【Automotive Grade Battery Cells】 Adopts automotive-grade battery cells for a 12.8V 100Ah lithium battery, allowing it to perform 4000-15000 cycles with a ideal battery cell structure. Which means our 100Ah battery produces 5120kWh (1280Wh*4000 cycles times=5120kWh) in its 10-year lifespan, which means you will save at least 1/2 of power fees compare with using the utility power 【2.6X Lightweight & Group 31 Compact Design】Timeusb 12V 100Ah LiFePO4 battery weighs only 24.25 lbs, BCI Battery Size-Group 31, only half weight and providing twice capacity in the same size as lead-acid batteries, you can easy to move and install. And our LiFePO4 battery is 100% usable capacity compared with lead-acid battery only provide 60%~70% capacity, which can be tested by a percent state of charge meter. 【1280Wh Usable Energy Output】2X increase in energy output efficiency over 12V 100Ah lead-acid batteries. 12v 100ah lithium battery can connect in parallel & in series for larger capacity. Allow being extended up to 4S or 4P to get Max 400Ah capacity or Max 48V(51.2V) voltage, which can be widely used for solar RV system, solar home energy, off grid, trolling motor, boat, marine, UPS etc. 【BUILT-IN 100A BMS&5-Hour Fast Charging】12V 100Ah Lithium Battery builds in 100A BMS, which can prevent the LifePO4 battery from the most common issue causing of battery failure, such as overcharge, over-discharge, over-current & short circuit. Our 12V 100Ah Deep Cycle battery only needs a 5-hour fast charging time when charged by a 14.6V 20A LiFePO4 battery charger, saving 50% time in charging compared with lead-acid battery which needs 10 hours charging time to around 70% capacity. 【5-Year Warranty & US-Based Support】：Timeusb stands behind every battery with a robust 5-year warranty and lifetime technical support.
