BX100 1-8S LiPo Battery Voltage Tester and Low Voltage Buzzer

The BX100 is a pocket cell checker and low-voltage alarm in one. Plug a 1–8S pack's balance lead into it to read every cell and the total pack voltage, or leave it connected on the model as a loud warning when any cell drops below the threshold you set.

Key features

• Shows each cell voltage in turn, then the total pack voltage, on an LED display
• Alarm threshold adjustable from 2.7 V to 3.8 V per cell in 0.1 V steps using the mode button
• Twin piezo buzzers for an alarm you can hear at a distance
• Reads to ±0.01 V across a 0.5–36 V total-voltage range
• Works with LiPo, LiFe, Li-ion and LiMn packs; the alarm covers 2S–8S

Specifications

• Cell count: 1–8S (alarm mode 2–8S)
• Battery types: LiPo, LiFe, Li-ion, LiMn
• Measurement precision: ±0.01 V
• Total voltage display range: 0.5–36 V
• Alarm range: 2.7–3.8 V per cell, 0.1 V steps
• Alarm: dual piezo buzzer
• Display: LED digital

Use it to check packs before a flight, after charging, or to confirm storage voltage before putting LiPos away. Check the plug orientation before pressing the balance lead on: the black wire goes to the tester's negative side.
