REC offers several options for BMS applications from 12V to 800V, using many of the battery chemistries available today. To explore options for your configuration just select the product that closest matches your application to build up a semi-custom system for your application. Not quite sure how to proceed? Just fill out this form with as much info as possible and we will help put together a system for you.
For single BMS 4S applications with less than 1,000 Ah capacity, this will be your best option. It supports Active Balancing, 2 relay outputs, 2 opto outputs and up to 8 temp sensors. For Smart system integration it supports both Victron and WS500 communications on the CANBus network.
For systems up to 16 cells, the SI-Q Series Stand Alone BMS. This is the workhorse of the product line, includes an opto output for disabling remote charge devices, integrates with many inverters via CANBus and can be upgraded to work with a Master if you want to expand your system with additional banks in the future.
When you have a larger system with multiple packs of 4-16S cells that all need to brought together into one large system of up to 15 packs for monitoring, isolation, redundancy or integration the Parallel Master is the way to go. It works to supervise and aggregate all of the packs into a single integrated system. Along with all of the features of the SI-Q Series BMS it has 4 additional programmable relay outputs and voltage inputs that can be custom programmed for you.
For high voltage systems the Series Master will integrate up to 15 cell packs into one large series string of cells. Each pack of up to 16 cells is put in series to create you high voltage systemand will be custom configured based on your specific system requirements. We recommend submitting a requirements overview using the “System Config” form before or with your purchase of this system.
