SAFETY Management System
- Learning to use a Lithium battery - Mandatory Factory LIPo usage guidelines

The Safety Data Sheet is HERE MSDS SDS .
Battery powered aircraft require very precise training to be able to get the most from the battery "fuel".  Things to understand fully, include :-

  1. You must use a cell-by-cell sensor (not included) to monitor the minimum voltage of the lowest cell DURING FLIGHT - failure to do so will progressively reduce the capacity of the weakest cell in any pack leading to early VLC and risk.  Once weaken a cell can never regain capacity. Lithium batteries draw the most current from the cell with the lowest voltage and progressively demand more and more amps from the weakest cell - leading to a situation called "Cell-diving" where a weak cell rapidly losses voltage <3.0v - these instances occur in-flight under load - after landing a measured value may appear less severe - but if the inflight voltage dropped to 1.9v and then after rest is measured at 2.9v the real damage was done when the voltage dropped to 1.9v - 50% of the capacity of that cell can be wiped away in a single flight pushed to far
  2. Never use flight time alone - you must know each batteries individual capacity to run comparative flight times - this does not mean the new capacity but the "measured" capacity - To get the benefit of the full warranty you must use an inflight cell monitor and land before the lowest cell reaches 3.0v
  3. Number all your batteries and keep records of flight times vs capacity - regularly "cycle" the battery on an iCharger to determine its capacity.
  4. Never use any budget chargers" -  if the internal balance resistors are cheap/low grade or the accuracy of the device is not perfectly calibrated? it WILL risk imbalance damage to the cells over time - for this reason we only recommend iCharger brand HERE - change the default balance setting -> set it to "always" balance (not just at the end of the charge sequenece)
  5. If you over-charge any cell >4.2v you will cause a chemical fire.  READ BELOW all warnings !
  6. If you drain any cell below 3.0v you risk permanently damaging the chemistry in that cell.  There-after regardless of what you do it will have a reduced capacity for life in that cell.   
  7. If you store a LiPo battery flat at 3.0v or 3.2v per cell (so at 9.0v for a 3S LiPo) it's capacity will be drastically effected !!!!  - charge it back to storage voltage 3.8v per cell within 3 hours of discharge
  8. If you store a LiPo at full charge (4.2v) for more than 3-7days it's capacity will started to be effected and reduced and may puff - always store at 3.8v per cell
  9. The capacity in MAH is measured using an inline "watt-meter" or a icharger by cycling the battery cells between lowest safe voltage (3.0v on the LOWEST cell) and full charged (all cells on 4.2v balanced). Temperature can drastically effect capacity below 25°C  - you must use a LiPo warmer in cold winter conditions (or just keep one inside your down jacket until you are ready to use it) !! Anybody can fly and land with 50% battery power remaining, be conservative - that is fine - but seriously what is the point in carrying such a heavy battery for a short flight? - your safety margin is based on the quality of the "fuel" data you have at hand - so - To obtain and use this capacity you have to use "live" telemetry - We either use a dedicated cell-by-cell device for FrSky ; or for other brands like Futaba or JR or Spektrum we use a separate telemetry sender and Rx on the ground.  this enables us to know at all times the cell voltages under load. Using these voltages and "audio" voice advisory data coming from the Taranis we can safely fly right down to 3.2v on the lowest cell and land with only 5-8% of the power left.  Its not a problem providing you build YOUR systems monitoring skill to match the technology of the battery and understand the chemistry relationship to cell voltage.
  10. Using a stop-watch - secondary to a live cell monitor - If you don't have a cell meter or any telemetry your risk of damaging one cell will be much higher and outside warranty.  The old fashion system was to do a test flight at full weight AUW in the hover at 2m over soft long grass - and time it, on a stopwatch.  When the ESC's slow/shut show at VLC the quad would flop into the grass (usually 3.0v if set correctly for a multicopter) then you stopped the timer. However such a test actually damages 1 cell in the lipo immediately as the lowest cell will be much lower than the stronger cells in the dying moments.  That was your best options flight time in a crude way - it would usually be measured value, less 20% if you did power climbs or pumped the throttle or the sticks as this uses extra juice.  So if your test flight shut-down at 10 mins - you then set your Radio stopwarch to count back from 7 mins (giving yourself a 2mins reserve +1min to prevent damage to any weaker cell).  You repeated the test with a new LiPo. You landed at 7mins WHEN YOUR STOPWATCH ALARM ON THE FUTABA GOES OFF and then measured the cell voltages to double check and see what your margin is/was - you then take that lipo inside and drain it all the way down to 3.0v per cell and see what MAH was left in it?  The problem with this system is it breeds complacency - after a while you just fly blindly to 7 mins - next thing you have VLC and one of your lipos is ruined - Avoid this by numbering all your LiPos and keeping records of their capacity status.
  11. Using total voltage - Most radios with telemetry now have this ability to see a total voltage and show it or via iOSD - this is fine for non-lithium batteries - but is primitive for LiPo.  Knowing the total voltage does NOT predict any imbalance in the cells under LOAD. It also does not warn you when one cell is weak and "diving" - so use this method very carefully.
  12. Finally - the full-warranty method - Using Cell by Cell "live" telemetry.  If you own or plan to own a FrSky Taranis then the FLVSS is a MUST have item HERE.  If you have another brand of RC Radio like Futaba or JR/Spektrum then you need to run a 3rd party Cell-by-cell system.  These telemetry senders are connected to the LiPo balance port.  they transmit back to the ground, the cell voltages during flight via "telemetry".  For Taranis we activate the Voice function on the Tx and set the audio to call out the lowest cell voltage every 20secs (can be muted by a switch) - at 3.8v we know that 50% of the LiPo battery is used/remains - at 3.4volts we start wrapping ops up and return close to home - planning to land at/by 3.2v on the LOWEST cell.  In a post-flight check this shows up as 5-8% remaining with a good cell meter.

