What our Experts Think

• Purpose-built 36V trolling system kit – The TMK-36V60-BT combines a 36V 60Ah LiFePO₄ battery system with integrated lithium-optimized charging, delivering a complete drop-in solution for high-demand trolling motors.
• Stable high-thrust performance – Designed to maintain consistent voltage under load, supporting strong continuous output for long trolling sessions without the voltage sag typical of lead-acid setups.
• Lead-acid replacement efficiency – Replaces multiple 12V batteries in series, significantly reducing system weight, wiring complexity, and onboard space requirements while improving usable capacity.
• High discharge capability for marine use – Built for demanding conditions with up to 100A continuous discharge and 500A peak bursts, ensuring reliable performance during sudden motor thrust demands.
• Smart Bluetooth BMS monitoring – Integrated battery management system enables real-time tracking of state of charge, temperature, and system health via mobile app for safer trip planning.
• Marine-grade durability – IP67-rated sealed construction and vibration-resistant casing designed for saltwater exposure, harsh weather, and offshore fishing environments.
• Long-cycle lithium advantage – Engineered for thousands of charge cycles with high energy efficiency, reducing lifetime cost compared to AGM or flooded battery banks.

Maintenance Tips

• Use only a 43.2V–43.8V LiFePO4-compatible charger (never lead-acid mode)
• Avoid deep discharge below ~30V cutoff voltage to protect the BMS
• Keep operating charge range between 0°C to 55°C for safe charging
• Store at 40–60% charge in cool, dry conditions (-5°C to 45°C)
• Recharge after each trip to maximize 3000–6000 cycle life
• Do not leave battery at 100% charge for long storage periods
• Keep terminals tight, clean, and corrosion-free (marine salt protection is critical)
• Use Bluetooth app to monitor voltage, temperature, and SOC health
• Avoid exceeding 100A continuous discharge limit
• Ensure proper ventilation in boat compartment during heavy trolling load
• Protect from shock, vibration, and water exposure (IP67-rated, but not abuse-proof)
• Do not open or modify the internal BMS system
• Disconnect during long storage to prevent parasitic drain
• Allow battery to warm before heavy load use in cold conditions (built-in heating support available on some variants)
