Ozito Power X Change tools and Batteries, My Experience with and Living off-grid (not an attack against Ozito)

Hi all.

Moved to Far North Queensland, travelled in my camper to a new job where I live onsite in the camper. Had to rationalise what to bring, either the set of Ozito, a box set with a 1.5ah and 4ah battery, 2 more 3ah batteries bought as a deal at Bunnings cheap, the box set had a torch, circular saw, 13mm chuck drill, Impact Drill and 115mm Angle Grinder (faulty out of the box but did not use it for some time).

Out of box the drill was faulty, pull trigger drill starts and immediately stops though the trigger is still depressed, took it back, standing at the counter pressing the trigger having the thing do it's faulty cut out thing. I stop as it's probably an annoying thing for others, the guy who was called to serve me comes, the thing starts to work normal the instant he arrives, he says "Can't exchange it unless I see it". Me thinking "Like I'm gunna waste petrol to exchange a brand new tool for something identical just to be a dick" finally he walks away and is out of sight, me standing there dumbfounded pulling the idiot trigger, it starts the faulty thing again, luckily the guy could hear it and came back and exchanged it.

Purchased this set to work on my Slide-on Camper as I had a mix of older Bosch and AEG tools and only drills, the Ozito stuff, I thought, would make life easy and only one battery type to charge, finished the camper and sold of the other power tools.

Moved up here and stumbled into a 12 metre Volvo bus converted to motor home for $3k, older couple needed it off the site as they were renting the land behind their house from the council and the deal had ended and the land was about to be subdivided.

So I set about getting the bus ready to drive away, using my Ozito stuff, slowly all but one battery dies, the Angle Grinder cuts out whenever it's on load, had always been like that but thought that's how cordless Angle Grinder work to save the motor or something. Finally it stops as soon as it's under any load, me 357k's from the coast and 255k's from the closest Bunnings and no time to go messing around trying to sort out that problem.

I get by with a 240v 4" angle grinder, one afternoon I wired the Ozito Angle Grinder into 3x6v Start batteries in series that came out of the bus that were holding some charge, had to replace all 4 start batteries, bypassed the circuit in the grinder (it was the problem) and wired it straight to the motor, that worked until one more of those batteries died, threw away the dead Ozito batteries as I could not find receipts and had to get the bus to it's new home, a block of land I purchased up here to build on.

Glad to say I got what I needed done with the Angle Grinder, the bigger diameter disks made it much easier to do several jobs, as said, I could not find my receipts, had taken photos and uploaded them to Google photos, Google photos archived them, found them some time later, I now store receipts on Google Docs as it's easier to find them, all of this is not a slur against Ozito, they probably would have replaced the stuff.

I'm now living Off Grid till the new power pole gets put in (old one condemned) and have had to be inventive on how to charge the power tools and the new Ozito Batteries. After some research I've concluded it's not the quality of the battery, the 18650 cells in the battery are brand name and good quality, the BMS (Battery Management System) is well setup and from what others are saying, I believe it's the 1 hour charger.

The batteries constantly stop charging as they have overheated, which will kill them faster than most things, and they get awful hot, have switched to using an RC charger (Remote Control toy charger) which was going to happen anyway as I have to run the generator to charge stuff. The RC charger I have takes power from anywhere between 7v DC through to 28v DC and the output can be controlled 1-28V, max 2 amps. The thing can be used to balance the cells as well or charge just about any type of battery within it's range including some Lead Acid batteries that still work. My solar system is 24v so the bus alternator can charge the duty batteries during extended rain/overcast periods.

Learnt some stuff, have been investigating and Makita is the best value for money IMO due to there being so many cheap second hand skins and a lot of aftermarket parts and batteries available to buy during those times of low bank balances, am a semi retired and self funded so am not always flush with $

    Thanks for sharing, really, but gotta say: hard to read that text wall.

    TL DR

    Some proper punctuation and a few paragraphs would be good. You'll get a lot more interest that way OP.

      TL DR: OP had problems with power tools but was able to find a work around.

      • OP discovers paragraphs. Still tl;dr.

    Please edit so we can read this. It's like a wall of text.

    Quite a long read :)

    I've used Ozito Power X Change 18V lithium tools at home for quite a while now too. On the whole I'm very happy with the actual tools, all work as advertised.
    I have here, a pole saw, angle grinder, recipro-saw, jigsaw, blower, chainsaw, hedge/grass trimmer.

    At work I have Hitachi and Metabo 18V tools which are excellent but very expensive (owned by my employer). I also use lithium polymer hobby RC batteries for 'stuff' at work and home hobby, and have built my own lithium chargers in the past (back when they cost a packet).

    I've had to replace the angle grinder once, it failed during it's first run, and was replaced quickly and easily by the store. Second one works great.

    Anyhow, I agree that if a lithium battery charger is over heating the packs when charging (say higher than 35C) you are right, they will degrade and also loose cycle life way sooner than they should. I too would ditch that charger and use a slow charger till it's sorted out…

    On the pack choices. In my experience, the low capacity packs lack the 'punch' for the heavier power tools (like the grinder, recipro and chain saw). The internal resistance of small cells is generally higher than the high capacity cells. The internal resistance limits the current flow from the packs, which in turn makes some tools stall (cut out) or just have near useless run times even with the pack freshly charged. You can think of it somewhat like CCA values of car batteries, the higher CCA ones can start bigger engines more easily…

    Sounds like you may already know this stuff so I'll cut it short. In your case I'd buy the largest capacity Ozito packs available and avoid the small ones, I'd always try to use two packs for a job, and not run them down to zero bars on the display. Lithium packs will last more cycles if you don't deep discharge them (like we used too with NiCd or NiMh).

    The other thing I'd do, is repack dead packs with high discharge 18650 cells from a reputable source. I've done that here, and there is an obvious difference in power (not so much capacity).

    OMG, it's a literal wall of text. No formatting, just looks like someone left a word tap running and then went to sleep…

    TL:DR ??

    And I have all Ozito Power X change tools at home and some at work, and never had an issue with any of them. All of them get abused on a regular basis. The only one I ever had an issue with was a circular saw and because I cut about 30km of hardwood flooring. Took it back and it was replaced on the spot with no questions asked. The replacement has worked flawlessly ever since.

    I also have friends and workmates who use this range of power tools and never heard a complaint from any of them.

    • Circular saw is anaemic - getting through that hardwood must have been a challenge!?
      Even doing just a few rips was testing my patience alot 🤷‍♂️
      Are you using the Ultra battery?

      • Seemed to do just a good of a job as the workshop dewalt one was doing. And yes, I have the high capacity batteries for anything tools like that or the grinder. The pissant 2Ah batteries are only good for things like the radio and torch.

        • it makes me wonder if my saw is a dud. It works fine, just weak. I'm using 4AH batteries and it doesn't hold a candle to the 18v Makita I have.

    Must be the device you "wall of text" people are using, I used Grammarly and viewing it on my laptop it looks correct.

    Go have another look on a Monitor

      I think you also spelt your name wrong, I believe it was meant to be Doofus.

      • LMAO ^^^^^^^^

  • I used Grammarly

    Apparently it doesn't know about punctuation and what a paragraph is though eh.

    Fortunately your wall of text was edited which made it a lot more comprehendible.
