Review: Read some bad reviews on this but have ran Renogy DC/DC for years (get new ones when I upgrade or change vehicles) and never had one problem.
Review: Works good, also got the BL2 bluetooth interface (cool that they give you a lower price option in case you don't need BT). The instructions are good (Made in USA), app works good, the until has lots of charge profiles and even current limiting. My only disappointment was that you can only choose from 10A increments for the current limiter. We get 10, 20, 30 and 40 and well I need 25... ohh well

### ⭐⭐ Review
*by D***I on 3 February 2026*

Charger works as advertised but there is a much larger than anticipated parasitic load when not charging. I estimate it to be about 1 amp. Drained a 100Ah AGM dual purpose battery from 12.7 to 12.0V in ~48 hours. Anyone else experiencing this? Is there a fix (softwear or otherwise)? This charger isn't useful for marine applications where there are often days to weeks between motor use with this magnitude parasitic load.
