The LiFePO4 12V 400 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 400Ah 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 400Ah 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 400Ah 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 400Ah 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.

Great battery, OK BMS App

The battery is great! I replaced my 100Ah LiFePo4 in my 14' fiberglass Armadillo Backpack trailer with this 400Ah battery. It's heavier and larger--but not four times heavier or larger. Customer service is responsive--I get responses to my questions. After installing it charged up to 397 Ah. I pre-ordered the battery and received a discount for it, although I had to wait a few months to receive it.

Spec. sheet--I wish it would be updated. The spec sheet is for the 300Ah battery, although only a few fields need to be updated and those values are available in the description here.

App--I know reBel Batteries doesn't supply the app. I searched for it in the Android Play Store (Apple app also available) using "Xiao Xiang 2" (小象电动 , which means Baby Elephant Electric 2.0). This is not the "Administrative" version of the app, which is supposed to have more control. But the Play Store app had what I need, such as the SoC and remaining charging time or remaining battery time. You have to press the button on the battery to enable Bluetooth to use the app (and pair with the battery). The button turns blue when on. Bluetooth uses a little battery, but it can always be disabled by pressing the battery button again.

Overall a great battery. Here's a YouTube video I made of the installation:
