Sure, I could do that, but some things bother me about it:
I'm reliant on the inverter not to misbehave. The BatteryProtect was completely independent of the inverter. (I have a cheap inverter. I don't trust it to turn off).
If I don't have 12V loads, I've just bought a 65A switch to switch a...
One of the great benefits of the Victron BatteryProtect units is their tiny current draw while "on". Now with these updated suggestions to use a mechanical relay, the relay coil will be drawing a certain amount of power 24/7 to keep the relay turned on.
While I realise that the relay coil...
I've played with a 50Ah 12V NiFe bank - like you, my driver was the long life aspect. The biggest pain in the arse for me was the wide voltage swing. Connect a modest load (3-5A), and the voltage drops to 10V or less. Connect a modest charge source (~5A) and the voltage flies up to 17V unless...
I'd still be interested in knowing the absorption voltage for 90% SOC to be honest. I'm the sort of person who wants to be quite conservative with cell degradation, and I haven't yet found enough testing/research to be confident that regular charging to 100% SOC won't reduce cycle life. Or, put...
