Since the charger will be made of aluminium, the constant current linear FETs that will be used will need to be cooled, since they can output around 17W firing on all cylinders.
Edit: The MOSFETs will be used in full saturation mode, to use them in a linear fashion to replace discharge resistors.
Hello again guys and gals. BlueSwordM here.
So, I've noticed something interesting here.
Over on BLF, a flashlight forum, I've decided to start on the journey of making a product in a domain from which I have a lot of experience in.
In this case, it's flashlights,batteries, and chargers. So...
CO2 will NOT work to extinguish a lithium-ion fire, since during thermal runaway, the cells supply their own oxygen.
You need to make a sand pouch which will open during excessive heating, or just spray with water and pray you can recover some cells.
Is there a reason that they are so vague in their statements of the regulation?
I think the definition of reasonable should be that you take your own risks into your own hands, and that if you want to have certification or insurance, you have to be evaluated fairly in your aptitudes and builds...
1. A white box.
2. Active ventilation inside of that box using a 120mm/140mm, or if you have the space, a 200mm fan.
3. If you want to make it a permanent pack, fill the pack with a phase change material, like high melting point paraffin wax.
These 2 last ones are extremely...
