BMS DALY Active Balance 4S 30A-TC LiFePO4 0.5A BAL,BT,WiFi<\/h2>\n
<\/div>\n
    \n
  • The BMS DALY Active Balance<\/b> series is the successor to the “blue” BMS 100Balance-Active series<\/g>. Compared to its predecessor, the socket design and temperature stability have been improved. DALY has also returned to the traditional red housing color. At the same time, all the features of the 100Balance-Active series have been retained. <\/li>\n
  • This BMS is the smallest and lightest Active BMS. This allows for the construction of small, compact packages, <\/li>\n
  • The BMS is equipped with an active high-current balancer. As the only model in the Active BMS series, it is designed for a specific number and type of cells: 4S LiFePO4. <\/li>\n
  • Wide communication capabilities of the BMS (BT mobile app, WiFi, RS485, CAN, screens, and indicators) allow for monitoring battery parameters and adjusting them to specialized needs.<\/li>\n
  • Common power port (P-) – it is not required to run a separate cable from the charger. Charging and discharging occur through the same wire. <\/li>\n
  • Before starting the BMS, it must be connected to the pack strictly according to the attached instructions.<\/li>\n
  • The BMS kit includes temperature probes, a switch, and a plug for the RS485\/CAN connector.<\/li>\n
  • NOTE: The BT module is built into the device. No additional module is required. <\/li>\n
  • Other accessories are not included in the set and can be purchased separately:<\/li>\n
  • Voltage indicator for Daly BMS H, K, M, S, and 100Balance<\/li>\n
  • Voltage indicator for BMS SMART Daly H,K,M,S.100Balance LCD 3″<\/li>\n
  • LCD touch screen for Daly BMS H, K, M, S, and 100Balance 4.3″<\/li>\n
  • WiFi module for BMS 100Balance Daly<\/li>\n
  • RS485 cable for programming Daly BMS H, K, M, S, and 100Balance<\/li>\n
  • NOTE: Despite the significant reduction in power consumption in the new BMS SMART series, there is a risk of battery discharge during prolonged storage. Such self-discharge is not monitored or controlled by the BMS. This can lead to cell damage, particularly in packs with lower capacity or those that were heavily discharged prior to storage. During long-term storage, periodic monitoring of the battery voltage and, if necessary, recharging is required. <\/li>\n
  • To program and monitor parameters, you need to download the application. It is available for both Android and iOS. <\/li>\n<\/ul>\n<\/section>\n<\/div>\n<\/section>\n
