AW, cheers.
Yes understand your points,
Interesting about Ping packs...
Is he still about ?
If I get the Steslth pack here and open again, I’ll photo the BMS and read label on cells

Re: B52 LiFePO4 pack
Yes of course if a pack has a non-adjustable BMS whose "start-balance voltage" **requires** going higher than 3.45Vpc then you have to choose between letting a crappy BMS dictate your charging profile at the price of reducing pack longevity, or replace the BMS, or use something else to do...

Re: B52 LiFePO4 pack
Ok thanks Will see what the owner decides to do I will e-mail him the link to this thread so he can read up on it all and decide. He may just ask Stealth to send new battery and charger or we may build new pack ourselves....Angus.... over to you and Oz to decide... new pack needed .... what you want...

Re: B52 LiFePO4 pack
So , yea, thanks AmberW to Sum up..by bad..posting when tired. and being lazy..I already admitted that :roll: Yes LiFePO4 pouch cells, 24 series and 3.65 volt per cell gives the 87.6 as on the charger. So all good. As long as the pack does not pop. He know he has to buy new pack and charger...

Re: B52 LiFePO4 pack
So I pull the pack and strip..start checking cell voltages....yes all way too low..0.99 1.4 etc etc. Well, those cells are toast. I wouldn't recharge them, but since you've already done that, I wouldn't allow them near a building or anything else, especially if they actually are RC LiPo types. But ...

Re: Non EV LED Lighting PSU Question
I've been looking through RS. Some little ones there , 440-430-420-410-400 type input tappings with labelled 230 out. as opposed to the one I bought from ETE, single in single out 415 in 240 out. With the RS one gives the chance to connect to higher input windings so lowering the output voltage. Rat...

Re: Non EV LED Lighting PSU Question
Ah yes, nice idea
Thanks
Will try that when I get home
Should of thought of that myself, as an extension to my own thoughts. I was thinking I need to load it with a bulb or make sure to power in other stuff first
Got plenty power resistors kicking about

Re: Non EV LED Lighting PSU Question
Already have enough 240 volt outlets on the wall, That is how we currently do it. Just wanted to get it all running off of one single feed. Alternatively I could run a new 5 wire three phase supply, to bring a neutral to the machine as well to give direct 240. But was trying to do it with as little ...

Re: Non EV LED Lighting PSU Question
OK, so I ordered one of these.. https://www.ete.co.uk/product/transformer-415v-to-240v-25va-single-voltage/ and it arrived. Tested it out, but because it is a transformer and its no load voltage being higher until load is drawn ..it is useless for me....bugger. Its no load output is 267 volts. Stick...

Re: Non EV LED Lighting PSU Question
Have ordered a 100VA 380-240 transformer
Would have liked bigger, but want to fit in existing box if I can
Encoder is 18 VA
Looking up LED lighting strips and swan neck units now

Re: Non EV LED Lighting PSU Question
What do you get if you measure between 2 phases of the 3 phase supply? Between phases will be single phase. 400 volts. Was To get standard 240 volts I need the neutral line too. Think in USA your single phase might be across two phases of your 3 phase, but over here we need the neutral to get down ...

Re: Non EV LED Lighting PSU Question
It is 240 vac input
Have been looking at other transformers
https://www.ete.co.uk/wp-content/uploads/2016/10/WV.pdf
Think if I got a 380 In 240 out, I could then run any lights with a 12v Switched mode type supply, and run the Digital display too

Sorry, absolute Max would be 3 amp, simply because it has a 3 amp fuse in its standard UK 3 pin plug. As you say, probably much much less.
