EXR Battery Control Unit (BCU) Question

[VINSANITY]

Liquid Performance has battery control units (COATED 2103779-02) for sale on e-bay.

Does anyone know if this will work on a 2019 EXR

 

[Redwolf]

Presumably if it's for an R pack, it would work. If it's for an A pack, not so much.

 

[VINSANITY]

Does the 2019 EXR have an R pack?

 

[Redwolf]

Yes.

 

[Mark911]

It's for the R pack for sure. Note, you'll need to buy or swap out the two contactors.

 

[VINSANITY]

Thanks Mark

Can you purchase the contractors somewhere and how are they installed.

@VINSANITY did your BCU go out or just preparing for worst?

 

[Mark911]

Thanks Mark

Can you purchase the contractors somewhere and how are they installed.

Yes, they're commercially available. I know the A pack part number but not the R pack, sorry. However, search the site as I'm pretty sure someone posted the part number somewhere.

A packs uses the P105-006 minitactors

R packs uses the P125-007 minitactors

A couple of times after charging everything went dead when turning the key on. It cleared itself after sitting for a while. I have checked the cells either computer and they seem OK.

I think the BCU and or contractors may have a problem.

Contactors are not going to be easy to remove from the lid. From the looks of it the contactors were first installed on the BCU, and then the cavity that they nest in must have had a predetermined amount of some epoxy product applied, then the BCU/contactor assembly must have been set in and allowed to cure. Going to take some careful work to remove so as to not damage the lid itself.

Thanks for responding - looks like a pretty tricky job

I bought the BCU off eBay and got a price on the contractors from gigavac

I thought I would get the parts and keep using the bike as it seems to be working fine right now

Double check with Gigavac. They were not able (or willing) to match the exact part number when I emailed them for a quote. I gave them the part numbers @Oded supplied, they returned a different part number, I asked for verification that the part was identical, then no reply.

A packs uses the P105-006 minitactors

R packs uses the P125-007 minitactors

this is the exact catalog name of the A pack's contctor - P105BDA
P105-006 was a name probably used for Alta only, but they are the same.
