12V 50Ah LiFePO4 Battery — Deep Cycle, Bluetooth BMS, IP65

The 12V 50Ah LiFePO4 battery from Safecloud Power is a factory-direct deep-cycle lithium battery engineered for B2B buyers who demand reliable performance, OEM flexibility, and verifiable quality. Built with Grade-A LiFePO4 cells (CATL / EVE / CALB), a built-in smart BMS, and Bluetooth SOC monitoring, this battery delivers 3× the usable capacity of an equivalent AGM battery at 60% less weight — with a 6,000+ cycle lifespan that outlasts lead-acid alternatives by a decade or more.

CE, FCC, CB, and UN38.3 certified. OEM branding, custom BMS parameters, and private-label packaging available from MOQ 10 units. Sample delivery in 7 business days.

Why B2B Buyers Choose the Safecloud 12V 50Ah LiFePO4 Battery

Distributors, OEM brands, and system integrators across North America, Europe, and Australia rely on this battery for one fundamental reason: it consistently performs in the field with defect rates below 0.5% per production batch. Here is what makes it different from generic alternatives:

Bluetooth SOC Monitoring — Standard on Every Unit

Real-time state of charge, voltage, temperature, and cycle count visible on your customer’s smartphone — no additional module required. This is the feature that reduces after-sale support calls and drives repeat orders from your B2B buyers.

Integrated Smart BMS — Multi-Layer Protection

Overcharge (OVP), over-discharge (UVP), overcurrent (OCP), overtemperature (OTP), short-circuit (SCP), and active cell balancing — built directly into every pack. The BMS is the most frequently substituted component in budget batteries; ours is specified, not generic.

Grade-A LiFePO4 Cells — Traceable to Origin

CATL, EVE Energy, and CALB cell options available, all Grade-A with factory QR traceability codes. Cell brand and model are specified in every purchase contract — not substituted after sampling. IQC capacity and resistance testing on every incoming batch.

IP65 Waterproof Rated

Dustproof and jet-water resistant enclosure — suitable for marine bilge areas, RV underbody mounting, outdoor solar installations, and any application where moisture exposure is expected during operation or transport.

6,000+ Cycle Life — Lower Total Cost of Ownership

Over 6,000 full charge/discharge cycles at 80% DoD — equivalent to 16+ years of daily use. Compared to AGM batteries (300–600 cycles), the 12V 50Ah LiFePO4 battery delivers a total cost of ownership 60–70% lower over any 10-year period. This is the financial argument that closes B2B sales.

60% Lighter Than Lead-Acid

At approximately 6.5 kg versus 16–18 kg for an equivalent AGM, the weight advantage directly impacts payload capacity, fuel economy, and installation flexibility in weight-sensitive applications such as kayak fishing setups, camper van roof installs, and portable power stations.

Application Scenarios — Where This Battery Performs

The 12V 50Ah LiFePO4 battery is designed for mobile, marine, and off-grid applications where weight savings, deep-cycle capability, and low maintenance are critical. Typical B2B buyer profiles and their primary use cases include:

• RV & Camper Van Distributors: Drop-in lead-acid replacement for travel trailers, pop-up campers, and van conversions. Compatible with most existing 12V RV charging systems with a LiFePO4 charger profile.
• Marine Accessory Wholesalers: Trolling motor battery for kayak fishing, small aluminum fishing boats, and pontoon boats. IP65 housing survives bilge splash and damp storage conditions.
• Off-Grid & Solar Dealers: Ideal for small solar backup systems, garden sheds, remote cameras, and portable power setups requiring 640Wh of reliable storage in a compact form factor.
• Portable Power Station OEMs: Internal power source for branded portable power stations, camping generators, and emergency backup units — with Bluetooth monitoring for user-facing SOC display.
• Security & Telecom Installers: Float-charge compatible backup for remote cameras, alarm systems, and communication equipment. Self-discharge rate <3%/month ensures reliable backup after extended storage.
• Industrial Equipment Brands: Power source for AGVs, pallet jacks, cleaning equipment, and light-duty electric vehicles requiring compact 12V deep-cycle power with Bluetooth fleet monitoring.

Quality Control — IQC, IPQC, and OQC on Every Batch

Every 12V 50Ah LiFePO4 battery shipped from Safecloud Power passes through a three-stage quality control process:

• IQC (Incoming Quality Control): Every cell batch tested for capacity, internal resistance, and open-circuit voltage before entering production. Non-conforming cells are rejected before assembly.
• IPQC (In-Process Quality Control): Spot checks at cell sorting, welding, BMS integration, and module assembly stages. Production records maintained per batch number.
• OQC (Outgoing Quality Control): 100% capacity test, BMS function verification, hi-pot test, and visual inspection before each unit is packed for shipment. Defect rate target: <0.5% per batch.

Third-party pre-shipment inspection (SGS / Bureau Veritas / Intertek) supported on request — with no additional factory-side restrictions.
