Looking For Replacement For 1315-200 Battery Separator On 2008 Sportsmobile Van
Updated 09/15/2025 | Published 05/24/2025
Question:
I have a 2008 Sportsmobile and the house batteries are no longer charging while I drive. It has a Sun Power battery separator model 1315-200. I read online that these can go bad after 5-7 years, so I am thinking this is my problem. Do you have something that would replace it or any suggestions? Thank you for your time. p.s. I hear about you through Wild RV Life youtube videos.

Hey Kent, thanks for reaching out. We do have a suitable replacement for the Sun Power battery separator model 1315-200. For that I recommend the Redarc Smart Start Battery Isolator # 331-SBI212D. The dual sensing is the equivalent to the bidirectional functionality on your 1315-200. This will allow you to transfer charge from either your start battery or your auxiliary battery to keep both batteries in your setup charged.
I have seen a few of the Wild RV Life youtube videos, but I will have to check out more now :)
