Features

  • -Small Size, Large Capacity: The mini Wattcycle 12V 100Ah LiFePO4 Lithium Battery offers an 11% weight reduction and a 39% volume reduction compared to the excellent first-generation, while its energy density has increased to an impressive 63wh/lbs! A qualitative leap from traditional lead-acid batteries.
  • -More Compact: Weighing only 20.94lbs and measuring 9*5.4*8.2 inches, this means it's easier to carry. With the same battery storage space, you can accommodate more batteries, providing you with more power for your outings.
  • -Your Exclusive Bluetooth: After downloading the App, you can set the Bluetooth name yourself. Once connected, you can read the real-time status of the battery, such as voltage, charging/discharging current, alarm prompts, temperature parameters... This allows you to have a clear understanding of the health condition of your Lifepo4 battery and ensure its safe use. (Please note: Download WattCyle app. The display parameters have been updated. Please refer to the main picture for the display.)
  • -Grade A+ Cells: The EV Grade A+ cells in our 100Ah LiFePO4 battery ensure a lifespan of up to 10 years, withstand up to 15,000 cycles, and support a 4S4P configuration with a capacity of up to 20.48kWh.
  • -Low-Temperature Protection: The Wattcycle 12V 100Ah LiFePO4 battery operates in a wide temperature range (-4F to 158F / -20C to 70C). It automatically shuts off at low temperatures, ensuring maximum battery protection and performance in diverse environments.
  • -BMS Protection: The built-in Battery Management System (BMS) safeguards the 12V 100Ah LiFePO4 battery against overcharge, deep discharge, overload, overheating, low temperatures, and short circuits. It monitors battery status, manages charging and discharging processes, and ensures battery efficiency through individual cell balancing.

  • My Second WattCycle Battery
Style: 12V 100Ah Bluetooth Mini 100 BMS
This is my second WattCycle battery, and I like them both. The other one is a 12V 314Ah model that I use for bigger appliances. The 12V 100Ah one is my daily power bank that I can take anywhere. So far, both of my WattCycle batteries have been solid performers. Their customer support is quick to respond to questions as well. ... show more

Style: 12V 100Ah Bluetooth Mini 100 BMS
Junk is all i got to say. Bought a 3 pack of the 12v 100ah smart mini. Bought them for the size. Installed 2 in the boat. Charged them up and hit the water. Worked fine. Have charged them twice since installed. Every time they are fully charged i unplug the charger. Noticed the last time i was out the app said that they was low and not much time remaining. And SOC was low. Used them all afternoon and never died. So came home charged them up and plugged the charger. Few days later i connected to them and it said it was in the low 90 range on SOC. So i totally unhooked them and let them set. Checked again over next few days and still discharging at a rate of about 1 percent a day with nothing hooked to them. Company acts like nothing is wrong. So save your money and buy a better battery! Will update if something changes ... show more

I installed the battery on a refrigerated cooler that consistently drew the battery to 0. Eventually the abuse caused the battery to fail. Watt Cycle techs worked with me to understand and fix the problem. They gave advice on how to revive the battery. When we determined that the battery would no longer accept a charge they sent me a new one- free of charge. ... show more
