Four small rectangular battery checkers with LCD screens and JST-XH balance ports on one side

AOICRIE 4-Pack Lipo Battery Checker 1S-8S +/-0.01V 1655

SKU CH-4M8B-BYPSF

A four-pack of voltage checkers that read individual cell and total pack voltage for 1S-8S lithium batteries with ±0.01V precision and an adjustable low-voltage buzzer alarm

  • FeaturesNist Traceable, Battery Powered
  • Sports Team2 Piece
  • TypeVoltmeter
  • Monitors each cell and total pack voltage with ±0.01 V precision
  • Audible buzzer and red LED warn you at adjustable 2.7–3.8 V thresholds
  • Works with 1S–8S LiPo, LiFe, LiMn and Li-ion packs using JST-XH balance leads
  • Reverse-polarity protection prevents damage if the connector is inserted backwards
  • Four checkers in one pack let you test multiple batteries at once

4-Pack Lipo Battery Checker 1S-8S

This four-pack supplies voltage checkers for 1S to 8S lithium packs. Each unit reads individual cell voltages and total pack voltage with a precision of +/-0.01V. The tool suits RC pilots and builders who need to monitor multiple battery packs at the field or bench.

Suits multi-pack owners needing audible alerts

The built-in buzzer and red LED warn when any cell drops below the set threshold, adjustable from 2.7V to 3.8V per cell in 0.1V steps. Users who only fly large packs above 8S or who require wireless telemetry logging should look at a different class of monitor.

Plug-and-play with JST-XH balance leads

Insert the balance plug with the white lead aligned to the leftmost pin at 0.12 inch spacing; the display powers instantly and cycles through cell data. Reverse-connection protection prevents damage if the plug is inserted backwards. The only common issue is forgetting to press the button to save a new alarm threshold after adjustment.

Questions about this item

Do I need to provide my own power source for the AOICRIE checker to operate?

No, the unit is battery powered and draws its supply directly from the balance lead of the 1S-8S pack you are testing.

Will the JST-XH balance plug on my older 3S LiPo pack fit the 3 mm pin spacing of this checker?

Yes, the checker uses a straight-pin JST-XH connector with approximately 0.12 inch spacing, which matches the standard balance lead found on 1-8S LiPo, LiFe, LiMn and Li-ion packs.

How can I verify the +/-0.01 V accuracy after I connect a pack?

The display cycles through individual cell voltages, total pack voltage, lowest cell voltage and remaining capacity; compare the shown cell values against a known-good reference meter to confirm the stated precision.
