    Well not necessarily of course, but he linked to banggood so I thought there will probably be 5 series boards as well, and this was the better looking one of the 2 options to be honest... Could you link me a good starters board, for 5S and about 15-30 A?

    Making a battery to charge my laptop on the road

    Would it be possible though to change the current 18650 cells in my laptop so that it just has a larger capacity, currently there are the Samsung ICR18650-22F in there, these are 2200mAh and 3.6 v and 4.4 A. Could I replace those with the Samsung INR18650-35E, these have a larger capacity of...

    Making a battery to charge my laptop on the road

    I would love to get a second battery for my laptop, but the problem is you can't just pop it out of my laptop and back in. I would have to unscrew about 15 screws and take off the complete backside of my laptop.

    Making a battery to charge my laptop on the road

    I just looked which batteries i currently have in my laptop which are 6 samsung ICR18650-22F cells. If I could buy a device that can charge 18650 cells and buy some 18650 cells (the same or maybe Samsung INR18650-35E because they have a larger capacity and the same voltage) and a "holder" like...

    Making a battery to charge my laptop on the road

    It doesn't have to be super cheap, I just saw that 12 volt battery packs are very expensive and you would still have to buy a car charger to buy it. Also I think it would be nice to learn more about how all the different component work and how it works together.

    Making a battery to charge my laptop on the road

    I don't mean necessarily in a car, you could also be traveling by plane or in a train. That's the reason I want to make a battery pack. I would like to know how I could make a proper charger for it.

    Making a battery to charge my laptop on the road

    I would rather just make a battery pack my self to reduce costs. The 12 volt batteries are often very small in capacity and are very expensive. I know how to wire batteries up but I don't quite know how a device reacts to a certain source of power. (Especially how amperage works, I understand...

    Making a battery to charge my laptop on the road

    Hello everyone, I guess I am a total noob when it comes to knowing how power works. I want to create a bunch of 18650 cells, they are 3.7 volts. I want to put every 5 in series so that i get 18.5 volts to charge my 19 volts laptop(I guess this is not a problem, if this can a problem please tell...
