E-Maxx Battery Recommendations (Part 1)

It is important to know what battery packs should I buy and how to charge them? There are so many battery packs available that it is hard to make specific brand recommendations. However, here are a few points to keep in mind about batteries and charging.

If any battery pack gives higher the mAh rating, the longer the battery run time. That is, a 3000 mAh battery pack will provide with twice the run time of a 1500 mAh battery pack. Battery packs with 2400, 3000 or 3300 mAh ratings are expensive to purchase. If cost is an issue, 1500 to 1800 mAh NiCD packs are very economical to purchase and work well in the E-Maxx The battery packs should be 7.2 volts and have a standard Tamiya connector as well and should be assembled with 6 sub-C sized cells.

The 6-cell NiCad or NiMH battery packs should be charged between 3 and 5 amps on a peak detection charger designed for both the packs. For backyard bashing or general use, a 3 to 4 amp charge rate is recommended. For racing, a 5 amp charge rate is recommended, but lower charge rates are fine too. If recharging the battery packs is required then they should be allowed to cool down completely before any re-charging is done else the packs would be damaged.

While storing, NiCad battery packs should be completely discharged before they are recharged or stored to maintain optimum performance. On the other hand, NiMH battery packs need not be to be completely discharged before they are recharged, but it is recommended that NiMH packs be fully discharged every 4 to 8 weeks. If NiMH packs are not going to be used for more than two weeks they should be partially charged 30 to 50% of their maximum capacity. For long-term storage of NiMH packs it is suggested that they should be fully charged. The easiest way to discharge your battery packs is to simply run them in your E-Maxx until the truck slows to a crawl.
