Questions before quotation

Which capacities are available in this wheeled BT Series?

Current models provide 10 and 15 kWh at 51.2V.

Do the wheels make these batteries portable power stations?

No. Listed weights are approximately 85–105 kg. The wheels support on-site positioning rather than hand-carried portability.

How should buyers choose between 10 and 15 kWh?

Selection should consider target storage, load requirements, charge/discharge current, parallel quantity and installation space.
