Using Second Life 18650 cells, one of our customer was able to create a custom DIY portable power station for recharging Radio Controlled (RC) vehicles at his RC flying club:
"Portable battery packs, all made using recovered 18650 INR cells. Intended for charging radio control plane/heli/quad batteries at the flying field."
Model 1:
"240 individually fused cells, 4S60P, about 1.8kWh. JK BMS with Bluetooth connectivity for cell balance/protection/monitoring. About 13kg. 2x XT60 connectors. Can deliver about 40 amps comfortably @ 14.4v."
Model 2:
"160 individual cells, Not wired up yet. Will either be 4S40P or 8S20P at 1.2 kWh, JK BMS in transit. About 9kg, Single XT60 connector, will deliver 40 amps @14.4v or 20 amps @ 28.8v."
Model 3:
"72 cells recovered from Golf Buggy battery pack, left in original configuration of 4S9P and two of them placed in series to form 8S9P. BMS salvaged from a different 8S battery pack. Good for about 12 amps @ 28.8v"
