I certainly hope so, as it's hard to tell under the wrap.
Why Use Unprotected While [SIZE=+2]Protected Works Fine?[/SIZE]
Why Use Unprotected While [SIZE=+2]Protected Works Fine?[/SIZE]
Regarding the Darwin Award and Intelligent User comments, would you hand a light with unprotected batteries to a child, or to someone who was an otherwise responsible adult but wasn't into geeking out on electronics and battery chemistry?
- Say for instance in the unlikely situation where the light was a tool that needed to work without being a distraction regarding its own special needs.
If current protection kicks in too early, then it does not work fine.Often current protection kicks in too early,
So your unprotected cells are for your own use only.ChrisGarrett said:I don't any longer buy protected cells for my personal use.
Why don't I use protected cells? There are several reasons ....
outstanding summary and post, Matt, thanks[emoji106]
Seems like you never pay attention to question. If protected cell can't provide current demand, then you can't use it. Then we don't have a question. You have to find another solution. You have to use unprotected or even IMR. We all understand that and we are assuming a protected cell works [SIZE=+5]FINE[/SIZE] (without any problem) in any specific flashlight. In this case, why use unprotected?I had only issues with them when protection kicks in because the light wants more current during its normal operation (the battery discharges, voltage goes down, regulated driver tries to pull more A —> hello darkness).
If a PCB failed in a cell, you will throw away $10~15 and get a new one. Can you do it if you or your loved one injured from unprotected?I used to puirchase only protected cells until three or four PCBs failed in about a month. What with that and being left in the dark, I'm all IMR and INR now.
There is no problem with this but is there any problem with a little extra care?I take care of my cells and use decent chargers, I see no problem with this.
If a protected cell has electrical short circuit, there is a chance that PBC block the current flow but the chance for unprotected is ZERO. In this case, BOOMIf I lend a light to someone who is uninitiated, how can they do themselves harm with an unprotected cell in a light without LVP? If they run the cell past safe discharge, the only way to cause a fire is if i recharge it.
