-Hi guys, I have to find a solution for the project I'm developing which consist in 1 arduino uno, 12V stepper motor, 1 miniservo and 1 lcd shield. My problem is how to supply the energy in order to make it as portable as possible: the idea is to make it fully indipendent from external energy. Of course the first Idea is to use a rechargable 12 Volt battery (possibly cheap and small). So, I'm very ignorant in this matter, I don't really know which kind of battery I would need or if there are limitations, I just like to know what you think about the battery I've found here:http://www.diotronic.com/alimentacion/pilas-y-baterias/baterias-de-plomo/bateria-800ma-12v-96x25x61-5_r_358_8434.aspxhttp://www.diotronic.com/alimentacion/pilas-y-baterias/baterias-de-plomo/bateria-800ma-12v-96x25x61-5_r_358_8434.aspxAre they compatible with the project I'm doing? Then do you think is it possible to recharge it with a common DC 12V power supply? or do I need something different? or maybe I'm totally wrong?Thanks a lotjd
It may be an old technology, but I have come to the conclusion that I like using lead-acid batteries. They are a lot less fussy about how they are charged than NiMh's or LiPos. I used them in my solar radio (http://srmonk.blogspot.com/2011/09/arduino-solar-radio.html) mainly because they are quite happy being trickle-charged with a current that frequently varies by a factor of 10 depending on the weather (I live in England).
