Product Overview & System Integration

The Hemao 12V 50Ah LiFePO4 Battery for Solar & RV delivers a steady 640Wh nominal energy reserve within a standard drop-in replacement footprint for traditional SLA battery boxes. Engineered specifically for mobile off-grid power grids and residential solar storage loops, this lithium iron phosphate module features high vibration tolerance to withstand off-road RV conditions. The integrated internal hardware enables series and parallel stacking, allowing system integrators to scale storage configurations up to 48V or 200Ah with zero external balance wiring. Our factory handles full hardware modification, providing customized PCB charging cut-offs, custom length wiring harnesses, and specialized injection-molded casing colors for global wholesale procurement contracts.

Total Rated Energy = 12.8V*50Ah = 640Wh

Material & Technical Specifications

Quality Control & Global Standards

Our factory implements a zero-defect quality validation pipeline for every 12V 50Ah battery string. The production process involves automated laser-welding validation, cell capacity grading to≤2mΩ resistance variance, and an exhaustive 100% full-capacity factory test consisting of a 48-hour continuous charge-discharge aging protocol. Our manufacturing facilities comply with global shipping and safety regulations, backed by official TUV, CE, RoHS, UN38.3, and certified MSDS documentation for international ocean distribution.

Packaging & Logistics Safety

To guarantee transport safety under Class 9 Dangerous Goods regulations, each 12V 50Ah battery pack is encased in a dedicated double-wall UN-certified carton lined with heavy-duty shock-absorbing EVA foam blocks. For large-scale B2B distribution and EPC project delivery, cartons are consolidated onto fumigation-free wooden pallets, wrapped in high-strength anti-static protective film, and secured with structural steel strapping to maintain stability during ocean transit.

Typical Application Scenarios

This deep-cycle 12.8V 50Ah power module is widely integrated into solar-powered RV auxiliary grids, off-grid marine trolling motors, portable solar irrigation control boxes, outdoor telecom telemetry enclosures, and emergency backup power supplies for isolated traffic signage networks.

FAQ

Q: Can the 12V 50Ah LiFePO4 battery handle high-vibration RV environments without cell shifting?

A: Yes. The internal Tier 1 cells are locked inside a structural cell holder matrix with silicon dampening pads and heavy-duty busbars. This assembly mitigates the shock and vibration common to overland vehicles and marine engine bays.

Q: How does the integrated BMS manage charging inputs from high-output alternator charging systems?

A: The internal 50A hardware BMS limits overcurrent spikes to protect cell chemistry. When integrating into an RV alternator setup, a dedicated DC-to-DC battery charger must be installed to regulate voltage and maintain the proper 14.6V charge profile.

Q: What is the factory lead time for custom M8 terminal orientations and private label branding?

A: Private label laser printing on standard stock requires 5 to 7 working days. Comprehensive modifications involving custom terminal positions or alternative ABS casing molds require 25 to 30 days for complete engineering validation and structural tooling verification.
