You are welcome to buy daly products in the only DALY OFFICIAL desertcart STORE. Any questions pls contact our online service directly ~ Review: Avoid seller - Defective half of the inputs not working. ## 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) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B5MPD6VR | | Amperage | 1 Amps | | Antenna Location | PC | | Battery Capacity | 3.7 Volts | | Battery Cell Type | Lithium Ion | | Battery capacity | 3.7 Volts | | Battery cell composition | Lithium Ion | | Best Sellers Rank | 430,400 in Automotive ( See Top 100 in Automotive ) 763 in Motorbike Batteries | | Box Contents | Smart Activer Balancer | | Brand | DALY | | Brand Name | DALY | | Customer Reviews | 4.1 out of 5 stars 123 Reviews | | Item Dimensions | 11.5 x 6.5 x 1.9 centimetres | | Item height | 19 millimetres | | Manufacturer | Dongguan Daly Electronics Co., Ltd | | Model Name | AM3D13 | | Model Number | 4S Smart Active Balancer 1A | | Number of Batteries | 1 A batteries required. | | Number of batteries | 1 A batteries required. | | Recommended uses for product | PC | | Reusability | Rechargeable | | UPC | 768655914072 | | Unit Count | 1.0 count | | Unit count | 1.0 count | | Voltage | 3.7 Volts | ## Product Details - **Number of batteries:** 1 A batteries required. - **Brand:** DALY - **Battery cell composition:** Lithium Ion - **Battery capacity:** 3.7 Volts - **Recommended uses for product:** PC ## Images ![Daly Battery Equalizer 4S 1A with Bluetooth App and Wire Leads And Compatible Active Balancer For Lithium Battery Rated 3.7V 3.2V 2.2V - Image 1](https://m.media-amazon.com/images/I/61ACrfMO8WL.jpg) ## Customer Reviews ### ⭐ Avoid seller *by P***N on 29 September 2025* Defective half of the inputs not working. ## Frequently Bought Together - Daly Battery Equalizer 4S 1A with Bluetooth App and Wire Leads And Compatible Active Balancer For Lithium Battery Rated 3.7V 3.2V 2.2V - Bolatus Battery Isolator Switch 12V 24V 48V Battery Switch 275A Battery Kill Switch 1-2-Both-OFF Battery Cut Off Switch for Car Truck Boat Yacht Caravan Motorcycle - XBERSTAR 10pcs 3240 Epoxy Board FR-4 for DIY Battery Pack 20.3cm*17.2cm*0.05cm 3240 Epoxy Plate FR4 Epoxy Sheet Resin Fiberglass Plate Insulating Plate Heat --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/567744658-daly-battery-equalizer-4s-1a-with-bluetooth-app-and-wire](https://www.desertcart.in/products/567744658-daly-battery-equalizer-4s-1a-with-bluetooth-app-and-wire) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-03*
