Hello as a lover of profoto, I am not sure why you would design the battery power worse than those from other brands such as Godox and so on.
Please have more power and I will be more willing to buy your new modules in the future!! Please do😆
For the B1 and B1x series, a battery cover is available (see attached image). This is handy to avoid damages when having >1 battery. Also handy for travelling in a aircraft. Is somethign likewise also possible for the B10 series and A-series?
