charger overheating, throttling down, no fan

Hello all,

I try to charge a 280Ah 4S LiFePO4 battery with a blue smart charger 12/30.

After a few minutes charging with 30A, I noticed the current going down to ~17A while still in bulk phase. The charger was quiet hot. I assume it tiers down the current to not overheat, but the fan is still off.

I stopped charging and after a cool down started again. Same behaviour.

If the charger is getting too hot, why is it throttling down instead of activating the fan? (at least I can't hear any fan)

Charger is brand new, 1st time use.

Any help is much apprechiated.


Cheers,

luphi

Issue is fixed. After opening the charge, I figured out after some tests, that the fan was blocked by the ribbon cable connecting the top and bottom boards.

Just bending it a bit off the fan and it was working again. Currently charging stable at 30A for at least 1/2h.


Cheers,
