How to Change Over From NiMH to LiPo Batteries
LiPo batteries are environmentally friendly, unlike NiMH batteries. (two batteries image by KtD from

Nickel metal hydride (NiMH) batteries produce 1.2 volts, while lithium polymer (LiPo) batteries produce 3.6 volts. The obvious advantage if you change over from NIMH to LiPo batteries is you don't need so many LiPo batteries to power your device, as the voltage ratio is 3:1. Additionally LiPo batteries are more durable, lighter and produce higher milliamp hours (mAh). If you're using an external battery pack to power your device, changing over from NiMH to LiPo is easy, but it can't be done if you have an internal battery pack, as the batteries don't fit.

  1. 1

    Check the voltage requirement of the device you want to power when you change over from NiMH to LiPo batteries. It's important you can match the same voltage. For example: if you have three NiMH batteries you only need one LiPo; if you have six NiMH ,then you only need two. Don't exceed the voltage of the device you want to power, as it will be damaged.

  2. 2

    Purchase the number of LiPo batteries you need using the ratio 3 NiMH to 1 LiPo. It's best to buy a battery pack, as it includes the connections to power your device. Take your device to the store to ensure that you get compatible connections. You can get LiPo batteries from most electrical sockets, although they do cost more than NiMH batteries.

  3. 3

    Connect your LiPo battery pack to your device. You find your device operates as before, but should last longer and may even operate better.

Tips and warnings

  • An additional benefit of using LiPo batteries is they can be disposed of in regular trash, unlike NiMH batteries.
