Victron Energy Lithium SuperPack 12.8V/200Ah

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 case of deep discharge, overcharge, or low or high temperature. Please note that this battery does not have Bluetooth or a charge level indicator.

Protected from 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, the operating life is slightly increased if the battery is only partially charged instead of 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 when 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 charging cycle (discharging from 100% to 0% and recharging to 100%) of an average lead-acid battery is approximately 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 inefficient especially when the 80% mark of the state of charge has been reached, leading to an energy efficiency of only 50%. This value is even lower for solar systems, since 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 utilization level of 90%, even when it is in a flat state of discharge.

Can be connected in parallel.
