Advantages of Containerized Solutions pt. 2: Integrating Battery Systems
UPDATED MARCH 13, 2024

In part one of this blog series, we highlighted the advantages of containerized solutions. Some of the clear advantages include speed of deployment and time to market, reduced installation and integration time, and decreased upfront capital expenditure.
With that being said, which battery solution makes the most sense for integration with your UPS in modular construction?
There are some common concerns when approaching a containerized design versus a traditional stick build that needs to be taken into consideration, such as footprint, weight, and ease of install.
Comparatively, alternative chemistry batteries, such as lithium-ion or nickel-zinc are leading the way for modular data centers because of their extended lifespans, increased power density, and smaller footprints than the traditional VRLA offerings on the market.
Let’s break down the advantages of alternate chemistries versus VRLA in containerized solutions:
|
|
FOOTPRINTLithium-ion batteries possess a 40-60% smaller footprint, which is imperative in a modular design. Simply needing 2 more cabinets of VRLA batteries over an alternative could result in needing a container that is 10 feet longer!
Larger container = higher cost = more cooling, etc.
|
|
|
WEIGHTPossessing only 60% of the weight of comparable VRLA makes lithium-ion batteries easier to transport. Ultimately, this provides both flexibility and cost savings when shipping and installing.
Not to mention, many alternative chemistry solutions are now designed with enhanced transportability by pre-populating the modules within the cabinets themselves. Shipping pre-populated will also reduce installation time by nearly 60%!

LIFESPANVRLA options will require replacement every 3-5 years whereas with lithium-ion and other chemistries, lifespan is instantly increased to the 15-to-25-year range before reaching end of life (60% capacity).
Why is this important in a containerized solution? Limiting the number of entries into the container is vital in keeping your TCO down.

MAINTENANCEIt should be noted that maintenance is significantly reduced as well, as lithium-ion only needs one preventative maintenance visit per year. Battery replacement services are not expected to be necessary over the lifetime of the UPS.
An integrated battery management/monitoring system (BMS) is included when purchasing a lithium-ion battery solution – providing real-time data and trending as well as safety monitoring and control, which is vital within a containerized solution.

While there are many benefits to utilizing a modular design, it may not be the best fit for your application. We encourage you to discuss the pros and cons with your partners and vendors to ensure that you select the best solution for your application.
