==== READ FULL DESCRIPTION, GENERIC BIDS WILL BE DISCARDED ====

We are looking to put together a 12S LTO BMS.

The BMS will need to fit an existing form factor.

The following features are required:

Equalization discharge current: 25mA

Wireless communications: NRF24L01+ or similar

Coulomb counting: up to 20A

The battery modules will be stacked into a HVDC pack. A control module will centralize all communications and orchestrate cell balancing, etc.

LTO chemistry is tolerant to 0V discharge. The BMS module must work with voltages 1-5V/cell. It must handle overdischarge gracefully and start back up when cell voltage > 1V.

See attachment for form factor. More details will be provided when the project is awarded.

When bidding, please provide:

- Work hours estimate

- Relevant past experience

Generic bids not relevant to this description will be discarded.
