![]() According to Chris Witzgall, the product manager for the SG200, it takes about three charge cycles for the SG200 to fully learn your battery bank’s characteristics and be able to accurately report on its status. A mix of what Balmar calls active impedance compensation and shunt-based monitoring is used to deliver this level of insight.īalmar says the SG200 can accurately measure State of Charge and State of Health for all major battery types including Lead Acid, AGM, Carbon Foam, TPPL and LiFePO4. The SG200 also reports on current consumption and total time remaining for the battery bank. With the SG200, Balmar has begun measuring your battery bank’s State of Health (SoH), which is delivered as a percentage representing the battery bank’s current capacity versus design capacity. Each SmartShunt can also monitor voltage for two auxiliary batteries, like engine start or similar non-deep-cycle applications. Since SmartLink allows the connection of 32 devices, you can monitor a large number of battery banks with displays located throughout the boat. It links to a sensor module named the SmartShunt via a 4-pin network connection called SmartLink. Balmar has streamlined the user interface to a 2-inch, sunlight-readable color display. Coupled with a very simple numeric-only display and the lack of support for lithium battery chemistries, there was definitely room for an update.Įnter the SG200. This lack of insight into consumption and charging was a significant limiting factor to many users. This meant that while the Smartgauge could tell you how charged your batteries were - somehow with more accuracy than more complex current counters according to power expert Rod Collins - it couldn’t tell you how much power was being used or replaced in real-time. The first generation Smartgauge differed from almost every other battery monitor on the market by measuring a battery bank’s State of Charge (SoC) using just two voltage wires. The SG200 combines the goodness of the highly regarded original Smartgauge with a shunt to deliver a more complete picture of what your batteries are doing. I recently judged the Innovation Awards at the International Boat Builders’ Exposition (IBEX) and we selected the new Balmar SG200 battery monitor as the winner of the Electrical Products category.
