Leave your battery plugged in during storage without guessing what it's doing. This 12V AC charger uses built-in Bluetooth for live charge data and programmable settings, so you can check real charge status instead of relying on LED indicators.
A lot of chargers leave you guessing if the battery is actually charging or just sitting in maintenance mode. Built-in Bluetooth fixes that with wireless monitoring, configuration, and firmware updates through the Victron app, and the charger also logs lifetime usage data plus detailed statistics for the most recent 40 charge cycles. You can check voltage, current, charge stage, and recent charging history instead of reading between the lines, so it's easier to spot real charging activity and catch a battery that isn't responding.
Fixed-profile chargers can be a bad match when you're charging different battery types or trying to fine-tune long-term storage behavior. This charger uses an adaptive 6-stage charge algorithm with microprocessor controlled battery management, and it gives you adjustable absorption, float, storage, recondition, and temperature compensation settings. It also supports lead acid and Li ion batteries with a dedicated Li ion bulk, absorption, and float algorithm, so you can program the charger around the battery instead of forcing the battery through one generic cycle.
Long parked stretches are where a lot of batteries get cooked by constant float charging or quietly run down. The built-in storage mode lowers float voltage during inactivity and periodically restores absorption voltage, which cuts battery maintenance and aging during extended connection. For trailers, RV batteries, or bench charging in the garage, that gives you a charger you can leave connected for weeks or months without treating storage like a full-time charging cycle.
Deeply discharged batteries can leave some chargers sitting there with no output because they don't see enough voltage to begin charging. This unit initiates charging from zero volts, and it can reconnect to Li ion batteries with internal disconnect protection. When a battery has dropped hard or a lithium battery has gone into protection mode, the charger can restart the process instead of stalling out at connection.
Heat and noise become more noticeable when a charger stays connected for long stretches or runs in tighter indoor spaces. This charger operates at 15 amps in normal mode with up to 94 percent efficiency, and NIGHT and LOW modes cut output current to 7.5 amps while eliminating noise. It also uses overtemperature protection that automatically reduces output current as temperatures increase while continuing operation, so you get steady charging behavior with less heat buildup and a quieter setup when full output isn't necessary.

Hi, everybody. Andy here with etrailer. Let's take a quick look at this Victron Blue Smart 12-Volt Battery Charger with Bluetooth. Now, this is a smart battery charger that's, again, made for your 12-volt batteries. And this is designed to be simple to use, but very high quality. At its core is a 12-volt, 15-amp charger that's going to plug into your standard 120-volt wall outlet, like you'd find in a garage or a workshop.
And this is meant for charging and maintaining batteries in things like RVs, boats, off-grid systems, or backup power setups. And what makes this stand out is that it is smart and Bluetooth-enabled. So once this is connected, you can monitor and adjust everything from your phone using Victron's app, such as charging status, voltage, battery type. And all of that's gonna be very easy to see at a glance and to manage as well. You're not gonna have to worry about some separate monitoring system.
So as you can see, I'm just trying to get this back in here, just like that. (lid snapping) So this is very well-constructed. It is constructed of aluminum, so I think it's gonna hold up really well for you. This does use adaptive, multi-stage charging process. So it's not just gonna dump power straight into your battery.
This is gonna charge it efficiently. And this is gonna taper off and maintain that battery properly, helping extend the life of your battery. So this is going to work with lead acid, AGM, gel, and lithium batteries. So being that that's the case, this is gonna be flexible if your setup changes later. So it's gonna grow with you, if you will.
Now, this model is a single output charger. So this is going to charge one battery bank at a time. It is IP22 rated, meaning this is intended for dry, indoor locations, like your garage, your shed, or electrical cabinet. And let me go ahead and give you some measurements here. I'm trying to find my ruler here. So looking at what is going to be the height, overall, we're sitting pretty close to about 9 11/16 inches. And then, looking at the width, pretty close to 4 5/16 inches. (battery charger thudding) And the depth, about 2 5/8 inches. So if you're looking for a reliable, well-built smart charger that's gonna be easy to monitor, that's gonna be easy on your batteries, and it's really trusted in the professional and off-grid setups, this charger from Victron is gonna be a great option for you to consider. If you happen to have any other questions, whether it's about this or anything else that we have here at etrailer, don't hesitate to reach out. We do wanna make sure that you're getting exactly what you need. Well, again, my name is Andy. Thank you for joining me.

Called late in the day Chris was able to get the item for me great service!!!!
Great charger for lithium batteries.
Quality process is easy. E trailer does not provide customers with accounts like Amazon or Walmart or others. so, every time you order online you have to input all of your information over and over again for every order. This is a barrier to sales. Please e trailer Please update your software. I love you guys but I'm not going to be answering my information over again and over again when I can just go to Amazon or Walmart or other places.
This is the perfect charger for my DIY power bank. I especially like the size and ease of use. I downloaded the Victron app to monitor and control the charger settings.
Perfict size, works great, easy to understand instructions, easy to set up.
It does what I expected it to do, I especially like the multiple lite display that show the state of charge and the type of charge.
