Sterling PlanB Battery Innovations
PlanB’s innovations focus on increasing safety, performance and lifetime value.



CellSwap Battery Re-Coring
PlanB brings value in the marine battery market to a new level.
PlanB CellSwapTM is a retrofit process to rebuild the inside of a battery onboard a vessel.
PlanB CellSwapTM is simple; the cells in the core of the battery can be replaced when nearing end of life. Other items, such as electronics and racking, are reused. There is no need for costly refit of existing hardware, only the consumable parts such as the cells are replaced.
CanPower - Containerized Energy Storage
An independent containerized battery room within standard sized containers 20-53 feet in length.
Marine & Industrial
CanPower allows for a variety of installation opportunities in ships where insufficient room below deck may be an issue or for increased flexibility to add-on additional capacity on an as-needed basis. Other uses include shore power and mobile port energy.
Renewable & Grid Support
With the proliferation of grid-connected renewable energy sources, the task of stabilizing the power grid while making more efficient use of our energy resources has become a global concern. Stabilize the grid, reduce blackouts, or deploy emergency power instantly.

Why Choose Sterling PlanB
The safest, highest performing product delivered and serviced by one of the world’s most experienced marine energy storage teams.
System Options
PlanB uses the highest quality, highest performing lithium ion cells available. These cells are designed and engineered to provide years of performance in the most demanding industrial applications.
Power 65 (P65) is designed for high discharge power applications requiring high C-rates and faster cycling. It provides up to 15,000 charge/discharge cycles at 80% DoD.
Power 73 (P73) also provides up to 15,000 charge/discharge cycles at 80% DoD but with an improved energy density of14% for the same weight.
Energy 88 (E88) is for applications requiring lower discharge rates and greater energy density. A decrease in cost and weight provides the end user with a faster path to ROI and decreased footprint and weight.
