Review: Easy to install, operate, and understand. - Update 2024-12-14: Actually looking like top balancing will recover 20% capacity. Heater puzzle solved. See below for info from JK BMS. The scene: After 6 years, converting two (24v) 8S 200Ah bottom balanced LFP cells to a single 16S 200Ah 52.1V battery. Installed BMS 6 days ago. The good: Super simple install. Connected to app immediately. Clear and easy to read manual (yes, really!) The great: Chugging away at top balancing the pack. At 2A, and as poorly balanced at the top these cells are, it’s made decent progress. Looking like I’ll be able to reclaim an easy 10% MORE capacity from these cells than I’ve ever had. The “Meh”: Can’t figure out WHEN the heater port will activate. CAN cable was missing. Only JK protocol supported CAN menu. Over All Grade: A+ Would I buy it again? Yep, as a matter I already have. If I figure out how to trigger the heater, I’ll update this. If I figure out how to get this to talk to my Victron gear, I’ll update this. I’ve played with pretty every setting. It works as documented. 2024-12-17 JK BMS sent info: Heating Function Activation Conditions: The heating function for charging will be activated when Condition 1 is met, along with Condition 2 or Condition 3. Condition 1: The battery temperature is below the charging low-temperature protection threshold. Condition 2: Heating is manually activated via the APP, without checking the charger status. Once the low-temperature condition is met, heating will begin, which will consume battery power. Condition 3: The charger is detected as being plugged in. This function is related to the hardware of the protection board and the charger, so please confirm the technical specifications before ordering. Heating Film Selection: Step 1: Determine the maximum battery pack voltage. For example, a 20-series LiFePO4 battery has a maximum voltage of 20 × 3.6V = 72V, while a 24-series LiFePO4 battery has a maximum voltage of 24 × 3.6V = 86.4V. Step 2: Calculate the resistance value of the heating film. The resistance value is calculated by dividing the maximum total voltage by the current: Resistance (Ω) = Maximum Total Voltage ÷ 3A. For example, 72V ÷ 3A = 24Ω. Based on this, select a heating film with a resistance close to this value. A suitable heating film specification would be 72V/24Ω/216W. Key Notes for Understanding: Condition 1 (Low-Temperature Protection): The heating function will only be triggered if the battery temperature drops below a certain threshold (often around 0°C to 5°C) to prevent damage to the battery and ensure it remains functional during cold weather conditions. Condition 2 (Manual Activation via APP): This condition allows the user to manually activate the heating function through an app, which will begin heating as soon as the low-temperature condition is met. However, this will drain battery power, which is important to consider in terms of overall efficiency. Condition 3 (Charger Detection): The heating function is also dependent on detecting whether the charger is plugged in. This ensures that the battery is being charged during the heating process, avoiding unnecessary power drain when not connected to a power source. Heating Film Specifications: The heating element (heating film) needs to be carefully selected based on the battery's total voltage and required current. The resistance of the heating film plays a key role in determining how efficiently the heat is generated without exceeding the system's power limits.
Review: Absolutely amazing! - Okay after testing this bms out for a couple months I can say it it absolutely amazing! My little homie recently bought a 72 V 21S6P battery and it wasn't working at all so we swapped the ANTBMS for this one and the battery performs amazingly now. It was able to fix a balancing issue that we were having before and it's so simple to set up this is my first time ever working on a battery pack like this super scary but super straightforward as well. Now we can fully charge the battery back to 84 V and it hasn't had a single issue since and we're pushing 75 A continuous with no problems so far.

### ⭐⭐⭐⭐⭐ Works well so far
*by J***M on May 12, 2026*

Works well so far. Not a ton of bluetooth range ~8ft inside the RV ~20ft outside. (I know the location is not helping but i had to mention it). And I wish the app had a nice SOC panel on the home page like Daly does. No issues with the app so far it feels simple and reliable nothing fancy. However after building this 12v 4s battery i think i would just go to a "dumb" drop in heated LFP battery with a nice warranty especially if space isn't a huge deal.
