## Features

- 【Improve performance】The smart active equalizer can intelligently control the power transfer between cells, better the battery consistency, prevent the premature deterioration of individual cells, and make the overall power of the battery pack stronger and more stable. Transfer power with 0-1 A current (tips: the balance current can be set by yourself), which is not resistance energy-consuming balance, reduces heat generation and can be connected to the battery pack for a long time.
- 【Intelligent Balance】Real-time intelligent balance. Not limited by battery charging, discharging, static and hibernation, once the cell voltage value reaches the set condition, it will intelligently turn on the power transmission until the voltage is balanced. (tips: The opening conditions can be set and modified, and the cell pressure difference needs to be more than or equal to 20mV)
- 【Strong adaptability】Daly smart active balancer can be applied to Li-ion, LifePO4 and LTO . DALY active balancer compatible with all other brands of bms . It is best to be used in parallel with the DALY BMS and the wire connection can be more easier.
- 【Quality Guarantee】 Daly smart active equalizer, dustproof, shockproof, antistatic, the shell can withstand 80 ℃ high temperature.Small size, easy to store. LED indicator, green light on - balanced; green light off - undervoltage/fault. It supports UART, RS485 and other functions, all Parameters can be checked and modified via Bluetooth App or UART USB Connection with PC Monitoring Program anytime.ISO/ FCC/ RoHS/ PSE/ CE APPROVED.
- 【Package】Smart Activer Balancer +Bluetooth Module +Matching Balance Wire+ Instruction Manual. (tips: the battery strings must be matched to the active balancer strings)
