Hi, I had a system installed last July with 2x HV2600 batteries. I’m looking at adding some more but I know there were issues with v1 v2 batteries/BMS.

Anyone know if this is still an issue? My batteries have ‘Ver D’ stickers on them and these at Tradesparky are ver D also?

Thanks in advance

Hi

All current version D batteries for sale are V1 batteries so no need to mess on with changing the BMS

If your current one are D then they will work but.

Also make sure once you’re installed them that your installer or fox update all the batteries to the same firmware version and update the firmware on the BMS or the system will not show the capacity of the new batteries. Then you need to do 7 full cycles to re calibrate the BMS

Some posts on here about balancing the batteries but that won’t work if the firmware is all different on the batteries

I’ve Just added some and had issue but found out this is the cure

Hope this helps

Thanks, that sounds great, owe you a beer
