How to Build a Home Backup Power System with Aolithium Batteries?

Lithium-ion batteries have been widely used in portable electronics, electric vehicles, and grid storage due to their energy consumption and throughput. Lithium batteries are low cost, have a high energy density, and maintain long cycle life; it is widely used in innovative DIY projects by utilizing 12V 100Ah batteries, creating a portable power system.

Here are a case of DIY home backup power system with Aolithium 12V 100Ah batteries.

Meet Gina, she was an Air Force Veteran based in remote areas of Reno. Gina enjoyed her time living on a luxury school bus along with her husband. She joined Air Force back in 2005 in the healthcare management department and was stationed or deployed at various military remote bases like Nevada, Carolina, etc. She belongs to a military family with a major influence on living and values. She enjoyed her military role and responsibilities at such a young age and credited her time in the military as helping to improve her living. 

She got retired from Air Force after serving 20 years and joined the City College of Washington as a lecturer. At Washington, she lives in an apartment at second floor and pays $1500 monthly rent for her room. Along with Gina, four other people are also living with her in a shared apartment with separate rooms. Gina and her fellows are enjoyable and productive people.


At a certain time, they face electricity failover, so they need a gas generator to keep as a backup for the apartment. When the power goes out, Gina encountered the difficulty of igniting the generator and keeping it maintained, fueled, and ready to operate. Therefore, she now decided to get rid of the gas generator and upgrade the home backup power system using Lithium Batteries.

Gina with her apartment fellows executed the DIY project and planned to build a Lithium-ion battery-based power backup system which is trouble-free for them and small enough to easily portable while still having enough power to get over any domestic power outages. Gina researched about the several batteries that she wanted to use for the backup system and subsequently found LiFePo4 (lithium iron phosphate) 12V batteries as the most satisfactory solution for electricity storage and long life usage. She finds it easy to relocate with a reasonable combined size system with various exceptional features. She also liked the feature that they charged 100% for storage and no power lost after being stored for a few months.

After finalizing, she orders a high-quality standard Lithium battery of 100 Ah (Ampere Hours) that will store about 1.2 kWh (KiloWatt-hours) which costs her around $600-650 on Amazon's online store. She discovers that these batteries give enough power capacity to keep a home refrigerator or freezer functional for about 24 hours.

As per her research, she gets two of the Aolithium 100Ah 12V LiFePO4 Batteries with a Bluetooth feature that checks usage statistics and the state of charge on a mobile phone. Furthermore, these LiFePo4 batteries can connect in parallel to add more power to your backup system. Since they are 12V batteries, there is no chance of being electrocuted while operating with them. Gina added her comment that you need to be cautious not to short-circuit the two poles, as this will melt any wire if a circuit breaker is not connected to it.

Gina and her apartment friends fixed two 100Ah batteries and connected them in parallel (200Ah x 12V = 2.4 kWh) housed in a plastic container; now, they have about 2.5 kWh of electricity. Moreover, this power backup is small enough to facilitate them to carry back into their minivan when they want to go on road trips.

For charging these batteries, she buys very powerful chargers that will recharge them in a couple of hours. She also recommends going for a Smart IP65 12-Volt 5-amp Battery Charger with Bluetooth features that contain many safety features and prevent you from doing anything that damages your batteries.

Gina is the immense motivation for anyone looking for a DIY home backup system. As per her analysis, this backup system that they put together comprises enough power to be accommodating long hours’ power outage. Finally, their apartment is fully equipped with power backup to avoid any hassle and store all their perishable food that needs refrigeration without any worry; also, all the essential household electronics that require power will operate intrepidly.
