This battery is AMAZING!
I went through SOO many hi-caps and 6 times as many mid-caps in my KWA firing at 1200 rpm, and lasted me 2 days.
it may be a tincy bit over-exagerated, but seriously, not much.
I almsot forgot, i didnt even finish charging on my smart charger, and it lasted this long.
-Life not even fully charged is amazing. About 4000 shots fully charged, seeing as bb fired = 2x mAh, but it seems I've reached that on partial charge. (1 1/2 hrs)
-It fits any where, full stocks, crane stocks, M4 handguards... idk what else is left. it looked so much bigger on the picture, but is actually really small.
-Durable, most cheap battery connections break, but this is been used alot and still holding together, but then again its Intellect.
