Marine lithium batteries from ECO-WORTHY LiFePO4 - powerful, safe and versatile
The powerful LiFePO4 lithium batteries from the ECO-WORTHY brand are available in various capacities - 20Ah, 30Ah, 50Ah and 100Ah - and are ideal as a supply battery for use on boats, in motorhomes, on campsites, in off-grid solar or wind systems and as an emergency power supply for many other energy-intensive applications.
Thanks to their mechanical and circuit design, the batteries can be used as spare or replacement batteries (drop-in), provided the existing charging system is suitable for lithium batteries.
Your advantages at a glance - compared to AGM or lead-acid batteries
- Deeper discharge possible:
LiFePO4 batteries allow a depth of discharge of up to 90 %, while AGM or lead-acid batteries should usually only be discharged to 50 % - this means more usable capacity with the same rated power. - Longer service life:
A service life of approx. 10 years when used properly - compared to only approx. 3 years for conventional batteries. - Extremely high cycle stability:
Up to 4000 charge/discharge cycles at 80% depth of discharge - conventional AGM or lead-acid batteries only achieve 200 to 500 cycles. - Significantly lower weight:
Depending on the model, LiFePO4 batteries are over 70% lighter than comparable AGM or lead-acid variants - ideal for mobile applications, e.g. on boats or in motorhomes. - More compact design:
Despite identical capacity, the dimensions are significantly smaller, which saves space and makes installation more flexible.
To compare the weights:
Integrated battery management system (BMS)
All models are equipped with an integrated, innovative BMS that reliably protects the battery from overvoltage, short circuits, overloads, undervoltage and excessive temperatures. At temperatures below 0 °C, the charging process is automatically interrupted and only resumed when the temperature is above 0 °C.
Maximum service life and cycle stability
The ECO-WORTHY LiFePO4 batteries offer up to 4000 charge/discharge cycles at 80% depth of discharge and a service life of up to 10 years - this corresponds to three times that of a classic lead-acid battery.
High charging speed
The batteries reach up to 80% of their capacity within one hour, making them ideal for situations with limited charging time.
Flexible capacity expansion
All variants can be connected in series (up to 4 units for 48 V) or parallel (max. 4 units recommended) - ideal for flexible adaptation to energy requirements.
Note: To ensure safe operation, we recommend installing a main fuse (ANL or MEGA) as close as possible to the positive pole (max. 20 cm away).
Various application possibilities
Whether for UPS systems, lighting, televisions, speakers, electric robots, coffee machines, refrigerators, air conditioners or heating systems - these lithium batteries are very versatile.
