LiTech 12V 100A Lithium Battery  – Deep Cycle Power You Can Rely On

Looking for a reliable 12V 100Ah lithium battery that delivers exceptional performance, long cycle life, and unbeatable value? We designed our 12V 100Ah LiFePO4 battery to be a strong and safe deep cycle battery. It works well for many uses, including solar systems, RVs, boats, and trolling motors.

If you need a 12V 100Ah lithium trolling motor battery, this is a good option. It can also replace a 12V AGM battery of the same size. It also works well if you are comparing 12V 100Ah and 48V 100Ah systems. This battery will meet your energy needs with confidence.

✅ Key Features

• True 100Ah Capacity at 12.8V — equal to 1280Wh of usable energy
• Built-in Smart BMS (Battery Management System) protects against overcharge, over-discharge, overcurrent, and short circuit
• Lightweight (~11.5kg) – 50% lighter than a traditional AGM 12V 100Ah battery
• Ultra-safe lithium iron phosphate (LiFePO4) chemistry
• Long lifespan: 4000–6000 cycles @ 80% DOD
• Fast charging and low self-discharge
• Maintenance-free, no acid or ventilation required

⚙️ Series and Parallel Connections for 12V 100Ah Batteries

If one 12v 100ah battery is not enough, you can connect multiple units either in series or parallel to increase voltage or capacity.

🔼 Series Connection: Increase Voltage

Connecting batteries in series increases the voltage while keeping the capacity (Ah) the same.

• 2× 12V 100Ah batteries in series = 24V 100Ah
• 4× 12V 100Ah batteries in series = 48V 100Ah

This is ideal for higher-voltage systems like:

• Inverters for solar storage
• Electric vehicles
• 24V/48V trolling motors
• (Use in place of 12v 100ah vs 48volt 100ah setups)

Note: Always use batteries of the same model and age for safety and consistency.

➕ Parallel Connection: Increase Capacity

Connecting batteries in parallel keeps the voltage the same but increases capacity (Ah).

• 2× 12V 100Ah = 12V 200Ah
• 4× 12V 100Ah = 12V 400Ah

This setup is perfect for:

• Longer runtime in RVs or campers
• Solar energy storage with large daily loads
• Backup power systems

✅ Tip: Yes, 2 AWG wire is OK for connecting 12V 100Ah batteries in parallel, depending on your current draw.

🌍 Applications

• ✅ RVs, Camper Vans, and Caravans
• ✅ Off-grid Solar Systems (as a 12V 100Ah solar battery)
• ✅ Marine and Trolling Motor Use – one of the best 12V 100Ah lithium batteries for trolling motor setups
• ✅ Energy Backup Systems and UPS
• ✅ Mobility scooters, Golf carts, and Electric boats
• ✅ Off-grid cabins and Tiny homes

This battery is a direct replacement for a lead-acid or 12V AGM battery with 100Ah. It offers more energy density and a longer cycle life. Also compatible with major brands like Power Queen 12V 100Ah, Siekon 12V 100Ah, Litime 12V 100Ah, and Li Time 12V 100Ah.

🔌 Installation Tips

For safe, high-current use, 2AWG wire is good for connecting 12V 100Ah batteries. This is true when running continuous loads or making parallel or series battery banks. You can connect up to 4 batteries in a series for a 48V 100Ah lithium battery setup. You can also connect multiple batteries in parallel to increase capacity.
