Both families are in production but carry longer part lists than we list here. Ask for the rack or bottle catalogue and we will send the current model sheets.
Most models can be run to a custom internal envelope. Send the cells you intend to use and the space you have, and we will confirm which shell takes it.
Every case here ships empty. Cells, BMS, harness and pack assembly stay with you — which is also why we can keep the minimum at one piece.
We do not publish a single figure, because there is not one. Colour matching, logo printing, cable-exit position, mounting hardware, mould amortisation and volume all move the number — and a housing quoted without knowing your cell format would be a guess. Send the frame envelope, the voltage, the cell format and the quantity, and you get a firm price, the internal envelope and a delivery date within five hours. From one piece.
