2023: BMS Systems Changing & Improving

[SilverFox33]

When you listed JK BMS's:

"currently there are 3 versions around, 2 of which are older, one is current.
10c - canbus inverter comms only - older
10d - rs485 inverter comms only - older

10e - newest and current both rs485 and canbus.
can communicate directly with both 10c and 10d, however, not both at the same time.

10c also has a bluetooth option and app

the difference in hardware is also the reason 2 older versions cant communicate to each other"

I think you were talking about firmware only?

I have (3) JK-B2A24S15P units which I got on 'special' when I ordered my batteries. They work pretty well, though oddly they sometimes say Discharge is 0.0 while I know the batteries are discharging (reading 'em with a DC current meter at 35A).

I am successfully communicating with my (3) JK BMS's with Bluetooth. I'd like to set up longer range communications with them.

My question is: do my JK BMS's support CAN? rs485?

Stewart pittaway's diybms is starting to become extraordinary interesting..

Communications
Shunt
Passive balancer, with heltec 10a balancer steering support

Just about all features you would want as opensource code and hardware design.
Only downside: soldering...

Shame

And finally a new version of the JKBMS with features of the "industrial" grade BMSs - includes active balancing and firmware upgradeable and inverter comms. Be interesting to see if any bugs in the first release version. https://www.aliexpress.com/item/1005006014535487.htm (pre-order)

That link has disappeared. Maybe JK pulled it? Was there a model number, so I can search for it in the future?

Hankzor have it listed for pre order here:

Very impressive unit. Big like Pace, Seplos, TDT, etc. Since it has upgradable firmware, it is very tempting to pre-order. If the firmware upgrading process actually works. Likely that there will be some bugs in the first versions, but then with firmware upgrades these can be fixed.

watching this. with built in active balancing and UPGRADE YES presumably meaning "firmware update process is supported" it is quite interesting as an alternative to my current BMS which only has passive balancing.
