Question 1

How long does a 1 kWh battery last?

Accepted Answer

It depends on the devices connected. A 1 kWh (1000Wh) battery could power a 100W fridge for about 10 hours, a 60W laptop for about 16 hours, or charge a 10W smartphone around 100 times.

Question 2

Does higher battery capacity mean longer lifespan?

Accepted Answer

Not necessarily. Capacity refers to stored energy, while lifespan depends on charging habits, temperature, and battery type. A high-capacity battery provides longer runtime, but its longevity still depends on proper usage and maintenance.

Question 3

Can I expand my battery capacity later?

Accepted Answer

Some portable power stations and solar batteries support expansion modules, allowing you to increase capacity when your energy needs grow. Always check product compatibility before purchase.

Question 4

Is 5 kWh battery enough for a house?

Accepted Answer

A 5 kWh battery can meet the basic needs of a small household—running essential appliances like lights, Wi-Fi router, fans, and a small fridge for several hours. However, for households with higher energy consumption (air conditioners, washing machines, or EV charging), 5 kWh may be more suitable as backup rather than full-day coverage.

The GODE DQ1911 All-in-One LiFePO4 Battery Energy Storage System is a flexible and reliable solution, featuring an integrated BMS and 5.6 kW inverter, making it ideal for home backup power and solar energy applications.

Question 5

How long does a 5 kWh battery last with normal household use?

Accepted Answer

On average, a 5 kWh battery can power a small home for 4–8 hours depending on consumption. For example, if your home uses 1kWh per hour, it will last around 5 hours. If you only run essentials like LED lights and a fridge, it could last even longer.

Question 6

How long will a 10 kWh battery power a house?

Accepted Answer

A 10kWh battery is a popular choice for residential backup. It typically provides 8–12 hours of electricity for a medium household, covering refrigerators, lights, TVs, and even short use of high-power appliances like microwaves or washing machines. For energy-efficient homes, it can support overnight needs comfortably.

Question 7

What does a 10 kWh battery cost in 2025?

Accepted Answer

The cost of a 10 kWh battery system in 2025 varies depending on technology, brand, and whether an inverter is included. Industry prices typically range from $4,000 to $8,000, with high-end integrated systems priced slightly higher.

For homeowners seeking a balance between cost-effectiveness and performance, the GODE DQ1906C5K6 All-in-One Energy Storage System is an excellent choice. It comes with a 5.6 kW built-in inverter and is priced at just $1,500, supporting up to 6 units in parallel. This ensures a long cycle life, competitive total cost of ownership, and seamless integration with solar panels.
