Hi,
I have some 18650 flashlight, and the following batteries.
I have the following lights, batteries and charger:
- 2 x AW 2900mah protected cells which I use in my twin battery Skayray STL-V2
- 2 x Solarforce L2P with Manafont XML dropins
- 1 x Ultrafire 502b with XML it came with from DX
- 2 x Trustfire flames protected 3000mah
- 2 x Trustfire flames protected 2400mah
- 2 x fake Sony protected 3000mah
- 2 x Ultrafire blue protected 2400mah
- Pila IBC charger
I have some concerns regarding exploding and venting with flame batteries and therefore have purchased some AW's for my twin battery Skyray.
I always watch the charger while I am charging, and touch the charger and batteries to ensure they are not getting too hot.
I use a Multimeter when I take batteries out of my flasdhlights to ensure that I haven't over drawn them, and like to keep voltages above 3.6V
I also take a multimeter reading straight from the charger, and then let the cells rest for an hour before re-testing the voltage and then using in the flashlights.
I have small children and therefore am a little paranoid about having any issues with the cells.
Do you think I should replace all my cells with good quality Redilast or AW cells, or just keep the cells I have and just be vigilant and keep using the same charging and testing regime I am using to ensure I am not overcharging my cells.
I have another question in relation to how cells will explode of vent. Does it mostly happen in a charger, when the cells are over charged?
Can it happen with a single cell flashlight, and if so, what sequence of events causes this to happen?
Is it by over drawing current from the cell, or using it when it's at a lower voltage?
Also, will a short between the strip that runs on the side of the protected cell is exposed and touches the body of the flashlight? Will this cause an cell to explode?
Should I just dump the cells I have and replace them with good quality ones, and be done with it?
I don't mind doing that, if it's going to mean that I won't have issues with venting or exploding cells?
I can tell that the AW cells I have are really well put together, and the wrapping is thick and strong. The fake Sony's I have have had the strip from the PCB to the positive end of the cell already pierce through the wrapping around the cell after about 2 weeks of use. Is this dangerous?
All advice is welcome, as at the moment I am a little concerned about the dangers of using these cells.
Cheers
Rob
