Great battery, works well in my solar installation Battery was at a great price (sale) and it's working very well on my solar installation. So much better than Lead-Acid.

Quality seems really good so far Quality seems really good. I installed them in my Cub Cadet rzt s 42 and it's back to running reliably. It was due for replacing the 4x AGM batteries, but felt the $800 cost would better be used on LFP considering costs have dropped over the years. I did spend more on the eco-worth batteries, but with the discounts the cost seems well worth it. After slight modifications they fit perfect and runs great. It would be nice if more companies would start selling lithium chargers that can be set to only charge to 80% though.

DO NOT BUY FROM THEM UNLESS YOU KNOW YOURE KEEPING THE ITEM OR CAN FIX IT IF IT BREAKS DO NOT BUY FROM THEM!! Absolute farce of a company! Customer service is disgraceful. Warehouse is in Leicester but contacts are in either the US so communication is slow and nothing gets resolved within a decent timeframe. I ordered the wrong thing, rang their customer services and cancelled the order same day. Messages were not passed quick enough or to the right people and the items were delivered 2 days later (from 1hr up the road!). I wasn't home so couldn't reject the delivery which is what I was advised. I ended up paying to return the cables and controller but refused to do it tracked because that was almost as expensive as the items and now they won't refund me ANY MONEY even though they know what parcel to look out for, have all the details and the receipt but that's not good enough. I have spoken on the phone and emailed multiple people, multiple times. The solar panels are a nightmare to return as no post office/sorting office wants to hold such a big/heavy item so I ended up selling them at a loss. I refused to pay the cost of a courier with no guarantee I would get a refund as I have no faith in this company and they seem to do anything they can to get out of paying.
