Digital battery monitor for state-of-charge, voltage and hour tracking
The Runleader RL-BI025 is a versatile instrument for monitoring the health of 12-48 V lead-acid, lithium and GEL batteries. It displays the remaining capacity using a ten-LED bar and percentage value while also tracking total operating hours (TOT) and service intervals (SVC). Programmable voltage alarms and selectable discharge curves ensure accurate readings for different battery types. A backlit display and IP65 rating make it suitable for harsh environments.
🔧 Technical Highlights
- Applicable systems: 12 V, 24 V, 36 V or 48 V battery packs (DC) with selectable discharge curves for lead-acid, LiFePO4, GEL and AGM batteries.
- Display: ten-segment LED fuel gauge with numeric percentage and digital voltage readout; backlight with off/auto/on modes.
- Timers: total operating hours (TOT) counter ranges 0-999.99 hours; service interval (SVC) timer ranges 0-2000 hours with reset function.
- Voltage monitoring: measures real-time battery voltage and provides high and low voltage alarms.
- Installation: panel mounting (61 mm cut-out) with U-shaped bracket and 8-pin connector; IP65 water resistance.
✅ Benefits
- Shows remaining battery power and voltage at a glance to prevent unexpected shutdowns.
- Tracks machine run-time and schedules maintenance intervals for improved reliability.
- Supports multiple battery chemistries and voltage systems with user-selectable curves.
- Water-resistant housing and backlit display suit outdoor and mobile equipment.
🚀 Applications
- Golf carts, forklifts and industrial vehicles using 12-48 V batteries.
- Marine and recreational vehicles such as motorhomes and boats.
- Floor scrubbers, pallet jacks and other battery-powered industrial equipment.
The RL-BI025 helps operators monitor battery condition, log usage and plan service, making it ideal for a broad range of DC-powered machinery.
FAQs
- Q: How do the TOT and SVC timers work?
A: The TOT counter accumulates total running time up to 999.99 hours, while the SVC timer can be set between 0 and 2000 hours to remind you of maintenance.
- Q: Can I use the RL-BI025 with lithium batteries?
A: Yes. It supports various battery types including lead-acid, AGM, GEL and LiFePO4 by selecting the appropriate discharge curve.
- Q: What is the water resistance rating?
A: The monitor is IP65-rated, meaning it is protected against dust and low-pressure water jets, but should not be submerged.
