![]() ![]() This is wasted as heat, which can damage the cell.Īnd when I state "they max out" i mean they probably won't heat up and catch fire. Current times voltage is power, so it's wasting power. This is set by the cell's internal resistance primarily - as higher currents are drawn, it drops voltage over the resistances inside. For an ebike, it would include maximum current. There's a long list of parameters to consider when it comes to lithium cells. Fine for lots of things, but not capable of electric bikes which have large current requirements. There are errors in the description, which suggests it's unreliable.Īnd these cells max out at 7A according to your linked site. The link is broken because it includes parenthesis, which reddit uses as special characters for links. We are basically looking for a flexible way of regulating output voltage and we would much appreciate it if anyone notices any possible flaws in our project. So the main question is: How can we make the output voltage of ten batteries match the input voltage of 12v and is it possible to find a universal solution for the input voltage? For example if we remove or add a few batteries from the circuite, is the regulated output going to stay the same or will we always be having to use the same amount of batteries depending on the voltage regulation method.Īlso are batteries going to heat up when connected in parallel? Our projector has a input of 12v and 5A DC, while together batteries are going to be having about 42v. With each of the ten batteries having about 18Wh of power, we should be able to get about 180Wh of power in total, which should be enough to keep the projector running for a little longer than 2h (because of the voltage drop at lower capacities). We intend to use 10x jaxman 26650 batteries%20UK.html) connected in a parallel circuite so that we can add or remove batteries by our needs. My friends and I are trying to make a battery powered projector power bank for a 60W projector.
