USA & SINGAPORE JOINT VENTURE
With the GOPACK series we use special hardened carbon active plated coated with the only spray coating machine in China.
Also the copper current collectors are specially treated so that the carbon adheres better thus lowering IR.
Lower IR = Longer Life packs
In a nut shell the environmental control during the assembly process and the raw materials are the key.
With spreay coating process and hard carbon material we think we out perform our competitors.
Also since we make our own cells & packs you get the best price.
Unlike most other brands in the market we make our own cells & packs. Thus you are getting them factory direct.
Yes you can....IF the cell has been designed by the factory to do so and if your charger is safe enough to handle the safety issues like our PowerLab and CellPro chargers.
Fast charging causes heat and heat can either cause fires or at a minimum decrease the cycle performance of your pack. If you don't need to fast charge over a 1C rate then don't. It will save you money too.
Now some RC cells have been designed for fast charging but....with limitations.
1. Typically the stated fast charge rate is at a higher temperature of the battery say ~35 degC. Above or below that and the manageable C rate is lower.
2. Also the temperature is of the pack at steady state, not the ambient temperature.
eg: having a warm pack that is stable at 35 degC in a cold room you can fast charge having a cold pack that you have taken into a warmer environment you cannot fast charge until the pack has reached the same warm temperature. This will usually take a few hours.
Be careful with the fast charging capabilities of lithium, it does come with limitations.
No. There is no need to run-in or pre-cycle lithium polymer batteries before playing.
In the formation process of lithium batteries a SEI layer is formed on the exteneral later of the anode plate. This is very common and the layer is removed by the factory formation process during one of the quality control processes, thus pre-cycling of lithium polymer batteries is not required.
On the other hand lithium phosphate batteries do get stronger in power and capacity within the first few cycles due to the electrolyte seeping through the outer coating of nano phosphate material. Once the electrolyte is fully soaked into the anode material electron transfer is faster and easier thus a better performing battery.
Firstly, the lithium Ion polymer battery has no risk of explosion due to the characteristic of its own package, since the battery explosion occurs only in the abuse or battery internal short circuit.
The abuse mainly refers to overcharge. We have evaluated a 20AH lithium battery; it will not explode even it is overcharged to 10V.
Because the outer layer of plastic film of battery can withstand the pressure about 2Mpa. There is not large enough pressure to incur an explosion. Generally, the explosions occur in steel and aluminium shell batteries, because such batteries may produce gasses which are likely to form a high-pressure, high-temperature.
We conducted overcharge test up to 5V for 2.5hours for RC cell and there was no explosion.
The explosion occurs when the positive active material and electrolyte cannot stand the high voltage such as over 5V.
To stay safe we suggest 4.3V (Blend435) and 4.20V per cell (Bloend420) per cell should be safe for any well manufactured cell
Now here is a tip or two.
1. if your charger can control the voltage per cell down to 4.1V then you will see an extended life cycle of your pack. So its not full you say. Correct. But you never fully empty your packs anyway.
2. if your charger can control the voltage abover 4.2. Say 4.22 - 4.3, it is still safe especially if you have active charge control and you'll get extra capacity out of your pack on race day. Up to 25percent more...but, life cycle will be sacrificed but that is ok for those special race day competitions and the little extra boost you need on the day.
You may be wonder what the benefits of our "HV" series of lipos are for RC Hobby?
Much like iPhone and Galaxy who are already using HV lithium one gains the following:
1. With higher full charge voltage you get more power
2. With higher capacity you get longer play time and more power at the end of your run
3. With Lower IR you get longer pack life
Just like normal lithium packs you should use a LiPO charger with good balancing function. Best charging for longest life is at 1C rate
Raw material and process.
We use pre processed matt finished copper plates thus the active material sticks better to the metal current collectors.
HardCarbon GO also allows better transition of lithiumIONs thus the lowest IR in the industry.
