Hello,
I would love to ask about the settings for charging lifepo4 batteries. In my van I am using a victron Orion-Tr Smart DC-DC Charger 12/12-30 Non-Isolated and Victron SmartSolar MPPT 100/030. I set the lifepo4 presets on both devices. Absorption voltage is 14.2 and floating 13.5.
Is that all right, or should I set different values? I am attaching specifications for my battery.
Many thanks!
I'm more or less new to this myself , but I think the defaults are correct.
The BMS will stop the charge when the battery is full , But on mine I've dropped Absorption voltage to 4.05 , because my battery has a Bluetooth monitor which said a cell was going over voltage , so I dropped the Absorption voltage and increased the Absorption time a extra hour.
They say 14.6V for absorption and don't specify float. So you can increase absorption, float should be ok at 13.5V. Tail current is 4%.
Thanks for both answers. What if I don't increase absorption voltage, will it just charge longer, or I can damage battery or its will not be fully charged?
It will take longer and the battery won't be fully charged.
Shouldn't do any damage.
Many thanks! Will set voltage to 14,5V just to be safe that its not too high, but still enough, that battery manufacturer recommends 14,6 +/- 0,2 V
