WARNING: Just one 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. • ----------------------------------------------------------------------------------------------------- • Building a 48V 42Ah 13s15p 18650 lithium-ion cells battery pack. Made from rejected 10s4p Bosch packs. • 13 serial, 15 paralleled 2850mAh 2C max LG 18650 Lithium-ion cells. • Spot welded 0.15mm x 7mm 99% pure nickel strips. • 30-60 Amps BMS. • 12 AWG Wires. • 230mm diameter Battery Shrink Wrap • 12V - 48V (2s - 14s) configurable battery meter. • 50A anderson connectors for charge and discharge • • *Update: Battery is finally tested. It was unexpected that I can't even notice it is really charging touching at it. It charges at the same room temperature at 0.15C (6A). Discharge rates between 10A - 20A doesn't also reach warmness (0.5C max). Charger (fan built-in) gets pretty hot during CC phase (~5 hours) then only warm at CV phase. • *For EV performance info: Tested 100Km of mixed torture test ride (uphill downhill rush, hard accelerations and slow downs, full throttle half the rode, speed between 20-25 mph, all at night with real 15W lights) then battery Voltage remained at 48.1V that makes a whole 200KM of night hardest consumption range. (EV is not human powered built-in) • • Music: M83 - Midnight City • info: / 813088912108985 • *extended build info brief article on electricbike.com : https://www.electricbike.com/home-bui... • --------------------------------------------------------------------------------------------------- • Facebook ► / evmadrid • Twitter ► / evmadrid • Instagram ► / evmadrid • #48V #2kWh #DIYbattery #18650cells #spotwelding #massivebattery #oldschool #vintagebattery #Nobuo
