Everything below comes from what BYD Energy Storage publishes about the MC Cube-T BESS: the datasheet, the product page and press releases. Where a figure is not published, the field says so — we do not estimate.
Variants
Energy figures are usable as published by the manufacturer. One model, several duration options — the same enclosure with different power ratings.

| MC10C-B5010-E/U-R2 (5.0 MWh 2h) | 5.01 MWh | 2.506 MW | 2 h |
| MC12C-B6012-E/U-R2 (6.0 MWh 2h) | 6.012 MWh | 3.006 MW | 2 h |
| MC10C-B5365-E/U-R4 (5.4 MWh 4h) | 5.36 MWh | 1.34 MW | 4 h |
| MC12C-B6437-E/U-R4 (6.4 MWh 4h) | 6.431 MWh | 1.608 MW | 4 h |

Key facts
- Export (E/U) version of the MC Cube-T family launched April 2024; CTS (cell-to-system) integration of Blade cells
- Energy figures are DC usable @FAT; datasheet also gives @1-month SAT (4,950 / 5,940 / 5,306 / 6,366 kWh) and @3-month SAT values
- 10-cube units are 6,058 mm long (20ft), 12-cube units 7,550 mm; dimensions exclude the site-installed DMC HVAC; weights 43,550–53,010 kg
- Product page lists 5,365 / 6,437 kWh for the 4h SKUs; datasheet table shows 5,360 / 6,431 kWh
- 624 units supplied to the 446 MW / 3.5 GWh Elena plant (Oasis de Atacama, Chile), inaugurated June 2026

Price signal
$70–90/kWh
No public price list — estimated from Chinese tender benchmarks: H1 2026 average winning bids of RMB 541–602/kWh ($75–84, CNESA), export FOB-China for Europe at $71–89/kWh (SMM). Refers to the ex-works DC block; BYD has historically been the price leader in mega-tenders (12.5 GWh Saudi Arabia). Western turnkey installs run 2–3× higher.
