Hello friends,

I got a Quadcopter recently and having 7.4v 850 mAh Cell looking Lipo Battery. Apart from that, I already have 7.4V batteries but with more mAh and not cell type. Can I use these batteries to run my machine without issues?

Blue battery is given with Quadcopter, The black one is the one I already have it. Is it okay if I use slim battery?

Machine have space to fit in this slim battery, I think placement is not a big issue.

I am scared to connect it and give it a try, so thought of asking you experts before I break my heart doing something crazy.

My Quadcopter model: http://www.symatoys.com/product/show/1895.html

Thanks in advance

It will work without problems. You'll get longer flight times because of the higher capacity.

It should not be an issue. 7.4 V is still 7.4 V. Your ESC should be able to handle lipo, LifeA123, Lion, NIMH and Nicad. A 7.4 V lipo may hold a higher voltage when fully charged so you may need to know the maximum input voltage that can be safely input to the ESC. I still don't believe you'll have any issues.

Exactly what Eaton said,just don't go too big because the packs get heavy,more weight means less flight times. Try to stay under 1200mah and you should be good,enjoy.

All you need to do is know how many lipo cells the ESC's can handle. You should be at least good up to 3S. If that is correct then out a full charge on the lipo and enjoy yourself. Heed Demetrius warning about the weight. You don't want to lose flight time by carrying too heavy a pack. Considering the size of the pack we can determine that it's a small quad.

Hi..i am a new user here. As per my knowledge 7.4 V is still 7.4 V. Your ESC should be able to handle lipo, LifeA123, Lion, NIMH and Nicad. A 7.4 V lipo may hold a higher voltage when fully charged so you may need to know the maximum input voltage that can be safely input to the ESC.
