Lithium starter battery

The new IBS lithium starter battery is an alternative to a classic lead or AGM starter battery. Thanks to lithium technology, the 60Ah battery weighs only 6.4kg and delivers 800A cold start current (CCA). In addition, using the emergency start button on the battery, a reserve capacity for an emergency start must be switched on for 3-5 seconds, like with a booster module. Dual stands for the two Possible applications: Starter battery and capacity battery with 60Ah usable energy with a load of 100A continuous current and 180A over 30 seconds. This battery can therefore be used in the vehicle sector including 4WD, construction machinery and boats.

IBS Li-Ion battery combines a lot of power with light weight. At only 14.7kg 100Ah capacity are available, which can also be availed. Compared to an AGM battery with the same capacity, the IBS-LiIon100 weighs less than half. Since 100% capacity is usable, four times the capacity per kilogram  is available. With a 100Ah AGM battery only 50% (50Ah) can be used.
The 100A Li-Ion battery provides 150A for 40 minutes, which is an absolute top value. A lead acid battery of the same size reaches its limit after 15minutes.

Other battery sizes are available: 50Ah and 180Ah. 100Ah is the available standard size.

For technical reasons, the cell voltage in Li-Ion (LiFePO4, lithium iron phosphate) is 0.6V higher than in lead-acid batteries, which technically has an advantage since many appliances perform better such as inverters or 12V compressor fridges.

The IBS-Li-Ion 100Ah is suitable as a powerful auxiliary battery and should be installed in the vehicle interior, since this battery is equipped with a lot of power electronics called BMS. This BMS protects the battery against over- and under-voltage, overcurrent and deep discharge. The battery delivers up to 160A and is specially protected against mechanicall damage such as an accident. at -20 ° C, depending on the load, between 50% and 80% of the capacity is still available.

IBS has adapted the IBS products range for the new lithium batteries for many years. Thus, the dual battery system IBS-DBS (as of version 8.1), the IBS-DBR-Li and the new version of the IBS-DBM20A (as of version 2.7) are ideally suited for use with these high-performance batteries.

The IBS Ultra Sine Inverters 400W / 800W / 1600W deliver much more power due to the high available energy. The applications are versatile and, thanks to the large weight savings, ideally suited for camping, expedition, service and emergency vehicles.

The IBS-LiIon 160Ah / 25.6V battery is suitable for all applications where a lot of capacity in a robust design is required. House technology, trucks, truck-based expedition vehicles, sailing and motor yachts, telecom with solar-powered repeater and transmitter stations are some of the possible applications. This "Big Capacity Battery" is built as a 24V battery and is combined with 24V chargers (lithium capable) or inverters such as the IBS 24V Ultra Sine 400W / 800W / 1600W and Grid Tie Inverter.

The large capacity of 4.1kWh is fully usable and can be operated with up to 4 batteries connected in parallel, which corresponds to a total capacity of 16.4kWh. In this constellation, up to 16KW power can be operated.

The battery is provided in a robust metal box with a weight of 48 kg with robust handles, the plus and minus connections are M10 screws.

For Telecom, 2 batteries can be connected in series without an additional balancer to operate 48V systems. Up to 4 batteries can be connected in series. Before switching in series, all batteries must be charged to 100% with the same charger; when switching in series, the voltage of the batteries must not differ by more than 50mV.

16.4kWh from 4 batteries connected in parallel corresponds roughly to the battery capacity of a compact electric vehicle.

With optimal charging (mains charger or solar system) and good energy monitoring, 5000 cycles with DOD 50% and 3500 cycles with DOD 70% are achieved. If the system is well dimensioned and a charging cycle per day according to the DOD discharge level mentioned above, a service life of Achieved 9-13 years. Compared to stationary lead-acid batteries, the costs of this technology are at least half as expensive (compared to the converted energy). Lithium ion (LiFePO4) batteries are not subject to any risk of sulfation, even an occasional deep discharge does not offend the battery. If the battery is overcharged or deeply discharged, the integrated BMS (battery management system) kicks in and switches the battery off. In this case, the battery must be woken up with a charger (which also delivers a charging current if no battery is visible).

The optimal operating temperature is 0 ° C to 40 ° C. At cold operating temperatures, the charging current should be a maximum of 0.2-0.5C. In telecom systems in the desert, the temperature must be limited to 40 ° C, depending on the maximum possible charging current.
