12V 200AH Lifepo4 Battery Built-in 200A BMS and Bluetooth,12V Lithium Battery with 2560Wh,20000+ Deep Cycle Battery Perfect for RV,Marine/Trolling Motors,Solar,Home Energy Storage

This is for the Elefast 330ah 12.8v battery. I put it to the test my motorhome by running the A/C through the inverter and pulling well over 100amps. Remarkably there was very little voltage drop, <.2v and all the cells remained at same voltage indicating they were well balanced. And it had only #2 cables attached which got warm. I am impressed. I have used other LiFePO4 batteries that did not perform that well.

The battery arrived with a proper charge and in good shape. The case seems quite sturdy and the terminals feel very secure. This is a whole lot of battery for the money. It's installed now and working as intended. I couldn't get the Elefast app to download so I used the overkill solar app and it works fine with the BMS. I don't think you could buy cells, case and BMS for this price. I hooked it to a 2500 watt inverter and ran it to its capacity with resistive loads and the battery performed as it should. I couldn’t be happier with it.

Works great powering an 80# 24v terrova. Happy with it. I mounted it on its side to give myself optimal room in my boat. I charge it with a 16 amp 24v charger on low in 6-8 hours the day before I fish. I use it primarily to troll and have not ever used more than 50% running at roughly 2 mph

330AH battery arrived with 53% charge and then charge fully without issue. The battery is heavy but very light based on the AH available. I used a 20 amp charger and had no issue charging the battery. The cells are within .001 and .002 v which is great so no balance issues which is important for cell life. I’m very happy with the battery, price, and delivery. Bluetooth was important for me since I have 3 other batteries that use the same app. The app works great and connect no problem.

I purchased this 200ah LifePOV4 battery recently for a very small off-grid solar solution, but I have had a chance to work with the Battery Management System and run the battery through a few cycles. It is performing perfectly so far and is a great size for the amount of storage it provides. I would recommend this battery to anyone looking for a large battery solution, and at a very reasonable price.

I'm using it with an 80 pound thrust troller on my kayak and can go all 10 miles with the sonar on and still have 20 percent left.

When I started in my solar journey I knew absolutely nothing about it. After doing some very extensive research, I found the LIFEPO4 Battery. I chose this specific brand because it was compatible with my system and had good reviews. After purchasing one we realized we had to have a minimum of two to even be able to use the solar, so this is my second purchase from the same company. They literally shipped both of my batteries the very next day and I received it within 5 days! It's about 17 pounds, easy to install packaged very well. I also had to email them to get numbers to input into my systems controller. I received a response within a few hours! All I know is I'm still a bit confused about the solar system but I was impressed with Lifepo4 and will now continue to purchase all of my batteries

This battery is junk. This battery was installed in a small boat connected to a trolling motor, but unused. I charged the battery to full charge before installing. For the past 3 weeks the boat sat at a dealership waiting for some technical service unrelated to this battery. When the dealership got to my job yesterday, they found that this battery had less than max voltage, and when a load was applied, the voltage dropped to less than 3 volts. Return window closed 3 days ago! Really!!!!!!!
