• 18650 Battery Tester can be used with 21700 battery holders. Measurement of 21700 batteriesFeatures
  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.

  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.
  External test: support, can be discharged through the 2P terminal external, a single channel single time only and can only support the battery holder or external test in one, can not be used at the same time the battery holder and external battery test.
  Battery reverse connection protection: reverse connection protection, prohibit reverse connection of the battery.
