Drone suggestion with flexible battery pack

[Chintanp]

Dear all,

Our group does battery research, specifically fast charging batteries and accurate state estimation, i.e, state of charge, time remaining etc. Drones are an interesting application, along with other EVs and consumer electronics like cell phones etc. We need suggestions for a drone that:

Allows a flexible sized battery pack - This is our most crucial requirement. Most drones have a small, fixed sized battery pack that it works with. We want to have a drone that allows custom, multiple sized, shaped packs. Ex: DJI Matrice 100 . As per my understanding, the battery pack is velcroed in place, allowing for flexibility in battery pack sizing and shape. However, this drone is super costly, huge and a sword when we need a needle. Another worthy alternative we considered is: the Intel Aero Ready to fly drone, however, the battery pack size is very small (50x36x150). Looks like Qualcomm drone developer kit has a similar problem and parts are out of stock for a long time. We might need something like 150x150bx400mm to house our packs.
Cheap (<= $2000)
Light (<= 10 pounds)
Easy to assemble/disassemble (so that we can showcase it in expos, conferences etc.)

Any suggestion or guidance would be appreciated.

Thanks

Have you considered building your own? Not very difficult, considering your background.

The drones youre talking about already have this info readily available. Building your own drone and creating something anyone could buy and add would be the better choice. HD Drones (Flying Cameras) are the only ones that this would apply to because Acro and race drones have an extremely sporadic power consumption and hardly fly longer than 4-5 minutes. It would be like trying to est MTE (miles till empty) on a drift car or motor cross bike.

Remember the bigger the battery, the heavier the battery. LiPo and LiON batteries are among the lightest, but are usually designed for the application, keeping in mind that weight must have more power to overcome it. Also the aerodynamics of the aircraft can and will be affected by increasing the weight factor versus the lift factor and general stability especially due to the kinetic energy imparted by the moving mass. Something about Newton's 3rd Law of Motion has effect.
