FAE Expert Insights
"The 2V500AH is our go-to solution for large battery systems requiring 48V or higher DC voltages. The 2V cell design offers several advantages over 12V monoblocs: better cell balancing, easier maintenance, and longer service life. I've specified this cell for numerous telecom central office installations and data center UPS systems. The 15-year design life reduces total cost of ownership significantly compared to standard 10-year batteries."
Excellent choice for large-scale battery systems requiring long service life

Frequently Asked Questions
How many 2V500AH cells are needed for a 48V system?
For a 48V system, you need 24 cells of 2V500AH connected in series (24 x 2V = 48V). For a 500Ah 48V battery bank, this would be 24 cells total. For higher capacity, multiple strings of 24 cells can be connected in parallel. For example, 1000Ah at 48V would require 48 cells (2 strings of 24 cells each).
Calculate system voltage requirement and divide by 2V to determine number of cells needed.
What is the recommended spacing between 2V cells?
Recommended spacing for 2V cells: Minimum 10mm between cells for air circulation; 20-30mm preferred for better cooling. Allow minimum 100mm clearance above terminals for maintenance access. For rack-mounted installations, follow the rack manufacturer's spacing recommendations. Proper spacing is essential for heat dissipation and to prevent thermal runaway in case of cell failure.
Follow installation manual spacing requirements. Ensure adequate ventilation in battery room.
Can 2V cells be mixed with different capacities in the same system?
No, all cells in a series string must have the same capacity and be from the same production batch when possible. Mixing different capacities will result in uneven charging and discharging, reducing system performance and life. For parallel strings, each string should have the same total capacity. When expanding existing systems, add complete new strings rather than mixing old and new cells in the same string.
Always use identical cells in a series string. Contact us for system expansion guidance.
What torque should be used for 2V cell terminals?
Recommended terminal torque for M10 terminals on 2V500AH cells: 15-20 Nm (11-15 ft-lbs). Use calibrated torque wrench and tighten in stages. After initial installation, retorque after 24 hours and again after one week of operation. Proper torque ensures low-resistance connections without damaging the terminal. Apply thin coating of petroleum jelly to prevent corrosion.
Use calibrated torque wrench and follow retorque schedule for reliable connections.
How often should 2V cells be equalized?
Equalization charging for 2V cells: For standby applications, equalize every 3-6 months or when cell voltage variation exceeds 0.05V. For cyclic applications, equalize monthly. Equalization voltage is typically 2.40-2.45V per cell (57.6-58.8V for 48V system) for 8-12 hours. Monitor cell temperatures during equalization and reduce voltage if temperature exceeds 45C.
Implement regular equalization schedule to maintain cell balance and extend battery life.
