Product description： When the voltage of the battery pack or the voltage of a single battery is less than the set voltage lower limit, or the set discharge duration or set discharge capacity has been reached during discharge, the tester will automatically stop discharging and record the discharge Real-time data of all valuable and continuous processes in the process. Battery charge and discharge tester Technical index： Applicable battery Lead-acid battery Model DC220V Discharge current 0-100A recharging current 0-30A Operating mode Used independently or with a constant-current module Control accuracy Discharge current: ≤±1%; battery pack’s terminal voltage: ≤ ±0.1%; single battery voltage: ≤±0.05% Communication with the host PC RS485 interface Data storage capacity 2Gbit FLASH 20
