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 - 200A HIGH-CURRENT BMS WITH ACTIVE BALANCING TECHNOLOGY: Designed for high-capacity lithium battery packs, JK-B2A24S20P helps maintain cell consistency through active energy transfer balancing technology - 24S LIFEPO4 BMS FOR HIGH-VOLTAGE BATTERY PACKS: Supports 8S-24S lithium battery systems with 200A current capability, suitable for large-capacity LiFePO4 battery applications - BLUETOOTH SMART MONITORING THROUGH JK BMS APP: Monitor cell voltage, pack voltage, current, capacity, temperature and SOC through Bluetooth connection for convenient battery management - ADVANCED BATTERY MANAGEMENT FOR LARGE SYSTEMS: Provides battery capacity calculation, voltage monitoring and current measurement to help users track battery performance - COMPLETE LITHIUM BATTERY PROTECTION: Includes overcharge, overdischarge, overcurrent, temperature and short-circuit protection designed for lithium battery systems ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0D5M3RCK6 | | Best Sellers Rank | #49,994 in Tools & Home Improvement (See Top 100 in Tools & Home Improvement) #218 in Power Converters | | Brand | JKBMS | | Color | JK BMS | | Customer Reviews | 3.7 3.7 out of 5 stars (5) 3.7 out of 5 stars | | Input Voltage | 72 volts | | Item Dimensions | 6.38 x 4.02 x 0.8 inches | | Item Weight | 15.2 ounces | | Manufacturer | JKBMS | | Mfr Part Number | JK-B2A24S20P | | Model Number | JK-B2A24S20P | | Number Of Items | 1 | | Output Voltage | 72 volts | | Plug Type | JST Connector | | Power Source | Battery-Powered | | Unit Count | 1 Count | | 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-B2A24S20P 8S-24S 200A LiFePO4 BMS, 2A Active Balance - Image 1](https://m.media-amazon.com/images/I/61fBxtTPI0L.jpg) ![JKBMS JK-B2A24S20P 8S-24S 200A LiFePO4 BMS, 2A Active Balance - Image 2](https://m.media-amazon.com/images/I/71a1Uy934BL.jpg) ![JKBMS JK-B2A24S20P 8S-24S 200A LiFePO4 BMS, 2A Active Balance - Image 3](https://m.media-amazon.com/images/I/711kYv7s2ZL.jpg) ![JKBMS JK-B2A24S20P 8S-24S 200A LiFePO4 BMS, 2A Active Balance - Image 4](https://m.media-amazon.com/images/I/817orlbmFzL.jpg) ![JKBMS JK-B2A24S20P 8S-24S 200A LiFePO4 BMS, 2A Active Balance - Image 5](https://m.media-amazon.com/images/I/71RUeVfyGrL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐ Great BMS. Bad App *by on Reviewed in the United States October 30, 2024* Love the BMS, very flexible. Wish it would be constant on if the start button were removed. App is barely functional and bluetooth is weak. These are not reasons to not buy it. You only have to manage it once. They work well enough ### ⭐⭐⭐⭐⭐ Finally…A real BMS *by on Reviewed in the United States September 23, 2024* If you’re looking to build your own battery pack a BMS is essential. I bought other ones from Daly (red and black) as well as Daly’s better line called 100 Balance which are blue. This BMS is WAY better and so is the APP.My biggest complaint about the Daly is that even the “active balance” is only active while charging. This one will balance the pack charging or not and it can do it at 2 amps which is much faster. The app instantly connects. The app is much more responsive to changes where the Daly had seconds of delay in showing how much current was being drawn by the motor. This one has any setting you could ever want where the Daly is much more basic. I am super happy. ### ⭐ Won't charge. *by on Reviewed in the United States January 27, 2025* I cannot connect to the bms. It will not charge. Email the company and no response. Past return window. ## Frequently Bought Together - JKBMS Smart BMS 8S-24S 200A 2A Active Balance Built-in Bluetooth with RS485 PCB Battery Protection Board for Li-ion LiFePO4 LTO Battery Pack (JK-B2A24S20P) - Flush Mount LED Pods, Niwaker 2Pcs 5'' 100W CREE LED Work Light Off Road Driving Lights Waterproof Fog Lamps Spot Backup Lighting Flush Mount Reverse Lights for Truck ATV UTV Tractor RV Boat --- ## 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.be/products/655834083-jkbms-jk-b2a24s20p-8s-24s-200a-lifepo4-bms-2a-active](https://www.desertcart.be/products/655834083-jkbms-jk-b2a24s20p-8s-24s-200a-lifepo4-bms-2a-active) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-14*
