Buying Guide – What to look out for

Here are a couple of essential things to consider before you pick any 2S LiPo battery:

1. Capacity: This refers to the energy a battery pack can hold. Think of it as the fuel tank of a car when buying a 2S battery. A large capacity battery provides more operating time. However, it also adds more weight to the device.
2. Hard case vs. soft case: Hard case 2S batteries protect the cells and board from impacts. Hence, if you have a ground device, then you might want to get this type. However, a soft case battery might be a better fit, since there are little to no impacts when flying an RC toy.
3. Weight: A heavy battery adds to the weight of the entire electronic device, making it difficult to move. This becomes an essential factor if the device cannot function normally due to its weight. The tradeoff you'd have to make is between a lighter or a more powerful battery.
4. Discharge Rate: This refers to how fast a 2s battery can release currents to the motor of an electronic device. The discharge is rated in C, and a rule of thumb is to go for a large C rating available.
5. Charging time: Consider this factor if you don't want to wait for hours for your battery to charge.

In conclusion

As 2S LiPo batteries are becoming more popular, the need to find a top unit has increased. But, you don't need to scramble through thousands of products now that we’ve done the dirty work for you. Just use our list of the best 2S LiPo batteries to decide which is best for your electronic device.
