includes: a "BMS08C3_V4.00_APP.hex" file , usb driver for windows, and an update program I hope is all compatible for my situation.
I just discovered the Chargery BMS8T w 300 amp shunt I purchased awhile back from ICGOGOGO store is version BMS08C3 V1.22. (although that info. might refer to LCD version only?) I thought I purchased BMS8T v 3.01 or 3.03. Wish I knew I could have ordered through Craig or Jason when I ordered it.
Running through the menu after wiring up to my 8 LiFePO4 battery cells revealed what seemed to me: lame or handicapped adjustment options/ on my 1st take of exploring the menu today. I was not able to adjust anything to LifePO4. Unit started up w LIPO on interface before I got into menus.
I am getting close to testing my 24v 280 Ah LiFePO4 set for capacity via turning on my LV2424s for a battery draw down. on way, ... I am going to attempt to update my Chargery BMS8T main unit plus the LCD to V.4.0 using the update instructions from link above, that came from the latest V4.00 manual.
Anyone done this already? If anyone has insights to offer, I am all eyes if someone posts anything. I will let you know what happen with my efforts later.
One insight from studying further is there are two separate update files:
BMS8T main unit update to V1.22
BMS8T LCD module update to V3.03
Maybe my main unit is V 3.03, but I could not tell via LCD interface. Hope my update effort renders what I obtained more usable for my needs.
