Recently came across the “Victron Energy BPR065022000 Smart BatteryProtect 12/24V-65A”
Would this be a good thing for me as I recently ruined a set of two AGM batteries in my Airstream. I let them discharge below the correct voltage level and didn’t recharge them for two months. (I had no experience with these batteries and the acceptable voltage range–I now have that experience!)
My rig is 12v and max shore power is 30a.
Looking for your advice and suggestions.
THANKS!
Yes you can use it for this. You need to buy a 65A, 100A or 220A unit depending upon your maximum current draw. The only problem you have is in choosing what voltage to set it at because under heavy current draw the battery voltage sags, but the battery can still be full. But if you choose to low a voltage to allow for large voltage sag, then when you only have a small draw, i.e. you have left a single light on, then the battery can be flattened before it reaches the cut off. No one can give you a specific voltage because systems vary in battery capacity, type and current draw.
Thanks!
I already have the shunt “Battery Monitor BMV-712 Smart” but struggling to install it with my Airstream’s battery cables and the M10 bolts…
Appreciate this forum!
Please be aware that the BatteryProtect range is unidirectional in operation, so for discharge protection you’ll need to separate your wiring at the batteries - only the loads can run through your BatteryProtect, you must not run a charger through it.
