2PCS Battery Capacity Voltage Meter

Safpovel’s twin LCD battery meters show real-time voltage and remaining capacity for DC 7–100V systems, with IP68 waterproofing and a low-voltage alarm to protect lithium and lead-acid packs.

Keep accurate tabs on your battery bank whether it’s in a golf cart, motorcycle, car, boat, or custom system. These two compact digital gauges offer bright blue-backlit displays, persistent memory of your settings, and ultra-low standby current so the monitors themselves don’t drain the battery. Built for broad compatibility, the meters support common 12V–84V battery standards and also include a custom-mode range for any DC system between 7 and 100 volts.

What batteries and voltages will this monitor work with?

The Safpovel meter is designed for multiple chemistries and nominal voltages, covering a wide selection of vehicles and stationary systems. It recognizes common lithium and lithium-iron series as well as traditional lead-acid banks and lets you set a custom voltage range if your pack falls outside preset values.

• Compatible with L03–L20 lithium and L04–L24 lithium-iron battery series.
• Works with DC 12V, 24V, 36V, 48V, 60V, 72V, 84V lead-acid systems.
• Custom mode supports any DC voltage from 7V up to 100V.
• Two-unit kit useful for monitoring two separate battery banks or backups.

How does the display and alarm help me avoid unexpected power loss?

The bright blue LCD shows both numeric voltage and a visual remaining-capacity readout so you can judge state of charge quickly at a glance. If the meter detects the capacity falling below the set threshold, an attention-grabbing low-voltage alarm flashes to prompt recharging before the cells reach critical depletion.

• Clear numeric voltage readout plus capacity percentage on one screen.
• Blue backlight for visibility in low light and daytime readability.
• Low-voltage flashing alarm triggers when capacity drops below 10% (configurable).
• Ideal for pre-trip checks on boats, carts, and motorcycles.

Does it save settings and consume a lot of power?

Safpovel built the meter to be energy-efficient and user-friendly: it remembers your configuration when power is removed and automatically restores those settings on restart. Normal operation draws under 15mA and it falls to less than 1mA in power-saving mode, so the monitor won’t be a significant parasitic drain on your battery bank.

• Automatic power-off memory preserves previous settings.
• Steady operation current below 15mA keeps standby losses low.
• Power-saving mode reduces consumption to under 1mA.
• Simple wiring and compact footprint for tight installations.

How rugged and easy to install is the meter for outdoor use?

The meter is built with an IP68-rated sealed acrylic cover to resist water and dust, making it suitable for exposed environments like boats and open carts. Its small form factor and straightforward wiring mean you can mount the display in consoles, dash panels, or near battery enclosures with minimal effort.

• IP68 waterproof acrylic cover protects the LCD and electronics.
• Compact panel-mount size fits common cutouts and dash spaces.
• Durable construction suits marine, automotive, and outdoor use.
• Includes two units for monitoring primary and auxiliary batteries.

Who this is for: Installers, fleet owners, and DIY vehicle or marine enthusiasts who need reliable, easy-to-read battery condition monitoring across a variety of battery chemistries and voltages. It’s especially useful for golf cart fleet managers, boat owners, motorcycle riders, and anyone with custom battery systems looking for an affordable, waterproof meter that preserves settings and minimizes its own power draw.
