  • Unplug battery connector using nail, don't pull cable.
  • Battery is glued to main board (PCB) by very strong adhesive, so it cannot be pulled out, because it will (for sure!) destroy the SD card holder. Battery must be rotated around axis normal to PCB, what will produce shear stress to adhesive and PCB components, which will break adhesive, but not PCB.
  • Put the new battery same way and on same place, footprint has both batteries the same, only thickness is different. Correct placement is symmetric between two pillions for screws.
  • Connect the new battery to PCB pushing its connector to PCB.
  • Place rubber ring by raised collar facing to PCB.
  • Place new back cover, the first arrange USB connector into its hole, than clap the opposite side.
  • Put screws back or use new ones, if they are worn. Use torx tool for best results.

Bad battery health

I shipped all my paragliding equipment from japan to Sri Lanka, which took three months. Afterward, when I tried to switch on my sky-drop it was not working. I purchased it just one month before I left Japan. Finally, I opened up the sky-drop and found that my double battery was swollen up. It was only two line connection which does not have a battery health controller. It is better if sky-bean can use a better battery.<br /> Then I changed the battery to a compatible phone battery and it is working fine. Check images attached

Reply from SkyBean:
Hello,<br /> <br /> sorry to hear about your issues. This should not happen - however it is hard to say if it was not under some extreme conditions when traveling for 3 months from Japan to Sri Lanka. Too hot or too cold temperatures, high pressure, overcharging, manufacturer defect or deep discharge can cause the problems.<br /> I see you were able to exchange the battery by yourself. What we can do for you, is to send you a spare double battery. If you are interested just write me to your shipping address.<br /> <br /> Take care

Second time around

This is my second double battery kit, as the first one only lasted for two years... One of the cells in the first battery swelled so bad that it actually cracked the back casing. Pleased to see that a new slimmer mould is used for the casing so the difference is not so big between single and double battery. Easy to install and keeps the instrument working without charge well over a weekend of flying!
