Description   Build your System Voltage by putting these Lithium Iron Phosphate "Cells" in Series. The 200 Amp/Hr Batteries have a C3 Continuous Rating of 600 Amps.  These Cells come with connection "Straps" and Bolts to put these in series.   There are many different voltage and ampere configurations. We have come up with a simple module that can be easily formed into the pack that you desire.  These modules are 3.2VDC nominal.  The sizes are 2.2" by 8.6" by 13".  They are not orientation sensitive, install them any way you want.  You should use "3 volts per cell" to calculate the number of Cells you need to assemble your "System Voltage".  They are maintenance free, so put them in and forget about them.  Each module weighs 15.5 pounds each.   Contents A fully charged and balanced Li battery pack will remain balanced as long as you do not exceed 3C in discharge. Lithium batteries are very obedient.  They will continue to provide current if you want it, even if it means their death and destruction.  For this reason it is very important that you monitor the charge on the groups at all times.  A good tool for this is the PakTrakr.  A 12V group of Li should not be allowed to fall below 10.8V, set your discharge cut off at this point.  This allows a level of safety, a margin.  There is a specific known level at which a Li will not recover, and we know what that level is....but we are not going to tell you because someone out there will set their cut off at .0001VDC above that point and then wonder what happened.  Set your cut off at 10.8VDC per 12VDC pack.  That is 2.7VDC per cell, a comfortable margin. These "Lightning Bolt" batteries will remain balanced as long as you do not exceed 3C in discharge.  If you exceed 3C in discharge they will become imbalanced over time.  This will not damage them but it will require that they be individually re-balanced to regain their full capacity.  To avoid the hassle of taking your packs apart to balance them we recommend that you employ automatic balancers in your packs.  The absolute best one out there is the BatteQ. You may use almost any pure DC isolated charger to charge the packs if you employ the PakTrakr and BatteyQ technology in your vehicle.  Set your upper limits at 3.8VDC per cell, and your lower at 2.7VDC per cell and you are all set. Lithium batteries do not like to take a charge below freezing.  I mean, think about it, would you?  For both of you who live where it is below freezing all of the time, install  a thermostatically controlled heating blanket under the pack to keep it above freezing.  For the rest of us who live in areas where liquid water exists at least for a short period every year, here is a tip.  Li batteries will discharge way below zero degrees F, and when discharging they will generate heat to well above freezing.  When placed on a charger Li batteries will generate heat well above freezing.  So.....when you get home from any drive, any time of the year, your batteries are warm enough to take a charge, and will stay warm until fully charged if you plug them in as soon as you park the vehicle.  A little time management goes a long way, and the best time to plug in your charger is as soon as you get home. Li batteries love to be kept on a charger, they have no memory.  Our current battery packs have well over 2000 charge cycles in them.  This does not mean that you can only plug in the charger 2000 times, it means that you can fully deplete them and fully charge them 2000 times.  If you only drive 50 or 60 miles a day on a 200 mile pack, and plug it in every day, you are going to get about a gazillion charge cycles before the pack falls to 80 percent capacity. Li packs do not require water cooling, air works just fine.  They do generate heat, and you do have to move that heat away from them.  The air movement created by the vehicle during a drive is sufficient to cool the packs.  Route this through your packs.  A properly ventilated Li pack will settle in at about 114F. Li batteries do not vent gasses as long as 3C in discharge is not exceeded.  Some venting can occur above that.  The venting gases are non-toxic. Follow the few simple rules of Lithium and they will last a lifetime.
