Hello everyone, i'm new and need a confirmation for my setup.
It's for a Van, I plan to get :
- 150 ah (4/12b with BT) on aliexpress (LiitoKala with this spec :
----
Grade: Grade A
Capacité nominale: 150Ah
Minimum capacité: 130Ah
Impédance interne: 0.1 ~ 0.5mΩ
Tension évaluée: 3.2V
Constante de courant recommandée: 150A (1C)
Tension de terminaison de décharge: 2.0V
Courant constant recommandé: 450A(3C)
Tension de charge: 3.65V
Courant de décharge continu maximal: 900A (6C)
Cycle de vie (DOD 90%): 6000

To use this battery I will :
- Install a solar panel (330w max)
- Install a 12/230 converter with max 300/600w (won't use more than 200w un the same tile on 230v with a laptop and small stuff.
- Use some tiny stuff like small fridge or 12v led etc.

I can't make the math but a 60/80a BMS (Daly) should be "large" for m'y purpose right or I'm missing something ?

Thanks and sorry for m'y bas english.

I probably got my answer ?
Power (W) = 12V x 60A = 720W
It's gonna fit my need.
