The SunGold Power 12V 100AH LiFePO4 Deep Cycle Lithium Battery Brings Self-Heating, Bluetooth Monitoring, and IP65 Protection to 12 Volt Systems
The SunGold Power 12V 100AH LiFePO4 Deep Cycle Lithium Battery stores 1280 watt-hours of energy in a lightweight 22.7 pound case. It uses lithium iron phosphate chemistry with a built-in 100A battery management system, and SunGold rates it for 4000 or more cycles at 80 percent depth of discharge.
It is built for RVs, caravans, boats, and solar systems. A self-heating function protects it when charging in cold weather, an LCD display and Bluetooth app show state of charge and battery data, and an IP65-rated case resists dust and water. You can choose 1, 2, or 3 batteries using the options on this page.
SunGold Power 12V 100AH LiFePO4 Deep Cycle Lithium Battery Features
4000+ Cycle LiFePO4 Chemistry
Lithium iron phosphate is one of the most stable lithium chemistries for deep cycle use. SunGold rates this battery for at least 4000 cycles at 80 percent depth of discharge and more than 10 years of service life, with 99.5 percent or higher efficiency.
Automatic Self-Heating for Cold Weather Charging
When the battery's core temperature drops below 33.8°F (1°C), the self-heating function turns on automatically, and it shuts off once the battery reaches 42.8°F (6°C). The battery can charge from -4°F to 113°F and discharge from -4°F to 131°F.
Bluetooth App and LCD Display
Press the button on the built-in LCD to see voltage and state of charge, or use the SGP Battery app for iOS and Android to monitor battery and cell data over Bluetooth.
Built-In 100A BMS
The battery management system supports up to 100A of continuous charge current and 200A peak discharge for 15 seconds, with 50A recommended for regular charge and discharge. It protects the cells and balances them automatically.
IP65 Case and Easy Expansion
The ABS case is IP65 rated. Batteries can be connected in parallel for more capacity or in series for 24V or 48V systems, with up to four batteries in series (a maximum of 58.4V).
Real-World Applications
RVs and caravans. Replace heavy lead acid house batteries with a lighter battery that delivers more usable energy.
Marine house banks. Power electronics, lights, and appliances on board with an IP65 case.
Small solar systems. Store solar energy for cabins, sheds, and remote equipment.
Cold climate use. Self-heating supports charging in freezing conditions.
How It Compares to Common Alternatives
Versus AGM and lead acid batteries. LiFePO4 offers far more cycles, lower weight, and deeper usable discharge.
Versus the 12V 200Ah model. The 200Ah version doubles the energy to 2560Wh in a single case with a 200A BMS. The 100Ah model is easier to fit and carry.
Versus batteries without heating. Standard lithium batteries should not be charged below freezing. This model heats itself before charging in the cold.
Is This Battery the Right Fit
-
System voltage. 12V nominal (12.8V), or wire in series for 24V or 48V.
-
Charging. Use a LiFePO4-compatible charger. SunGold recommends 14.4V to 14.6V at 0.2C to 0.5C.
-
Space. 12 x 6.6 x 8.9 inches and 22.7 pounds per battery.
-
Bank size. SunGold allows up to four batteries in parallel or four in series.
This may be a good fit if
- You want a lighter replacement for lead acid batteries
- You charge in cold weather
- You want Bluetooth battery monitoring
- You need an IP65-rated case
Common Questions
How Long Will This Battery Last?
SunGold rates it for 4000 or more cycles and estimates 5 to 10 years of life depending on use, with a 5 year warranty.
How Many Batteries Can Be Connected Together?
Up to four in parallel or four in series.
Can I Mix It With Other Batteries?
SunGold advises against mixing manufacturers, types, or new and old batteries. Fully charge each battery separately before connecting them.
How Should I Store It?
Store at about half charge in a cool, dry place and charge and discharge it every three months.
