Volthium, based in Quebec, is dedicated to making high-end lithium-ion batteries accessible for mainstream use in battery banks, not only for RVs and boats but also for larger off-grid systems. They offer various battery group sizes as drop-in replacements for lead-acid, as well as modular rackmount batteries adaptable to any need.
The Volthium 51.2-200-R and 51.2-200-R-H are part of their Rack Mount series, providing 48 Volt 200 Ah (10.24 kWh) of stored energy. Designed for standard 19″ racks, these 4U units can be installed in racks from brands like Tripp Lite or StarTech.
The option with a built-in heater ensures safe operation and charging down to -30C (-22F) without user intervention, drawing a charge current of 5 Amp when heating.
Stackable up to 16 units in parallel, these batteries create an integrated battery bank with auto-balancing capabilities. With regular studs for easy connection and VE.Can bus integration for direct communication with Victron GX equipment, additional battery monitoring is unnecessary.
Volthium lithium-ion batteries are true deep-cycle batteries, featuring a built-in BMS for protection against over- and under-charge, low Voltage disconnect, over-current, and automatic cell balancing. Certified to UL9540A and CSA-listed, these batteries are safe for both commercial and residential use.
Charge settings are straightforward, with options for bulk/absorb, absorb time, and discharge rates. The LiFePO4 chemistry ensures stability and safety, allowing for indoor mounting in any orientation without off-gassing concerns. With their ability to be discharged to 100% DOD and their longevity, Volthium batteries offer a reliable alternative to lead-acid systems.
