Features: 1. The blue segment at the upper end is the external discharge terminal, and the lower end has the working indicator of the corresponding channel. 2.Voltage and current curve display, real-time voltage and current, DC two-wire method to measure internal resistance. 3. U-shaped groove at the back is combined with PCB board, and the fan actively dissipates heat to form a heat dissipation channel. 4.18650 battery holder using compact battery holder, suitable for flat battery measurement. 5. Channel type: 8 independent channels, each unrelated, independent operation, without mutual influence. 6.Channel synchronisation: support 8 channels to set up synchronisation, also can set up each channel parameter individually. 7. Cycle charging and discharging: only support charging-discharging-charging 1 cycle in automatic mode, do not support multiple cycles. Parameter: Working voltage: DC5V 10A (standard bare metal, without power supply), overpressure must burn machine Power supply interface: ①: DC5.5 high-current interface, ②: 5V positive and negative welding points Power supply reverse protection: reverse protection, prohibit reverse power supply ①Automatic mode: program start ~ 4.2V charging stop voltage for charging, charging current is less than the stop current for 30 seconds, the first charging is completed ~ quiescent (not charging and not discharging) ~ discharge according to the stop voltage setting, the load voltage is lower than the stop voltage for 10 seconds, discharging is completed ~ quiescent (not charging and not discharging) ~ charging with the re-charging voltage as the stop voltage, re-charging voltage is set to 4.2V, charging current is less than the stop current for 30 seconds, the program is set to stop voltage. When the recharge voltage is set to 4.2V, the charging current is less than the stopping current for 30 seconds, the programme ends (when the recharge voltage is not equal to 4.2V, the battery voltage reaches the recharge voltage, the programme ends), the recharging is completed, the programme ends, and the operation of the automatic mode is completed. ②Charging mode: program start ~ charging voltage is set to 4.2V, charging current is less than the stop current for 30 seconds, the programme ends (charging voltage is not equal to 4.2V, the battery voltage reaches the charging voltage, the programme ends) ~ charging is complete. ③ Discharge mode: programme start ~ load voltage lower than the stop voltage for 10 seconds, programme end ~ discharge complete ④Activation mode: only for professional use, during the use, the tester shall not leave the field! Forced charging with charging stop voltage, it will not stop automatically, need to end manually. Charging current: each channel independently maximum about 1A, and charging current is not adjustable. Charging stop voltage: 3.7V, 3.8V, 3.9V, 4.0V, 4.1V, 4.2V total of 6 adjustable steps Recharge stop voltage: 3.0V, 3.1V, 3.2V, 3.3V, 3.4V, 3.5V, 3.6V, 3.7V, 3.8V, 3.9V, 4.0V, 4.1V, 4.2V adjustable in 13 steps. End current: 100mA, 200mA, 300mA adjustable. Discharge current: each channel independently maximum about 1A non-constant current discharge, and discharge current is not adjustable. Discharge stop voltage: 2.0V, 2.1V, 2.2V, 2.3V, 2.4V, 2.5V, 2.6V, 2.7V, 2.8V, 2.9V, 3.0V, 3.1V, 3.2V, 3.3V, 3.4V, 3.5V, 3.6V, total 17 adjustable. Standing time: 1~5 minutes adjustable. Status preview: support 8-channel status preview on 1 screen Single-channel detail display: support Single-channel charging and discharging curve display: support Internal resistance detection: DC two-wire method, only for the same batch sorting analogy Heat dissipation mode: active heat dissipation Overheating protection: Support Cyclic charging and discharging: only 1 cycle of charging-discharging-charging is supported in automatic mode, multiple cycles are not supported.
