Update on DC House 50Ah LFP units from above ^
When I received them few weeks ago, both did not show any voltage when unboxed.
Not ideal, but I do so much with my LFP batteries I knew that the BMS* tripped.
(I'v had that happen while using my other batteries several times, so I knew what it was)
Simply grabbed another discharged battery with 11 or 12V and connected it like I was balancing batteries (pos. to pos. & neg. to neg.)
That takes the batteries out of 'tripped' BMS and then I could charged them normally.
All good
If I hadn't done that, no charger or solar controller would recognize it,,, and many people would freak out/scream bloody murder to the company.
..giving a one star review ect..ect.. bla bla
The manual say up to 15V out from the Type C,,, the barrel DC out is 5A @12v (haven't tested those yet)
Lastly, they've kept voltage right around 13.33V for weeks now,, so no unusual self discharge.
> they're light, easy to move around (y)
