Top or Bottom Loading Battery - Any Ideas?
Posted: Wed 7. Mar 2018 16:55
I’m designing a new chassis to convert very small 1/32 scale slot cars into magnetically guided magracers using 2.4ghz radio components. It will use the standard magracing motor (which has an uncommon 1.5mm output shaft), one 10440 (AAA) 3.7 volt li-ion rechargeable battery, and an HK-5320 servo for steering.
I’m trying to figure out how to make a bottom loading battery “box” that does not require magnets to hold the battery in place. The magnets take up too much space. In the case of top loading battery boxes on my LMP chassis, gravity and the flexibility of the plastic hold the battery in place. In this new short narrow chassis, top loading doesn’t work so well.
The battery will be located transversely very close to the motor. Thus the length of the battery determines the minimum width of the chassis, at least back near the motor. If the battery is loaded from the top, then the wires connecting the motor to the electronics board in front, have to go underneath the battery or around the ends of the battery. Neither is desirable.
Do you have any ideas on how to hold a battery in place when it is loaded from the bottom? Cannot use disc magnets like those used in typical magracers. Perhaps some kind of temporary adhesive could be applied to the surfaces of a tight fitting box. Any ideas would be appreciated.
