User Manual

14) Will these batteries wear out my motors more quickly with the power they offer?
These batteries will not wear out your motor any faster than any other RC battery.
15) How safe are these batteries?
These batteries are very safe and abuse tolerant. They have many safety advantages over Lithium Polymer
batteries.
They are not prone to thermal runaway, which is the leading cause of fire in Li-Po battery technology.
They will tolerate some amount of over-voltage before failing. Our batteries should be charged to 3.6V / cell.
They will tolerate up to 4.2V / cell with little damage. Charging to 4.2V / cell repeatedly will have negative
effects on your pack. Repeated abuse will yield much lower cycle life, and can result in pack failure.
These batteries also tolerate over-discharge. We recommend a cutoff voltage of 2.0V / cell but these cells will
charge up perfectly fine even as low as 1.0V / cell. As with over-charging, it is not recommended to
repeatedly discharge below 2.0V / cell as it will affect the cycle life and could cause pack failure.
These cells are manufactured with a Laser welded aluminum canister. This helps to prevent damage from
physical abuse such as dropping or crashing. Even with this protective canister we highly recommend that you
take extra care when handling and using your battery.
16) How do I store these batteries?
These batteries can be stored at any state of charge for short periods of time (3-5 days). These batteries can
also be stored safely for long periods of time. At 50%-100% state of charge these batteries can be stored for 6
months. They can be stored for up to 12 months if they are charged to 100% state of charge beforehand.
17) What kind of life cycle can I expect from these batteries?
Because of our Nano Phosphate technology we are capable of delivering many more cycles than a Nickel
Metal battery or even a Lithium Polymer battery. Your pack could see up to 1000 cycles before reaching 75%
capacity. In an average RC application you would expect to see over 200 cycles before noticing any change in
the battery pack.
18) Can I charge my Li-Po and other packs on the Sonic Charge charger?
The Sonic Charge system was specifically designed to charge our A123 Racing packs. It is NOT for use with
any other battery pack, including NiCad, Nickel Metal, Lithium Polymer, or other Lithium Ion packs.
19) What is the charging voltage?
The required charge voltage for an A123 Racing cell is 3.6V. Therefore, if you have a pack that has 2 cells in
series, it should be charged to 7.2V, and a 3-cell pack charged to 10.8V. A pack can be charged at 5C.
5C x (Capacity/1000) = charge amperage. For example our 6.6V 2300mAh pack 5C x (2300/1000) = 11.5A.
20) What RC applications can I use the batteries in?
We currently offer 3 different pack configurations, a 6.6V 2300mAh pack, a 6.6V 4600mAh pack, and a 9.9V
2300mAh pack. These can be used in any RC application that the user desires whether it be a brushless or
brushed motor. It is also possible for a user to wire 2 packs together in series and/or in parallel. For example,
