I believe the fastest way to destroy a deep-cyle battery is to continually drop its depth of charge to below 50% to 40%.
Has anybody fitted a low voltage disconnect (LVD) system to the their caravan house battery so that it automatically cuts the power when the battery is discharged to 40%? Normally, you only know when you have discharged the battery when the lights go dim and this if done routinely, I am told, the battery life can be shortened to months.
I am interested to know if such devices are readily available and at what cost.
My budget won't stretch to solar panels at the moment, so I have depend on recharging the battery from the car when I travel. I have run heavy gauge cable (approx. 10 mm square) from the car auxilliary battery to the caravan via a 50 A Anderson plug.
