Sorry for the novice question, but I am thinking there should be a simple solution. I work as a magician and purchased an effect where a snake puppet in a basket goes up and down on a battery powered telescoping linear actuator. It's operated by a wireless remote. Here is what I know, the two button remote (up and down buttons) uses a 12V 23A type battery. The receiver for the remote (in the the snake basket) also uses a 12V 23A type battery. There is an on/off switch in the basket to turn the remote receiver off. Here is what I think I know-the motor that drives the snake up and down must be 18V-I am pretty sure it is powered by 2 9V batteries. The problem is that 12V 23A battery that supplies power to the receiver just doesn't last-even with keeping the switch off, it get through about 2-3 shows, maybe 15 up and down motions and the battery quits-once it drains down to ~11.5V-it's done and that snake ain't moving. Any ideas on a better solution to power the remote receiver? Is there a better choice of battery? There is lots of space in the basket so the small footprint of the 12V 23A battery is not important. Here is my concern, 8 AA batteries will generate a lot more current than the 12V 23A-will the extra current blow the remote? Or will a rechargeable 12V 600mA NiMH battery be the most robust option? thanks for any help...

The 8 AA cells can produce a lot more current than the 23A battery, but the receiver will only draw the current that it requires - the larger battery will not force excessive currrent into the receiver, providing it provides the correct voltage.

  • \$\begingroup\$ thank you Peter-really helpful-so using 8 AA batteries should last longer overall-will probably go with a rechargeable 12V NiMH 600mA battery. thank you again! \$\endgroup\$
