What Products Are on Sale This Prime Day?
Our entire LiFePO4 lineup participates, but the WattCycle 12V 314Ah LiFePO4 Battery leads the event as the flagship offer of Prime Day 2026, available in both a standard and a Bluetooth-enabled version.
Both models share the same core build: 4,019Wh of usable capacity, a 200A BMS, Grade A cells, and a rated cycle life exceeding 4,000 full charge-discharge cycles. For RV owners, vanlife travelers, marine users, and off-grid cabin setups, this level of capacity means real freedom from shore power and generator reliance on extended trips. Run your refrigerator, lighting, water pump, and devices without rationing power or watching a battery gauge.
The Bluetooth version adds real-time monitoring of voltage, temperature, and state of charge through the WattCycle app. If you manage a larger battery bank or spend extended time away from any service point, knowing your battery status on your phone at any moment is a practical advantage that goes beyond convenience.
Both models will be available at their lowest prices of the year during Prime Day. Stock on both variants is limited and will not be replenished at Prime Day pricing once depleted.

A note on the 12V 314Ah Mini Basic LiFePO4 Battery
Someone may have come across a recent social media discussion about internal component differences between units of this 12V 314Ah LiFePO4 battery. We want to address that directly. Our warehouse currently holds two production generations of the 12V 314Ah Basic LiFePO4 battery. The earlier generation uses high-quality three-strand stranded copper wire for the BMS connection. The current generation uses a flat braided copper conductor. Both versions meet the same electrical, thermal, and safety standards and have passed identical testing procedures. The change was a routine manufacturing update and It was a normal product update. and our internal testing confirms it has no effect on performance, reliability, or lifespan. For detailed information, please read this article: Official Clarification on the WattCycle 12V 314Ah Mini Series. We have provided comprehensive solutions as well as an internal structure diagram of the battery. Or you can read the WattCycle 12V 314Ah MINI Test Data.
What New Products Are We Launching This Prime Day?
Two purpose-built products are making their official debut during this event, each designed from the ground up for a specific application.
WattCycle 48V 50Ah Golf Cart Battery
The WattCycle 48V 50Ah Golf Cart Battery installs as a direct drop-in replacement for aging lead-acid setups, built to the standard GC2 form factor (13.02 x 10.4 x 7.2 inches) to fit under the golf cart seat without any wiring modifications or system redesigns. If you are replacing a lead-acid bank, the installation process requires no additional hardware and no electrical work.
At 44.4 lb (20.14 kg), it sheds significant weight compared to the lead-acid banks it replaces, reducing cart load and protecting course turf with no performance trade-off. A 100A BMS manages 2,560Wh of usable energy, keeping power delivery consistent from the first hole to the eighteenth with no voltage sag as the charge works down.
EV Grade A+ LiFePO4 cells remove the maintenance obligations that come with lead-acid chemistry entirely: no watering schedules, no terminal corrosion, and no equalization charges between rounds. A rated cycle life of 4,600+ cycles at 100% depth of discharge means this battery is built to outlast conventional alternatives by over a decade. For extended range needs, up to four units can be run in parallel, reaching a maximum range of up to 100 miles on a single charge.
Prime Day Introductory Price: $499.99 (was $679.99) | Save 26%
After using code WattCyclePrimeDay, it costs only $460.00
WattCycle 12V 314Ah Truck Starter Dual-Purpose Battery
The WattCycle 12V 314Ah Truck Starter Dual-Purpose Battery was built for one environment specifically: the long-haul truck cab, where the battery needs to start the engine at 5 AM and keep the air conditioning running until 6 AM the next morning.
It delivers 1,800 Cold Cranking Amps (CCA) for dependable engine starts across a full range of weather conditions, paired with 4,019Wh of deep-cycle capacity to sustain cabin loads through extended overnight parking stops. The 200A BMS handles continuous discharge from air conditioning units, refrigerators, televisions, and additional appliances without voltage sag or thermal stress, regardless of how long the draw is sustained.
The dual-purpose architecture means drivers carry one battery that covers both engine starting and house power, removing the weight, cost, and complexity of maintaining separate starting and house battery systems. For drivers working to reduce engine idling time while keeping the cab comfortable through the night, this battery was designed with that exact situation in mind.
