BT-NLC 500-2 12 kWh 48V-power-pack

High-tech NLC-power-pack of 24 cells, type 500-2

12 kWh*, 48-Volt-power-pack

* The specified capacity refers to the recommended usage of 50 %, meaning the actual nominal capacity is twice as high!

Package consisting of 24 pieces of the "type CG-NLC 500-2" cell with a voltage of 2 V and a capacity of 500 Ah each!

The cells have a closed, salt-resistant housing. Maintenance-free and usable in any location.

The C-rate indicates the discharge time of the capacity. Most manufacturers specify the capacity at C100 to show higher values, but we refer to a discharge time of 10 hours, which is the C10 value.

Applications

• Home energy storage systems for UPS, solar, and wind
• Mobile applications: motorhomes, boats, utility vehicles, etc.
• Smart grids, grid stabilization, and microgrid systems

Accessories

• Bridge cables for connecting the individual cells
• Operating instructions (in German)

Payment Information

When paying in advance, if delivery times exceed 14 days, only a 30 % deposit is required. The remaining balance is due 7 working days before delivery.

Outside the recommended settings and values, performance and lifespan will be reduced.

Discharge Characteristics at 25 °C

Number of Cycles Based on Depth of Discharge

It is evident that the 2-Volt NLC cell achieves 4800 cycles at a 50 % depth of discharge. Even at 70 % utilization, it still reaches 4300 cycles. This is remarkable compared to conventional lead-acid batteries.

Comparable (but more expensive) OpzV (VR L) branded batteries only achieve 3000 cycles at 50 % usage and, due to their calendar lifespan, are dead in eleven years!

The slightly cheaper OpzS (V L) batteries only reach 2900 cycles at 50 %. The special feature of NLC technology is that the new lead-carbon technology achieves a 4-fold slower sulfation!
