It delivers up to 150A continuous current with 2A active balancing to optimize cell health and pack longevity. Featuring Bluetooth app integration, it offers real-time monitoring and configurable protections, making it perfect for advanced solar, EV, and off-grid power applications. ## Description Protection Board Selection FAQ 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. A: The size of the battery capacity does not directly correlate with the current of the board. Capacity is not about the physical size of the battery but rather the continuous current. It depends on your controller's current limiting—the higher the limit, the larger the continuous current rating needed for the protection board. It's not directly related to battery capacity. 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. A: The current rating of the protection board depends on the current limit set by the controller, which in turn depends on the power of the motor. For example, if the motor is 64V, 1000W, then the current is 1000/64 = 15.6A. Therefore, the controller's current limit must be greater than 15.6A, and the protection board's current limit must be greater than the controller's limit. Always leave a margin during the selection process. ## Features - 150A SMART BMS WITH 2A ACTIVE BALANCING: JK-B2A24S15P supports up to 150A continuous charge and discharge current, while 2A active balancing helps reduce cell-voltage differences and maintain pack consistency - PRECISE CHEMISTRY & SERIES MATCHING: Configure the BMS for 7S-24S Li-ion/NMC, 8S-24S LiFePO4 or 14S-24S LTO systems; choose the correct chemistry and series count before installation - BLUETOOTH APP CONTROL: Built-in Bluetooth connects the BMS to the JK BMS app to view cell voltage, pack voltage, current, SOC, temperature and alarms and adjust supported protection and balancing settings - CONFIGURABLE BMS PROTECTION: Supports charge overvoltage and overcurrent, discharge undervoltage and overcurrent, short-circuit and temperature protection with high-precision cell-voltage acquisition - FLEXIBLE BMS APPLICATIONS: Use this BMS across supported series configurations for solar storage, RV, marine, golf cart, electric vehicle, forklift and backup power; select by chemistry, series count and current rating rather than nominal voltage alone ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0D17J36JC | | Best Sellers Rank | #85,905 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #69 in Lab Power Supplies #119 in Life Science Supplies | | Brand | JKBMS | | Color | JK BMS | | Customer Reviews | 4.5 4.5 out of 5 stars (30) 4.5 out of 5 stars | | Input Voltage | 72 volts | | Item Dimensions | 6.38 x 4.02 x 0.8 inches | | Item Highlight | LiFePO4/Li-ion/LTO, 2A Active Balancing, Cell Monitoring, 48V-72V Solar, EV, Off-Grid and DIY Battery Packs | | Item Weight | 15.2 ounces | | Manufacturer | JKBMS | | Mfr Part Number | JK-B2A24S15P | | Model Number | JK-B2A24S15P | | Number Of Items | 1 | | Output Voltage | 72 volts | | Plug Type | JST Connector | | Power Source | Battery-Powered | | Warranty Description | 1 year manufacturer | ## Product Details - **Brand:** JKBMS - **Color:** JK BMS - **Input Voltage:** 72 volts - **Item Weight:** 15.2 ounces - **Item dimensions L x W x H:** 6.38 x 4.02 x 0.8 inches ## Images ![JKBMS JK-B2A24S15P Smart BMS 8S-24S 150A 2A Active Balance Bluetooth - Image 1](https://m.media-amazon.com/images/I/61fBxtTPI0L.jpg) ![JKBMS JK-B2A24S15P Smart BMS 8S-24S 150A 2A Active Balance Bluetooth - Image 2](https://m.media-amazon.com/images/I/71ogWycSCbL.jpg) ![JKBMS JK-B2A24S15P Smart BMS 8S-24S 150A 2A Active Balance Bluetooth - Image 3](https://m.media-amazon.com/images/I/711kYv7s2ZL.jpg) ![JKBMS JK-B2A24S15P Smart BMS 8S-24S 150A 2A Active Balance Bluetooth - Image 4](https://m.media-amazon.com/images/I/817orlbmFzL.jpg) ![JKBMS JK-B2A24S15P Smart BMS 8S-24S 150A 2A Active Balance Bluetooth - Image 5](https://m.media-amazon.com/images/I/71RUeVfyGrL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - JKBMS Smart BMS 8S-24S 24V-72V 150A 2A Active Balance BMS Built-in Bluetooth with RS485 PCB Battery Protection Board for LiFePO4 Li-ion LTO Battery Pack (JK-B2A24S15P) - JKBMS Accessory 4.3 Inch LCD Touch Screen Monitor with Switch for JK BMS LiFePO4 Li-ion Battery Protection Board --- ## 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.pt/products/631392471-jkbms-jk-b2a24s15p-smart-bms-8s-24s-150a-2a-active](https://www.desertcart.pt/products/631392471-jkbms-jk-b2a24s15p-smart-bms-8s-24s-150a-2a-active) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-21*
