Balancer Wires DIY repair (TP2100)
Balancer wires came loose - DIY Repair guide
Just to share my little experience on how I re-soldered the balancer wire back to my Lipo (TP2100).
Special thanks to brother ‘Moveon’ for his tips and guidance
Please observe all Lipo handling safety when attempting this repair as Lipo can be dangerous!
Step by step Photo attached for your reference:
(1) Photo showing one of the white balancer wires came loose from battery
(2) Cut the transparent shrink rap till the yellow label is exposed
(3) Slightly peel up the yellow sticker so that the brown insulation tape is exposed. Then peel up the brown insulation tape:
(4) Carefully cut open the inner insulation layers
(CAUTION: Make sure not to short any of the contacts!!)
(5) This is how the inside looks like. Each wire is soldered to a tag and individually insulated.
(6) Identify the tag where the loose wire came from
(7) Carefully slit open the individual insulation and prepare it for soldering
(8) Pre-tin and solder the loose wire back to the tag:
(9) Insulate the repaired contact (individually) with a new insulation tape:
(10) Arrange the red wire back to its original location and tape down with fibre tape
(11) Arrange the black wire back to its original location and tape down with fibre tape
(12) Test with a balancer to check if the connections are good
(13) Re-tape the brown insulation tape back to its original location
(14) Close back the cut transparent shrink rap and tape with scotch tape. If you like, you can actually by those 60mm transparent shrink rap from LHS and change this portion of the shrink rap.
(15) This is the completed repair.
Notice that the balancer wires are now taped onto the side of the battery to avoid accidental dislocation due to handling. This is a good practice.
Warning: If you are not sure, don’t try. Lipo can be dangerous!
