This however is assuming that the C rating on the pack is accurate. Mah capacity x C rating / 1000 = output potential ( current ), measured in amps.įor example, a 10C 5000mAh pack can output 50amps, and a 20C 4000mAh pack can produce 80amps. Most lipos have the C rating listed in their specs, but this doesn't actually tell you how many amps the lipo can output, there is a very simple sum however: This is a measure of how much current ( in amps) the battery can output before it will overheat and become damaged. The C rating is also known as the discharge rating. A Velcro strap is a simple way to allow taller packs to fit, but you are still limited in regards to length and width, unless you opt for an aftermarket chassis. The very simple method of doing this is to just measure the length and width of the battery trays, and the height available with whatever hold-downs you have available. Since size is linked to capacity, it is worth ensuring that you can actually fit the lipos you wish to use in your truck. The new Emaxx has more room for lipos compared to the old model, but aftermarket solutions are readily available to allow larger packs to be fitted to either chassis a velcro strap & dremel can do magical things for your battery options. Typical lipo packs are sold in 4000,5000,60mAh sized packs, with the optional battery hold-downs being required for the larger sizes. The only downside is that larger mAh cells are also larger in size, and therefore weight (they are still only half the weight of Nimh cells it is worth noting however). Lipo cells in general are available upto about 5000mah in capacity, beyond this pairs of cells are used in parallel to increase the mAh, and therefore the runtime. To run 5s lipo you merely require a matching 2s and 3s lipo with the same mah capacity & C rating, and of the same brand & age.Ĭapacity is directly linked to runtime- the higher the capacity (measured in milli-amp hours, or Mah) the greater your runtime will be. However, many users ( myself included ) find that 5s is the sweet spot for a nice mix of power and speed. In the Brushless Emaxx and Erevo you can use a maximum of 6s lipo, usually in the form of a matching pair of 2s or 3s lipos. To do this, you must connect the 4s lipo to the BEC side of the Evx2, and then use a jumper to short circuit the un-used battery input leads. It is entirely possible however to use a single 4s lipo, which may be desirable if you have an aftermarket chassis or have converted a Nitro model to Electric power and have limited room. It is best to use a pair of matching 2s lipos ( that means they must have the same C rating, Mah capacity and be the same brand & age etc ) for space and weight reasons ( a pair of 2s lipos in series will give a total of 4s lipo ) & due to the chassis layout being intended for a pair of packs, rather than one large one: In the stock Emaxx and Erevo, the Evx2 is equipped with a pair of battery input leads, each pair intended for use with a 2s lipo (7.4v), giving a total of 4s lipo (16.8v). ![]()
