Does anyone share my concern that there is not enough emphasis placed on the safe usage of Lithium batteries - given how much public proliferation there is an DIY hobbyist activity.
Im sure most viewers here will be well aware of the high profile Lion battery fires, burning down houses etc plenty to see on Google and YT.
What is alarming to me is the numerous YT vids of rank amateurs/informed persons who should know better messing around building battery banks on kitchen tables without realising the risks and the inherently bad practices they are promoting.
Those little batteries look so harmless and inoffensive lying on a bench - dont they.
IMHO the experimenter should be approaching the topic with the same dedicated care you might devote to building an IED land mine.
Way too OTT you might say - till you see how many silly mistakes are made with accidental short circuits, blowing things up etc - all because of careless hasty quick fix practice (we all do that dont we?)
Its the in built belief that we are dealing with ELVs 12-48vdc so not a shock hazard in the code sense (not always true btw ask a sailor).
But its the hidden potential for large stored energy releases suddenly in bursts of 1000's even 20,000 Amps, causing fire, explosion, Arc Flash - instant damage to unprotected skin and eyes from UV and arc spatter. Think of a stick welder arc x 1000. This is to put the topic into perspective and maybe at the extreme end of what can happen in practice.
Do you need to be aware of the risks?
Why do you build Battery banks, wiring, exposed live parts etc and messing with them so blatantly?
Would you do the same thing if these part were live at 240v or higher? See what I mean guys?
IMHO as a responsible forum
we should develop a sticky on Safe Practice for Lithium Battery Banks here - cos I haven't seen one anywhere else
