Which battery-pack should I use?

Help & Support Robot Parts

Hi,

(this might not be the perfect section to ask, but this is really a simple question - I need to know, since I have no experience)

**If suppose, I have to build a Quadrapod using 26 Hitec (standard) Servos [most of them running at the same time] controlled using Axon Microcontroller…
Which Battery-Pack would be the most suitable?

  1. 6.0 Volt Ni-MH 1600mAh Battery Pack
  2. 7.2 Volt Ni-MH 1600mAh Battery Pack

Thanks.

Well, my robot won’t require enough run-time, I would prefer 1600mAh… but I want to know, can the Hitec HS-422 Servos support 7.2 Volts Battery-pack? … (because I might have like 12+ servos running simultaneously with full speed) - OR - would you suggest I use 6.0V 1600mAh ?

Please [POLL] - Thanks**

I think a lot depends on what servos you choose. Some can handle 7.2 volts without problems, others may not. Also not sure how long 26 servos running at the same time will last on a 1600mah battery.

Looks like the 6v packs work fine for what you want to do. Here is a video of a hex with what looks like a 6.0 Volt Ni-MH 2800mAh battery pack being used.

Yeah you,left off one criteria. Run time. If 10 minutes is enough the 1600 might work, but if you need longer run time 2800 is the answer.

The difference in volts do not really matter. if you are talking run-time then you will want the 2800mAh batteries. they have twice the capacity as 1600mAh batteries, therefor, last twice as long. :slight_smile:

EDITED (above)…

Please [POLL] with your opinions.

Thanks !

The 422 handles 7.2vdc pretty well. That being said, it is considered abuse and is likely to reduce the life of the servo. We have run the 422 at 7.2vdc with our older EH2 Hexapod walker. Sorry there was no voting option that included a disclaimer.
