After all, lithium ion can also be maintenance-free, so there’s no must schedule common battery providers.

Total, they’re nice for continuous and irregular utilization the place your cost cycles might not at all times be constant.

We use ours continuously, for charging our journey drones, aircon unit, heating water, our fridge, charging our journey laptops, our MaxxFann. To not point out fixed lighting and different minor home equipment we use all day in our campervans electrical system.

Principally, fixed and extremely variable use. And with an honest B2B and photo voltaic setup, now we have not as soon as but wanted to recharge utilizing a mains outlet, and the batteries haven’t skilled any drop in efficiency regardless of this.

Roamer Lithium Ion LiFePO4 Battery overview

We had been fairly pumped about attending to attempt these batteries.

The most recent Roamer 300SMART2 has a nominal capability of 300Ah at 12.8V, which gave the impression of precisely what we’d like.

I actually love how the upgraded BMS can steadiness all inside cells. And should you ever want extra energy, you’ll be able to simply set up 4 of those batteries in collection or parallel.

To not point out a collection of protections, together with low temperature charging.

One other element price declaring is that Roamer is now providing their second-generation batteries. 

This implies they’re extra superior when it comes to battery building and BMS system, in order that it’s appropriate with the most recent Roamer cellular app.

What number of Roamer battery sizes are there?

So, I’ve solely examined the 300ah lithium ion model, however there are literally various choices to select from.

Do not forget that all of those batteries may be mixed both in collection or parallel to generate much more energy.

  • 12V 100Ah – The smallest battery measurement is the 100 SMART2, a brilliant compact 12V 100Ah leisure battery that weighs simply 12 kg and measures 325mm L x 170mm W x 220mm H. That is nice for these with a very small sprinter van and solely must energy minor home equipment.

However the superior BMS Bluetooth on this battery solves that actual drawback.

It connects to your cell phone so you’ll be able to examine the cost degree everytime you need, in addition to how a lot energy is presently going into or popping out of the batteries.

There’s additionally different real-time data on your battery stats together with cell voltages, and you may view and edit parameters too.

To not point out that the app makes figuring out issues with the built-in alarms tremendous straightforward.

I discovered the general interface to be pretty easy and intuitive, which is one other plus.

At solely 30 kg, this 12V 300Ah battery could be very light-weight. Whereas the scale are equally minimalist: 525mm x 240mm x 220mm.

It’s been tremendous helpful to have extra energy whereas lowering the battery footprint and it’s giving us extra space for further storage!

Our outdated setup was made up of two Xplorer™ AGM batteries, which had been twice as cumbersome and 10 instances as heavy.

Not solely that, however these AGM batteries really had 70Ah much less usable energy in comparison with our new Roamer 300Ah.

Nonetheless, I do advocate guaranteeing that every one the chargers you employ are appropriate with lithium ion batteries and to configure them correctly.

One factor to notice is that, if you’re dropping this battery in, remember to examine the scale and put together accordingly. In comparison with different forms of leisure battery, like-for-like in energy they are going to be a lot smaller.

Which is a pleasant drawback to have! I simply needed to level it out as when switching out from our outdated batteries, we needed to rearrange cable lengths and area for the battery to be secured.

Relying on the dimensions, the battery gives round as much as 5000 cycles at 80% discharge, whereas the low temperature safety is nice for stopping injury when touring in additional excessive climates.

To date, I’ve had completely no drawback with charging them. We have now a 60amp Sterling B2B and it may possibly preserve the batteries absolutely topped up, even by itself. We even have 480 amps of photo voltaic which retains issues topped up, even in delicate daylight, if we aren’t shifting for a couple of days.

If on common we use 50Ah-150Ah of energy when parking up for the night time, inside 2 to three hours of driving, the batteries shall be absolutely recharged for the subsequent day. 

We’ve spent most of our time in Canada with no actual daylight, and this principally exhibits that we don’t even really want our solar energy but to maintain these batteries full!

6. Wonderful customer support

Whereas not precisely a function of the battery itself, I actually really feel that Roamer’s customer support deserves a particular shout-out.

Their staff is loopy pleasant!

As I discussed earlier, the founders are a younger entrepreneurial couple who’s additionally obsessed with campervans.

To not point out straightforward upkeep. So should you can’t be bothered to take care of spilling acids, then this lithium ion battery is for you!

Whereas Roamer batteries might not be as expensive as another lithium ion battery manufacturers, they will nonetheless be fairly costly.

Particularly should you examine them to AGM and lead-acid leisure batteries.

In case you’re on a funds and wish probably the most reasonably priced possibility, perhaps it’s best to go for an open lead acid battery.
