It's more a problem of system knowledge. A lot of people do not understand what they have and use descriptions that are inaccurate. The Typhoon H and Typhoon H Pro are for general purposes the same H-480 aircraft. Both the Typhoon H and Typhoon H Pro use the same 14.8V 4S LiPo battery and can carry either the CGO3+ or CGO-ET cameras. Some get further confused when they describe their controller for those aircraft, calling one an ST-16 and the other an ST-16+. Again, their controllers are essentially the same unit. With both the aircraft and controllers the difference is simply 1 external item added to the aircraft or controller. The H Pro is different from the standard H because of the addition of a Real Sense module at the bottom rear of the aircraft. The ST-16 controller for the Pro had a third external antenna added to the top of the controller, which for some reason caused people to believe made it more superior and so started calling it a "+". As far as funtionality is concerned both the ST-16 and ST-16+ are identical as the original two external antenna version of the ST-16 has the third antenna inside the transmitter case. Neither the ST-16 or ST-16+ can be used to control an H Plus. To re-cap, both the H and H Pro, ST-16 and ST-16+ are the same aircraft and controller, having only externally mounted equipment differences. They all employ the same basic hardware and use exactly the same cameras, batteries, and firmware.
The H Plus is a completely different system, larger in size (520mm) using a different camera (C-23), different flight control system, along with the ST-16S flight controller that employs many internal changes. The ST-16S cannot be used to control an H or H Pro. The Typhoon H Plus uses a 15.2V 4S LiHV battery but can make use of the original H and H Pro 14.8V batteries but experiences a shorter flight time when doing so. Extra vigilance needs to be employed when using an H battery with an H Plus as voltage will drop faster and alarm/voltage indicator settings can present differently.
As the LiHV battery is relatively new to the market, those using one need to look for chargers of more recent design. Older chargers will often not have a selection for LiHV as the charger was designed and produced before the advent of higher voltage lithium batteries. When researching products for possible purchase a little extra effort has to be expended to assure the desired selection possesses settings for LiHV in order to fully charge that type of battery. As we often visit sites like Amazon or eBay to review an item for purchase an issue arises where sites like Amazon and eBay frequently do not provide a full product description. We should visit manufacturer websites and conduct a full review of a manufacturer's specification sheets to make accurate decisions, and then visit the sites we make purchases from.
