Hello,
my e-scooter is based on 20s 40AH LiFePO4 prismatic cells and I charge it at 5A.
I have an overcharging protection which I designed which is based on a relais between the battery and the charger which disconnects as soon as 1 cell reaches 3.6V.
Unfortunately the relais contact kind of melted closed yesterday and so protection didn't kick in :-(
I realized that the relais was rated 10A @250Vac but only 1A and 110Vdc, so probably that is why it melted.

I seeking advice for a relais that can switch DC load > 5A:
- coil voltage 60V
- switching rate 10A 110V

Any advice?
