Smart Battery Box Series 2

G'day Lyn,

The Engel Smart Battery Box Series 2 is just an inverter box so doesn't actually have an internal battery, you would need to purchase a deep cycle battery separately to use in the unit. If you're needing to run a 12V fan while away from your vehicle then you could grab a CoolPower RAPS44 Power Pack, Goal Zero Yeti 150 or Companion Power Pack 44Ah depending on how many amps your fan draws and how long you'd like to run it for.

G'day Adrian,

Providing you have a regulator or charge controller on the solar panel, you should have no issues charging simultaneously. 

G'day Annette,

You can use as large a sized solar panel as you like with the Engel Smart Battery Box Series 2, as long as the solar panel has an inbuilt charge controller, which most will have these days.  Hope that helps.

G'dau Greig,

I've just double checked this and I can confirm that the Smart Battery Box Series 2 comes with a 12v and 240v cable.

G'day Billy-Ray,

Yes, you absolutely can charge and discharge at the same time. Its really important to note though, if charging your Engle Smart Battery Box Series 2 with solar panels, the charge goes directly to the battery and NOT through the Smart System.  In this case, you will need to use any solar system with a regulator.

G'day Darren,

The maximum continuous power the Smart Battery Box can tolerate 300 watts, with a spike output power of 900W. So in short, no you won't be able to charge a 400-watt hour lithium bike battery with this unit.

G'day Steve,

There is both a standard cigarette style 12V plug and an Engel 12V socket, so there won't be any need to replace or remove any of the ports.

G'day John,

Yes, you can charge the Engel Smart Battery Box Series 2 using a solar panel. You'll just need to make sure your solar panel has a regulator and can connect via an Anderson plug.

G'day Tom,

We've double checked with Engel, and the Smart Battery Box Series 2 can be used with LiFePO4 batteries. The lead supplied will be able to charge all battery types used in the unit.

G'day Steve,

I've just consulted the tech experts and the Engel Smart Battery Box Series 2 doesn't have an overcharging protection mechanism so you'll need to use it with a solar regulator. Most Solar Panels have these inbuilt and attached to the back of the panel.

G'day Jeff,

Engel indicate that the Smart Battery Box Series 2 is compatible with a range of battery types: LiFePO4, Gel, Calcium, AGM or lead acid. There isn't a specific battery they suggest but a battery specialist like Battery World will be able to run you through the features of the different battery types and help you to choose the best option.

G'day Alex,

Sorry mate but I'm not entirely sure I know what you mean by externally vented or sealed? I've run it past a few of the staff and I think we'd prefer you gave us a call just so we can clarify what you're after to get you the right answer. Feel free to get in touch on 1300 914 007.

G'day Patrick,

It would depend on which battery you put into the Engel Smart Battery Box Series 2. A lead acid battery with take a different amount of time to charge than a calcium or lithium battery. Best bet would be to check the battery you choose for charge times, and to check the amperage of your 12V ports in the vehicle you're planning to charge from. 

G'day Colin,

I've given Engel a buzz to suss this out for you. They told me that the Smart Battery Box Series 2 just has the one Anderson outlet that you can use to both charge or run things from your battery but being only one outlet, you can't do both at the same time. It also doesn't come with a low voltage cut out, so will run your battery dry if you're not careful.
