Multiple and comprehensive protections Supports parallel connection of various battery pack and safe expansion Integrated parallel module to avoid large current impacts when battery packs are connected in parallel. Making load easy yo start High-power pre-charging can effectively avoid false triggering of protection caused by high current at startup moment and unsuccessful power-ups. 100mA passive balancing helps extend lithium battery life Compared with conventional BMS(with 30mA passive balancing),the balancing efficiency is increased by more than 3 times. Battey pack temperature protection,prevent safety hazards Advance temperature warning and timely power cut-off can effectively prevent battery fires and other hidden dangers.

Large storage space+High precision Large storage space It can massively store 400pcs of historical information (512Kb), including protection times, current total voltage, current,temperature, SOC, etc., and another 4Gb large memory can be customized. High precision High-end MCU chip, voltage detection accuracy +10-15mV,short circuit protection reaction 10~500uS, SOC deviation <5%(*above data are test results at room temperature) Snap-on plug Sampling cables and communication wires use snap-on plugs, which can be tightly connected to BMS and not easy to fall off,also make communication stable. Small size,easyto install Small size saves space and with screw holesfor easy installation. Note: The above picture shows 8S 60A BMS (K-series) as an example.Please refer to the specifications for the specific BMS size. Review: Easy to install, works right away, nice interface - Got this on 2 of my lithium battery banks. Works really well, easy to access over WiFi and/or Bluetooth. The version I got came with the WiFi and I added the Bluetooth adapter that came with the separate balancer. Together they work seemlessly and are doing exactly as they should be doing. Review: Works good - Out of 5 only ine had a problem and it was quickly replaced.. ## Features - Enhanced Battery Safety: Daly 12V BMS 4S offers protection against overcharging, overdischarging, overcurrent, short circuits and extreme temperature, ensuring the safety and longevity of your battery pack. - 2-in-1 Bluetooth/Wi-Fi Dongle: Easily connect with the app via Bluetooth, or switch to Wi-Fi for long-distance control when Bluetooth is out of range (requires connection to a Wi-Fi router).

Works really well, easy to access over WiFi and/or Bluetooth. The version I got came with the WiFi and I added the Bluetooth adapter that came with the separate balancer. Together they work seemlessly and are doing exactly as they should be doing. ### ⭐⭐⭐⭐⭐ Works good *by C***K on March 25, 2026* Out of 5 only ine had a problem and it was quickly replaced.. ### ⭐⭐⭐⭐ not bad, not bad at all *by K***K on August 26, 2024* i got 4 of these to maintain 4 banks of 320ah lifepo cells, 16 total, 4 per pack. it was very aggrivating trying to install these with little to no documentation, yea, there's videos but they dont really go into much detail. to all buyers, know this, "THEY WILL NOT ACTIVATE UNTIL YOU PUT A CHARGE TO THEM. this does not matter if your cells are pre-charged for storage or not. once there is a push to them through the bms, they will come alive. however, without putting a charge to the bms/battery bank, they will NEVER come online, and they will NEVER be seen by the APP. it was very aggrivating that i couldnt check the bank before connecting it to my system. i had to build the bank, and hope for the best then connect it up and attempt a charge.. before i could even see the bms.. which sucks from an engineering standpoint. also keep in mind, these bms do get hot, they do not have a built in cooling fan..something to consider.. they maybe only 100 amp, but they do get hot when they are pushed to 80-90 amps.. otherwise, once they are up and running, they do pretty good. i've had them on a 43 foot sailboat behind a victron 3k-watt inverter, and they doing great.. just wish they would make it do MPPT modbus over tcp.. its a basic protocol, so i dont know why they dont do it. it would also help if the wireless module wasn't just bluetooth. so i'm building a esp32 gateway to convert ra485 to mppt modbus so that i can read them with my victron cerebro gx. will buy them again if i ever build another cell bank.. ## Frequently Bought Together - DALY Smart BMS 4S 12V 100A with WiFi Module and CAN 485 Communication Protection Board for Remote Monitoring of LifePO4 Lithium Battery Pack - Daly 5A Active Equalizer 16S Active Balancer for Lifepo4 Li-ion LTO Battery Groups Capacitor Balancer - 100Balance 4S 5A Battery Active Equalizer Balancer for Lifepo4 or NCM Li-ion Lithium Battery Group BMS Energy Transfer Board with Blue ABS Case --- ## 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/623729122-daly-smart-bms-4s-12v-100a-with-wifi-module-can](https://www.desertcart.in/products/623729122-daly-smart-bms-4s-12v-100a-with-wifi-module-can) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-30*
