## Features

- ✅ SMALLER SIZE BUT POWERFUL: WEIZE mini 100ah battery is 25% smaller than before but provides the same power (1280Wh energy). Engineered with Lithium Iron Phosphate (LiFePO4) technology made this battery has half the weight, and lasts 5 times longer than a lead acid battery. It is a perfect upgrade for any 12V Deep Cycle battery, and best choice for many applications such as Fish Finders, Ice Fishing, Camping, Solar System, or Home Alarm Systems, wherever you want without regard for space.
- ✅ BUILT TO LAST: Our 12V 100Ah Lithium Batteries live more than 2000 cycles at 100%/8000 cycles at 50%(Suggested) depth of discharge, without decreasing in performance. The average lifetime of lead-acid batteries is about two years(500 cycles) at just 50% discharge. This basically means a LiFePO4 battery will last you at least 5 times longer than a lead-acid battery, which actually reduces overall cost. It has cold weather protection which is critical.
- ✅ AUTOMATIC BMS AND MAINTENANCE-FREE: The built-in Battery Management System (BMS) protects your battery from Over Charge and Discharge, Over Current, Short Circuiting, as well as Low and High Temperature for increased performance and longer life. The BMS will automatically cut off the battery and the voltage will drop below 1V. Only when the circuit is cut off, the battery will automatically reactivate after 1 second(No longer need a higher voltage input to activate).
- ✅ SAFE AND ENVIRONMENTALLY FRIENDLY: Made from 100% safe, nontoxic, not hazardous energy, Weize LiFePO4 battery has higher chemical stability, it is not prone to thermal runaway and will not overheat or catch on fire even if punctured. With no acid in the battery, you're able to safely mount in any position.
- WEIZE battery is intended for use as an energy storage purpose, Please do not use this battery as a car battery, starting battery, or golf cart battery. We do not suggest using it to start any device!

### ⭐⭐⭐⭐⭐ Do it
*by M***P on January 12, 2026*

Game changer, the life on this when running a trolling motor is exponentially better than a lead acid. You won't regret it just buy it. But make sure you get a proper charger. The battery size is small the power is mighty
