New Battery- Save ~ 7 lbs ( Equivalent to 1.5 to 2.5 more HP !!! ) Should I go for it?

My current battery is about 4 years old.  Being in the trike, it is not a daily driver so it gets left for periods of time.  It's about at the end of it's useful life and needs replacement.  Having weighed everything that goes into the trike, I was REALLY surprised to see how fast it all adds up.  So, now I am pretty particular about weight in the trike, and try to keep it to a minimum where I can.  Of course losing 20lbs myself would be a great way to help!!! ;)  But, let's be realistic ; )    The BioniX 15M fortunately carries a net additional 50lbs- which is quite a lot of XC equipment, or extra oomph for big passengers and high density altitudes.

Most of this data / quotes are from other sites:

In motorcycles, mathematically they say every 5-6 lbs of weight savings = 1 HP Gain.  At least that seems to be the rule of thumb.

Per one dealer, AntiGravity SuperLight,   and    Full Spectrum Power Pulse Batteries (P1, P2, P3), are excellent and the dominant brands.

(No fires were mentioned  ;)   contrary to the 787 Dreamliner -- but, as seen below, these batteries have internal circuitry to stop excessive drain causing heat-- perhaps that was too expensive / complicated for the 787's ?! )


This is what I have currently:  ODYSSEY DRY CELL BATTERY SBS J-16

  • The battery weighs less than 15.4 pounds.  (per the website, "weighs less than" ... probably means 15.39)
  • 5 second 80°F (27°C) cranking amps to 7.2V: 680 amps
  • CCA @ 0°F (-17.8°C): 220 amps
  • CA @ 32°F (0°C): 300 amps
  • HCA @ 80°F (27°C): 370 amps
  • Reserve Capacity: 25 minutes @25amps
  • Terminals: Brass female for M6 stainless steel bolt

This is what I'm considering:  Pulse 3 Battery

  • Save 7 lbs. on a 1200cc bike
  • 390 cranking amps / 7.5 amp hour capacity
  • Weight: 2.2 lbs.
  • Common Applications include: 1300cc inline 4-cylinder sportbikes; 1200cc twins; Drag racers using total-loss ignition systems
  • Fully compatible with your motorcycle's stock charging system. We recommend using the Pacemaker or CV Charger with all Pulse and Genesis battery systems, which are designed for lithium cells. Standard chargers will not work properly with lithium cells. We also recommend disconnecting your Pulse or Genesis battery when the motorcycle will not be used for an extended period of time (more than 3 days) to prevent self-discharging which may permanently harm your battery.
  • The Pulse P2 features the finest A123 Systems cells for consistent performance and balanced power. Each set of cells is enclosed in a Valox composite case (stronger than ABS plastic, with heat and fire resistance). This case is super tough, yet light weight and compact to meet the demands of motorsports. Pure brass terminals are specially machined for the case, and connect to an Integrated Protection Circuit. This provides automatic current shut off if a short circuit is detected, or a forced discharge is detected. This protects you, the battery, any your machine from a potential hazard. No other battery offers this combination of lightweight, power, and safety
  • All Full Spectrum Power Pulse batteries include a 2 year warranty.

      Lithium-Fe                 Lead                           Difference       

  • 390 ~CCA             220 CCA               =     170 CCA in favor of Lithium (CCA are approx for Li-Fe)
  • 2.2 lbs                 < 15.4 lbs             =     13.2 lbs in favor of Lithium
  • $269                   $190 + ship          =      $79  in favor of Lead  (but lead shipping will be a bit higher)

       + $49   for special balancing charger for Li-Fe

        (may only be good for specific manufacturer brand)

        So, about $130  more for the Li-Fe     ($49 charger +$79 price)


Additional Pluses for the Lithium-Fe are:

  1. Store better in cold than in heat. Recommend leaving in the garage all winter.
  2. Have very low discharge rates when no parasitic drain present
  3. Potentially have high(er) CCAs
  4. Lighter weight
  5. Smaller space
  6. Can actually recover for a second chance when over-cranked and used.
  7. Contrary to OP's advise, they have no negative points if used with GPS, radar, stereos, or other accessories. That's what the charging system is for. Just make sure accessories are shut off when the engine isn't running. See first negative below for what the real problem is.


