Review: Good Batteries-Excellent Customer Service - 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!
Review: high quality and reliable battery - Excellent battery that works really well with my RC mower project! Nominal voltage is around 40v so it can be a replacement to the 40v power tool batteries. The terminal lugs are also high quality.

### ⭐⭐⭐⭐⭐ Waited to make review after I beat them up
*by M***. on January 15, 2025*

All I can say is WOW. I bought 16 of these for my expedition marine trawler with 2000w of solar. When I am at anchor I have a full size residential fridge/ a large box freezer/ and a large ice maker/ wine cooler PLUS all the little items that run on the boat. These batteries for last 6 month have had the hell beaten out of them between the solar panels and the diesel generator pumping 100amps of charge through the huge inverter. EVERY day these things get beat on and randomly bank charged from diesel generator and charged by the main drive diesels alternators etc. these things pump out power and take huge charges from all sources. We had 7 people on the boat for 4 weeks and I will say I am IMPRESSED!!!! Way better than my firefly AGM bank they replaced. Bravo for such an great product at such a killer price point ($180 per 100ah battery) Took a chance from buying the expensive battle Borne batteries to save a TON of money,,,, And it is paying off so far!!!!! I’ll update next year after I continuously beat of them moving forward!!! Buy them. You won’t regret
