YEA-W52-BATT - W52H Battery

got a rigid battery 24 volt 3 ampere hour built in 2006 so that's 10 years old undid the torque security you have to slip this to get this apart here's the case now I've got the battery pack it's got four giant lithium's here and they're bigger than the 18 650s they're much bigger in diameter there's six of them in series and I'm running this through a power supply I was running this little amp power design one only puts a half amp founded starting put some charge on it I got 23 volts across the all six cells right now I'm using a LAN tech power supply 120 volts three amps of switcher from China putting three amps in got a fire extinguisher right by because this is kind of a hokey setup but when I first measured the cross each cell it was only about pulling o 1 volt so they're all basically dead and it connected up this charger and just put a little charge a little voltage across about
