Mount and Blade 2 Bannerlord will allow you to store more items by increasing the lifting capacity. This is especially important during war, when you don't have time to go back to the city to sell the loot. The increased capacity of the equipment is also useful at the beginning of the game - hunting bandits is a good way to make money, and the increased capacity will allow you to take all items from the defeated enemies. This section of the guide explains how to increase the lifting capacity in Bannerlord.
How to increase capacity?
Maximum capacity in Mount and Blade 2 Bannerlord can be increased in two ways. The first is recruiting new units - each soldier increases the maximum capacity. Here, you're only limited by the size of your army. The easier way is to buy a few horses and keep them around. Any horse, mule or camel affects the carrying capacity of your character. Mules can carry the most items, but are slowest. The universal solution is to have only horses. You can either buy the horses, or get them from defeated enemies.
