Asking for some friends and family who are not yet on a full PV/backup/off-grid system, but getting sick and tired of replacing old 7Ah 12v batteries in UPSs, gate motors, alarms and garage motors.
Are the BlueNova LiFePO4 drop-in replacements, such as this one, any good?
What appliances would they be best suited for? E.g. a 2000VA UPS used for loadshedding to power a notebook & router, or a gatemotor opening and closing a couple of times during loadshedding?
Are there any caveats to them?
Has anybody here used them?
