Lithium-ion batteries

Every Bliss Mobil unit is equipped with one or two battery packs, each of them consisting of eight cells in series. The lithium-ion batteries are maintenance free, safe and can store large amounts of energy. Each battery pack represents a capacity of 400Ah (over 10 kWh) on 24 Volt.

A double battery pack comes standard in the 20, 18, 16 and 15 foot models and puts 800Ah (over 20 kWh) on 24 Volt at your disposal. The battery packs are installed in parallel and function completely independently. There is no interdependency between the battery packs.

The unique characteristic of the lithium-ion batteries is that they can be discharged to up to 100% of their nominal capacity. As such, an overwhelming amount of energy is available. A Battery Management System (BMS) and various independently functioning protection mechanisms are installed on different layers, ensuring easy, safe and durable battery operation.

The lithium-ion batteries can be discharged up to 100% versus 30-50% for conventional lead acid batteries. Where lead acid batteries will last anywhere between 500 and 1000 cycles, a well-protected and handled Lithium-ion battery pack may achieve upwards of 5000 cycles. Another advantage is that when charging almost no energy is lost.

Lithium-ion batteries show a flat discharge curve. This means they can still deliver their full capacity even when discharged at high currents, Lithium-ion batteries are also easy to store since they have a low self-discharge rate, meaning they hardly lose any charge when switched off and stored properly.
