10s4p: 360wh divided by two - 180

charger: 36v x 5a = 180w

Does that mean it is still fine (the charger says 36(42)v)?

If not, my 10s4p battery just became 10s5p :-/

You have 30Q batteries, right ? Let’s go like this: (nominal) (36V x 3000 mAh)/1000 = 108 Wh (per 10 s) 4 in parallel so 108 Wh x 4 = 432 Wh Giving chaka’s guideline. 432 / 2 = 216 Watts charging. 216 / 36V gives you 6 amps.

So your 5 amps should be clear of spec.

Edit: If I interpolate this on my 10s3p. I should only use 3,74 amps. The quick-charger is still the same at 4 Amps. Been using this for over a year with no noticeable degradation of the battery. So you even have some moving room.

I have a similar charger from Ali express. My fan doesn’t spin up when the psu is powered on, but as soon as I plug it in! FFS it goes loud AF
