Can the battery be installed horizontally?

Yes, the WERCHTAY lithium battery is free from lead-acid battery safety issues such as battery leakage and battery corrosion, so it is perfectly fine to place the lithium batteries in any position.

Do I need to buy a special charger to charge this battery?

You can use an AC-to-DC lead-acid charger that is mains powered, as charging efficiency and duration are less of a concern,it cannot have automatic desulfation or equalization modes. If so,do not use it as there is a risk of damaging the cells or the battery.This can significantly shorten the life of the battery. If it has a simple bulk / absorption/trickle charge profile,it can be used to charge the battery but must be disconnected after charging and not left in trickle charge / maintenance mode.

When I receive this lithium battery, will it have enough power to use it right away?

Our lithium battery has 30% factory capacity,which can guarantee your basic usage at the moment. If you run out of 30% of power, you can use solar panels or utility power to recharge your lithium battery.

Customer Reviews

Overall rating: 5.0 / 5 from 7 reviews.

First off, I was impressed with the customer service from this company. After I placed my order, they reached out to inform me which warehouse my batteries were shipping from, who the carrier was, and even provided a tracking number. The batteries arrived quickly and exactly as described. These lithium batteries have been working perfectly, and I couldn’t be happier. They’re lightweight, easy to carry, and incredibly affordable for the quality they deliver. I’m so satisfied with this purchase that I’ll be recommending these batteries to my bass club members, as well as to friends and family. Great product, great experience—I highly recommend it!

12.8V 1280Wh/100Ah LiFePO4 Battery with BMS Protection

I installed this battery as part of a dual battery system in my Jeep Gladiator, primarily to power my fridge and other accessories while camping. It’s connected to both a solar panel and a 110V to 12V charger, and so far, it’s been working great! The setup has been super reliable for keeping everything running smoothly during trips, and the battery handles the load without any issues. Whether I’m off-grid or charging back at home, it performs as expected. If you’re looking for a dependable battery for camping or overlanding setups, I’d definitely recommend this one!

12.8V 1280Wh/100Ah LiFePO4 Battery with BMS Protection

I spent a lot of time comparing different options, and this battery stood out as the clear winner. The price was better than most competitors, and it checked all my boxes: small, lightweight, and powerful enough for my RV needs. So far, it’s been fantastic. While I can’t speak to its longevity yet, I’m very happy with my purchase. As someone older and not very strong, I needed a battery that was easy to lift, carry, and install—and this one delivered perfectly. The built-in handles are a lifesaver and made handling it much easier for me. Plus, it’s surprisingly nice-looking, which I appreciated even if it’s tucked away in the battery box. It also comes with a helpful instruction booklet, which made setup simple. If you’re looking for a lightweight 100Ah battery at a great price, I highly recommend this one. I’d buy it again without hesitation—no regrets here!

12.8V 1280Wh/100Ah LiFePO4 Battery with BMS Protection

We got this battery to use with the trolling motor on our kayak. It just arrived a few days ago, so we’re planning to test it out this weekend. The battery is incredibly lightweight, includes its own charger, and seems well-built. Based on the specs, it should easily provide several hours of power for our 10 ft. kayak while exploring the lake near our cabin. The 3-year warranty and 4000-15000 charge/discharge cycle lifespan are impressive, giving us confidence in its durability. We can’t wait to hit the water and see how it performs!

12.8V 1280Wh/100Ah LiFePO4 Battery with BMS Protection

This battery provides continuous power to my entire device. From my fridge to my lighting system, everything runs smoothly without any hitches. The 100Ah capacity means I don't have to worry about saving energy all the time. Solid construction. It's clear that this battery is built to last, and I've never had any issues with it, even with temperature fluctuations. This battery has been a rock during those unexpected power outages. It keeps my lights on and keeps me alert. I'll be buying another one as a backup.

12V 1280Wh/100Ah LiFePO4 Battery with BMS Protection

Outstanding battery. I purchased a 12V 100Ah Lithium Iron Phosphate battery to replace a 12V SLA battery that had deteriorated due to a pump failure. This battery is excellent, and it will eventually become part of the system. I added it to our current 12V system and it works great. The purchase process, shipping and delivery notification was excellent. So far I am very happy with the battery and the entire process with werchtay.
