  • Good Batteries-Excellent Customer Service
Style: 12V100Ah Pro
Good high quality true deep cycling batteries built tough with excellent customer service. Although I've installed a lot of solar since the 1990's, I am now sold on using Lithium Iron Phosphate on home solar installations to replace more typical lead-acid type batteries. Also perfect as an RV house battery. First thing I noticed was that their "Users Manual" was exceptionally well written and easy to read without any confusing language or translation errors. This was a welcome beginning. Communication with the seller, Time-USB is also nothing less than excellent. They gave me a heads-up when the batteries shipped, and they arrived very well packaged with plenty of protection and sooner than expected. If you have technical questions regarding set-up, the folks at Time-USB will be happy to walk you through the process quickly. I worked with Tanya and Gerri, who I found very knowledgable, easy to understand and answered all of my questions completely. I'm liking these new batteries because they are much lighter than Lead-Acid, much safer than most other Lithium-ion types, and if they work as specified, they will be far less expensive in the long run. Unlike lead acid, which can only tolerate about a 50% depth of discharge on a regular basis, you can discharge these all the way down without damage thanks to the built-in battery management circuitboard, or BMS. Although you will get more cycling lifetime if the depth of discharge is more conservative. These batteries work wonderfully along with a good quality, properly configured charger or solar charge controller, like the Morningstar Tristar MPPT series pictured, although custom settings were required. I'm also using Victron's BMV-712 Smart Battery Monitor with Bluetooth to easily and remotely monitor the system's production, battery status and power usage. Another nice thing about LiFePO4 (or LFP) is their very high (99%) charge efficiency compared to lead-acid at 94% or much lower as they age. Speaking of age, if installed and configured correctly, you should theoretically be able to get up to 5x the cycling life from these Lithium Iron Phosphate (LFP) type lithium-ion batteries, perhaps up to 10 years making these a perfect choice for off-grid solar or similar high cycling, high demand battery systems. Lastly, if you should have a problem, Time-USB tech support will resolve it, they also have a 5 year warranty on their products. I've ordered from them 3 times, and always had a good experience. Quality Built Tough! ... show more

  • Great product and supplier
Style: 12V100Ah Pro
My third battery purchase which should tell you that I am a very satisfied customer. Product and price are great and so is the customer service. Great care given to packaging and documentation as well

  • Excellent case design. Good BMS.
Right now this is the best price per amp hour on the market, even when compared to plastic case batteries. Delivered by FedEx 3 days from placing order in a well padded box with hand grips for the delivery guy. I'm using a smartshunt to measure capacity and it's spot on 220Ah after complete discharge to shutoff. There's really no need to remove two dozen small phillips head screws to see what's inside this great metal case - you can do some research online and make some educated guesses. I expect you would discover a 150A BMS made by Shenzen SaiHang and four massive BYD blade batteries in a nicely spaced, strapped and padded package. You'd likely find silicone wires and solid solder joints on the BMS along with a high temperature cutoff sensor stuck to the side of the pack. There's a warranty so don't open the case to find out. I certainly didn't since I want my warranty. The metal case is well made but isn't tied to ground. It doesn't have a spot designated for a ground terminal that I can find. The handles on top will get in the way if you plan to stack these. They unscrew easily or you can rig up spacer feet on the bottom corners - that's what I did because I'm still building out my solar system and my batteries are only temporarily placed. The handles really help in moving around the substantial weight and the adhesive feet keep the metal off my concrete floor. TimeUSB's customer support reached out to me with advice on what solar equipment settings work best and how to properly charge the battery. I'm impressed with their support - they are far more knowledgeable than most tier-1 agents. Other companies customer support typically repeats a mantra about charging the battery fully to unlock no matter the question. I bought three more of these to make a 48V system while the price is still low. One is at 227Ah. The others are still under test. ... show more

  • Don't waste your money on "big name" batteries, get this instead
Style: 12V100Ah Pro
Replaced my lead acid with this 100Ah LiFePO4 battery in my travel trailer. Connected to a charging inverter and a solar system. Works great, high quality cells, and a fraction of the price of Battleborn or some other brand name. I know it's scary buying an uncertain brand but this is a great battery. I only knocked 1 star off because it doesn't have low temperature protection built in. Seems an odd choice by the manufacturer. ... show more

  • Great for 24V Trolling Motors
Style: 12V100Ah Group24
I purchased these batteries to replace a couple of older AGM group 27 batteries that only lasted four years. I purchased two of the group size 24 batteries to save space and hooked them up in series for my 24V trolling motor. These batteries are very high quality and incredibly light compared to the old batteries! They provide amazing power and longevity compared to my old lead AGM batteries when fishing. Also, due to being a little lighter, I also get a bit more speed on my boat and less drag, further extending the life of these batteries when fishing all day. And the cost of these is considerably less than buying new AGM batteries, and they'll likely last years beyond what a regular lead battery will last! It's really a no-brainier if you need to replace or upgrade your boat trolling motor batteries. Shipping was fast, and the customer service team has reached out a couple of times to make sure everything is going smoothly. I would highly recommend these batteries for your fishing trolling motor needs. ... show more
