I have a Pratt Launch box (the one that fills/dumps/ fires Hybrids). It has the battery in the bottom of the box.
Anyone use Lithium Batteries to power launch boxes?
Anyone use Lithium Batteries to power launch boxes?
That is made for 6 'C' alkaline batteries. You must have modified it.
I strongly recommend you add a fuse or circuit breaker to the battery.
Liths are blowing up in hoverboards and Ecigs, they are not to be treated lightly. Shorting out "may" trigger a built in protection device in the battery, but may go to hard open.
OK. Try shorting the clips and firing. Let me know what happens.
I hear ya on safety, but with my limited knowledge of electronics is not the point of a launcher to create a short circuit?
and I would have to continue to depress both momentary switches to continue shorting the circuit?
No, I mean clip the clips together with no ign. A short circuit.
The Boeing 777 was grounded for awhile due to the giant lithium battery
going into flame mode spontaneously.
I used 6 conductor flat satin telco wire with telco connectors for my connection between the handheld launch controller and the box at the pad with a relay. Nothing like being able to lay out a few hundred feet of cable in a walk and pick it up just as fast.
That’s what my launchers use also. At 12 volts it doesn’t conduct well enough for a 1,000 foot run so I plan to make the next version use 48 volts to control the relays.
The relay was not directly controlled by the launch button, so I could use 2000 feet if I wanted to.
As an easy fix for what you already have, you could add a lower current relay at the pad box to turn the power relay on and off. Just a thought...