  1. Unlike AGM or other lead acid batteries, they do not recover at all if let drop below 11.2v. They don't chemically have the equivalent of "de-sulfiding" like a traditional lead acid battery has.
  2. Due to design, they need balancing chargers periodically, to make sure individual cells are fully recharged. Some are expensive, and some are cheaper. Plain old Battery Tenders work up to a point, but can't do the job of a balancer once or twice a year.
  3. See above, requires higher attention. Can't be neglected. If you do, you lose a much more expensive battery and possibly the balancing charger you should have bought with it.
  4. Lastly, my experience is there is no standard balancing charger plug in, from brand to brand so once you choose a brand, you may be locked in to that brand unless you don't mind losing the charger as well.


So, my thoughts are:

  1. Extra Maintenance-  if there are no drains, this battery should last longer than the lead.  It does require a special charger (extra $70 ) to balance the cells twice per year-- I can do that.
  2. Fire !!!  My battery sits right in front of my ABS gas tank- behind my back / between passenger's legs.

          This risk is tempered by the internal circuitry.  I didn't see any motorcycle reports of fires.  I could put some aluminum / flame retard material between the battery and tank.

Do we have any continuous / vampire electrical drains in the trike?  When the key is shut off, there is no power drain right?  No maintenance power to the Enigma (it has little internal watch batteries) right?

They are sold by Aircraft Spruce  and  CPS (California Power Systems) (now under same company, but formerly an independent California Rotax Specialist).

    I was having similar thoughts a while back, until the 787 nonsense.  Those batteries had circuitry to prevent overheating and fire - the plane was certified because the batteries were not going to experience thermal runaway more than once every 10 million flight hours.  After it happened twice in 50,000 hours they got grounded.

    I didn't know enough to tell how well the lithium batteries being sold for motorcycles were designed, and since the battery on the Tanarg is located a) about a foot beneath my ass and b) directly next to the plastic gas tank it seemed like too much of a risk.

    See the information listed on this POLL regarding Lithium Iron batteries and safety.

    Lithium Iron  (LiFe) is completely different from Lithium Ion.

    The 787 and exploding laptops use Lithium Ion.

    There is plenty of data on exploding / overheating Lithium Ion,  but I can't find any examples that show that LiFe is any less safe than a standard Lead Acid.

    It appears that special "balance charging" only needs to be done about once per year or so.  So, Ken (who's been loving his LiFe battery) is going to share his charger with us when we meet up.  Saves us $80 each on the Shorai charger.

    Ken, Tom, Craig, and now Henry & I are using these batteries.  Craig for the longest (a couple years I believe, but he didn't let anyone know ...)

    Both Ken & Tom report that this baby really cranks the engine over well.  I was also surprised to here Ken, who was working on his engine some and cranking it over a bunch, had no problem on multiple starts.  No fade.

    These batteries have a reported excellent shelf life, with virtually no power loss-- however, if you have a small "vampire" draw (like a clock, etc), these batteries will go flat much quicker than lead acid!!!  These batteries are like sprinters, they punch hard (and start VERY well), but do not have super long endurance.

    An interesting side benefit is that in the cold, these batteries need to warm up chemically before they can start well.  So, you can turn on your flight computer or a light, etc to get the internal chemical reactions generating heat.  Or you can crank the engine over.  I used to do that anyway-- I'd hand prop the engine to move oil up into the engine and "burp" it, then I would turn it over without starting it using the battery right before real start-up.  I thought I'd have to stop that with the LiFe battery, but, especially when it's cold and oil doesn't want to move well, it will actually HELP to use the battery to turn the engine over and move oil into the engine.
