Some stores in Brisbane have hundreds in stock - not sure if it recently changed or what.
Not much out of Brisbane though
Thanks mate. Saw that one but I prefer the 4Ah ones. 2.5ah does not last long in my Ozito cordless mower.
2.5Ah is great for short bursty stuff like an impact driver or drill but I agree for anything longer running like the mower you definitely want the extra capacity. Even on my little blower the 2.5ah runs out wayyy quicker than the 2.5Ah.

That makes sense. Cheers
Try changing the 2.5Ah for the other 2.5Ah
I don't mind the 2.5ah for work lights or fan on low. But definately prefer 4ah. Wish they would do more deals with the 5.2ah again. I find I use them the most lately.
The 5.2 are great. I used 2 in the mower, had 2 bars after mowing the lawn. Then moved one of them to the snipper, did the yard, moved it to the blower, did the deck/rest of yard. Then moved it to the portable fan to chill on the deck, ran for 6 hours Sat, 4 hours Sun, still showing 2 bars lol.
@Tarinedier: I've been tempted to try the 8ah, kinda wish they would go on sale once in a while too.
If they replace the 2 chargers with a double charger, I'll get one.
Plenty of stock in Vic , but I cannot get to it via the thumbnail, nor the direct product url ("Oops, this product is no longer available")
https://www.bunnings.com.au/ozito-pxc-18v-4-0ah-battery-mult…Use private browsing/incognito and I can get to it and order - (similar to the last couple of deals)
I'm in VIC and the direct thumbnail/link works for me (Firefox, Chrome and Safari). Maybe a browser/addon issue?
yep you are right actually, I have 2 extensions that have been giving me probs - the penny didn't drop!
thanks GG
Going incognito makes it appear and can be added to cart, but then when I say I want it delivered to Qld, "Item not available for delivery in this area. Please enter an alternative postcode or suburb for delivery."
I would almost get this but I am hoping on some deals with extra skins and batteries. Believe it or not I would like an extra charger or two, crazy I know. I am not up to the stage where I just need batteries yet!
There's gotta be an ozbargainer or two near you with a crate full of spare chargers 😄
I bet there is but thats also why I don't want to get any more, almost guarantee in 6 months I am going to have too many LOL
It's quite possible that the promo dual charger + 2x 4Ah batteries for $99 will come back again.
That's what I'm waiting around for
patiently waiting for another trade in deal for their 5.2ah batteries. Got some in the one in sept and it really does give the extra grunt needed for the steeldeck mower over the 4ah's.
Ozito have/had a trade in deal?
yeah trade in any 18V battery and get $50 off the dual 5.2ah pack was last september. Brought it to $149.
Yeah it was trade in any battery and get 2 x 5.2ah for $149.
Waiting for a similar deal again, loving the 5.2ah's
Don't know how I missed that! I would get on it for sure, I have a few ageing batteries I could trade in.
Shame on fkn Ryobi!
Does Ryobi price match offers like these?
Never. Their range is not budget friendly. If I want good tools its Makita, nothing in between, either cheap lole Ozito or Makita. that's it Roybi is in between and charge you an arm and leg
With chargers can we hack the connections with alligator clips to charge different brands ?
I guess so if you want to risk burning your house/shed down.
Some brands have the battery managment external to the battery. PXC have battery management on the battery.
I would expect bad things if you tried this charger on a battery that is expecting the charger to have the management circuit.
You can hack it , but don't forget the temp sensor. It might be the same type, a 10k ntc thermistor.
Otherwise, to much trouble so you probably bypass it. Which is not wise for a fast charger.
Couple of ideas for your "spare" batteries:
DC Power Supply:

Soldering Station:
Can you help me found an adapter to use this battery on ryobi devices?
Thanks but do you have a link for ozito to aldi ferrex tool adapter? Thanks
@HenryGalilei: Just search on AliExpress - that's all I'm doing. Use "einhell" instead of or as well as Ozito.
https://www.aliexpress.com/w/wholesale-einhell-adapters.html
Nice find on the power supply - have you tried it? Any good?
Are these the ones that catch fire ?
I have 2x 4ah and 2x 2.5ah batteries (all came with kits) for 6 tools including 36v mower. I am managing fine, but if there was 2 pack for $70ish as before, i would buy it as backup batteries.
