"@Francis, we haven't tested with solo, but since it's using pixhawk, it should be."

"Great development! Will it be possible to use with "normal" batteries on the 3DR Solo?"

"We didn't have enquiry for lower than 6s batteries. But can make 4s versions if there is enough interest."

Aero Hawk commented on Echo G's blog post Batmon: Pixhawk compatible, in-flight battery monitors with LED display
"I noticed that it says that you can only use it for 6-10s batteries. Will there be a chance that it could also monitor lower battery voltages like 4s?"

"@Evan, there is hardware and module support for reading cell voltages. There is just some minor aspects that have to be changed, which can be shared if you are interested."

"@Andreas, the screen adds 4gm to board. But yes, there is a version without the screen. Please PM me your requirement."

"Regarding Point #5:This is using SMBus to communicate with the flight controller, if I am not mistaken. ArduPilot does support cell voltage readings over SMBus (originally intended for SBS 1.1 batteries). Is there information available as to what…"

"Thank you, I can't believe that this obvious piece of tech has taken so long to be developed. Can you drop the weight / size / price further by making a version without a screen? What's the rough price?"

Batmon: Pixhawk compatible, in-flight battery monitors with LED display

Happy new year to all flyers. We want to update the progress made on an in-flight battery monitor. Initial revisions of the board were meant to capture accurate cell voltages for the flight batteries. However, lot of feedback was received to push the board towards a minimal Battery Monitoring System. Currently, most diy'ers and professional flyers use large battery packs…See More

"Hi, I'm extremely interested. Are they any still available or when will you be doing another manufacturing run. Also, any news on the CAN integration?? "

"@Edward, Sure, will update when there is CAN version."

Edward Sellars commented on Echo G's blog post Low current drain battery monitor with pixhawk interface (10 cell)
"Im in for sure when there is a can version. Anything but i2c. Start plotting large amounts of data and see what type of noise creeps in through i2c. Just a bad interface. Uart is much better if those are the only options but with something having…"

Echo G commented on Echo G's blog post Low current drain battery monitor with pixhawk interface (10 cell)
"@Edward, We have tested the board for several hours in flight on multirotors without any issue from i2c. But you are right that i2c isn't the ideal protocol for this. We have also not tested it with data lines longer than a 1 ft. The CAN…"

Edward Sellars commented on Echo G's blog post Low current drain battery monitor with pixhawk interface (10 cell)
"Totally interested except a few unanswered things. What type of testing and support have you done in the firmware side, i2c really is not the way to go on this. Too many problems and with current and magnetic interference going around so…"

Echo G commented on Echo G's blog post Low current drain battery monitor with pixhawk interface (10 cell)
"@Guy: not yet . But we will be working on stackable modules if there is interest @Hugues: it will communicate over i2c or uart . There will be a firmware update to read the cell's voltage"

Low current drain battery monitor with pixhawk interface (10 cell)

In-flight monitoring of total battery voltage and individual cell voltage is important for accurately estimating flight time. Monitoring the cell voltages during flight and operating load conditions help to predict battery health and cell degradation. 
We designed a battery monitor board to interface with pixhawk to read the cell voltages of flight…
