Important notice for our customers in Belgium: An environmental fee of €317.90 (excluding VAT) applies to the purchase of each Delong LVM15 lithium battery (15.36 kWh). Please add the corresponding product when purchasing this lithium battery. See the bottom of the page for more information. |
| Why choose the LVM15 Mobile version? | |||
|---|---|---|---|
| Total mobility | Scalable capacity | Real-time monitoring | Grade A CALB cells |
| System fitted with sturdy castors and ergonomic top handles for effortless movement. This design allows you to adjust the position of your energy storage unit to suit the layout of your plant room. |
Up to 15 units can be connected in parallel to achieve a maximum energy storage capacity of 225 kWh. A modular solution that adapts to your growing needs, from residential to remote industrial sites. |
Integrated front LED display allowing you to instantly monitor the state of charge (SOC) and system performance. Direct access to critical data (voltage, current, cycle life) for total control of your installation. |
CALB 314Ah prismatic cells, globally recognised for their thermal stability and longevity. Grade A guarantees consistent actual capacity and maximum protection against overheating, unlike reconditioned cells. |
The LVM15 series is based on a 16-cell series configuration (16S), guaranteeing a nominal voltage of 51.2V.
Unlike traditional fixed storage systems, the Delong LVM15 redefines ergonomics:
The choice between the LVM15 Mobile version and the Top Energy Stackable version depends mainly on your environment and your usage.
| Criteria | LVM15 Mobile model | Stackable Version |
| Installation | Ready-to-use solution (Plug & Play). No complex assembly or internal wiring required on delivery. | Requires modules to be stacked sequentially and inter-battery connection. |
| Maximum | Maximum. The unit can be easily moved for maintenance operations or to reorganise the space. | Fixed without a base. Solution designed for permanent and definitive installation in a dedicated plant room. With the optional base, this battery also becomes mobile. |
| Footprint | Compact vertical tower format with castors. Optimises floor space whilst remaining self-contained. | Scalable modular design. The total height varies depending on the number of storage modules added. |
| Ideal use | Residential properties, offices, data centres or homes requiring simplified maintenance and mobility. | Fixed residential installations, dedicated premises. |
The verdict: Choose the LVM15 Mobile if you’re looking for immediate installation without assembly and the ability to move your power source. Opt for the Stackable version for a more aesthetically integrated, less mobile solution and slightly higher capacity per module.
