SmallBMS charger connection

I have SmartLithium 200ah 12v battery, smallBMS, cyrix-li-charge, 2 Orion 12/12 30a and Phoenix Smart charger. Apart from the Victron devices, there are 2 Epever MPPTs that do not have a remote control. My questions are: 1- Can the SmallBMS Charger output activate the Cyrix-Li-Charge on contact 85, as it only has 10mA available? 2- Can the SmallBMS Charger output be distributed to the Cyrix-Li-Charge, the 2 Orion 12/12 30a Isolated and the Phoenix Smart Charger?

@Juliocolle I've heard that epever mppts are prone to blowing up when the battery is disconnected from the battery while charging.

Better do some research on that.

1. The datasheet for the SmallBMS states that it can be used with the Cyrix-Li-Charge.

2. If you are connecting 4 devices to the allow to charge output of the SmallBMS then I would use a Victron SolidSwitch 104. The SmallBMS ATC turns the SolidSwitch on/off and the SolidSwitch with its higher current rating can turn multiple chargers on and off.

Can I use the Cyrix-Li-Charge just as an auxiliary relay to supply 12v to remote 2 Orion and Phoenix?
