China 48V 50AH Stackable LiFePO4 Battery - High Capacity, Lightweight, Long Life | Eco-Friendly Suppliers & Factory
Features
Smart BMS (Battery Management System)
Built-in BMS to protect the battery from overcharge, over temperature, over discharge, over current, low temperature and short circuit.
Superior Thermal Stability & Safety
LiFePO4 chemistry resists thermal runaway and combustion risks, even under extreme conditions, ensuring unmatched operational safety for high-stress environments.
Extended Cycle Life
With over 3,000-5,000 charge-discharge cycles (80% capacity retention), these batteries deliver long-term reliability, drastically reducing replacement frequency and lifecycle costs.
High Energy Density
Compact and lightweight design maximizes energy storage capacity per unit, ideal for space-constrained applications.
Eco-Friendly Composition
Free from toxic heavy metals (e.g., cobalt, lead), LiFePO4 batteries align with global sustainability standards (RoHS compliant) and enable easier recycling.
Low Self-Discharge Rate
Minimizing energy waste and ensuring readiness for seasonal or emergency use.
Wide Temperature Tolerance
Performs reliably in extreme climates (-20°C to 55°C / -4°F to 131°F), making it adaptable for outdoor solar storage, marine, and automotive applications.
Maintenance-Free Operation
No memory effect or routine upkeep required, reducing user intervention and total ownership costs.
Safer Metal Case
Safety valve and metal case design, can be fire and explosion proof, better quality than the general battery case. Flat shape with side-mounted screws allows the battery to be stacked for placement. It has a more stable built-in 50A BMS to protect it from overcharge, over-discharge, charge over-current, discharge over-current, short-circuit, cell voltage self balance, high-temp discharge cut off.
Frequently Asked Questions
What is the role of the built-in Smart BMS?
The built-in Smart Battery Management System (BMS) acts as a safety shield, protecting the battery cells from overcharge, over-discharge, over-current, short circuits, and extreme high or low temperatures to ensure optimal performance and longevity.
How long is the expected lifespan of this LiFePO4 battery?
This battery delivers an extended cycle life of 3,000 to 5,000 charge-discharge cycles at 80% Depth of Discharge (DoD). This long-term reliability significantly reduces the frequency and cost of battery replacements.
What makes the metal case design safer?
The metal casing features a robust, fireproof structure and a built-in safety valve to release pressure, preventing combustion risks. Its flat shape and side-mounted screws also make it highly stable for stackable configurations.
Can this battery operate in extreme temperatures?
Yes, the battery has a wide temperature tolerance, functioning reliably in environments ranging from -20°C to 55°C (-4°F to 131°F), making it ideal for outdoor solar storage and marine applications.
Is this battery environmentally friendly?
Yes, LiFePO4 chemistry contains no toxic heavy metals (such as lead, cadmium, or cobalt). It is RoHS-compliant, eco-friendly, and much easier to recycle than traditional battery types.
Does the battery require regular maintenance?
No, this battery is completely maintenance-free. It has a low self-discharge rate and no memory effect, meaning you do not need to perform routine checks or top up fluids.
