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.

Second-generation IBS Li-Ion batteries combine high performance with low weight. At just 11.2 kg, they offer 105 Ah of usable capacity. Compared to an AGM battery of the same capacity, the IBS-LiIon100 weighs less than half. Since 100% of the capacity is usable, four times the capacity per kilogram is available. With a 100 Ah AGM battery, only 50% (50 Ah) can be used.

Other battery sizes are 60 Ah and 210 Ah. 105 Ah is the standard size available.

For technical reasons, the cell voltage of Li-Ion (LiFePO4, lithium iron phosphate) is 0.6 V higher than that of lead-acid batteries, which is a technical advantage since many devices such as inverters or 12 V compressor refrigerators deliver higher performance.

The IBS-LiIon100 is suitable as a high-performance auxiliary battery and should be installed in the vehicle interior, as this battery is equipped with extensive power electronics (BMS). This BMS protects the battery against overvoltage, undervoltage, overcurrent, and deep discharge. The battery delivers up to 160A and briefly 200A. To generate more power, the batteries can be connected in series or parallel. The battery is specially protected against mechanical damage, such as in an accident.

IBS has been adapting its product range to the new lithium batteries for many years. The IBS-DBS dual battery system (version 8.1 and higher), the IBS-DBR-Li, and the new version of the IBS-DBM20A (version 2.7 and higher) are therefore ideally suited for use with these high-performance batteries.

The IBS Ultra Sine Inverters 400W/800W/1600W deliver significantly more power thanks to the high available energy. The applications are diverse and, thanks to the significant weight savings, are ideal for camping, expedition, service, and emergency vehicle applications.

IBS lithium batteries equipped with Bluetooth functionality can be monitored using the "IBS smart" app.

Battery voltage, battery current, temperature, and charge cycles are displayed. The batteries can be turned on and off via the app.

The following batteries (with Bluetooth functionality) are managed in the IBS smart app:

• 100AhBT
• 102AhBT
• 102AhABT
• 105AhBT
• 105AhABT
• 210AhBT

The "IBS smart" app monitors and controls other IBS products:

• IBS-DBR200BT
• IBS-DBR210BT
• IBS-DBM20ABT (in market launch)
• IBS-DBM20ASBT (in market launch)
• IBS-DBM30ABT (en développement)
• IBS-DBM30ASBT (en développement)

The IBS-LiIon 160Ah / 25.6V and 90Ah/51.2V 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/48V chargers (lithium capable) or IBS 3kW or 5kW Inverter or Grid Tie Inverter.

The large capacity of 4.1kWh or 4.7kWh is fully usable and can be operated with up to 4 batteries connected in parallel, which corresponds to a total capacity of 16.4kWh/18.8kWh. 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/18.8kWh 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.
