Blue Smart IP65 Smart Car Battery Charger 12V 7A, Float & Trickle Charger and Desulfator for Motorcycle, ATV, RV, Lithium and Deep Cycle Batteries

I have a couple of other chargers, with LifePO4 capabilities, but I saw a review where this charger brought a dead LifePO4 battery back to life. That was not at all my experience. I have a Miady 36ah LifePO4 battery that I didn’t use for 2 years. I tried my other chargers and they didn’t do anything for the battery, so, after reading the reviewer state that this charger revived their dead batteries, I figured it was worth a try. After weeks of attempts at nearly every logical setting, the battery is still inactive. I really like the Bluetooth functionality and the detail of settings, so I highly recommend this charger; however, do not buy it to revive dead LifePO4 batteries. If the LifePO4 can’t be “jump started” then this charger will not provide any different results. Great charger and I’m still glad to have it, but it isn’t a necromancer of batteries.

Love how simple and easy to use this device is. The app works if you are into that kind of thing. The range on the bluetooth is a bit weak, but this is a battery charger. Also appreciate the recondition function and that it has a lithium battery setting.

Works well paired with the Victron Connect app to monitor via Bluetooth. Distance limited obviously.

I have used this once so far to recharge a 12 volt car battery that had gone slightly flat. Used the normal charge function to recharge it. It did a good job and using the VictronConnect app to monitor the process and different stages of battery charging was handy. A solid piece of kit.

At first it failed a firmware update and I couldn't connect to it without putting the phone on the back of the charger. A typical victron thing. Once it worked it's been good. I own 7 or 8 victron bluetooth devices and this is by far the device with the worst bluetooth module as far as range goes.. charger works as expected though

Been using this for about 2 years now, I wired it in place of my 12v converter in my camper trailer. Runs 24/7 and keeps my batteries charged up while using far less power than the converter used to. Victron products are all consistently great.

I have a bank of 4 12 volt 100ah lifepo4 batteries connected in series. My hybrid solar charger/inverter was 220 single phase, so I couldn't use the inverter part. I hooked up a 110 48 volt inverter directly to the batteries. Long story short one of my batteries was drained so bad it reversed its polarity. I tried all the fixes on the internet. None of them worked, I couldn't get the dead battery up to even 1 volt. I bought this charger as a last ditch effort. I put it on the charger and loaded the lifepo4 settings through the Bluetooth app. I didn't see any improvement after 24 hours and was just going to give up, but on the second or third day it was actually taking and holding a charge. After I'm done getting all my lifepo4 batteries to the same charge level I'm going to try it on a dead agm battery. Don't give up on it if you're in the same position I was in. UPDATE: it brought my dead 100ah agm battery back to life. It's been a full 28 days and we're now at close to 43ah and just shy of 12v. I had given up on this battery. It died just after the warranty was expired and sat dead nearly a year. I've tried other battery charges without any luck at all. Both the agm and lifepo4 batteries had to sit on the charger an extremely long amount of time, but it worked. If you have a dead expensive battery, don't give up on it. This is the best charger I have ever owned or used.

My Ctek 7002 charger started to go flaky on me so I decided to give this Victron a try. This is hands down a much better charger at a much lower cost. The Bluetooth App enables you to see exactly what the charger is doing at all times especially during the initial bulk and absorption phases. The App also allows you to customize many of the set points so you can set the functions for your particular battery (Odyssey, Interstate, Optima, etc.). Once set, you can forget about it for batteries/cars in long term storage. I am very impressed with this charger. Only time will tell if it is built to last, but so far it is excellent.
