      Frequently Questions Answer

      1. Does this unit work with lithium batteries? Is there an adjustable curve for charge discharge voltages?

          Dear Customer, it's ok to work with lithium battery, LiFePO4 in types is for lithium battery, in addition, we are sorry to advise the charge and discharge voltage can't be adjusted, hope your kind understanding, thanks.
