Description

New JK-BMS 16S 51.2v 200A V19 JK-PB2A16S20P V19

JK-PB2A16S20P V19

New BMS version with additional UART port for the new display which shows parallel batteries in all details. The port prepares the BMS for future upgrades and new accessories.

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

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 issues with firmware, and support being needed by most customers.

This JK BMS has recently been updated with new FIRMWARE, this has resolved all known issues. It is now the recommened BMS for all 48v, and some 24v packs.

Warranty is 3 Years in Australia.

Delivery Time is 2-3 Days by Express to most cities in Australia.
(rural and regional add 1-3 days) 

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 a future update

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.

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

Tim Stokes
Awesome service. Very knowledgeable. I have bought a number batteries from them and great experience each time.
Robert Robins
Purchased a Growatt Spf5000es inverter, pricing was very competitive and service was great. Highly recommend
Bruno Drinovac
Purchased a Deye inverter from LiFePo4 in June 2026. I am pleased to say that the inverter has been running perfectly with no issues for the last 1½ months. It has been installed into an off-grid system on a very recently built granny flat. This inverter was ideal for our situation and was easy to set up. The 2 trackers were very handy as we needed to deal with 2 different sets of strings operating at 2 different voltages. It certainly looks like a very well designed and robust inverter and will hopefully last us many, many years. If and when we need to replace the inverters on the main house, we will certainly be looking at using Deye.
LiFePo4 provided free delivery, which was very quick, arrived in only a couple of days. They sent me an email checking on how we were going with the installation and offered assistance if we needed it. Excellent Company to deal with and I would purchase from them again in future.

Been buying batteries from LIFEPO4 Australia for years, always A grade! Great to deal with. Great after sales support. Recommend highly.
Russell Vosseler
Mark and the team have done a great job finding the best solar and battery solution for my house, my parents house, and also friends' houses.
Their batteries are top quality, not like the cheap and nasty ones you find with "special low deals". Best to pay a little extra and get quality products.
Their aftersales service is exceptional with continual support after installation. Mark had provided guidance months after installation to maximise the production of my inverter, and continues to provide valued suggestions even now. 😀
Ken Baker
just received my 30 jinko panels this morning...from initial enquiry to delivery in metro adelaide was 4 days!...on top of that LifePo4 beat the other quotes on price so needless to say I am very happy with the purchase. highly recommend

I can’t speak highly enough of Mark at LiFePo4 Australia – they’ve now saved our motorhome adventure twice!
The latest drama hit when our battery failed mid-trip, leaving us in a power pickle. Even though it was outside business hours, Mark jumped on the phone and organised a replacement battery with lightning-fast turnaround.
This is the second time Mark has gone above and beyond for us – always friendly, knowledgeable and genuinely committed to getting you sorted. Couldn’t recommend them enough.
Response from LiFePo4 Australia

Thanks Steph. I'm glad we could assist. The cells you picked up before finding us at LIFEPO4 AUSTRALIA might have been B grade. We are glad we could help out with the 2 cells so far. If any of the others drop out, I'll send out replacements as quickly as we can. Enjoy your travels

Peter Demol
I had an excellent experience buying components to assemble 2 battery packs. Mark is extremely knowledgable about the products he sells. He answered all my questions, prices are excellent, and when there was a potential issue, he went over and above by supplying extra products at no extra cost. Shipping halfway across the country to a rural area took only 3 business days which is insanely fast. I am totally happy with my new batteries and with Mark's excellent customer service. After 10 years of FLA batteries, finally going to lithium technology is heaven. Thanks again Mark. Very happy customer.
Vicki Wattus
Awesome customer service, Mark went above and beyond in sorting my order when we ran into a few snags with it. I would recommend this company to anyone who values good price, service and a great customer experience.
Response from LiFePo4 Australia

It was my pleasure Vicki, we love helping out especially those who need a little bit of help. We hope your get years of service from the Victron MPPT and Jinko 510W solar panel, thanks for you patience over the weekend while we arranged the shipping for the panel to the depot nearest you. The $200 we saved on shipping, was well worth the delay over the weekend. Safe Travels Mark

Absolute legend of an owner great 10 star customer service and product and knowledge to match..!!!
Not just a salesman...anything but absolute legendary service and knowledge to suit..

Cells arrived, a bit of a delay. But overall we'll priced and packaged.
garry miille
Mark knows what he is talking about when it comes to batteries. Great pricing and very helpful too. Just a great experience all round.
Dapper Rausimen
I totally agree with the other 5 star reviews and can highly recommend buying lithium cells from this business. I received my order of 72 automotive MB31 batteries quickly and I am very impressed. All the cells were within 0.01 of a volt so didn’t require balancing or top charging before installing. They are the real deal A+ automotive grade EVE cells as advertised and not B grade rubbish some online sellers are supplying. Mark actually answers the phone if you need to discuss anything before purchasing and is one of the few people I have found selling lithium batteries that actually now’s about how to install and set voltage settings in the BMS’s he sells.
Elliot C
Super helpful gentleman. I barely prompted him and he gave me plenty of important and useful information. Best customer service I have had in as long as I can remember.
