100 Amp Hour 3.2 Volt LiFePO4

100 Amp Hour 3.2 Volt LiFePO4 Battery
Lithium Iron Phosphate (LiFePO4) Batteries - 100 Amp/Hr Batterieshave a C3 Continuous Rating or 300 Amps and a Peak of up to C11 or1100 amps. These Cells come with connection "Straps" and Bolts toput these in series.

There are many different voltage and ampere configurations. Wehave come up with a simple module that can be easily formed intothe pack that you desire. These modules are 3.2VDC nominal. Thesizes are 2" by 6.3" by 11.1". They are not orientation sensitive,install them any way you want.

You should use "3 volts per cell" to calculate the number ofCells you need to assemble your "System Voltage". They aremaintenance free, so put them in and forget about them.

Each module weighs 7 3/4 pounds each.

We offer a 30 day Money Back Guaranty and a one year replacementwarranty on these Batteries. If you have a "BMS" System (notincluded) we offer a three year warranty.

A fully charged and balanced Li battery pack will remain balancedas long as you do not exceed 3C in discharge.

Lithium batteries are very obedient. They will continue toprovide current if you want it, even if it means their death anddestruction. For this reason it is very important that you monitorthe charge on the groups at all times. A good tool for this is thePakTrakr. A 12V group of Li should not be allowed to fall below10.8V, set your discharge cut off at this point. This allows alevel of safety, a margin. There is a specific known level at whicha Li will not recover, and we know what that level is....but we arenot going to tell you because someone out there will set their cutoff at .0001VDC above that point and then wonder what happened. Setyour cut off at 10.8VDC per 12VDC pack. That is 2.7VDC per cell, acomfortable margin.

These "Lightning Bolt" batteries will remain balanced as long asyou do not exceed 3C in discharge. If you exceed 3C in dischargethey will become imbalanced over time. This will not damage thembut it will require that they be individually re-balanced to regaintheir full capacity. To avoid the hassle of taking your packs apartto balance them we recommend that you employ automatic balancers inyour packs. The absolute best one out there is the BatteyQ.

You may use almost any pure DC isolated charger to charge thepacks if you employ the PakTrakr and BatteQ technology in yourvehicle. Set your upper limits at 3.8VDC per cell, and your lowerat 2.7VDC per cell and you are all set.

Lithium batteries do not like to take a charge below freezing. Imean, think about it, would you? For both of you who live where itis below freezing all of the time, install a thermostaticallycontrolled heating blanket under the pack to keep it abovefreezing. For the rest of us who live in areas where liquid waterexists at least for a short period every year, here is a tip. Libatteries will discharge way below zero degrees F, and whendischarging they will generate heat to well above freezing. Whenplaced on a charger Li batteries will generate heat well abovefreezing. So.....when you get home from any drive, any time of theyear, your batteries are warm enough to take a charge, and willstay warm until fully charged if you plug them in as soon as youpark the vehicle. A little time management goes a long way, and thebest 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 inthem. This does not mean that you can only plug in the charger 2000times, it means that you can fully deplete them and fully chargethem 2000 times. If you only drive 50 or 60 miles a day on a 200mile pack, and plug it in every day, you are going to get about agazillion charge cycles before the pack falls to 80 percentcapacity.

Li packs do not require water cooling, air works just fine. Theydo generate heat, and you do have to move that heat away from them.The air movement created by the vehicle during a drive issufficient to cool the packs. Route this through your packs. Aproperly ventilated Li pack will settle in at about 114F.

Li batteries do not vent gasses as long as 3C in discharge isnot exceeded. Some venting can occur above that. The venting gasesare non-toxic.

Follow the few simple rules of Lithium and they will last alifetime.
