A: Compatible with major 24V trolling motors including Minn Kota, MotorGuide, Garmin Force, Lowrance Ghost, Rhodan, and Power-Pole systems.

Maintenance Tips

• Use correct charger: Only charge with a LiFePO₄ charger set to 28.4–28.8V max. Avoid AGM/lead-acid modes to prevent imbalance or BMS stress.
• Avoid deep discharge: Recharge before 20–30% SOC to maximize lifespan (typically 3000+ cycles at full depth of discharge).
• Respect load limits: Keep continuous draw within 100A BMS rating to prevent cutoff during high-thrust or windy conditions.
• Temperature management:
• Charge: 0°C to 55°C
• Discharge: −20°C to 60°C
  Avoid charging below freezing unless battery heating system is active.
• Bluetooth monitoring: Regularly check voltage, current, temperature, and SOC to detect abnormal motor draw or wiring issues early.
• Marine protection: IP67 sealed, but still rinse salt/dust buildup and keep terminals dry to prevent resistance and heat buildup.
• Terminal care: Inspect M8 connections for tightness—loose lugs can cause voltage drop under trolling load.
• Storage best practice: Store at 50–70% charge in a cool, dry environment for long idle periods.
• Parallel use caution: Only connect batteries at equal SOC/voltage to avoid imbalance stress on the BMS.
• Regular use recommended: Periodic cycling helps maintain cell balance and accurate Bluetooth SOC calibration.
