Smart BMS JK PB-2A16S20P with 2 Amp Active Balancer

Warranty is 3 Years in Australia

This JK-PB2A16S-20P 200A 51.2v BMS comes with all wiring, bolts and cables. We needed to adjust the pricing on these due to many issues with firmware, faulty units and support being needed by most customers. After selling quite a few of these, we must state, that we now test these all here in Australia, so any faulty DOD (Dead on arrival warranty claims will be denied) because we now test them before they are sent to you.  This BMS has quirks, and is not like other BMS, for example on the third wiring harness for the cells 9-12 the first red wire, should not be connected to anything. This will burn out the BMS if connected.

This BMS is still the best on paper hardware specs and makes building a pack ridiculously easy, with no top balance being needed because of the high balance current.  The integrations with Victron, Growatt and DEYE are all good. Although still quite fidily. The app is pretty good, but not quite perfect, and still no way to backup and save your own pack settings, Fingers crossed this will come in 2024. Sooner than later.

If you are looking for a reliable and efficient battery management system (BMS) for your lithium-ion battery pack, you might want to consider the JK-PB2A16S-20P model made by JK BMS. This product is designed to monitor and protect your battery cells from overcharging, over discharging, overcurrent, short circuit, and temperature anomalies. It also balances the voltage and current of each cell to optimize the performance and lifespan of your battery pack.

It is suitable for 16S (48V) lithium-ion and Lithium Iron Phospahte battery packs. It supports various communication protocols such as UART, CAN, and Bluetooth, and can be configured via a PC software or a mobile app. It also has a LED display that shows the status of the battery pack and an alarm buzzer that warns you of any faults. The JK-PB2A16S-20P model is a high-quality product that has passed various certifications such as CE, RoHS, FCC, and UL. It has a warranty period of one year from the factory, however we are so sure it will perform we will provide our Australian customers with a 3 YEAR warranty, just provide us with photos of the installation, and we will happily co-operate if you follow our warranty process.

As well as the standard features you’d come to expect from your BMS, the JK-PB2A16S-20P 200A Smart BMS also contains a whole host of additional features. Such as the Parallel charging current limiting to 10A to protect the battery from inrush currents.

This intelligent lithium battery protection board also features advanced active voltage balancing, allowing for real-time monitoring and active balancing management of each battery cell. This means improved battery life and performance.

Additionally, the JK BMS allows you to control and adapt cell operating functions, perform diagnostics and record data, determine critical levels such as pack State of Health (SOH) and State of Charge (SOC). You can access this data through the dedicated JK app, available on Android and iOS.

Note: JK provide no instructions with their BMS apart from those included in the downloadable PDF. We strongly recommend that you have a good working knowledge of LiFePO4 systems and BMS electrical equipment before purchasing this product.

We do not mind if you choose to buy this BMS from the official store here or here

Here is a pretty high quality review of the BMS from a South African Youtube Channel
