I personally do advise going with the High Capacity Batteries. Worth the extra flight time and more importantly we've been seeing far less DOA units with the High Capacity Batteries so I'd like to say they are more reliable as I would assume the intelligent board on the High Cap Batteries most likely got some updating as the regular P4 Batteries were very prone to arriving DOA.
If you're looking for another battery we're got plenty of the new High Capacity Phantom 4 Batteries in stock. Link below, as always, free shipping on orders over $150 and in stock orders placed before 4pm PST are guaranteed for same day shipping.
