What Amp Should I Charge My 2s Lipo. 6 cell LiPo 252V max. Lipos do not like full charge or less than 40 or so.

This means that you charge them at 1 amp per amp-hour of capacity. 6 cell LiPo 252V max. This means that if you have a 200 mAh pack then it should be charged at a current of 20 Amps or 2000 mA.
I wouldnt recommend charging at higher rates without first verifying from the manufacturer what the max charge rating is.
Insert the balance plug into the port on the charging unit and wait for a reading. User should Always set the charger to the proper cell count andor voltage listed on Batteries labels. LiPo 22000 12S 444v Battery Pack. So one amp with your charger You can charge at higher current but it can be really bad for the batteries and they wont last nearly as long.
