LiFePO4 Li-ion batteries for your boat and other mobile applications

Why LifePO4?

Technology going FWD and comparing with conventional batteries the Li-ion LiFePO4 opens completely new horizons in energy storage and usability for mobile vehicles – faster charge/discharge cycles, higher safe usable energy qty (up to 80% DOD), while comparing to conventional AGM safe 35% DOD or up to 55% DOD for specialized deep cycle. Assuming you don’t exceed 80% “DOD”, Li-ion LiFePO4 will serve you up to 4000 cycles. Indicated cycles are not the limit, it is the number where Li-ion LiFePO4 still has 80% of it’s initial capacity. If you use up to 50% of DOD, you double the cycles.

What can be powered by Li-ion?

the market standard 12V & 100 Ah Li-ion LiFePO4, the weight of only 12 Kg, can easily deliver 80% i.e. 80Ah of capacity without any harm to long life. That equals to 12V / 150 Ah and 45kg-48kg weight deep cycle AGM, that delivers 55% of it’s capacity. The myth is the AGM can deliver 100% capacity and not damage the lifetime and performance, where declarative cycle count is up to 400 cycles. We don’t think it is achievable in real life. We made a test by killing 6 EA AGM batteries (known maker) 130Ah and 160 Ah. The Battery managed to take the hit of only 10 cycles of 35% DOD. The cost of experiment was 2k+ euro and we have ground to stand for our words. Experiment attendees were twin 2x 160Ah, and 2x 130 Ah AGM batteries separately, they provided power to 2500W Mastervolt pure sin wave inverter, that was feeding electric grill of 230V / 2.1 kW power. The system had support of Cummins 12V / 80A generator all the time. AGM cannot do the job the Li-ion LiFePO4 can.

What is being untold by AGM resellers?

We call it like “small letters on the other side of instruction”, that nobody reads. Majority of buyers are pleased by declarative sellers wording the battery is of known brand, known maker and all should be good. However, what is it all about? – that secret is where AGM and other led acid batteries demonstrate less capacity than declared, when the battery of say 100 Ah capacity is being loaded and power consumed faster than in 20 h. Why 20h? – it is the standard time all conventional battery makers measure battery capacity Ah at +20 C . What will happen if we consume our stored battery capacity faster? say electric anchor consuming 15A – you don’t have 100 Ah energy capacity, you have up to 35% less, if your consumption duration is 5h and 50% less if you consume in under 3h! That is the basics of chemistry of conventional AGM/GEL batteries, that is not delivered to the buyer. Low temperatures is another killing factor, and the user is easily mistaken, seeing declarative figures of AGM, where 100 Ah is available with condition 20h, at 20C ambient. On other hand if power consumed is not significant, say 1A, 100Ah GEL/AGM battery will deliver up to +20% of declared capacity. Again, it is chemistry performance. Li-ion LiFePO4 batteries has no capacity “Ah” fluctuation, dependent on power consumed.

100 Ah 12V/24V and higher capacity batteries has Bluetooth BMS as standard, to monitor your battery parameters and control your charge/discharge:


How does Li-ion starter battery works?

We requested a specific #V12150T to be manufactured, according our spec’s and it worked. We replaced dead AGM 75 Ah theoretical, 50Ah pactical , but dead anyway, to Li-ion 150Ah with 200A continuous 30 min, and 450A peak 3sec. Watch the result in Video
