Hi Folks - I came across this thread when searching for LEDs and 40v Batteries. Hope it's not bad form to resurrect an old thread.
Dale - I was curious if you ever came up with a use for your 40v batteries? I was given a set for a snowblower that I'll probably never use, at least during camp season, so I thought they'd be perfect to run lights. I was surprised to see they were 40v! I've tried running some LED strips from my 18v drill battery, which works well, but they seem hot so I suspect I could be running the risk of burning them out, and that would be much worse with the 40v. It seems one way mentioned to get over this would be to add extra strings to increase power demand. I'm lighting a schoolbus, so really any extra strings and i'm now trying to figure out a dimmer
Was there an easy way to step down the 40v to 12v? The idea of a computer PSU is interesting, I have lots of old ones about.
Also would love to hear if anyone has any other ideas for how to leverage power from 40v batteries. I'm off grid so there are lots of potential uses. Probably mostly in lighting though, not into water pumps just yet. I wonder if there is a way to wire a small solar panel into the 40v battery and run a shed light or something like that...
Anyhow appreciate any thoughts.
Thanks.
