Indicates in 5 steps via 3 LEDs the actual charging condition during operation of an 12 V accumulators. Thus it is easier to control the accumulator and a total discharge can be prevented. In addition it is checked whether the accumulator is in order and it receives the full charging voltage from the battery charger. (If the Battery guard is connected during charging of the battery.) The Battery guard is designed to monitor a battery in a closed, active circuit.Very low consumption of less than 4.9 mA!

The VOTRONIC units Battery Protector 40 and Battery Protector 100 are connected between supply battery and consumers, and they are suitable for all types and brands of lead batteries (acid, gel, AGM). The units protect the battery from dangerous total discharge and the consumers and equipment from undervoltage and overvoltage. Apart from that, they can be used as remote-controlled battery main switch by means of an external switch. Switching current 40 A, short-time overload up to 60 A is admissible, display of the switching state is visible from outside EMERGENCY ON function by switch at the unit; remote control is possible by external switch Automatic reset, as soon as the battery voltage is again in the normal range (charging) Separate sensor cable and switching thresholds with hysteresis and timer function for trouble-free operation Bi-stable power relay, very low own consumption: less than 3 mA (according to EN 13976) No own consumption after disconnection by external switch, such as remote control as battery main switch Solid terminal screws for battery and load cable cross sections up to 10 mm² Execution “Motor” with higher disconnection thresholds keeps the starting ability of intervention vehicles with only one battery circuit according to DIN EN 1789

The Victron Energy Battery Balancer MPN BBA000100100 is a charge equalizer for 24V and 48V battery banks. It equalizes the charge level of two serially connected 12V batteries or several parallely connected battery strings. This prevents damages on the battery caused by imbalanced charging levels. The problem: The life-span of an expensive battery bank can be reduced drastically by imbalanced charge levelsA battery with slightly increased leakage current within a 24V or 48V bank consisting of several serially/parallely connected batteries may cause an insufficient charging of parallely connected batteries or an overload of serially connected ones. Moreover new cells or batteries should have the same charge level when connected in series. Small differences can be smoothed out during constant voltage phase or equalizing charge. Bigger differences however lead to damages. Reason for that is excessive gas development through an overload (batteries with higher initial charge) and sulfating caused by insufficient charging (batteries with lower initial charge). The solution: battery balancing with the Victron Battery BalancerThe battery balancer equalizes the charge level of two serially connected 12V batteries or of several parallely connected battery strings. If the charging voltage of a 24V-system exceeds 27.3V the battery balancer compares the charge level of both batteries (serial). It drains power (up to 0.7A) from the battery (or battery string) with the higher voltage. The consequent difference between the charging currents leads to a balanced charge level of all connected batteries or battery strings.If necessary several battery balancers can be connected parallely.A 48V battery bank can be equalized with 3 battery balancers.

Lithium-ion batteries in particular have almost no capacity left when they are discharged to the point of shutdown due to low voltage After shutdown due to low voltage, the reserve capacity of a lithium-ion battery is approximately 1 ah per 1000 ah of battery capacity. The battery will be damaged if the remaining reserve capacity is drawn from the battery. For example, a residual current of 10 ma can damage a 200 ah battery if the system is left in a discharged state for over 8 days intelligent: Monitoring the midpoint voltage One damaged cell or battery can destroy an entire large, expensive battery bank.

This battery saver protects your car battery from total discharge by switching off consumers such as ice boxes, heaters, radios + television sets, etc. in time. It switches on again automatically after return of the normal voltage. The interrupting voltage is adjustable: approx. 10.4 - 13.3 V. Important installation instructions, please note! Depending on the load the module heats up. The heat is dissipated from the aluminum plate at the bottom of the module. Under certain circumstances it must be mounted on a cooling surface according to installation instructions. It is important that the module is fixed with 4 M3 screws (or 2.9mm metal screws) on the cooling surface. This may be the back wall of a metal casing. The aluminum plate on the bottom of the module must not bend, do not use larger screws and do not drill larger holes. The screw heads must rest on the plate of the module, rather than on the plastic edge of the module! During assembly, the module should not be curled up (if the ground is not flat). The reason: on the inside of the aluminum base of the module the thin insulating layer are directly soldered on the electronic SMD components. When the aluminum floor of the module curls up, the joints and the module start loosen and the module is defective. Please ensure that the maximum specified temperature (as specified in the module's description) is not exceeded. Otherwise apply a larger cooling plate.
