Projecta BM500 vs DCS Lithium

TBB'battery monitor kit is composed by a battery shunt and a monitor which allow the user to fully understand his/her battery. Here is some quick facts of this kit: 1) Measurement current is up to 500A 2) Is able to work with battery (or battery bank) 12Vdc, 24Vdc or 48Vdc 3) Compatible with AGM, GEL or LFP battery 4) An elegant design monitor to display battery information such as current, voltage, SOC, time remaining etc. 5) The monitor could be installed at any location where with easy access to users 6) Measurement accuracy: Current: +/- 0.4% Voltage: +/- 0.3%

DCS Lithium battery monitoring system. Time Remaining; Time remaining or time-to-go averaging period controls how smooth or stable the "Time remaining" estimate is. It does this by averaging load data over a set period of time (in minutes). The default value is 3 minutes. If you set it to 0 minutes, the system will show real-time duration without any averaging. However, this can make the "Time remaining" estimate jump around a lot. If you set it to 3 minutes, the system will smooth out short-term changes and only consider long-term trends, making the "Time remaining" estimate more stable. Cycle Count; The cycle count shows how much the battery has been used over its lifetime. For example, a 48V battery that powers a family home all day, every day, might rack up 200 cycles per year. On the other hand, a 12V battery in a caravan or fishing boat that’s only used occasionally might only reach 10 cycles per year. All DCS batteries come with an unlimited cycle warranty, meaning it doesn’t matter how often or how hard you use them - they’re built to last longer than any other batteries on the market. The "Current threshold" is fixed at 0.2A which helps ignore tiny electrical currents that could cause inaccurate battery readings. If the actual current is 0.0A but small electrical noise makes the battery monitor detect -0.05A, over time, this could incorrectly show that the battery is empty or needs recharging. With the Current Threshold fixed to 0.2A, the monitoring system treats anything smaller as zero, preventing these small errors and keeping the battery readings accurate. For a 12V battery to be considered fully charged, its voltage must be at least 14.0V. Once the battery monitor detects that the voltage has exceeded this level and the charging current has dropped below a set limit for a certain period, it will update the battery’s state of charge to 100%. Battery Status; A battery pack can be in one of three main states: Charging – The battery is gaining power Discharging – The battery is being used to power something Standby – The battery is in low-power mode, not charging or discharging While charging, the Battery Management System (BMS) checks the battery’s temperature and capacity to indicate whether it's being charged at a normal, fast, or super-fast rate. If something unusual happens - like the battery being completely drained, overcharged, charged too quickly, or getting too hot or too cold - the system will detect and display this information.
