For those that have been waiting for the 12V 314Ah LFP battery to go on sale, here is your opportunity to grab it for Prime Day sale.

This is $499 on WattCycle's site and there is a 6% discount on there but here is a special 10% discount, instead of the 6%, which makes the price $450 before tax.

Yes I have been following Will Prowse's 2nd time review of this battery and WattCycle posted a reply to Will located here: https://diysolarforum.com/threads...ds.126309/

Good to see that they actually responded and take accountability.

- WattCycle 12V 314Ah Mini LiFePO4 Battery: 4019Wh Capacity Beats 12V 300Ah LiFePO4 Batteries—supports 4S4P expansion to 64.30kWh. Perfect for RV camping, solar energy storage, home backup, trolling motors, and marine applications.

- 50% Higher Current: Oxygen-free copper braided wires power 2000W+ devices, making it a top upgrade from 12V 300Ah LiFePO4 Batteries. Ideal for heavy-duty use like off-grid tools or RV appliances.

- 200A BMS + All-Weather Protection: Built-in BMS prevents overcharging/discharging, plus aluminum cooling fins for 30% faster heat dissipation. Low-temp cut-off (-4°F) ensures reliability—matches 12V 300Ah LiFePO4 Battery performance in harsh conditions.​

- Durable Aluminum Frame: Internal metal structure eliminates swelling, paired with IP65 waterproof ABS case. Safer than standard 12V 300Ah LiFePO4 Batteries, passing IEC/
ROHS/CE/FCC/UN38.3/Class9 certifications for long-term use.​

- 15,000 DOD Cycles: EV Grade-A cells deliver 10+ year lifespan—outlasts 12V 300Ah LiFePO4 Batteries and lead-acid options. Faster charging, lighter weight, and no complex wiring for hassle-free setup.​

- Compact Mini Design: 9.76"H x 15.12"W x 7.64"L size saves space vs. 12V 300Ah LiFePO4 Batteries. Weighs 62.5lbs (50% lighter than lead-acid/AGM/SLA), easy to install in RVs, solar setups, or marine vehicles.

That guy who tests the battery's is pretty thorough. So much so that one of those battery companies is threatening to sue him. It's a laughable premise. Some companies make out right dangerously designed batteries. It's nice to know there's companies doing things right.
