I have two Orion XS 50 charging tow banks of Optima AGM spiral (yellow) batteries and linked to a Cerbo GX. When controlled by the Cerbo GX, the Orion voltage charge in float mode is 16.6 V instead of the configured 14.7 V, which will toast the batteries quickly (if not already done since I realized that after a couple of hours). If disconnected (by software) from the Cerbo GX, they charge at the configure 14.7 V. Why is that, and is it a known problem?
Hi,
On the Cerbo GX they should be configured to charge an auxiliary battery:
Setings → Devices → … the Orion XS entry … → Settings → Output battery → Charging another battery from the main battery.
