@akshay You would ideally an 11.1V or 12V battery which can output at the current needed by all six motors at their peak. The capacity will determine the time between charges.
@akshay Feel free to create a new topic on the RobotShop Forum detailing your project and what you need help with.
Hello. Thanks for your very useful post.
I am currently working on a very low power device logging data from a GPS chip three times a day. I would like to have it running for 1 year at least. What kind of battery/technology would you recommend me? size and weight matter (as small and light as possible) but price does not!
Thanks!
@Arnaud If it needs to run for a year without the chance to recharge (solar panels or wind turbine for example), most normal batteries would discharge over the course of a few weeks / months (certain exotic Lithium based battery tech may last longer). You might consider changing the technology used entirely and consider a hydrogen based mini fuel cell, which charges a regular LiPo battery. If you need more advice / ideas, please create a new topic on the RobotShop forum and provide details of your project.
Hi,
I am currently building a project where I require to power two 12 V dc gear motors(pololu) with stall current at 5A. I planning to use a 12 V 9Ah lead acid battery for my project. The motors will be connected to a motor driver (L298N) that is rated for 4-40 V, 2 A. Now I am not sure if I should connect the motors to the battery without damaging them. I am very new to electronics and really stuck. I have been testing my project so far using a 12 v adapter running on AC. Please help or suggest something.
Thanks
Alex
@Alex You would connect the battery to the motor controller, not the motors directly. The battery may be on the heavy side if it’s a mobile robot.
hello there, I have a robotic arm and I`m using 2 MG996R servos and 5 MG90S micro-servos I want to use the best battery that can last over 5 hours or even longer .I was going to use a powerbank with 5v and 20000mAh but then I knew that its maximum output current is 5.5 A . can you help me to choose the best battery or power source for my robotic arm .
sir which battery should i used for operating 4 servo motor simultaneously???
Hello Sir,
Are there any disadvantages of using a regular powerbank and steping up the voltage with a boost converter?
hello
I am using Two motors of 250W, 48V hub motor .
can you tell me how much battery i need and calculation also?
@brijesh If they are normal RC servo motors, you can use a 6V battery. The capacity will determine how long the servos can operate between charges.
@Simon Not sure what you mean by a “power bank”. Normally you tend to reduce voltage rather than step up.
@Arifa Fatima The current is likely ~5A, so you need a 48V battery which can provide at least 10A continuously. The capacity will determine how long the motors will last between charges. However, without additional specs for the motors, we cannot be certain they will not draw more than 5A. You really need more info.
well done sir, i can see you are really doing a great job. please i want to know if using 3 of my 3.7v battries would be okey for a 9.6v motor
Hiii… i need to know which battery suits for two stepper motors of 3.3v. And how many hours does it works if once full charged…
@Manohar You might try a 3.7V LiPo. The capacity will relate to how long the stepper motors are powered between charges.
Hello! I would like to use 2 12V 970RPM Econ Metal Gearmotors for trolley. Which battery would you suggest? Thanks in advance!
@Gulzat What is the operating current under load, how many motors do you have any how long would you like the battery to last?
