Ecotree Lithium - The Lithium Battery Specialists Reviews 

Absolutely brilliant, we had an issue with our van battery not even the lithium we bought from them and they told us what to do to solve it. Lithium battery brilliant, after sales absolutely amazing. Thank you

2.5 years down the line. 2 x 110Ah battery’s still going strong. Quite a lot of day grid and about 500 night in total. Since then fitted 2 in a friends new van. My van now sold as down sizing so will be looking for an under seat battery. Easy to speak to customer service.

Apparently they are good batteries, but actually getting to talk to someone pre-sale, with £500 ready to part with, proved nigh-on impossible.

When I finally did talk to someone, his opening gambit was to try and tell me they had tried to call back, and when I begged to differ, as I had received no call - despite having given 2 numbers to call & offered WhatsApp voice call or mobile - started to argue with me, 'The Customer'.
Totally unprofessional pre-sales process, if I can buy the [good] product elsewhere, I will, otherwise, it's a different supplier for me.

My leisure battery (lead acid 12V 110Ah) had failed completely in my DIY van conversion. I'd done some research and decided that a lithium battery would be a much better option. Unfortunately, being the kind of person I am, I neglected to do anything about it until the day before I was due to go on a trip. I rang Eco Tree Lithium and everyone was so helpful, even though I didn't have the required information for them to know what would be suitable. I'm fairly local and they were happy take a look. I got there just an hour before they closed and they checked everything out, removed my old lead acid battery and fitted a 12v 105AH LiFePO4 with Bluetooth monitoring. Everything was explained clearly and I was also given some advice on future improvements I could make to
my solar and split charging systems to get the most of the new battery. Definitely recommend!

I have been testing my Eco Tree 216Ah lifpo4 battery for 2 years now and can with hand on heart say,
It has been the best purchase I have made for my self built camper van. still charging and powering my whole 4 berth van like I bought it yesterday. Thank you so much Eco tree I fully recommend your products.

I live 24/7 in my converted camper van and I had the 230AH underseat LiFePO4 Lithium leisure battery fitted one year ago. It has performed fantastically, kept my heater and fridge performing in cold temperatures, with the accompanying app it’s easy to see your power consumptions and available power remaining. The service when fitted was excellent by the team down at Oaktree/Ecotree, they are people who understand the needs of motorhomers and campervanners and are in touch with the latest evolving tech for us. They’ve also done some other fitting work for my van and again the work is of a high standard. Total peace of mind 5*

I bought 2 batteries from Eco tree and waited a year before I wrote a review and to put the batteries through real life uses. I Both batteries have performed flawlessly and have made living in my van much more comfortable. The charge quicker than my last wet batteries even with the same solar, When I use 240V Microwave it works as it was hooked up to mains. I have had to call Eco tree twice to verify my settings, Both times they answer the phones straight away and talked me through it step by step and even called my back 2 weeks later to make sure all was working okay. Highly recommended company and batteries.

Can’t speak highly enough of the company & service!

They went out of there way to help me with a problem I had with my battery that was a fault of my own not there’s.

Wouldn’t think twice about buy from them again

Happy customer.

When my old AGM leisure batteries started to let me down shortly before a trip away I contacted Rob as we had previously brought our motorhome from Oaktree for some advice. He offered a good advice on which solution might be right for me, replace the AGM's or lithium with no pressure. I opted to upgrade to lithium and Rob with help from Gary and Richard managed to fit me in before my planned trip and fitted two new lithium batteries. The performance and recharge rate is worlds apart from the AGM's so looking good so far. Thanks for the great service and advice.

Been in contact with Richard a few times now and he has helped me so much, understanding how Victron smart chargers work with the lithium batteries and what the settings should be and why. Always helpful and understanding, speaking in simple terms so I can understand and not making me feel like I was stupid.

I now feel so much more confident regarding the electrical system.

The product and the help from the people behind the company.

Whenever I have called up for support or advice I have been given the very best in customer service.

We have been using their batteries in our ocean rowing boats since 2019 and have never had an issue that has not come from user error!!

We have also recommended them to several other crews, all of whom have had nothing but good things to say about their experience.

Purchased two batteries and required aftersales assistance. Issues resolved promptly and effectively.

I got a lithium battery fitted, Rob was incredibly helpful and even managed to come in and squeeze me in a slot out of hours so i could get my battery in before i headed away on a last minute trip. Battery and everything working perfectly. thanks rob!

