OptiMate Lithium 4s Smart Battery Charger - AC to DC - 12V - 0.8 Amps

Video Transcript for Review of OptiMate Battery Charger - Battery Charger - MA34BR

Hello everybody, this is Jeff at etrailer.com. Today we take a look at this OptiMate Lithium 4s eight-step AC to DC smart battery charger and maintainer. Now, lithium batteries like the LiFePO4 and the LFP models, they're very good potential replacement for your lead-acid batteries in applications such as RVs, electric vehicles, motorcycles, boats, and even solar applications. And to help you maintain those lithium batteries, this compact smart charger here draws power from an AC wall outlet to automatically charge, test, and maintain those lithium batteries on your car, your RV, your boat, or your motorcycle. It is designed to work with 12.8 volt to 13.2 volt LiFePO4 and LFP batteries from one to 10 amp hours. What's also nice is this is able to help save your battery if it gets as low as 0.5 volts.

And it is a simple operation with the LED lights on it that'll indicate the charging status. Basically, just to show you. Now, I don't have it hooked up to any battery, but I just want to show you the lights. When we plug it in, you'll be able to see some of the lights, how they're flashing. But basically, those lights will indicate your charging status.

It also offers an auto memory feature, which remembers the last selection if power is lost. And it does use an eight-step charging algorithm, which will automatically save, charge, test, and maintain without overcharging. When you plug it in, it'll first analyze your battery condition to provide a customized charge for your application. It does test automatically and indicates if there's a battery problem. It will even safely wake the battery out of a sleep mode using the integrated BMS protection.

And also what's nice is on this, it comes with a nice set of printed instructions, but if you don't have this nearby, you can scan that QR code on the case and it'll give you those instructions on your mobile device. The case itself is a durable weatherproof case, and it does include the six-foot long AC supply lead that plugs into the outlet, and the six-foot long charge lead with an SAE connector. That'll connect to either one of these extensions here to connect to your battery. If you just want a temporary connection, it offers the battery clamps here. It's about a 20-inch long battery clamp connection.

Gives you the two battery clamps and the SAE connector that you would just plug into your charger. Once you plug that in, hook up to your clamps and you're ready to go. The other way, if you want a more permanent connection is they offer these eyelet cables that's also 20 inches long. This will let you make a secure connection to your battery terminals using these eyelets. And it also includes this 15 amp inline fuse here, which will protect the electronics from potential short circuits. And it also uses an SAE connector that plugs in, has a nice weatherproof seal around it So that when you plug it in, it gives you a nice seal. And if you're not plugged into the charger, it gives you a nice cap that you can put over there to keep out any dirt and water from your connection. Now the application, again, this is for 12.8 volt to 13.2 volt lithium batteries from one to 10 amp hours. And the battery types again is the LiFePO4, which are lithium iron phosphate batteries, and the LFP, which are lithium ferrous phosphate batteries. Maximum charging amperage on this is 0.8 amps. But that's gonna do it for the review on this OptiMate Lithium 4s eight-step AC to DC smart battery charger and maintainer.
