Review: REDODO Customer Service is excellent. Email you back next business day. - Great batteries at affordable price. Long term maintenance with INTERNAL BMS BATTERIES is a bit more work, as they should be rotated periodically and recharged and balanced, if you have more than one. If treated correctly, they will last for several thousand charge cycles. REDODO Customer Service is excellent. They respond the next business day by email. They stand by their products.
Review: Awesome Customer Service/Great Product - I recently bought three lithium iron batteries with 300 amp hours each from Redodo Batteries on desertcart, and I must say, I was thoroughly impressed with the product and the level of service I received. It's rare to find good customer service these days, but Redodo Batteries exceeded my expectations in every way. From the moment I placed my order, I was kept informed of the shipping and delivery process every step of the way, thanks to the excellent support provided by Lillian in customer service. When the batteries arrived, they were well-packaged and arrived in excellent condition. The installation process was made easy thanks to the detailed instructions provided, and the batteries themselves have exceeded my expectations in terms of performance and reliability. Throughout the entire process, Jack in technical support was incredibly helpful in answering all of my technical questions. He was patient, knowledgeable, and went above and beyond to ensure that I had a complete understanding of the product and how to install it properly. I was particularly impressed with the level of customer service that I received from both Jack and Lillian. They were friendly, helpful, and provided excellent support to me throughout the entire purchasing and installation process. Overall, I would highly recommend Redodo Batteries to anyone in need of high-quality lithium iron batteries. The product is top-notch, and the customer service is exceptional. Thank you, Redodo Batteries, for providing such a wonderful product and a great customer experience!

### ⭐⭐⭐⭐⭐ Great battery for a battery backup system.
*by R***. on February 26, 2025*

I have a home battery backup system that I put together a long time ago, and AIMs 3,000 watt (6,000 when needed) to run it. I originally used golf cart batteries, since they are true deep-cycle batteries since that is how they are used on a golf cart. I think I had the internal charger set a little to high for them. In time those batteries seem to be over charging or charging too fast and "boiling" off the water/acid, and uncover the top of the plates which soon ruined battery (after I had them for many years). But where I had them in my basement they should have been like AGM, but they never caused an issue. With LiFePo4 batteries they don't loose their charge sitting, and no explosive gas (hydrogen) in the basement. So I turned off the charger on my old AIM charger/inverter unit that is built for and RV or marine use, to run on shore power that it passes thru, and was using to charge the batteries. I bought a small charger for the 2 of these that I now have connected. Plus I did by a 50 amp charger for Lithium batteries, but I don't normally have it hooked up, but if I every have a long outage, I have it to get these charged up, more quickly. Not I currently have a small draw on this system since I have three 12 volt LED lights with a motion sensor that lights up our front door/porch when we come and go at night. I have thought about moving it to a 120V to 12V transformer so it would not use the batteries at all. These LiFePo4 batteries, only need charge like every 6 months, they say. I have thought about adding solar panels to the system, setup like an Arduino to monitor the system, and drop the line power to the system, when the solar is generating enough power to run the system, at least for awhile. Plus if we had an extended outage it could probably keep us running for at least the daylight hours. I have a pellet stove, and they require a little under 200 watts to run, so that is why I originally built the battery backup system. And the AIM inverter can signal a generator to start when the batteries get low. Or since they are 12V, I could probably rig up a car to recharge them if I had too. I bought pieces to add a generator to this system, but need to work on our old generator, or buy a new one.
