SuPower Battery have sent over some details of the batteries they make:
Are you still using NIMH / NICD batteries for your arms?
Ni-MH, NI-CD battery have been widely used for many years, but some disadvantages appear, such as fewer life cycles, shorter run time, bad performance in cold temperature, higher self-discharge level, voltage drop at near-discharged levels, Heavy– making it harder to use and carry out for longer periods of time, Memory Effect or False Bottom Effect if constantly discharged half-way and then recharged.
With development of battery technology, competing battery material are being more and more used recently: Lithium ion, Li-polymer and Li-FePo4 Power batteries. Lithium and Ni-Mh batteries have their advantages and disadvantages, but which is a better fit for hobbies and your arms?
Comparing with NIMH / NICD battery, Lithium battery has the following advantages: small size, light weight, high voltage, Long cycle life, low self-discharge rate, no memory effect, no pollution, safety and good. Li-Polymer battery is also a kind of Lithium battery, as it is extremely light weight and with great power rate, more and more players prefer to use it. But it also has one disadvantage that its very easy to get flammable even explosion.
LiFePO4 was discovered by John Goodenough’s research group at the University of Texas in 1996, as a cathode material for rechargeable lithium batteries. Because of its low cost, non-toxicity, the high abundance of iron, its excellent thermal stability, safety characteristics, good electrochemical performance, and high specific capacity, it gained some market acceptance.
Li-FePO4 has the following features:
1, a high efficiency output.
2, good performance under high temperature.
3, steady discharging performance, the discharging process of voltage remain unchanged, the discharge voltage only goes down by approaching termination, the battery discharge characteristics are very good.
3, no explosion or burning even if the battery internal or external part being damaged or short-circuit.
4, excellent cycle life, discharge capacity remains more than 95% even after 500 cycles.
5, fast charge.
6, light weight comparing with NIMH, NICD battery.
7, low heat under high discharge rate.
7, low cost.
8, green material, environmental protection.SuPower Battery has been making effort to provide battery packs with better performance for players, the SuPower Li-ion, Li-FePO4 series Power battery packs obtain high reputation from worldwide airsoft gunners.The on going promotions will benefit both individual players and wholesalers this season.
