LiTime 36V 50Ah Bluetooth Lithium Battery
The LiTime 36V 50Ah Bluetooth Lithium Battery is a 38.4V LiFePO4 battery rated for 1920Wh of energy, built for 100 to 120 lb thrust trolling motors. It's housed in a Group 31-sized case measuring 13" L x 6.77" W x 8.5" H and weighs 33.14 lbs (15 kg), about 65% lighter than three 12V 50Ah lead-acid batteries wired together to the same voltage.
The 50A BMS supports 50A of continuous discharge and charge, with a surge rating of 250A for 1 second and internal resistance of 40 mΩ or less. It includes over 20 protections, among them a pre-charge function, over-current protection with auto-recovery, and short-circuit protection. The IP65-rated housing handles water and dust resistance, and low-temperature protection stops charging below 32°F (0°C) and discharging below -4°F (-20°C), resuming above 41°F (5°C).
Bluetooth 5.0 connects to the LiTime app for monitoring of state of charge, charge/discharge status, voltage, current, power, temperature, and lifecycle data, with remote discharge control and power-off. It's rated for 4,000 cycles at 100% depth of discharge, 6,000 at 80% DOD, and 15,000 at 60% DOD, with an expected service life of over 10 years and a 5-year warranty. Up to four batteries can be wired in parallel for a 36V 200Ah bank.

LiTime 36V 50Ah Battery FAQs
What is the LiTime 36V 50Ah Battery built for?
This is a 38.4V, 1920Wh LiFePO4 battery sized for 100 to 120 lb thrust trolling motors, the larger end of the trolling motor range. It's built into a single Group 31-sized case rather than requiring multiple 12V batteries wired in series.
How much current can the LiTime 36V 50Ah Battery deliver?
The BMS supports 50A of continuous discharge and charge, with a surge rating of 250A for 1 second. Size your trolling motor and wiring to the 50A continuous rating, since the surge figure is a brief spike rather than sustained output.
Does the LiTime 36V 50Ah Battery have cold-weather protection?
Charging automatically stops below 32°F (0°C) and discharging stops below -4°F (-20°C), resuming once the battery warms back above 41°F (5°C). This model does not include a self-heating function.
Can I wire multiple LiTime 36V 50Ah Batteries together?
Yes, up to four batteries can be wired in parallel for a 36V 200Ah system. LiTime's page for this battery does not document a series (voltage-stacking) configuration beyond the 36V it ships at.
What warranty covers the LiTime 36V 50Ah Battery?
LiTime backs this battery with a 5-year warranty and rates its expected service life at over 10 years. LiTime's product page does not publish the full written terms, coverage exclusions, or claims process, so we can't state those specifics here. Contact us and we'll get you the exact terms before you buy if that's a deciding factor.
