Victron Energy Lithium SuperPack

12.8V Lithium SuperPack batteries (without Bluetooth). Integrated BMS and safety switch. The SuperPack batteries are extremely easy to install and no additional components are required. The internal switch disconnects the batteries in the event of deep discharge, overcharging or too low or high temperatures. Please note that this battery does not have Bluetooth or a state of charge indicator.

Protected against improper use. A lead-acid battery will fail prematurely due to sulphation in the following cases: if it is used for a long time in an insufficiently charged state (e.g. the battery is rarely or never fully charged) or if it is left in a partially discharged or worse, fully discharged state. A lithium-ion battery does not need to be fully charged. In fact, life is slightly increased if the battery is only partially charged rather than fully charged. This is a significant advantage of lithium-ion batteries compared to lead-acid batteries. The SuperPack batteries interrupt the charging or discharging current if the maximum nominal values are exceeded.

Efficient. In many applications (especially off-grid solar systems), energy efficiency can be crucial. The energy efficiency of a charge cycle (discharge from 100% to 0% and recharge to 100%) of an average lead-acid battery is around 80%. The energy efficiency of a charging cycle of a lithium-ion battery, on the other hand, is 92%. The charging process of a lead-acid battery becomes particularly inefficient when the 80% brand of the state of charge is reached, resulting in an energy efficiency of only 50%. This value is even lower for solar systems, as energy reserves are required for several days (the battery operates at a state of charge between 70% and 100%). A lithium-ion battery, on the other hand, still achieves an energy utilisation rate of 90% even in a flat state of discharge.

Can be connected in parallel.
