Overview

Lithium Pros 36 V Lithium-Ion Bluetooth Marine Trolling Batteries

Lithium Pros 36 V lithium-ion Bluetooth marine trolling batteries are high-performance LiFePO4 batteries designed to replace three traditional Group 31 AGM 12V batteries with a single unit. Engineered for 36-volt trolling motors, they offer significant weight savings (up to 170+ lbs.), faster recharge times, and consistent power delivery throughout the day.

Key features and advantages:

* Performance—these batteries maintain a higher voltage under load compared to lead-acid, providing sustained trolling motor power from dawn to dusk
Bluetooth Monitoring—the TM series includes integrated Bluetooth connectivity, allowing users to monitor real-time data—such as voltage, amperage, state of charge (SoC), and time remaining—via the "LP Battery View" app
* Weight and Space Saving—replacing three 12V AGM batteries with one 36V Lithium Pros battery (often weighing under 45 lbs.) can reduce boat weight, allowing for faster speeds and better fuel efficiency
* Capacity Options—common configurations include 36V 65Ah (TM3165-36) with 155 reserve minutes and 36V 67Ah (M3167-36) with 160+ reserve minutes
* Safety and Durability—they feature an internal Battery Management System (BMS) for automatic cell balancing, over-temperature protection, over/under voltage protection, and short circuit protection
* Construction—the batteries are IP67 water-resistant and designed to fit in a standard Group 31 battery tray
* Cold Weather Protection—certain models (e.g., M3167-36) include an internal heating system, allowing for proper charging in temperatures as low as -4 degrees F

Notes and Limitations: These batteries are not intended for engine starting or charging from an outboard alternator. A 38.4V (or 36V nominal) LiFePO4 compatible charger is required. Typical AGM chargers may not fully charge them or may damage them depending on settings.