Nice deal, I used to power the 12V ride-on cars with these batteries
Is it legal/against site terms and conditions to ask if anyone wants to go thirds?
I just need one battery, and this is cheaper than second hand on marketplace. Please delete if inappropriate.
sent pm
Ill get the other one
The other guy was in Sydney, so one is still available, other than yours.
Melbourne, for anyone else interested.
More of a Ryobi guy. It's just my attitude.
Are these good with the Dyson converter to use on V7 cordless vac?
yep, swapped to the ozito converter when our Dyson battery died - works no probs, I use either the 2.5 or the 4's.
Just be aware that the Dyson won't attach to the wall mount/recharger after attaching the converter (if you have/use that)
PSA: using smaller batteries on high-current tools will always be terrible (as in EVEN WORSE than just dividing the capacity).
It helps to visualise it: the small 2.5ah packs have 5 cells, while the bigger packs have 10 or more cells. In order to get 180watts at 18volts, you’re pulling 10amps from the pack. That means 2amps per cell on the small pack, but only 1amp per cell on the bigger pack.
But there’s more! The higher the current draw from a cell, the more the “voltage droop” due to increased internal resistance (this resistance also wastes energy as heat). So the tool draws even more amps to make up for the voltage droop, which in turn wastes even more energy as heat.
The pack voltage drops as its stored energy is used, and all of this stress (more than double on the smaller pack) means it will reach its cutoff voltage when it actually has a fair bit of stored energy remaining. So a high powered tool won’t even be able to use all the energy in the pack.
That said, the smaller packs are MUCH more convenient in low-powered handheld tools like drills and drivers.
TLDR: high powered tools can only access about 75% of a 2.5ah pack’s energy, but 90% of a 4ah pack’s energy. All else equal, the larger pack should also live twice as long.
True but the 2.5AH batteries are 20650 cells if I recall correctly, and are rated 40A ? output and the std 4.0AH are 18650 and are 25A. So a bit closer in capability than say the 2.0AH which are 18650 cells.
I believe the 5.2AH are also 20650 cells and for reference the new sealed batteries and the 6.0ah & 8.0AH and 21700.
Below is the watt output ratings from Einhells website.
I have posted this on prior thread but its a good reminder of the differences in the battery outputs.
2.0AH 450 watts.
2.5AH 720 watts
4.0AH 900 watts
5.2AH 1260 watts
6.0AH 1350 watts
8.0AH 1350 wattsThe new sealed batteries.
3.0AH 900 watts
4.0AH 900 wattsThe recent but now unavailable slim 4.0AH packs are also 900 watts.
What is the internal resistance?
What does a watt rating even mean? Thermal limit? Peak?
Or some efficiency limit?Username Prong explains it way better than I can. Plus he knows way more than my pea brain, He posted a comment in this thread https://www.ozbargain.com.au/node/845022
About half way down.
@revheadgl: I see. It is based on the 2Ah cells being rated at 25A.
The BMU will probably trip if you exceed that, to avoid cell damage.I found I was able to run the ebike on just 2x 2.5ah batteries. Not much range of course, but it climbed the hills.
@revheadgl: God no :)
I added some wiring so I can have a second battery on the rear rack for extended range.
I made a 2x2 Ozito pack for 36V 4Ah. It can slow-charge from the e-bike charger too.@bargaino: Haha, I was curious as I have never seen or heard from anyone that owns one. I hope the Ozito batteries are safe using the e-bike charger, but it sounds like you have it worked out.
@revheadgl: I trust the BMS in the Ozito. Over time, 2 in series may get out of balance, so you should charge them separately once in a while.
The Ozito e-bike looks OK, just overpriced, but poor range with only 2x 5.2Ah batteries. It really needs 4, as I've done.
This guy has 3 in series:
https://www.youtube.com/watch?v=8a6EmokLSx8AFAIK, the only people with Ozito e-Bikes won them in competitions :-)
Are there any Ozito to Ryobi tools adapter? Link please if there's any. Cheers!
Check above - found for Ryobi One so far.
any charger deals?
anyone has link to cheap ozito to aldi Ferrex tools adapter? i have found one in ebay but it's like $40
Yes I'd jump to Ozito if I could find one of these
Looks like some QLD stores have restocked - still won't let me order for delivery, but worth keeping an eye on.
No stock in QLD:(
