After my last article on parallel charging someone on facebook mentioned that they prefer serial charging.
Serial charging? Never heard of that.
Turns out this method is mainly used for 1S batteries, you basically build a 6S battery from six single 1S batteries and charge this constellation like you would charge a normal 6S battery. This is all done via a simple harness to which you plug in your 1S batteries in series.

When it comes to parallel charging there are a couple of ways that you can interpret it:
-
You have multiple chargers and thus can charge multiple batteries at one time. This is the most obvious version, but comes with the big draw back that you need multiples of everything, multiple power supplies and multiple chargers.
-
Multi channel chargers: Those are chargers that have multiple dedicated charging circuits, so you can charge two ore more batteries at once. The great thing with those is, that you can charge different batteries (different cell count and different capacity) at once. The bad thing is, the more channels they have, the more expensive the tend to get.
-
Parallel charging boards: A special board that allows you to attach multiple batteries, usually six, to the same charger. There are some things you need to consider when going this route, but I will explain all of them in detail, since this is the method we are going to look at in detail.

Good news for all Mobula7 owners: Happymodel has released an upgraded version (V2) of the Mobula7 frame.
They state, that this one should be able to take some hits before it breaks, actually, that it is nearly indestructible. This in fact is not true, it holds up far better than the original frame, but is still not up to par with something like the BetaFPV frame.
New batches of the Mobula7 will come with this improved frame by default.
The frame comes in two colors: Transparent or Transparent Black. It weighs in at 4.2g, so it is even lighter than the original frame that weight 4.8g.
Buy it from banggood.

This news just came in via Facebook. Nate Payne seems to have received a couple of 300mAh, 80C/160C graphene high voltage batteries from TBS.
They come with an XT30 connector and weigh in at about 20.39g. They are high voltage and thus may be charge up to 4.35V per cell. Thanks to graphene they have a high continuous discharge rate of 80C and a peak discharge rate of 160C.

The Tiny Leader is the first 3S capable brushless whoop. Definitely not your cheapest option out there but the frame is carbon fiber and plastic - pretty sturdy. The hoops can be swapped each on their own.
The Tiny Leader comes with a XT30 connector and you can power it with 1-3S. At least the ESC’s are specced for that - in reality you want to use 2S or 3S in order to use its full potential. Especially with the HD version you should go for 3S if you want to have some punch.
There are two different options regarding the camera. You can either get the version with a Caddx Micro F2 with 1200 TV lines that can be adjusted from 0° to 45°. Or you can get the HD option equipped with a Caddx Turtle V2 with 800TV lines and the possibility to record HD footage with your whoop - how awesome is that?
The video transmitter is switchable and outputs up to 600mW power - pretty impressive!

What are the best 2S batteries for the Beta75x?
Now that the Beta75x is out for a couple of months, we have quite an option regarding batteries. In this post I would like to showcase some of the available batteries and which performs the best.
In a previous article I talked about battery specifications you might want to take a look at this too, before continuing.
I will focus on the Beta75x option that comes with XT30 connector and thus use 2S batteries, further I will only showcase batteries that fit into the battery holder without modifications, so basically only 300mAh batteries.
Unfortunately, most of the options do not come with a XT30 connector and you will have to add it by yourself - but this is not all too hard if you know what you are doing, I will explain it a little bit later.

The Tiny Leader has been announced to be released in December of 2018. Definitely not your cheapest option out there but the frame will be carbon fiber and plastic - it looks pretty sturdy.
The Tiny Leader comes with a XT60 connector and you can power it with 1-3S. At least the ESC’s are specced for that - I can not imagine it really running on 1S, seems to be a little too heavy for that, so I think, the target battery will be a 300mAh, 3S battery
The cam will be a Caddx Micro F2 with 1200 TV lines and can be adjusted from 0° to 45°. The video transmitter will be switchable and will output up to 600mW power - pretty impressive!

The Trashcan has first of all an very interesting name - but luckily it performs better than the name suggests. This model is made by Eachine and was released in late 2018. The name was chosen by the community which explains why it is, what it is.
The Trashcan comes with two PH 2.0 connectors so you can continue to use your 1S LiPo’s that you might have for your brushed whoop. Similar to the Mobula7 you have the option to fly it with one or 2S. This makes it a perfect fit for flying in and outdoors.

The Tinyhawk is a very unique brushless whoop. First of all, the motors are facing the bottom and the props are thus pushing instead of pulling. This is a very unusual form factor of prop and for now you are stuck with the original Emax prop for this model - I am sure this will change in the future, so fans of this model will also get some different props to experiment with. Another thing to notice about the motors is, that they have bearings instead of bushings which is very rare in this form factor.
The Tinyhawk is 1S only with a PH 2.0 connector so you can continue to use your 1S LiPo’s that you might have for your brushed whoop. This makes it really great for indoors.
The cam is very well protected by the canopy, but unfortunately you can not adjust the tilt. The motors come with connectors so you can easily swap them, in case they break.

The Mobula7 is a great choice if you are on a budget. But do not be fooled, it is a good performer and has some great features that are missing even with the more expensive options.
This model comes with two PH 2.0 connectors so you can continue to use your 1S LiPo’s that you might have for your brushed whoop. Further you have the option to fly it with 1S or 2S. This makes it very versatile - fly it indoors on 1S and outdoors on 2S.
The cam is an all in one option, meaning that it is camera and video transmitter all in one small package. The cam tilt can be easily adjusted to your liking.
