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 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.
