CAMWAY 5PCS 2in1 1-8s Lipo Battery Voltage Tester, RC Low Voltage Buzzer Alarm
Quick take
CAMWAY’s 5-pack LiPo battery voltage testers let RC pilots check cell voltages and total voltage, with an adjustable low-voltage buzzer alarm. They are best for people who regularly monitor 1S to 8S LiPo, Li-ion, LiMn, or Li-Fe packs and want a fast, portable way to spot low-voltage risk before it causes problems.
The main caveat is that the audible alarm can be loud, and getting reliable readings depends on using the correct battery tap connection method for your pack.
Pros and cons
Pros
- LED voltage display shows per-cell voltages, total voltage, lowest cell voltage, and low-voltage status.
- Low-voltage buzzer alarm includes a default preset threshold (3.3V) and allows changing the alarm setting.
- Comes as a 5-pack, so you can keep testers in multiple places (bag, charger area, vehicle).
- Designed for 1-8S LiPo, Li-ion, LiMn, and Li-Fe battery types commonly used in RC.
Cons
- Low-voltage warning sound is reported as quite loud, which can be annoying in quiet settings.
- Standalone use and nonstandard connector wiring may lead to erratic results, since accurate reads require the intended tap connections.
What buyers think
Buyer-review evidence is strongly consistent on practicality: the devices are described as small, easy to use, and handy to keep around for routine voltage checks. Multiple comments highlight that the buzzer alarm is noticeably loud and does its job when a pack drops below the set threshold. Reviewers also emphasize the value of having several testers for different locations, rather than needing to pull one device out every time.
At the same time, feedback on accuracy and behavior when used outside the intended connection approach is limited. Overall, the recurring themes point to ease of monitoring when used as intended, and a reminder that connector compatibility matters.
What this tester does (and why RC pilots use it)
This CAMWAY tester is built for quickly checking the health of lithium packs by reading voltage. Rather than only showing a total pack voltage, it focuses on lithium cell monitoring, which is important because one weak cell can drag down overall pack performance and increase risk if it is pushed too far.
It provides an LED voltage display that can show:
- Cell voltages (with the device progressing through cells for 1-8S packs)
- Total voltage
- Lowest cell voltage
- Remaining battery capacity information (as indicated by the monitor’s display mode)
It also includes a low-voltage alarm mode. When the voltage goes below the set threshold, the tester keeps buzzing and lights a red LED, helping you avoid over-discharging your packs.
Key features that matter for buying
1 to 8S compatibility for common RC battery chemistries
The tester is intended for 1-8S LiPo, Li-ion, LiMn, and Li-Fe batteries. If you run mixed pack sizes across a fleet of drones, planes, or cars, that range coverage is a practical advantage.
Adjustable low-voltage threshold
The default low-voltage alarm setting is 3.3V, and there is a push-button control to change the alarm voltage setting and save it. That matters because different setups and usage patterns can call for different cutoff behavior.
LED readout for quick, field-friendly checks
Because it uses an LED voltage display, it is designed for quick glances rather than a slow, menu-heavy interface. This is the kind of tool you want near your charger, in your battery bag, or in your vehicle.
Pros and cons for typical shoppers
Who it’s best for
- RC pilots who want a compact way to check cell voltages before charging or flying/driving.
- People managing multiple batteries and locations who value the included 5-pack (dedicated tester per bag, charger shelf, or field kit).
- Buyers who prefer an audible low-voltage alert and are okay with adjusting the alarm threshold.
Who should avoid (or think twice)
- Shoppers who plan to use it with nonstandard connector wiring or as a “generic” voltage reader in setups it was not designed for, since reliable readings depend on correct tap connections.
- Anyone who is sensitive to loud warning sounds, because the buzzer is consistently described as quite loud.
Setup and usage tips to get reliable readings
- Confirm you are using the intended battery tap connection method for your specific pack style and cell count (1S through 8S).
- Set the low-voltage alarm threshold intentionally, using the device’s push-button control, rather than leaving everything at the default if your packs are managed differently.
- Use it as part of a regular routine, such as checking before charging and after sessions, so you catch imbalances early.
Value: is it worth the buy?
For shoppers who regularly run 1-8S lithium packs, the value proposition is the combination of quick cell-level voltage reading, an adjustable low-voltage buzzer alarm, and the convenience of owning multiple testers. If you only need occasional total voltage checks, you might not need a cell-focused monitor. But if you want to reduce the chance of running a pack too low or missing a weak cell, this category of device can be a practical day-to-day tool.
Because connector compatibility can affect performance, it is worth making sure your battery type and how you plan to connect it match the tester’s intended use. If you do, the reviews suggest it will feel like a straightforward, reliable way to monitor packs in the field.

FAQ
Is this tester only for LiPo batteries?No. It is intended for 1-8S LiPo, Li-ion, LiMn, and Li-Fe batteries, making it useful for several common lithium chemistries used in RC.
Does it show individual cell voltage or just total pack voltage?It is designed to display cell voltages, along with total voltage and the lowest cell voltage.
How loud is the low-voltage alarm?The alarm buzzer is reported as quite loud. If you find loud alarms disruptive, that is an important consideration before buying.
Can I use it with any connector or charger setup?Reliable readings depend on using the intended tap connections for your battery setup. Using it outside its intended connection style can lead to erratic results.
What is the default low-voltage threshold?The default preset alarm value is 3.3V, and you can change it using the push button.
