3s2p 12V Instrument and Robot 18650 cells Battery

*WARNING: Just a single 18650 cell has the potential to start a fire in your home / workplace. Building a battery is a very dangerous task that should only be done by an expert in electricity and electronics.* --------------------------------------------------------------------------------------------------- In this video It is shown briefly the building of a 12V li-ion battery with the 3s orientation. Very compact auxiliar battery made to fit a small robot in which we were working last summer for a robot war competition! This battery consist in a 3s2p Li-ion battery made with 18650 Sanyo GA cells, designed to develop a very high energy density and moderate discharge current. * Important observation: The battery build in this video don't include the electronic protection circuit (BMS) essential for any lithium battery to work correct, reliable and safe. It includes balancing wires as its discharge is monitored by a controller and the charge is done by a balancing charger (SkyRC B6). With Sanyo GA cells It has a energy of 75Wh inside just 300gr. and a raw maximum discharge current of 20A continuously (240W) and 40A peaks (480W). Recommendable average discharge current for lifecycle is 7A (1C). Basic specifications are: - 3s2p 12V 7Ah Sanyo GA cells - Dimensions (max): 70mm x 70mm x 60mm - Weight: 0.3Kg // Volume: 0.15L - Energy density: 640Wh/L // Specific Energy: 245Wh/Kg *info: *Facebook* ► https://www.facebook.com/evmadrid *Instagram* ► https://www.instagram.com/evmadrid *Twitter* ► https://twitter.com/EVMadrid Music: DJ Quads - Chilled #12V #18650cells #battery #build #SanyoGA #spotwelding #custombattery #robot #electronics #lithium #diy #evmadrid
