Question 1

What makes Ultracell's rack-mounted lithium (LiFePO₄) batteries different from others?

Accepted Answer

The ULIT-R series is purpose-built for rack-mounted installation, using a true 51.2V architecture (16 cells in series) rather than a boosted 48V nominal voltage, which gives more consistent voltage output across the discharge cycle. It uses prismatic LiFePO₄ cells with an integrated BMS and passive cell balancer and supports common inverter communication protocols including CAN-Bus, RS485, and RS232.

Question 2

Can ULIT-R batteries be scaled for larger installations?

Accepted Answer

Yes. The ULIT-R series is modular, allowing multiple units to be connected in parallel to increase capacity, making it suited to installations that need to scale beyond a single unit's output.

Question 3

How long will ULIT-R rack-mounted batteries last?

Accepted Answer

ULIT-R batteries are rated for over 6,000 charge/discharge cycles at 80% depth of discharge, with a design life exceeding 15 years. This gives significantly more usable cycles than standard lead-acid, and more than the standard ULIT range's 2,000-cycle rating at 100% DoD, reflecting the deeper DoD basis used for each figure.
