Our Product Category

Portable Power Station Expansion / Extra Batteries

This category includes LFP expansion batteries designed to increase the capacity of supported portable power stations. Each unit connects through a plug-and-play interface and includes the necessary cable for quick setup. Some models feature a stackable structure for organized home or indoor backup use. These units function exclusively as add-on batteries for compatible systems, providing extended runtime for power-heavy or long-duration needs.

48V Golf Cart / Utility Vehicle Battery Pack

The 48V golf cart and utility vehicle power option delivers a LiFePO₄ traction battery built for carts, utility rigs, and 48V RV or van conversions that need a compact, high-endurance upgrade. The system offers around 1.63kWh of capacity with a GC2 form factor, making it a direct replacement for T-105 lead-acid packs while providing far stronger cycle life and efficiency. Users get practical features such as an LED capacity meter for quick status checks and CANBus support for more detailed communication with vehicle systems. An IP67 enclosure shields the battery from dust and water, and the onboard BMS adds protection along with a self-heating function that keeps performance stable in cold conditions. This setup gives drivers a durable, weather-ready solution made for demanding day-to-day cart and utility use.

Deep-Cycle LiFePO4 House Batteries 

RV and camper owners who need steady, day-to-day power for lights, appliances, and solar charging will find dependable options here from brands like BigBattery, ACOPower, and more. The lineup includes 12V, 24V, and 48V LiFePO₄ systems, with capacities reaching up to 5.12kWh for setups that require long runtimes and consistent performance on the road. BigBattery’s HUSKY series provides higher-capacity solutions ideal for full-time RV or van conversions, while ACOPower’s 12V models are well-suited for smaller electrical systems or mixed RV-and-solar use. Each battery is built for deep-cycle reliability, supported by solid BMS protection and durable construction, giving travelers a strong foundation for off-grid living or extended trips.

FAQs

What types of batteries are available for RV or camper use?

The RV and camper battery options include LiFePO4 (lithium iron phosphate) batteries in 12V, 24V, and 48V configurations, available in capacities like 100Ah, 200Ah, 400Ah, and more. These deep-cycle lithium batteries are lightweight, long-lasting, and ideal for powering RV electrical systems efficiently.

What is the difference between lithium and traditional lead-acid batteries?

Lithium (especially LiFePO₄) batteries deliver higher usable capacity, lighter weight, faster charging, and longer cycle life compared to lead-acid. Lead-acid is cheaper upfront but offers less usable capacity, a heavier weight, and a shorter lifespan. 

Are LiFePO4 batteries safe for my RV or camper?

Yes. LiFePO₄ is among the safest lithium chemistries due to high thermal stability and lower fire risk. But safe use still requires correct charging systems, BMS protection, and adherence to manufacturer installation guidelines. 

Which battery is best for my energy needs and camping style?

Select an RV and camper based on your voltage system (12/24/48 V), daily energy usage (kWh), depth of discharge, and off-grid duration. For light use, a 12 V 100Ah works; for a serious off-grid rig, go for 5 kWh+ capacity models. 

How do I calculate the battery capacity I need for my camper?

Estimate your daily power consumption (in kWh), multiply by the number of days off-grid, then choose an RV and camper that provides that usable energy after accounting for depth of discharge (~80-90% for LiFePO₄). Match to the correct voltage system. 

What is the typical lifespan of these lithium batteries?

LiFePO₄ batteries typically deliver thousands of cycles, translating to 5-10 years or more of use under proper conditions (charging correctly, avoiding extreme temperatures). 

Are these batteries compatible with my RV’s existing electrical system?

Potentially yes, provided your RV’s system matches the RV and camper’s voltage (12/24/48 V) and your charger/converter is compatible with lithium charging profiles. If your system is lead-acid only, you may need an update. 

How can I check if a specific battery model is in stock?

On the product page at King of Generators, you’ll see stock status (e.g., “In stock”). For certainty, you can contact our customer service at (855) 799 2943 or email us at info@kinggenerators.com to confirm availability.
