Qidianfy 12V 100Ah LiFePO4 Lithium Battery

This battery stores enough solar power for my evening loads. It has made my small system much more useful.

This is excellent for moderate 12V use, but I would not buy it expecting to run everything in an RV. Use it within its limits and it is great.

After 6 hours of fishing the batteries were still at 98% charged. Exactly what I wanted while shaving off 40 pounds of lead acid battery weight.

I had a question about charger voltage before installation and got a helpful answer. The battery itself has worked well.

The two batteries arrived a few days after I ordered them and they were well boxed in heavy duty boxes with solid styrofoam sheets inside as packing material.

I have used it for camping, garage power, and a few outage tests. It has charged correctly and delivered steady power each time.

As mentioned in title I've returned to building another battery bank of Qidianfy 12volt 300AH batteries. Last year I was making the transaction on my class C motorhome from a 320 AH Lead Acid battery bank to a 420 ah Lithium bank supported by a 600w solar array, big improvement in bank weight. After doing a lot of research (to me) on this process and then finally communicating with Qidianfy customer service to reassure my controller setup notes I had outlined along with their posted online suggested battery settings. Making sure all batteries are at full charge when starting systems is good practice.
I've been quite pleased this past year with Qidianfy's Lithium batteries and have decided to build an off-grid outbuilding system for my tractor/workstation. Looking forwarded to this new system.

It works great in normal weather, but the cold charging limits are important. I like the protection, I just plan around it.

I use it for portable radio equipment and small accessories. The voltage stays stable and the battery is easy to carry.

For short outages and outdoor use, this has been a strong little battery. It is easy to charge and easy to store.

It is light and compact, but you still need to plan the mounting spot and cable routing. After that, it is easy to live with.

The runtime is much better than what I was getting before. I can use more of the battery without worrying so much.

The battery fit neatly and made the battery compartment look less crowded. I also like not having to vent it like my old setup.

I would not expect one battery to run everything forever, but for basic off-grid needs it works very well. Lights, fan, and charging are easy.

It is not flashy, but it is practical. The size, weight, and capacity make sense for a lot of small 12V jobs.

It is important to use the right charger profile. Once I set that up, the battery charged and worked normally.

My trailer lights run longer and brighter than they did on the old battery. The lighter weight is a bonus.

This battery is part of my small backup kit with an inverter and charger. It is easy to store and useful when the power goes out.

I added a shunt monitor and the readings have been consistent. Runtime has matched my expectations.

I wanted something smaller than a 200Ah battery but more useful than a tiny backup pack. This hit the right balance.

It has low-temperature protection, but not self-heating. That is fine for me, but it is something to know if you camp in freezing weather.

If you need a straightforward 12V 100Ah LiFePO4 battery, this one is a solid choice. It is light, simple, and has handled my normal loads well.

It powers lights and electronics for weekend fishing trips. I appreciate not carrying a big heavy battery anymore.

This was a clean replacement in my 12V setup. I checked the charge settings, connected the cables, and it worked without a fuss.

I use it almost every day for small DC loads. It has been consistent and does not seem to lose charge quickly while sitting.

I started with one battery, but I like knowing the system can grow later. For now, one is enough for my needs.

I mounted it on a small cart for lights and charging tool batteries. It has been convenient and easy to recharge.

This little battery surprised me. It is not huge, but it runs my camp setup much longer than the old lead-acid battery.

I would have liked a small display on the battery. Still, performance has been solid and I can monitor it elsewhere.

I do not run air conditioning or big appliances from it. For lights, fan, water pump, and electronics, it is a really nice size.

The housing feels durable, and the terminals feel secure when tightened. It does not feel like a cheap battery.

I should have bought these batteries sooner! It was the wisest decision I ever made! My old electric boat motor batteries would only last 8 hours of fishing. Now I only need to charge them once every 24 hours, and they last for three days of fishing!

It pairs nicely with my 12V solar controller. The battery takes charge during the day and holds up well at night.
