Frienda 2 Set DC 12V 24V 36V 48V 60V 72V 84V Golf Cart Battery Meter with Alarm
Quick take
The Frienda 2 Set battery meter is a pair of LCD gauges that show both voltage and battery capacity percentage, plus a low-battery alarm that flashes under 20%. It’s designed for a wide range of DC systems from 12V up to 84V and supports multiple battery types, making it attractive for golf carts and other battery-powered equipment. The main caveat is that configuration can be more complex than “true plug-and-play,” so double-check battery-type and settings behavior before you install.
Pros and cons
Pros
- Large voltage range support (12V through 84V) for different battery pack setups.
- Shows battery capacity percentage and real-time voltage on a backlit LCD for easier monitoring.
- Low-battery alarm flashes when capacity drops below 20%.
- Backlight and sleep mode support help manage display visibility and power use.
Cons
- Buyer feedback suggests display parameter changes and battery-type settings may take extra time to figure out.
- Some buyers note the display is less precise than they expected (for example, limited decimal detail), which may limit “fine-grain” measurement.
- Review evidence includes at least one case of incorrect readings when the meter was used for a 36V golf cart, so correct setup matters.
What buyers think
Buyer-review evidence is mixed but reveals a few clear themes. Several buyers liked the bright, readable LCD and found installation straightforward once they understood the setup steps. Others reported that the meters do work as indicated for simple voltage and capacity monitoring use cases, including hobby battery packs. At the same time, some buyers found the settings process cumbersome, mentioning that changing display parameters required careful button sequencing and that instructions were not always complete. One low-rating review claims the device showed a constant 100% value and gave voltage readings they considered far off for a 36V golf cart, highlighting that correct programming and battery compatibility are important.
How this battery meter works for real-world monitoring
This is a DC battery capacity and voltage indicator set. The LCD can switch between showing battery capacity percentage, voltage, or cycling the display. There is also a low-battery alarm feature, designed to flash when the measured capacity falls below 20%, which can help you avoid running your pack down unintentionally.
The front design includes a switched function button and a separate setting button used to select battery specifications and control behavior (for example, sleep mode and backlight). The goal is to give you quick status at a glance, not deep diagnostic analysis.
Battery and voltage compatibility (what to match before buying)
These meters are marketed for a wide span of DC systems: 12V, 24V, 36V, 48V, 60V, 72V, and 84V. They are also intended to work with multiple battery chemistries, including acid batteries as well as lithium-ion related battery types (such as ternary lithium and polymer lithium-ion). They’re also described as suitable for battery pack structures like 3 to 15 series lithium-ion configurations.
Buy-sanity check: before installing, confirm your pack’s nominal voltage and your battery chemistry (and series configuration for lithium-ion). If your settings do not match your battery type, the capacity percentage display can be misleading, even if the unit is physically connected correctly.
Pros and cons that matter for buyers
Brightness and readability
The LCD is designed with a bright backlight, and the display is stated to be readable from different angles. In reviews, buyers who installed these for battery monitoring repeatedly mention the screen is easy to read.
Alarm behavior and “when should I recharge?”
The alarm is tied to capacity level, flashing below 20%. That can be helpful for routines like charging golf cart packs after a predictable usage threshold. However, remember this threshold depends on the meter’s capacity calculation, which itself depends on correct battery settings.
Setup complexity versus plug-and-play expectations
One of the most important practical considerations is configuration. While some buyers describe setup as straightforward, others report that changing display parameters took time and required keeping the settings button pressed in a particular way. This suggests that if you want instant, no-thinking operation, you may need patience during the first install.
Water protection and durability
The gauge includes a waterproof screen protector and is housed in an industrial-grade ABS protective shell. The low power consumption claim (up to 5 mA mentioned) and sleep mode are aimed at reducing unnecessary draw when you are not actively checking the display.
Verdict: is the Frienda 2 Set worth it?
The Frienda 2 Set makes sense if you want a simple, glanceable way to monitor both voltage and estimated capacity for DC battery systems across many voltage options, including golf cart-style setups. It’s a good fit for buyers who are comfortable spending a few minutes getting battery-type and settings correct, and who value a readable backlit display with a flashing low-capacity alarm.
It may be a poor fit for buyers who insist on true plug-and-play operation, or who need highly precise measurement readouts beyond what an indicator gauge with limited decimal detail can provide. If you are using a 36V (or any nontrivial) pack, be extra careful that your meter configuration matches your battery chemistry and system voltage, since misconfiguration can lead to incorrect readings.
Alternatives to consider (based on your needs)
If you want a similar outcome but with a different tradeoff, consider these comparison points rather than specific model names:
- If you prioritize accuracy over “percentage estimates”: look for meters that emphasize voltage-only readouts or provide clearer calibration guidance for your battery chemistry.
- If you prioritize ease of setup: choose indicators that offer simpler button controls, clearer wiring diagrams, or fewer configurable battery profiles.
- If you monitor frequently and outdoors: prioritize displays with strong IP/weather protection and mounts designed for your environment.
FAQs
How many meters come in the Frienda 2 Set?
It’s sold as a set of 2 meters (two units total).
Does it display both battery voltage and battery capacity percentage?
Yes. The LCD can switch between showing voltage and battery capacity percentage.
What triggers the alarm?
The alarm is designed to flash when battery capacity drops below 20%.
What battery voltages and chemistries is it compatible with?
It’s intended for DC systems from 12V up to 84V and is described as compatible with acid batteries and several lithium-ion battery types, including ternary lithium and polymer lithium-ion configurations.
Is it truly plug-and-play?
Some buyers find installation straightforward, but others report that changing settings and selecting battery parameters may require careful button sequencing. Expect some setup time, especially during the first configuration.
Will it work for a golf cart battery pack?
It is marketed for golf cart-style monitoring and supports common golf cart voltages (such as 36V). For best results, match the meter settings to your battery type and pack voltage.
