The Block Battery SLi-D1000 Lithium-ion 970Wh Dual Simultaneous 14V / 28V Block is a versatile battery designed for cinematic production applications. Utilizing innovative design concepts, the SLi Series provides an advanced feature set, including QuickCell modularity and AutoBalance technology. The SLi-D1000 features dual simultaneous voltage outputs (nominal 16V DC output via two XLR 4-pin connectors, and regulated 28V DC output via two XLR 3-pin connectors). Charges from empty in approximately 6-7 hours.

NOTE: While Block Battery has designed the SLi-D1000 to make it as easy as possible to ship and service, it is still restricted to one of three types of transportation:

  1. A completely assembled SLi-D1000 features 970Wh capacity. As such, if you wish to ship a completely assembled block, it must be shipped via an authorized Class 9 Dangerous goods shipper (via ground shipping ONLY).
  2. The Li-ion cells in the SLi series are easily removed by design. By detaching the rubber boot and removing the four bottom screws, the bottom of the block slides free. The internal cell cartridges can simply be unplugged for shipping. If you would like to ship the system via GROUND without shipping as Class 9 Dangerous Goods, simply ship all 10-97Wh cartridges disconnected and individually wrapped in one box (consult the shipper for proper labeling) and the housing in a separate box.
  3. It is possible to ship the SLi-D1000 using air cargo shipments. Each cartridge is only 97Wh @ 3.2V, and will need to be discharged to 30% prior to packing. Remove all cartridges from the battery case and ship them in the same box as the battery case. Be sure to use the proper packaging and labeling for the carrier selected (i.e., UN3481 labels).
