SafeCharge™ Current limiter is exclusive and patented by Volthium, and it is revolutionizing the recreational vehicle, boating, service vehicles, and heavy-duty vehicle industries.
Thanks to the intelligent management of charging from the alternator, it eliminates the need for a DC-DC module or a BIM isolator in your installation!
SafeCharge™ Current Limiter in a nutshell:
-
The combination of the advantages of DC-DC with the benefits of a lithium contactor with an algorithm: intermittent intense charging and resting periods (15min/20min).
-
Retains the original Boost/Combine feature available in RVs.
-
Allows for a single battery circuit for deep discharge and starting.
-
Essential for the Class 8 trucking industry and commercial fishing.
Batteries compatible with SafeCharge™ current limiter
There are only two batteries equipped with a BMS compatible with SafeCharge™ technology on the market!
These are Volthium’s 12V 100 Pro 2 and NAPA’s 12V 120Ah.
Indeed, the American automotive giant has chosen to trust Volthium for the development of its brand-new lithium battery line, which was launched in June 2025.
These two models have been designed by Volthium to meet the specific needs of recreational vehicles and motorboats. The challenges related to installing lithium batteries—whether cost, time, or complexity—were barriers for our installer partners and customers. Our exclusive SafeCharge™ technology removes these barriers in a revolutionary way.
SafeCharge™ Technology Revolutionizes the Industry
SafeCharge™ technology enables the easy, fast, and cost-effective integration of lithium batteries.
The major change: it is no longer necessary to add a DC-DC, a costly maneuver in both hardware and installation time.
Another advantage, especially appreciated by boat owners, is that using the SafeCharge™ current regulator allows the engine to start with a dual-use battery like the Volthium 12V 100Ah Pro 2 or the NAPA 12V 120Ah. This would not be possible with a DC-DC because the latter prevents current from flowing from the dual-use battery to the engine, a crucial function for providing the necessary energy to start the motor.
The SafeCharge™ regulator alone prevents many potential problems: alternator overheating, wiring failures, and unwanted circuit breaker trips. It adapts perfectly to the electrical characteristics of the boat or vehicle it is integrated into.
Simplicity at its best, signed Volthium!
Highly anticipated by motorized vehicle owners, SafeCharge™ technology finally makes it possible to safely and easily integrate lithium batteries into existing electrical systems.
Its advantages are undeniable:
-
Eliminates the need for a traditional DC-DC regulator
-
Reduces installation costs
-
Reduces labor time
-
Reduces the risks of improper configuration.
It does all this while effectively protecting against current overcharging!
For the user with limited time, the ease of installation of batteries incorporating SafeCharge™ technology is another attractive advantage, as access to a certified technician is not always guaranteed when needed, especially during peak periods. We see this every year: motivated by better weather, RVers and boaters all want to have their equipment installed at the same time, particularly in the spring.
A true innovation, the SafeCharge™ regulator represents a ready-to-use solution developed to meet the needs of anyone looking to optimize their electrical system without compromising on safety or performance.
By bringing this innovation to market, Volthium, true to its mission, makes the transition to lithium more accessible, reliable, and better suited to today’s realities.
