    B52 LiFePO4 pack

    Yes, for my own use I never bother with BMS... just a decent multipole plug out the pa k and check and balance charge when needed. Bulk charging my 20Ah 20s LiPo at 20 Amps to to about 4.05 volts was my usual way. But for non tech person ... has to be BMS. Need to wait for their decision

    B52 LiFePO4 pack

    Low recovery current at about 0.2 amps for couple of hours.. Yes I know they are toast, no puffed pouches. Current situation with COVID etc..living on the island of Jersey, could be 3-4 months before we could get a new pack.. You know me AmberWolf, I have been here long enough to know about...

    Atmega16 firmware dumping. Win EXE editing etc

    Ok, so not an e-bike question, but this is the only forum I know of, and have history on, and that I know there are people here with potential knowledge to answer. I will make this a long post, by giving the back story first, rather than dive in with my question. This is actually related to...

    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...

    Non EV LED Lighting PSU Question

    If my mate that painted it had been happy with the original built in light system on the lathe, I'd not be doing this We bought it together 3 years ago. Saddle gearbox was shagged...so we stripped it and rebuilt it...But Dave, wanted to make it look shiny too...so he started stripping...

    Non EV LED Lighting PSU Question

    That is how it is at the moment, but was just trying to get it all running off one.

    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

    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...

    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...

    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

    Non EV LED Lighting PSU Question

    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 to 240 All our standard household sockets are 240 V

    Non EV LED Lighting PSU Question

    The newer ones maybe, but I just popped into the workshop, and it only had the standard ‘IEC’ type 240v ac input kettle style plug, there is no other input jack socket Just says 110/240v 18VA So I have ordered a 100VA 380-240 volt transformer from the website I linked to earlier.

    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

    Non EV LED Lighting PSU Question

    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. Was somewhere between 2-5 in the morning, on the phone from bed when I wrote that. So yeah, much lower,, sub 1 amp if not less Yes, transformer, that...

    Non EV LED Lighting PSU Question

    Yes, AC, Measured at spot on 50AC with cheap DVM YEP, understand the RMS values etc and 70 v bc when rectified. Will start searching online for suitable 12v lighting units. Thanks Next issue... The lathe has a Newall Spherosyn digital readout/encoder unit that runs off 240 vac. The lathe...

    Non EV LED Lighting PSU Question

    Quick and simple, cheers My mind was chucking around ideas full of bridge rectifiers, capacitors, Switched mode supplies, voltage convertor boards off of E-bay, 3-d printed cases, hours of stress building , experimenting , cursing and swearing. And you come along and solve the problem with one...

    Non EV LED Lighting PSU Question

    Not EV related... except if you were to say that if my lathe had better lighting, my next hub motor axle might be more accurate ! 🤪 Ok, so I have a Colchester Triumph 2000 lathe. British mains 3phase power, The power socket and cable is 4 pin, being 3 phases plus Earth. No neutral. I...
