Frequently asked questions
Which battery works with Alexa 35 and Alexa Mini LF?
Those bodies use 28V B-Mount. The Protean, Protean 4, Artisan Block, SLi-D600 and SLi-D1000 all deliver 28V, and B-Mount plate options are available. Tell us your setup and we will confirm the exact build.
Do you have batteries for older Alexa Mini, SXT and Amira?
Yes. Those run 24V and use V-Mount or Gold Mount plates. Our 14.4V to 30V multi-voltage range covers them, including the SLi and INDY series.
Can one battery power both 28V and 14V cameras?
Yes. Protean, Protean 4, Artisan Block, SLi-D600 and SLi-D1000 are dual voltage, so a mixed Alexa and RED or Canon package can run off one inventory.
How is pricing set?
Some products have list prices, such as The Protean at $275 and the SLi-D600 at $2,150 with charger. Larger systems are custom-quoted based on your needs through our authorized dealer network.
Can I fly with these batteries?
The Protean splits into two isolated 75Wh batteries for carry-on rules. The SLi-D600 and SLi-D1000 disassemble for air travel. Lithium shipping follows DOT, IATA and IMO rules.
Do you rent batteries?
No. Block Battery products are sold, not rented. We sell through a national dealer network and also run fleet programs for camera rental houses.
