I have a 3ah 18v ozito battery. It charges perfectly.When fully charged and I put it in my drill,the drill won't turn on.Drill works because with my other battery it turns on no problem.Would there possibly be a thermal cut off in the circuit board preventing it from working?
As others say these are the same as Einhell certainly looks lke it but that is the only Identical fit one as far as I know. As somone else said, most of these batteries have cell balancing logic in the battery pack now even chepo Parkside (LIDL) ones. Not sure about DeWalt as have not taken one apart but they uniquely have conections for each cell (or cell pair) on the battery and charger and are marked as such. I have changed the odd dead cell which is not easy to identify or do physically in 4000mAh or above packs with paired cells, really have to be careful to chose near identical cless but have had success even soldering rather than welding connections. Good video – saves me taking one apart.
Hi i have a battery pac with 5 s 2p cells and it have 20v but it shows only 2 of 3 loaded led what can be the problem? How can i reset the bms?
A bit late I know, but I got the ozito power station to run my Arduino, BUT it only runs for a few seconds and then turns off. Have I gotten a dud or is there not enough power being drawn to keep it active.
Can these batteries be put in series to get 36 volts
Thank you for the video.Very usefull to me.
I presume the low current source 50ma for the balancing of the cells only actually kicks in once the total sum of all cells reaches 20v..So I would imagine there hard charged up to almost full.. From then on this little unit probably kicks in and trickle charges each cell to 4.2v..
I know my lipo charger for lithium polymer batteries charges very quickly, then at roughly 4-4.1v per cell it actually starts to balance each individual cell.. Literally the last .1 of a volt takes 20 minutes sometimes depending on the size of the pack or the amount of cells..
Just checked all my Aussie Ozito batts brought in the last 18months, none have the EH logo…
so does this mean the chargers are just a power supply and all the peak detection/management is done within the battery itself?
we cant get the car charger in Aust (einhell do sell one but not ozito Australia) and im wondering if i can use a car laptop charger set to the correct voltage (21volts) to charge a battery when camping?
i'd cut the pxc connector off the standard slow charger and wire it direct to the laptop charger. all i need do is double check polarity is correct and the voltage from the laptop charger and the battery circuitry should do the rest?
What is the cut off voltage? If I use it in some projects, how likely it is to go lower than BMS chip is prepared to take it to?
I wonder how long these cells last…I need to re-cell my Blade 2 Max vac…$48 for a 4.0Ah Ozito pack ๐ค
Ozito was the most frustrating a wrong decision I've ever made, have since used a BNPL scheme to purchase a quality brand since the Ozito batteries constantly died even when charged early and kept cool, 3 Ozito tools also died under low loads … even though under warranty I live 98k's which due to some winding roads is up to 1.5 hours each way to the closest Bunnings … to keep using the Ozito stuff I still have I repacked the batteries with Samsung quality cells purchased cheap through Amazon, my Ozito batteries had generic cells, no marking whatever on them.
Nice work. Thanks. Resistors R1-R5 51ohm would be for balancing.
Plz contect numbr
Anyone know which other brands are interchangeable with the ozito pxc batteries without an adaptor? I can't afford to experiment. I have a PXCLMK-1418 lawnmower.
can you please tell me which screwdriver you used?
The original Ozito range was a really cheap and nasty home brand for bunnings but with Einhell buying out Ozito brand to get a foothold in australia there tools have dramatically improved. You still find the original cheap Ozito tools sold and they are still that grey colour but all the red coloured tools are Einhell tools hence the better quality and higher price.