After months of searching the common denominator in happy lithium campers was Ecotree. We enquired as to what was needed booked an install date and all went as planned, Great Service.
Removed 2 x 95AH AGM's and installed 1 x 230AH under seat and what a difference. Tested over a few nights and days TV, Fridge, Heating (usually kills our batteries), Lighting etc. all on (more than usual use) to put the battery through its paces and performed better than expected, really happy THANK YOU Ecotree

I hadn't realised that van electrics can be a minefield particularly if you are chasing that off grid holy grail! Ecotree are much more than a supplier of fine lithium batteries, they really do understand the sometimes complex and varied requirements that us camper owners have and have the time and patience to talk things through to ensure that you get the best performance from your system. Since we live in the far west of Cornwall I was apprehensive about buying something from a supplier 300 miles away in case something went wrong! If we lived closer I would have got them to do the install with so much money at stake and only having a basic knowledge of electrics! However my fears were totally unfounded. Dave talked me through the install including a new charge controller (badly advised on my first one!), partial rewire and the customised bluetooth settings. Must admit that I feel pleased that i have done the install myself and consequently have a much better understanding of how it all works and feel confident that (with Daves help) I can take on future improvements when we have saved up a bit more! Can't recommend them enough.

From the first point of contact we knew Ecotree was the way to go when it came to upgrading to Lithium.

Rob couldn't have been more accommodating to our needs, helping us figure out the perfect set up for our converted sprinter van that we live in full time.

We went through the pros and cons of many different sized batteries, inverters, chargers etc until we struck the perfect combination of size, weight, cost and our day to day needs.

However this was just the beginning; The guys in the workshop were brilliant. Attention to detail during the whole process was second to none and no corners were cut when it came to setting everything up to give us optimal efficiency.

After discussions with Rob we ended up replacing our 2 x 220AH AGM batteries (which weighed 122kg!) with one of the newer 230AH Ecotree underseat Lithium batteries weighing in at just 24kg! Not only was the weight saving a huge plus, but so was the space we gained.

The efficiency of the Lithium battery allowed us to cut down on the amount of power we had in the van, as near enough all of it is useable compared to previously only being able to use 50% of the AGM batteries.

Due to the battery capacity being lower, this meant that charging times became quicker too. All in all, a far more efficient system.

In the end we upgraded our batteries, Inverter, Solar controller, roof fan and even had a hook up installed with a smart charger which resulted in us driving away with a completely overhauled system, and the confidence and peace of mind that everything now worked as it should, and then some!

A huge thank you again to Rob for his attentiveness, and all the guys that spent the time working on our van, dealing with the bombardment of questions me and Amy kept firing their way.

We cannot praise Ecotree highly enough, and if you're looking at upgrading your batteries... Look no further.

When I decided to change our auxilliary motorhome battery to Lithium I filled out a web form asking about charging from the existing motorhome systems. Rob called me to discuss my needs and suggested a battery to suit my setup / usage. He also asked Rich to call and discuss how I may need to alter my charge setup for best effect. Both such kowledgable people. Rich was so helpful in describing my needs that I was able to plan the changes easily with his help.
Then the cherry on the cake, Paul actually dropped by to deliver a battery for us as he was passing near us!!

All I wanted was a few questions amswered and they exceeded expectations. My upgraded system was tested this weekend and worked fantastically. Thanks to you and your team Rob... Truly amazing..

Have done some reasearch on upgrading my electrical system in my motorhome so I could camp off grid in winter without the fear of running out of power I sent Eco Tree an online enquiry. That evening I received a call from Rob who went through in great detail my requirements and gave me their recomendations without trying to get me to send more money. I booked with them to get the upgrade done and they had the vehicle all day, I was able to see the work being carried out and speaking with Richard to get a better understanding of the install. Once complete they uploaded the Apps onto my phone and explained how to use the system. I was very pleased when I picked up the bill as it was £300 lower than the estimate. Thank you Rob and your team for a first rate experience.

Just bought 2 x 100ah lithium heated and Bluetooth model.
Also 2 x 42amp.
Wow the batteries are so much lighter. 6 year guarantee. Peace of mind. I need good power for my mobility scooters Had nothing but trouble with gel batteries so decided to buy some lithium. After some research I found eco tree battery's. Uk company too.
Highly recommend you try these batteries out. Dean from Leeds

Purchased an ecotree battery was having trouble getting Bluetooth to work .Contacted Ecotree for some advice ,On the same day I had a missed call ,answer machine message and because he failed to contact me finally a text message with advice .Still struggling to sort Rob rang me with more advice and assured me we would get this sorted even spoke to me on a Saturday tea time .Needless to say problem solved which by the way was more to do with me not being too tech savvy.All I can say is these guys go above and beyond with customer service what great company Thanks Rob and team
