ECO-WORTHY 50Ah 12.8V Lithium Battery Emergency Power Backup Rechargeable LiFePO4 Lithium Iron Phosphate with 3000+ Deep Cycles and BMS Protection, Perfect forRV, Boat, Marine, Solar Panel System

I now have a total of four of these batteries connected in series for use with Victron 48 volt charge controllers and around 2kW of solar panels, This drives a 48 volt victron 5KVA inverter and to date have performed flawlessly. I can confirm that the 280 amp hour capacity looks to be as expected judging by the charged and discharged energy statistics from the system and the voltage profiles against the percentage charge look spot on for the lithium iron phosphate technology used. So far working flawlessly and no temperature issues under heavy charging or discharging currents.

One of my pair of Lead Acid batteries died and got smelly, swollen and hot on the way over to France at school holidays in our campervan so we needed to replace it. I looked at the options and as the cost has come down and these had good reviews I thought I'd give it a go. 300 charge cycle for LA v 6000 for lithium seemed like it was now worth it and it had a decent discount as well. I removed the other LA and fitted this. MTTP was easy to switch over as was the DC DC and so far works like a dream. The other ones have always been prone to discharge with the fridge running and the MTTP would cut off to try to protect them this is much less of a problem with this one as you get a constant voltage. Well made and it's not light but I think it's around the same weight as the old pair but with more 80 ah more juice.

The unit has done what I expected it to do, however even with the built-in BMS, I could not get their bluetooth app to work. Customer services then told me this model doesn't come with bluetooth capability, even though their website says it does. Suggest you check before buying as their customer service is by email and not phone and they are slow to respond to you.

Excellant product. Used for our electric outboard and it last the day no problem. Small size and very light compared to conventional batteries

This battery is fantastic 4 x 280 amp gives enough power to stay off grids in our van conversion.The advise and aftercare has been of the best , clear advice, all backed by a great warranty.I would recommend both battery’s and the companies products.Many ThanksKeith @ Made to Roam

Leisure batteries are coming a long way recently, this is a fantastic battery. Wish I waited a few weks and could have saved a fair bit of money but happy with the battery. Well built, not too heavy for the capacity, will keep the campervan running happily.

I had been buying and using deep cycle lead acid batteries for powering portable ham radio stations. They don't last too long and are heavy.. This battery is light, and has all the power I need and no danger of acid spills. I delayed this review so I could give it a testing. Over the moon with it and highly recommend these batteries

I bought 2 batteries in such higher prices even before I have used them to power my heater.So far I am not sure if they could work on my my 3000w heaters, until I have got the inverter. If it does not work, I would return these batteries
