WHAT TO DO AFTER I RECEIVE MY AXXIS VOLTAXX CELLS
After you unpack your cells you are ready to solder them into a pack.
Axxis Racing does not recommend cycling newly assembled packs (cells) with a charger/discharger. During the HES Enhancing process, the cells were cycled numerous times and are already equalized and matched to the highest standards. By cycling them on a charger/discharger you run a 50% chance of lowering the quality of the cells and overall performance will diminish.  Once assembled, VoltaXX packs are ready for immediate race use. Just follow our charging and maintenance recommendations.
You will notice that the batteries will get better after 2-3 runs. Under no circumstances you should allow your battery pack to DUMP at any time (this applies to competitive racers).

ASSEMBLING YOUR IB or GP BATTERY PACK
Let us start by letting you know that a majority of persons damage their cells while soldering them. This damage can be from total destruction to minimal capacity loss. Great care should be taken while soldering in order not to damage your cells. It should not take you more than 5 seconds to solder each battery terminal. More than that and you run the possibility of irreversible cell damage. IB cells are very sensitive to overheating while being assembled.
The first and most important thing is to make sure you have the right kind of soldering iron. YOU need a soldering iron with a minimum of 60 watts, preferably, get a 100 watt iron with a 1/4" chisel tip. This will make the entire soldering process smoother and you will have less chances of damaging your cells. Great results can be achieved if you use the right equipment.
So lets start: Using 600 grit sandpaper, Scotchbrite, or a Dremel sanding drum, lightly sand the cell ends (top+ bottom-) until they are dull. Afterwards clean the ends with rubbing alcohol or motor cleaner to get all residue of the cells.
Align all your cells and apply a small amount of SHOE GOO between them to build a strong pack. Allow an hour for to set. Thereafter, mount your cells in a soldering jig. Prepare all your supplies and have everything ready and next to you as you want to do the soldering job as fast as possible.
Once the battery pack is in the soldering jig clean again all your contacts with motor cleaner or alcohol prior to soldering (both the battery and solder bars).
DO NOT TIN THE CELLS ENDS OR BATTERY BARS. Most solder has lead, and lead is a terrible conductor. We recommend Axxis 4% Silver Solder as it has a very LOW RESISTANCE. Apply a small dab of Axxis FLUX to the cell end and battery bar.
Place a battery bar across two cells, melt a modest amount of solder to the tip of a hot soldering iron (BB sized - 4-6" of solder). While holding the battery bar tightly against the cell, apply the iron tip to the battery bar at a 60° angle. The solder should immediately cover the 3 battery bars holes and flow around the bar to the cell. Remove the iron while continuing to apply constant pressure on the bar until the solder sets. If the solder does not flow smoothly within 3 to 5 seconds, remove the iron immediately. Wait for the cell to cool down to room temperature before attempting to re-solder. Do not hold the soldering iron to a cell for more than 5 seconds. Serious cell damage will result! After obtaining a good solder joint, repeat for remaining cells. If at all possible, wait a few minutes to let the batteries cool down before you solder the opposite sides of the cells. This will keep the overall cell temperature down and your batteries will perform better.

CHARGING YOUR IB3800's
Axxis Racing does not recommend cycling newly assembled packs with a charger/discharger.
During the HES Enhancing process the cells were cycled numerous times and are already equalized and matched to the highest standards. By cycling them on a charger/discharger you run a 50% chance of altering the overall battery pack quality.  THE BATTERY PACK PERFORMANCE AND POWER WILL GO DOWN.

Charge with a NiMh compatible charger that utilizes a constant current mode. Check your charger’s operating instructions for specific recommended charger settings. If there are no recommendations and you are not sure at what peak detection level to set your charger, start at the lowest setting and adjust from that point on if necessary. A digital temperature gun can help you get the right setting. Take a temperature reading at the TIME the PACK PEAKS OUT, the pack temperature should be between 125° and 132°F. If the temperature is bellow 125°F adjust your charger by going up on the peak detection level. Peak charging temperatures above 140°F will deteriorate pack performance and operating life..

RACE USE: If done correctly an IB3800 NiMh battery pack can be raced/used up to three times in one day without pack damage.  After the heat, remove the pack from your car and discharge to 0.85 Volts/ cell if on a tray, or at 0.9 Volts/cell as a pck.   If using a discharger like the one on your charger we recommend to discharge at 10-20amps.  After that, you should place your pack on an equalizing board that will discharge your batteries individually at a rate no higher than 4 amps and will get the batteries to their optimum levels.  We recommend a safe cut-off of 0.50 Volts.   Battery packs should be allowed to cool down before they are re-charged. We recommend using a fan to cool your batteries.
For competitive racing we recommend that the pack you will use for the MAIN be given enough time to cool down (2-3 hrs) before re-charging and do not use it more than once before the MAIN. We have found that many times the second charge will develop a little more power and the time loss is not significant with the VoltaXX packs.

MAINTENANCE DISCHARGING FOR IB and GP cells
A discharge rate of 15 to 20 amps is a good discharge rate that will not harm your batteries. Discharging at rates above 25 amps should only be done with the right equipment and cooling methods. High discharge rates generate extreme heat and heat is the main cause of battery failure. High discharge rates should only be used for testing and not as a maintenance procedure. Repetitive discharging at high rates without proper cooling will destroy your cells. 
You should use an equalizing discharge board like the Axxis EQ+ that will equalize your cells at the right current level and will not allow your cells to over-discharge (0.50V cut-off). This process will keep your batteries at their best performance.  Over-discharging IB cells is harmful and you will loose performance and overall power.  Previous IB batches were much more sensitive to low voltage discharging.
After a race day, discharge your packs to 0.9v/cell at 10-20 amps, let the pack cool down and then charge with only 1300mah.  This will keep enough charge on your pack to prevent the self discharge characteristics of NiMh batteries to over discharge your pack and cause cell reversal.  The night before you will race, discharge your pack again to 0.9v/cell at 10-20 amps; thereafter, tray your pack with a cut off level of 0.50 volts (at no more than 5 amps). Do not allow the cells to fall below 0.4 volts.  If using any of the Axxis Racing trays, they are programmed to equalize the IB3800 to the right level and at the right current. 
If using an Integy 030, be carful not to allow the cells to overdischarge.  On the 030's, the lights come off at 0.45V
Axxis Racing has a conversion kit for the 0-30 that sets the cut off level at 0.85 volts/cell.  This will keep your cells in a safe discharge area.
