URGENT Arri 235 battery in LA - owner operators can you help?

[Davo McConville]

Hi all!

 

Sorry for hijacking the forum but we have an emergency - we have a shoot tomorrow (Tuesday) - Friday and our Arri 235 batteries are dead.

 

Does anyone have onboard batteries or a 30v block we could rent please?

 

In LA!!

 

Many thanks

 

Davo

Keslow camera should have the on-board Anton Bauer mount. Otherwise you can use an Anton Bauer 12/28 belt

If anyone knows of a place that has specifically re-celled the factory Arri 235 on-board batteries successfully, I would love to know. I've heard a few varying stories that range from, "no problem", to "the battery packs are kind of glued in there a bit and you have to scrap off all this excess glue and that makes them a bit more difficult". Thanks in advance.

Thanks Kenny!

 

I tried but in the end we rebuilt them ourselves.

 

Todd – it takes a minute but it's not hard.

 

22 Standard AA NimH cells - 1.2A, Mah 1700-2100 – flat top / solder tabs

 

Reuse the thermistors etc from inside the battery (not hard to disassemble) and rebuild based on what you see in there.

 

You'll probably need to score the tops of the batteries to make sure the solder sticks (the Arri cells are electro soldered).

 

Every single battery needs a tab top and bottom.

 

They've then glued the block together, but regular glue gun glue won't be heat resistant enough to replace it with.

 

We recelled 4 batteries in about 5 hours.