Warranty

We stand behind our CarbonBird LiPo when used correctly with a live in-flight cell monitor and charged correctly Our 120 day warranty (read this page in full) relates to proper informed educated and due-care normal use, normal discharge as per a cell monitor inflight >3.0v on the lowest cell, NEVER less than 3.0v in-flight under load, and normal balance charge and storage at 3.8v per cell only.  It excludes any abuse or damage from ignorance, over draining any cell below 3.0v, storage at any voltage other than 3.8v/cell or accidental/crash, puncturing of a cell or forced discharge

NOTES before use - You must : - 

  1. NEVER drain below 3.0v per cell in flight - specifically the lowest cell - total voltage is outdated and irrelivant - You MUST use cell-by-cell monitoring in flight.  Once taken below 3.0v your cell will suffer permanent severe capacity loss and we can detect this event due to an immediate change to the internal resistance  - once drained <3.0v then that cell will PUFF up from the damaged chemistry due to over discharging fault by user - this cannot be undone - even if charged again - so after being run down below 3v per cell you will damage the battery - we will test any returned battery for this to see if it has been drained or lost capacity from mis-magament.
  2. Never assume a fixed flight time and never fly blindly to this time - if the aircraft reaches VLC (voltage low cut-off) it will shut down the ESCs rapidly resulting in a crash risk - however this event will take a savage toll on the lowest cell in that battery as the voltage can dive in the weakest cell in seconds - This type of problem does not happen if capacity is checked regularly and a cell moniot is used and the copter is landed by 3.4v-> 3.2 in an emergency
  3. ALWAYS Store your LiPos at 3.8v per cell balanced using an icharger - Choose LiPo Storage MODE.  Set Balance charge to ALWAYS in the charger settings prefs.    symbol-fire-explosion-risk.jpg
  4.  DANGER - FIRE !   NEVER charge above 4.20 v per cell or set to the wrong mode - LiPo batteries WILL combust & burn fiercely if over charged above 4.23v , or if charged on an incorrect MODE setting (ie a setting other than LiPo - triple check you set the charger to LiPo BAL MODE - Max 4.20 volt per cell) - You must use a proper quality charger like iCharger - a cheap charger will also void your LiPo warranty - Any warranty claim with more than 0.3v cell imbalance will not qualify - you must balance your packs.  make sure its set to LiPo and balanced plug used and used temperature cut off as well. NEVER LEAVE the charger - stay with 2m and observe the charge voltage is less than 4.20v.  ALWAYS use the TEMP probe safety cut-off as well.  This will provide a 2nd level of safety cut at <36°C.  Also, Never short the wires - large current flows of 100amps can cause electrical fire if shorted.  For travel use the original packaging the battery was shipped in.
  5. Never charge any LiPo in SERIES - Series charging will damage your LiPos within days-weeks as it does not take into account different batteries and any mis-match in impedance results in the orphan cell with the highest impedance being further damaged in a group of batteries - ie if you mix 2  x 3S packs and try to charge them as one 6s pack - you will void your warranty.
  6. Any DOA claim must be made within 24 hours of signing for delivery - As soon as you receive the LiPo please Check all Cells - its voltages are balanced - cycle the battery to determine it's capacity and number each battery
  7. Prior to making and Warranty claim please read the technical limitations of Warranty Document
  8. XT60 connector - if very tight - use a small amount of Lanoline spray internally on the male plug (ESC side) - clean away excess - the same as you use on the ESC/Motor push connectors - lubrication = problem fixed - if still a problem , observe where the greatest rubbing is occurring from slide marks - then use 200grain wet-n-dry (with lanolin spray for lube) and gently smooth that high point - generally one squirt of spray solves all issues - - NEVER use pliers! extreme risk of short circuit! Grip the connectors firmly between forefinger->thumb.
  9. Never puncture a cell - that puctured cell will loose capacity - a large hole of 3-5mm will cause the cell to loose all capacity in 24 hours - a small pin hole will result in 50%-70% losses in a week from that cell.   Cells can be accidently punctured by sharp objects such as pins or virgin carbon which has not been dulled by a diamond file

  1. Preliminary tests

    Posted by Millard Berry on 11th Jan 2016

    Weather has limited flights, but first tests of this battery look good. With a Vampire (gimbal, GoPro, FPV, LED's) flying aggressive and hovering:
    16 min., 13.5V minimum under load at end; air 29F, wind 11mph.
    14 min., 14V minimum under load at end; air 43F, wind 7mph.
    I like these batteries.
    To order them you need to communicate with MultiWii folks about shipping arrangements.
