Lot of good choices here, this one seems ideal https://led.meanwell.com/webapp/product/search.aspx?prod=LPC-150 or this exterior rated one https://led.meanwell.com/webapp/product/search.aspx?prod=ELG-150-Camberwolf said:Meanwell makes other LED PSUs that may also work

flippy said:meanwell HRP-300-48 is the flattest you can get. its 40mm thick (that is like 1.5 freedoms i guess) and has active cooling towards 1 side so you can squash it between things. the ELG/HLG models need space as they are passivly cooled. its also half the weight
forcefed said:Hmmm that's a good idea, didn't think you could do that. There's plenty of $10 42v 2a chargers out there that you could run in series, just not sure that's a good idea with those ali express chargers :lol:
Generally, those aren't made to do that. You can try it...but my guess is you'll get smoke because they're not isolated input to output. Sometimes you can work out the circuit paths inside to isolate one side from the other, but someitmes it's designed in a way that requires this connection.forcefed said:There's plenty of $10 42v 2a chargers out there that you could run in series, just not sure that's a good idea with those ali express chargers :lol:
That one only works above 180VAC, so unless you're not using it on regular 110/120VAC outlets, it won't be useful.Lot of good choices here, this one seems ideal https://led.meanwell.com/webapp/product/search.aspx?prod=LPC-150
The ELG is basically the same as the HLG, made a bit more cheaply, and with less high power versions. https://www.led-drivers.com.au/blog/mean-well-elg-led-drivers-vs-hlg-led-drivers and https://ledgardener.com/forum/viewtopic.php?t=1289or this exterior rated one https://led.meanwell.com/webapp/product/search.aspx?prod=ELG-150-C
It's not so much the water issue that the exterior ones are good for, it's that the potting that makes them waterproof *also* makes it effectively impossible to vibrate or bang them to death like will happen with stuff that does not have all the parts secured down against this. (like the cheap chinese chargers, which can literally fall apart when carried around on a bike...they might not...but it has happened).Wonder if i would need the exterior rated one, i don't ride in the rain and my battery bag is water resistant.
I'll save the psu experiments for a dinky hoverboard battery pack, i won't experiment on mine, paid too much for it.amberwolf said:Generally, those aren't made to do that.

There's a lot of possible devices that *might* work...but the HLGs *do* work.
Lol good catch, funny that the 100w version does work at 120v https://led.meanwell.com/webapp/product/search.aspx?prod=LPC-100That one only works above 180VAC, so unless you're not using it on regular 110/120VAC outlets, it won't be useful.Lot of good choices here, this one seems ideal https://led.meanwell.com/webapp/product/search.aspx?prod=LPC-150
Good info thanks.The ELG is basically the same as the HLG, made a bit more cheaply, and with less high power versions. https://www.led-drivers.com.au/blog/mean-well-elg-led-drivers-vs-hlg-led-drivers and https://ledgardener.com/forum/viewtopic.php?t=1289or this exterior rated one https://led.meanwell.com/webapp/product/search.aspx?prod=ELG-150-C
I dont want to bolt it outside it'll ruin the aestheticsIt's not so much the water issue that the exterior ones are good for, it's that the potting that makes them waterproof *also* makes it effectively impossible to vibrate or bang them to death like will happen with stuff that does not have all the parts secured down against this.

But the waterproofing means you can actually bolt it to the bike itself, like a controller, and leave it there all the time, if you charge by parking near an outlet.
Each of these has a different total power available. The 100 is "100w" (roughly), and the 150 is "150w". So if you have the same voltage on either one, the higher wattage can have a higher current.forcefed said:So its either lpc 100w or elg 150w, funny how the spec sheet says the lpc will charge at 1amp and the elg at 1.75amps. Is it because the lpc has a higher voltage region, up to 96v while the elg up to 86v?
