## Description

Product description Protection Board Selection FAQ Q: What are "same port" and "different port"? A: For instance, with a 20S 60V 100A protection board, "same port" means your charging negative and discharging negative are connected at the same point (P-). They share a common interface, so both the charging current and discharging current are 100A. On the other hand, "different port" means the charging negative (C-) and discharging negative are separate (P-), connected at different points on the protection board. Thus, the charging and discharging currents can differ—discharging at 100A and charging at 100A. Q: Relationship Between Battery Capacity and Protection Board Current Q: What kind of charger should I choose? A: For lithium batteries, you must use a charger specifically designed for lithium batteries. Never use a lead-acid battery charger, as it could potentially exceed the protection board MOSFET's voltage tolerance, leading to overcharging without protection. For lithium iron phosphate batteries, charger voltage = number of series cells * 3.65V; for ternary lithium batteries, charger voltage = number of series cells * 4.25V.

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: Works great, no problems and smaller size. - This BMS has been preforming great for months now. Not one problem and it keeps the cells balanced. I like the small size and it still preforms as well as the larger BMS with the extra boards. Much easier to place in a battery build and has a screen to see what it’s doing, plus the app to view or change it all. I wondered about the smaller cables, and I wish they were a little longer. But it’s fine because I would always need to add more length anyway. And these never heat up. Great to also have 2 temp probes also. I liked this BMS so much I just bought another one for the next battery build. Great BMS!!

Fantastic product. Took me a while to build a battery and set up the BMS but worked like a charm and with the help of some great YouTube videos was able to complete the setting properly.
