Am building a wireless robot and i want a good decent battery for that. I am taking in use 12v 1.2amps battery, it’s too big in size and heavy too. So, please suggest me an alternate battery for this, which should have somewhat same configuration and lightweight and also bit small in size.
@Suraj We would need to know a lot more about your setup in terms of components. Please create a new topic on the RobotShop Forum and provide as many details as possible.
Hi i have ultra spike dinasour fisher price the issue is when it move it stop when i restart using power switch everthing work again except if i command to walk it stop this has been the common issue for this toy one guy says he replaced the the battery with the higher volts and it work again my question is how far i can go up with the required battery which is 9.6v,1300mAh to avoid the short circuit thanks!
@Chad It’s best try the same battery as was suggested by the person who hacked the product - it’s a question of what voltage the electronics can tolerate.
I’m confused by the nominal voltage. I have two 4.5 6S 22.2v high discharge LiPo battery and i need to power a 24 V hub motor. I read that the cells can be charged up to 4.2V, what does that mean?
A 6S (six cell) pack contains six 3.7V (nominal voltage) cells. When charging, a charger will charge each cell to around 4.2V, so the total pack will end up providing 25.2V for a while, rather than 22.2V.
Hi. I’m using 4-6 k2 waterproof high torque servo motors. What would be the best batteries for me to use?
I need to charge my i)1000KV brushless DC motor and propeller ii)4 servo motors for wheels.please suggest the needed Li Po batteries
@Sucheta Normally BLDC motors need 2S, 3S or 4S LiPo, while standard RC servos operate at 4.8V to 6V. You should therefore choose high voltage RC servos and a 2S LiPo pack (assuming the BLDC motors operate well at 7.4V.
@Dwayne Unfortunately we are not aware of these servos to know the nominal voltage, though it’s likely 4.8V to 6V (please confirm though). You then need to check the max current per servo, then multiply that by 4 to 6 to get the max continuous current required by the battery. The last selection is the battery’s capacity in order to know how long the servos will last between charges.
I’m using 4 Johnson [ 800mA 12 ] for robot ~ i want to make portable which battery should I used
@Nishadvijay You need a battery which is at the nominal voltage of your motors. If 800mA is the continuous current under load, the battery needs to be able to provide at least 2.4A continuously. The capacity is a measure of how long the battery will last between charges.
hi sir , we use 24v 250 w dc gear motor for our project , so sir for minimum 1 hour riding our vehicle which battery we select ?
@yogeshkumar pustake It sounds like at maximum power, the motor would consume 250/24 = 10.4A. If you use two motors, it would double up to 20.8A. For 1 hour ride time, you would need a 24V 10.4Ah battery for one motor, or 24V, 20.8Ah for two. There is a lot more involved like efficiency etc., but this should give you a ballpark estimate.
can i know how long does the 9V battery can be used for 12V motor
@Muhammad Syahir If you mean a normal 9V battery, which tend to have up to 150mA capacity (maybe a little more), it won’t last long at all when used to power devices other than electronics.
can you charge a 12v, 1.3 Ah Li-ion battery with a 12v dc 500mA charger
@marvin youngstrand Normally a LiPo would be 11.1V rather than 12V. You really should choose a LiPo compatible charger (LiPo batteries are dangerous) and ensure the charger is compatible with 3S LiPo batteries. If your battery is special and is 12V nominal, you would need to consult with the manufacturer as to how to charge it.
Hello Sir, I am working on a Project. I need 6, 12 volt Dc Motors. But I m confused about The battery. Can u please help? ?
Hello Sir, I am an engineering student. I am working on an agriculture robot. I need 6 noS. Of 12v dc motors. But I am confused about which motor should I use.? Can u please help? ?
