$1,249

Charge Temp Range (°C): -20°C (-4°F) / 65°C (149°F)

WORLD’S THINNEST BATTERY! BigBattery’s 12V 1.76 kWh RZBK battery is the thinnest and safest solution for your RVs and other 12V applications.

At Big Battery, we pride ourselves on being energy innovators, and in only 1.5 inches of thickness, we’ve packed our advanced BMS, a 100A Breaker, and brand new LFP Razor cells. These cells are some of the safest lithium cells available today, capable of being fully punctured without releasing hazardous fumes or catching fire. When it comes to safety, the RZBK is unmatched.

If you’re looking for safe, portable, and discreet power storage, the RZBK is your answer. One of the most power dense units we offer, the RZBK can be paralleled together for a robust power system that doesn’t have to eat up valuable space and weight.
