsaw recently, quite happy with it so far. Have to see how long it lasts.

[@danheason8569]

The secret with the 12v angle grinder is don't use it as a grinder, mod it into a die grinder, then it's awesome!

[@ibmezouar]

What do you mean?

[@ljchrzan]

I just took apart a 12 volt Parkside battery sold in the USA. The drill and battery appear to be almost identical, but the item numbers are different. The circuit board on the battery is completely different than the three shown here.

[@MostlyInteresting]

These look almost identical to the Rockwell's in the states. I think that line has faded out though. I rebuilt my 1600 mah batteries with 3ah batts. And yes those have connections in between the cells. But the balance circuits are in the charger.

[@PaulineWolfrum-ic6yy]

Can u charge a newer model battery with an older series charger? Both 12V but old batterie and charger only have 1,5 Ah, new battery has 2,5 Ah. New battery has that little, metal ID pin, old charger doesn't.

[@DIYwithBatteries]

Wow nice batteries ;) 👍

[@keithking1985]

i liked that video it was good. ten thumb's up..!!! : ) in fact they look better made than i was expecting : ). NICE ONE, !!

[@funkblack]

What does that circuit do? Will I be able to charge the battery pack with a third party charger matching the original output values without overcharging the cells?

[@rickybobby7660]

Would that handle being charged by a permanent magnet generator as in a motorcycle battery?

[@Soapy555]

When you say its a bit 'Noddy' are you referring to the guy who lived in Toy Town, or the bloke out of Slade?

[@JulianIlett]

Big Ears's mate :)

[@frankhovis]

@@JulianIlett That's no way to talk about Mr. Holder. Even if he does have big ears.

[@efdawahfan]

does a1 and a2 also cell balance ??

[@LOTPOR0402]

Would this charge up from a 12v solar setup ?

[@ElmerFuddGun]

Over size packaging but at least it was cardboard and not plastic!

[@MrScotttraynor]

or the new brand of batteries fail more often, so a safety feature?

[@ruinunes8251]

I noticed today in their website that their 20v batteries for sale also shows: "Cell balancing for longer life and an increased life span" So you may need another trip to LIDL, buy a 20V battery and make another review.

[@JulianIlett]

New 20V tools available from Sunday :)

[@ruinunes8251]

@@JulianIlett Yes, you are right, I missed that bit. I also noticed them showing a 20V cordless bench grinder. The thing is, when you read the description, it says 120watts. I need to wait till Sunday to see if it is cordless or not.

[@David_11111]

yay

[@tamask001]

How is the 12V 5Ah variant? Is it just a 4Ah with larger capacity cells?

[@8500gtNvidia]

Hey i just bought some power tools from lidl and a 4Ah battery...has that small central pin also. The question is: can i charge the battery just connecting plus and minus on a 13/14v 2.5A power suppy? Is there any pint to be short out in order to enable the mosfets to take power? (I have a bench power supply so i can be confident using it).

[@krzcho]

I need it as well; have you successfully charged it externally? What voltage/current?

[@TheEmbeddedHobbyist]

Come on Julian Aldl are feeling a bit left out. ;-)

[@JulianIlett]

I've got a couple of Aldi treats coming up :)

[@technologicalsingularity1788]

Even weird 1st gen battery pack has no balancing function with all that complex pcb. Maybe "balancing" means active balancing?

[@anth_7159]

will a charger for an a1 battery charge an a2/a3 battery? i can find loads on drills/battery's etc but nothing much to do with chargers except stripdowns.

[@mattylad8035]

I think so yes, I use the same charger for my A1/A2 batteries. Although I removed the polarization splines on the A2 so it fits the A1 so I have to be careful of the rotation I put it in.

[@haxemeback9304]

Not sure what is it

[@stakkerhmnd]

Is "cell balancing" to make sure they are all of exact equal weight? If one cell is a bit below weight a small strip of lead is added?

[@KNfLrPn]

Correct. This is done so that if you hold the wrong end of the drill, there is minimal vibration when spinning. They don't use lead anymore though because of ROHS.

[@stakkerhmnd]

@@KNfLrPn Yes. I'd agree. Out of balance centrifugal forces caused by an out of balance cell. Maybe they use a vegan alternative to lead now? Due to ROHS.

[@KNfLrPn]

@@stakkerhmnd Lead is vegan.

[@stakkerhmnd]

@@KNfLrPn Yes. it's on the periodic table so it's all natural.

Hmm maybe I should get down to lidl but I am a waitrose kinda bloke:-)

[@CollinBaillie]

Disapppinted. You left the foam out. 🤣

[@JulianIlett]

Then I put it back in :)

[@markclark787]

I have always been unbalanced.

[@johntuck2152]

Bit disappointing that the newer A3 12 volt battery does not fit with the slightly older A2 battery tools. Marketing ploy !

[@ambydaly5713]

These batteries have reverse polarity to old ones fitted to older rotary tool!,,,,,,,,,,,,,,

[@ElmerFuddGun]

The black foam was backwards and caught half over the screw post because of *poor workmanship* not because of any resistor. - 3:09

[@jimsouthall1085]

And you wonder why there is a chip shortage?

[@priestland1]

My thoughts exactly

[@christiano.4808]

Yeah, the benefits of cell balancing on power tool batteries are basically not existant. It's ok to have, it won't do any harm, but it will not suddenly increase the life span of the battery very much. The effect of the balancing circuit will be greater towards the end of the life cycle of the cells when the cells will naturally start to drift apart, but until then it will basically do nothing as these cells will stay in balance on their own. And when the time has come then you'll rather replace the battery anyway because by then it will have reduced runtime and maybe also reduced power. The balancing will keep it usable for additional cycles but will obviously not give back the lost runtime and power.

[@setecastronomy_hc]

Cells are getting charged and discharged at high rates so even small differences in internal resistance will make a huge different after a while. Charging them at high rate requires a lot more monitoring, I've personally had some problems with that after a hundred cycles or so, however I've never used balancer with low charge rates. Parksides 20V batteries have bad LVP (if any) and I've had few of them go too low for charger, it just simply won't charge them. I use Imax B6 to raise up voltage a bit and then charge it with provided charger. It probably won't prolong lifespan by a large margin, proper low voltage and overcurrent protection are enough.

[@andymouse]

Fascinating, those drills might sell more if they didn't look like something out of Starwars, the moulding seems a bit OTT to me but I hate DIY so never mind.....cheers.
