I'm sure the battery brand is fine. But i'm curious what other brands would actually fit fine in the hadron frame. This is direct from the manual, 1600mah 30c 4s(23.68wh) 88.5mmX 36mmX 28.5mm. Unfortunately I do not own a digital caliper to get a much more precise measurement of the internal mod enclosure dimensions. What I do know is the height of this lipo is probably the absolute max height a lipo can be to fit. Any higher & the lids wouldn't fully seat. Wish it was a slightly wider mod. Every 4s I keep seeing is more height than this fullymax lipo. I been using this mod moderately every single day for about a year now, having to recharge about everyday for the year. I think the time is nearing for a new battery. Would like to get 1-2 extras.
