Victron Energy Smart Battery Protect 12/24 Volt 65 Amp (Bluetooth) Battery Protection

Its a bit expensive (nearly the price of a small battery itself) but:Easy to installEasy to bypass if you give yourself an extra 5cm of cable. OK you shouldn't do this but sometimes you just have to...Bluetooth is easy, don't use it much but useful for initial set upHas saved me from running a battery completely flat twice in the last 6 months so has paid for itself already.really good for any situation where you have battery maintained by a float charge

Don’t buy the 60amp version. Too weak.

For me this beats Victron Energies other battery protect, in that it can be set up through bluetooth to a wider range of voltages and above 12volts with my very large lead acid stationary batteries a large battery bank, I set to disconnect at 12.9v and restart at 13 volt, this works well with my current setup. I find theSmart BatteryProtect easy to setup, the best thing about this is I don't need to keep a firm eye on the voltage.If I come home late when the light is lost the most that'll happen is my system has switched off I won't find the batteries so low there life span is reduced.At night I mostly power my home on the mains, so far there has been more than enough power in the batteries to get through a power outage to run my very large fish tank, keep watching TV and have a light on.

I don't often write reviews, but on this occasion feel compelled to do so, after I bought the 200a smart Bluetooth system.I have a solar setup with 2 X 200ah lithium batteries in parallel, with 3 X 100w solar panels feeding them, controlled by a TS-MPPT-45 solar controller.I was surprised to find that when the lithium batteries hit LVC, no solar energy would go into recharging the batteries, and instead, the batteries would simply go to sleep.This device overcomes this problem as I can automatically disconnect the load before the batteries hit LVCThe Vitron Smart Protection system is extremely easy to install, and then set up via your phone. It uses BLE Bluetooth so has a super low energy consumption, and as well as a variety of presets for low voltage disconnect / voltage reconnect you can also use your own custom settings.I highly recommend this to anyone who has a solar / battery setup.

Hi I bought this unit but did not use it for a while because I was waiting on battery delivery.I have fitted one before which was not a smart unit which was ok. Victron have such a good name I took it for granted that it would work. If you buy a battery protect , I would advise you to test it straight away.

Unreliable Bluetooth connection.
