The LiFePO4 12V 300 Ah battery is a drop-in replacement for lead-acid batteries.  These batteries have a longer service life, lighter weight, more efficient power, and all-around versatility.  Connect multiple batteries in parallel to increase storage capacity.

Our LifePO4 12V 300Ah comes with Bluetooth connectivity to monitor dozens of parameters via a connected App available on Android and iOS.

With Lithium Iron Phosphate (LiFePO4) batteries you have several advantages over lead-acid equivalents.  LiFePO4 offers 2500-7000 charge cycles depending on the depth-of-charge per cycle, while lead-acid is typically done after 200-300 charge cycles.

LiFePO4 also allows for 100% discharge, whereas lead-acid can not be drained more than 50% without damaging the battery.  If you buy a 300Ah lead-acid battery, you only get 150Ah usable Ah.  12v 300Ah LiFePO4 batteries provide 100% of the available Amps, with no ill effects on the battery.

If weight is a concern, our LiFePO4 12V 300Ah rechargeable battery weighs one-third of the lead-acid equivalent.

If all these advantages weren’t enough, you also get complete built-in protection on our 12v 300Ah LiFePO4 batteries with an advanced BlueTooth enabled Battery Management System (BMS).  It will protect you from short circuits, overcharging, over-discharging, over-current, as well as high temperature and low-temperature cut-offs.
