Hi there!

Based on your description, you’re comparing the recommended battery for the AdventureBot/JD Humanoid-a LiPo 1300mAh 2S 25C with dimensions 70 x 35 x 10 mm-to an alternative LiPo 1300mAh 2S 30C that’s 70 x 34 x 14 mm.

Here are a few points to consider:

1. Physical Fit:
   The alternative battery is 4 mm thicker (14 mm vs. 10 mm) while the other dimensions are very similar. This extra thickness may cause a fitment issue if the battery compartment was specifically designed for a 10 mm thick battery. I recommend measuring your AdventureBot’s battery bay (or checking the manual if available) to ensure there’s enough clearance. Even a couple of millimeters difference can be critical in tightly designed compartments.

2. Connector Compatibility:
   Check if the alternative battery’s T-Plug connector matches the battery connector used on your AdventureBot. Sometimes, even slight differences in the plug type or wiring configuration can require an adapter or additional modification.

3. Performance and Ratings:
   The alternative battery has a 30C discharge rating instead of 25C, which means it can deliver a higher current if needed. This is generally a good thing-as long as the robot’s electronics and servos can handle the potentially higher peak currents without issues. The 1300mAh capacity remains the same, so runtime should not be affected.

4. Mounting and Securing:
   Consider if the mounting points or brackets in your robot are adjustable. If the battery is a bit thicker, you might need to make a minor modification to secure it properly and prevent it from moving around.

If you’re comfortable with a little DIY adjustment, the alternative battery may work fine-assuming you verify the physical and connector compatibility. If you’re unsure about the available space for that extra thickness, you might consider reaching out to the AdventureBot’s documentation or double-checking the battery compartment dimensions before making any modifications.

Does your battery bay offer any extra clearance, or is it a snug fit for the recommended dimensions? Let me know if you need any further details or guidance!

so can jd servo's handle the batterie LiPo 1300mAh 2S 30C that’s 70 x 34 x 14 mm ?

Hi Nomad_6R,

In general, the JD servos (and the rest of your robot’s electronics) are designed to work with a 2S LiPo battery, so the voltage and capacity of a 7.4V 1300mAh battery remain within the specifications required.

Here are a few points to consider:

• Voltage Compatibility:
  Both the original and alternative batteries are 2S (7.4V nominal), which is what the JD servos and the robot’s power system are designed for.

• Capacity & Discharge Rating:
  The 1300mAh capacity is the same, ensuring similar runtime. The alternative battery has a 30C discharge rating instead of 25C. This means it can supply a higher peak current if needed. The higher C rating isn’t an issue for the servos themselves; it just means the battery can handle heavier loads without voltage sag. Your servos will draw what they need, and they won’t be "forced" to take higher current than designed.

• Physical Considerations:
  The only other concern is the physical dimensions. The alternative battery is slightly thicker (14mm versus 10mm). While this won’t affect the electrical characteristics, make sure the battery compartment in your JD Humanoid or AdventureBot has enough clearance to safely accommodate the extra thickness without causing any mounting issues.

Overall, yes-the JD servos can handle the alternative battery from an electrical and performance perspective. Just double-check the battery housing or mounting bracket to be sure it fits properly.

Does this answer your question, or is there anything else you’d like to dig into about your setup?

@athena

that anwers my question , i will by one see if it fits . if it does i post it here .

thank you

I'm glad to hear that helped, Nomad_6R!

Please keep me posted on how the battery fits in your AdventureBot or JD Humanoid. If you run into any other questions or need further guidance on your setup, don't hesitate to ask.

Happy building!
