Pulse Batteries feature a warranty against any defective batteries we manufacture, and warranty all manufacturer related defects or flaws. Pulse insures that all packs are properly balanced, but please be sure to check your Pulse battery upon arrival for any faults, such as low voltage, cell imbalances, solder joints, and any other such defect. If any such flaws arise, Pulse will be sure to cover all claims within a period of 60 days; all claims after the 60 days period of purchase will not be subject to warranty, so please be sure to carefully inspect your new Pulse battery upon arrival.
Pulse Batteries – Your Questions End Here.
Have a question regarding Pulse batteries? We have assembled a spread of many questions that are asked about Lithium Polymer batteries, along with Pulse batteries as well. Of course, if you don't find your answer here, feel free to drop us a line, as we are always happy to help.
Q: What is a "C" rating, and what does it mean to me?
A: "C" ratings are categorized in (2) areas – discharge rate, and charge rate. Pulse Batteries are typically rated at 35C, 45C, and 65C discharge rates – this is based upon how much amperage can be delivered, or in simpler terms, how much power your battery has to give. The higher the "C" rating, the more power the battery can give out.
As for the charge rate, Pulse batteries are rated at 5C, which means they can be charged 5 times faster than a conventional 1C Lithium Polymer battery. In short, Pulse batteries can be charged at very high rates of power for rapid charge times, eliminating the wait time of conventional batteries that are limited to 1C.
Please note that some specialty packs (for example transmitter and receiver packs) may have lower charge and discharge ratings.
Q: What is mAh, or capacity, in terms of Pulse batteries?
A: "mAh," short for milliamp hours, is a reading of capacity, or how much energy the battery is able to store. mAh, or Capacity, directly relates to flight time, and indirectly relates to power output, as higher capacity batteries also have greater amperage to deliver, when asked to do so.
Q: How long does it take a Pulse battery to charge?
A: Considering Pulse batteries are rated at a 5C charge rate, if your charger can deliver the necessary amperage to charge at 5C, charge times can be as low as 15 minutes, depending upon the charger being used.
Q: How can I determine how many amps my Pulse battery can be charged at?
A: To determine how many amps you can safely charge a Pulse battery, a little math is in order. We will use a simple formula to determine charge rates - divide the "mAh" of the battery by 1,000 (let's say a 2200mAh battery), which comes to 2200 / 1,000 = 2.2. Now, multiply it against the "charge" rating of the battery, which in this case is 5C – 2.2 x 5 = 11. So, if we have a 2200mAh 5C battery (2200 divided by 1,000 = 2.2), we have 2.2 as our base number, which we then multiply against the charge rating of "5C," which gives us a number of 11 – (2.2 x 5 = 11). What this means is that at a 5C rating, a 2200mAh Pulse battery is capable of being charged at 11.0 amps.
