Can you employ different Holy Stone batteries?

Often, drone batteries are manufactured to be supported by one and just one particular drone due to the load, design, energy necessities, and lots of different elements.

However on this case, the 2S battery we’re speaking about is cross-compatible with the Holy Stone HS720 and HS720E, that are two barely completely different drones.

However because the documentation behind this battery is poor, we can not affirm 100% these perks. And consider me, deliberately short-circuiting the battery simply to examine if it has this safety is a nasty concept.

Nonetheless, realizing the battery’s conduct when charging or discharging it in flight, we do anticipate to have at the least these perks.
