I am powering a 6 V 1A push-pull solenoid using a 9 V 1Ah rechargable lithium ion battery (form: 9 V alkaline) using a relay; the 9 V is stepped down to 6 V; controlled by Arduino. It is to be used as a kicker for a robot. The force is weak, perhaps less than the 5N advertised, why? Is it because the current draw is low (i.e. far less than the rated 1A)?
What can be done?
- Should I use 9 V without stepping down?
- Use a capacitor to store charge, and then discharge, so the current supply will be ~1A?
- Can >1A of current be supplied to the solenoid for a short duration?
- Should I get another solenoid, maybe a 12 V 1A?
- If I should use a different power supply, what can I get that is small? I have a bunch of 3.7 6.8Ah li-on batteries around.
