MOBULA7 and Trashcan Upgrade: Convert your 1s batteries to a true 2s

Both the Happymodel Mobula7 (review) and Eachine Trashcan (review) both come with 4 x 1s batteries that are designed to be used in series 2 at a time with a fiddly ph2.0 series connector. This introduces a lot of resistance in the power circuit and resultant voltage drop under load which shows as battery sag. It is easy to upgrade to a true 2s JST connector as I've shown in this blog or a XT30 if you'd prefer. Although 2s 300mah batteries are not expensive it does feel wasteful just leaving the old batteries to die. This article covers how to convert these or any other 1s cell into a 2s battery and is scaleable up to 6s!

This is the fifth article in my series of HappyModel Mobula7 upgrades, many of which can be used for the Trashcan too. Also to come are:
  • Swapping to a much more durable frame​
  • Improving the battery connector for more power
  • converting to run 'props out' 
  • tuning betaflight filters more specifically for brushless whoops, 
  • propeller upgrades. 
  • receiver range improvement​
All links will be updated here when completed. Many of these I've completed the work and am testing at present - it's starting to feel like a more complete little quad now. If you're looking for my review of the mobula7 including setup it can be found here
A Word of Warning
Lipo batteries - even these tiny ones - have a lot of power. Anytime you modify you run the risk of rapid discharge (shorting) which generates heat and possible worse. Only do this mod if you are confident around electronics. Please wear eye protection at a minimum and work in a well lit space. Just go buy the 2s batteries if you are unsure at any point.
Getting prepped
As well as having a well lit area and a good soldering iron, solder and flux (see my article on budget tools here) you'll nee the following items:
  • 2s balance connectors with silicon wire like these: JST-XH 2S LiPo Balance Cable
  • JST female plugs with silicon wires like these: 5PCS Amass 20AWG 10cm JST Male Plug Cable 
  • or XT30 female plug with silicon wire like this: XT30 Connector To 18AWG Cable 100mm
  • 30mm wide PVC heat shrink tubing like this: 5M Flat 29.5MM 18.5MM PVC Heat Shrink Tubing
