eSMART BC1150 Battery Combiner/Coupler

The Audioroot BC1150 is a six-bay portable smart battery combiner/coupler compatible with any smart battery with the Inspired Energy contact configuration (sold separately) including the Audioroot eSMART Li-49Wh, Li-98Wh, Li-48neo and Li-96neo batteries. It provides up to 588 Wh of energy in a small form factor and lightweight 1150 rugged Pelicase.

This product is designed to help location sound recordists use several portable <100Wh SMBus li-ion batteries together to power larger equipment configurations. Batteries can be easily installed and removed from the coupler to allow air transportation, battery replacement or use with smaller portable current distributors such as the BG-DH MKII. A mix of different battery sizes (4S1P-short and 4S2P-long) can be installed inside the coupler.

Power from the six batteries is combined and delivered by an XLR4F DC output connector. An external power supply can be connected to the high priority XLR4M DC-IN connector. The eSMART BC1150 is directly compatible with the eSMART BG-DU and K-ART.

A built-in 2 x 4A sequential charger allows recharge of the batteries without removing them from the device. The charger power source (24V) is connected via the XLR10F connector.

An eINK display shows individual battery levels as well as combined battery level, current, temperature and estimated runtime.

The BC1150 can recharge batteries during use (i.e when drawing current via the DC OUTPUT) with certain limitations :

• MAX current output AND simultaneous battery charging can only be achieved if both the BC1150-24V and BC1150-PSU are connected to the BC1150
• If only the BC1150-24V is connected batteries will effectively recharge only if current draw via the DC OUTPUT connector is <= 4.0A
• In any case when batteries are charging the BC1150 generates a small amount of noise (fan and small internal relays from the sequential charger)
