I was wrong. - Updated review - I made a mistake. I have a parasitic load on my system but it's not this DC DC charger. I pulled the charger out of the system and still had the same discharging of my batteries I was attributing to this charger. Adding the charger back into the system and no detectable difference to this discharge rate. This charger works great and it's easy to set up and modify the charging parameters through the app; which I really appreciate. Easy to set it up so it keeps my LiFePO4 house batteries at ~80% while my boat sits during the week. ---- old review ---- 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. Review: Great product - Excellent product.
