After more than 3 years of research, development and testing, R&J Batteries is proud to introduce the REDMAX RMBC1220 Smart Battery Charger, the flagship product in the REDMAX range. Designed to deliver efficiency, versatility and long term reliability, the RMBC1220 was developed to address a gap in the market for a premium quality, high performance charger at a competitive price.

"The REDMAX RMBC1220 development project started 3 years ago with a list of ‘must have’ design features. We are genuinely excited to introduce the final product which satisfies all of these requirements and also addresses the critical failure points of most other chargers. Combined with the attractive design and simple operation, this charger is fantastic value for money.” As described by Tim Lennon, Product & Technical Manager at R&J Batteries

At the heart of the RMBC1220 is its fanless design and high efficiency switchmode technology. Rather than relying on a cooling fan, which can eventually fail, the charger uses its extruded aluminium case to dissipate heat from the internal components which provides quiet operation while helping maximise durability and longevity. The charger is also IP65 rated, which means it is suited to workshop and garage environments.

The RMBC1220 uses microprocessor controlled multistage charging to intelligently manage the charging process for each battery type. It supports 12V lead acid batteries as well as lithium iron phosphate batteries, with selectable charging currents of 1A, 3A, 7A, 12A or 20A.

It’s seven stage charging process includes BMS Wake Up for Lithium batteries, Initialise & Soft Start, Bulk, Absorb, Analysis, Recondition/Equalise and Float depending on the battery type. The charger also features a Power Supply Mode with adjustable current to help stabilise vehicle system voltage during diagnosis and testing.

Built for the demands of professional and home workshops, the RMBC1220 combines advanced charging technology with an innovative, practical design. Backed by a 5-year warranty and competitive pricing, the REDMAX RMBC1220 is a versatile addition to any garage or workshop.
