- 29V batteries have very low current source capabilities. Your motors will work, but they will be "weak" once you apply loads to them. They will seem fine without loads.KyranF– KyranF2014-09-22 16:23:20 +00:00Commented Sep 22, 2014 at 16:23
- how are you running the motors anyway? digital HIGH or using PWM?KyranF– KyranF2014-09-22 16:24:23 +00:00Commented Sep 22, 2014 at 16:24

- 29v "transistor" batteries are rarely suited for motors, and generally a poor choice for the arduino itself. Even with a lower impedance 9v supply, your 12v motors would probably perform poorly with only 9v in and the motor shield itself loosing at least another volt.Chris Stratton– Chris Stratton2014-09-22 16:46:48 +00:00Commented Sep 22, 2014 at 16:46
- 1Disconnect the motors and battery from the motor shield. Then do these tests: 1. When you connect your 9V battery to one motor, does it run much more quickly, and well enough? 2. When you connect both motors to the battery do they run okay? If either answer is no, then the current approach is not going to work. Even if it is okay, the Arduino motor board will reduce the battery voltage, making things worse.gbulmer– gbulmer2014-09-22 18:28:58 +00:00Commented Sep 22, 2014 at 18:28

How to Edit
- Correct minor typos or mistakes
- Clarify meaning without changing it
- Add related resources or links
- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
- create code fences with backticks ` or tildes ~ ```
like so
``` - add language identifier to highlight code ```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible) <https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. arduino-uno), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
