I haven’t used my BlueSmart IP67 charger for over 6 months as solar has been adequate, but now when I run the charger, it’s only staying in absorption for a maximum of 30 minutes, even though the battery is only at 90% and happily accepting 7+amps. I haven’t changed any settings in this time (only ever used defaults) although there has been a firmware update.
Is there any reason why this is happening?
6 months ago it would stay in absorption for several hours under the same circumstances.
