48V 400Ah Lithium ion Battery in Renewable Energy Applications

If you’re looking for energy storage for your residential solar system for grid-tie or off-grid, this 48V lithium battery is a great option. Deep cycle batteries are a key component in off-grid solar electric systems, and for grid-tie or emergency backup power systems with or without solar. For renewable energy systems, the 48V 400Ah Lithium ion Battery is compatible with Outback, Schneider Electric, Magnum, Morningstar, and many other leading brands of inverters and solar charge controllers.

48v 400ah lithium battery

BSLBATT lifepo4 batteries adopt durable internal structures to ensure they are suitable for the toughest conditions, such as high charge and discharge currents, humid environments, and mechanical shocks or vibrations. These lithium-ion batteries are well-defined performance, and long-term stability, keeping efficiency, and last much longer than conventional batteries, giving you peace of mind and saving time and money on maintenance and replacements.

Advantages against Lead Acid battery:

1. Weight: Less than half the weight of the lead acid battery.

2. Discharge: Lithium-ion batteries are discharged 100% versus less than 80% for lead acid. Most lead acid batteries do not recommend more than 50% depth of discharge.

3. Cycle Life: Rechargeable lithium-ion batteries cycle 2000-5000 times or more compared to just 400-500 cycles in lead acid batteries.

4. Voltage: Lithium-ion batteries maintain their voltage throughout the entire discharge cycle. This allows for greater and longer-lasting efficiency of electrical components. Lead acid voltage drops consistently throughout the discharge cycle.

5. Cost: Despite the higher upfront cost of lithium-ion batteries, the true cost of ownership is far less than lead acid when considering life span and performance.

6. Environmental Impact: There are far fewer disposal and environmental hazard posed by lithium batteries compared to short-lived and toxic lead acid batteries.

7. LiFePO4 battery is the most stable and safest among other lithium-ion batteries.
