Excellent customer service support for the SVB Marine lithium battery LiFePO4 12V 280Ah The battery arrived clean and quickly (at least until customs clearance) and fully meets the promises. Unfortunately, the customs agency used had massive IT problems with their (apparently new) electronic customs clearance system! And we "got" to experience this firsthand!! Thanks to the excellent help from SVB customer service and numerous emails and phone calls, the situation was finally resolved satisfactorily with the customs agent after an intense week of back and forth. The battery is absolutely top-notch, and I can recommend it 100%.

Product details

Batterie Spezifikationen

This powerful marine lithium battery (LiFePO4) from ECO WORTHY features a capacity of 280 Ah and is ideal for use on boats and in motorhomes, on campsites, in off-grid wind or solar systems, as an emergency power supply and in other energy-intensive applications. Thanks to its mechanical and circuit design, it can be used as a spare or drop-in battery, provided the existing charging system on board is suitable for the requirements of lithium batteries.

The marine lithium battery is equipped with an integrated, innovative battery management system (BMS), which effectively protects the battery against overvoltage, short circuits, overloading due to excessive charging or discharging currents, excessive temperatures and undervoltage. To protect the cells, the BMS automatically interrupts the charging process if the charging temperature drops below 0 °C. Once the temperature rises above 0 °C the charging process continues.

Maximum discharge depth, unbeatable long life

As well as weighing just 29.0 kg, these lithium batteries boast a remarkable 3000 charge/discharge cycles with a depth of discharge of up to 80 %. With proper use, a service life of up to 15 years can be expected, which is three times that of a conventional lead-acid battery.

Capacity expansion

Up to four batteries can be connected in parallel if a larger battery capacity is required. Up to 4 of these batteries can also be connected in series, thus enabling them to be used in 24 V (2 units), 36 V (3 units) or 48 V (4 units) wiring systems.

I can't yet give an assessment of the lifespan and quality, as I only installed the battery in August.
The weight is easy to handle. I haven't found anything comparable online at a cheaper price.

Lithium iron phosphate batteries on boats and yachts - properties, special features and use
The lithium iron phosphate battery (LiFePO4 battery) or LFP battery, is currently the best in the battery sector. A basic distinction is made between conventional lithium-ion batteries and the newer generation of batteries, lithium iron phosphate batteries. The terms lithium-ion battery and lithium iron phosphate battery are often used interchangeably in everyday language. However, this generalisation is not correct when comparing the two types of battery directly and with regard to their chemical and technical structure. Both battery types have decisive differences. In this guide, we explain what these are in detail, which battery type has which advantages and many other details, especially about lithium iron phosphate batteries.
