What Are the Key Features of the LiTime 12V 100Ah TM Battery?
This battery includes a lithium iron phosphate (LiFePO4) chemistry, 1280Wh capacity, and a 100A continuous discharge rate. It weighs only 24.2 lbs—33% lighter than lead-acid alternatives. The IP65 waterproof rating and vibration-resistant construction ensure durability in harsh marine environments. Integrated BMS protects against overcharge, over-discharge, and short circuits.
How Does It Compare to Lead-Acid Trolling Motor Batteries?
Unlike lead-acid batteries, the LiTime TM provides 95% usable capacity (vs. 50% in lead-acid), faster charging (4 hours with a 20A charger), and zero maintenance. It operates efficiently in temperatures from -4°F to 140°F and retains 80% capacity after 2,000 cycles, outperforming AGM/gel batteries that typically fail after 500 cycles.

Marine enthusiasts will appreciate the immediate voltage consistency during extended use. While lead-acid batteries experience voltage sag under load, the LiTime maintains stable output even below 20% charge. This translates to consistent trolling motor performance throughout your fishing expedition. The weight advantage becomes critical when calculating boat payload – swapping three 35lb lead-acid batteries for a single 24lb LiTime unit saves 81lbs, allowing for additional gear or fuel capacity.

What Safety Mechanisms Are Built Into the Battery?
The multi-layered BMS prevents overvoltage, undervoltage, overcurrent, and cell imbalance. Its flame-retardant casing and thermal runaway protection mitigate fire risks. Paralleling capability allows connecting up to four units without voltage drop, while the self-discharge rate is less than 3% per month—ideal for seasonal storage.
Advanced safety protocols include cell-level temperature monitoring that triggers automatic shutdown at 167°F. The compression-resistant ABS casing withstands 500psi impacts, crucial for offshore use. Unlike some lithium batteries, the LiTime TM uses military-grade terminal connectors resistant to saltwater corrosion. Field tests show the BMS successfully interrupts 150A short circuits within 0.1 seconds – 3x faster than industry standards.
Which Trolling Motors Are Compatible With This Battery?
It works with 12V motors from Minn Kota (Terrova, PowerDrive), MotorGuide (Xi5, X5), and Haswing. The stable 12.8V output supports thrust requirements up to 55 lbs. Users report 8-10 hours of runtime at medium speed (30-40% throttle) on 18-22ft boats.
How Should You Maintain the LiTime TM Battery for Optimal Lifespan?
Store at 50% charge in temperatures between -22°F to 113°F. Use a lithium-specific charger to avoid sulfation. Clean terminals quarterly with dielectric grease. Recalibrate the BMS every 50 cycles by fully discharging/charging. Avoid submerging beyond IP65 limits.
What Environmental Benefits Does This Lithium Battery Offer?
LiFePO4 chemistry contains no toxic lead or acid, reducing landfill hazards. Its 10-year lifespan decreases replacement frequency, cutting resource consumption. The 98% energy efficiency minimizes fossil fuel use in charging compared to 70-85% efficiency in lead-acid systems.
Expert Views
“The LiTime TM series represents a paradigm shift in marine energy storage. Its pulse discharge capability (200A for 5 seconds) handles sudden thrust demands that traditionally required dual lead-acid batteries. For charter operators, the 2-hour recharge time between trips is game-changing.” — Marine Power Systems Analyst
FAQs
- Can This Battery Power Other Marine Electronics?
- Yes, it can simultaneously run fishfinders, livewell pumps, and LED lighting via a marine distribution block, provided total draw stays under 100A.
- Does It Require a Special Charger?
- Use a LiFePO4-compatible charger with 14.6V absorption voltage. Standard lead-acid chargers may undercharge the battery, reducing capacity.
- What Warranty Coverage Exists?
- LiTime offers a 5-year limited warranty, prorated after year two. Registration within 30 days of purchase extends support to 66 months.
