NiMH NiMH stands for Nickel-metal hydride. NiMH batteries have larger capacity capabilities than NiCd batteries but they tend to self discharge quicker (while not in use). While a NiCd would be preferred in a remote, the NiMH battery’s high capacity makes it a great choice for R/C vehicles. Like the NiCd battery pack, the NiMH packs are usually 6-7 cells with a nominal voltage of 1.2v per cell. NiMH batteries are easy to use and maintain. Most chargers today are rated for NiMH batteries making them simple to charge. They do not form a memory, like NiCd, and do not need a voltage cutoff, like LiPo batteries. NiMH batteries have high discharge ratings, but it’s easy to tell when they are getting low because the voltage will gradually drop off, slowing the vehicle. The NiMH battery is the most widely used battery pack in RTR R/C vehicles today because of their reliable performance and ease of use.


LiPo LiPo stands for Lithium-ion polymer. LiPo batteries are a completely different chemistry than both NiCd and NiMH batteries. LiPo batteries don’t require pressure, as do NiCd and NiMH, which allows them to be constructed without the same metal casings the other cells use. A typical LiPo battery pack consists of 2-4 cells with a nominal voltage of 3.7v per cell. LiPo batteries are superior in performance but require more care when being used. LiPo batteries must be charged with a LiPo specific charger and must be used with a voltage cut off device. If a LiPo battery is completely discharged it becomes unstable and will not properly take a charge. Many of the brushless vehicles come with a LiPo ready ESC which has a built in voltage cutoff for that reason. LiPo batteries have a low initial shelf discharge rate but will drain themselves beyond the minimum safe voltage level if not charged some before storing. Most LiPo rated chargers have a storage setting for this very reason. LiPo batteries have very high capacity ratings and an even discharge rate throughout the entire “safe” discharge cycle. This means full power till the end of each run. The major disadvantages of LiPo batteries is their instability. Over charging the pack makes it unstable and can cause combustion and fire. LiPos must be charged with a LiPo specific balance charger and should be placed inside a LiPo charging bag, just in case an accident occurs. LiPos have quickly grown in popularity because of their high capacity and strong performance. If properly taken care of, LiPo batteries can be used for many years with little loss in performance, making them perfect for Brushless R/C vehicles.

Charging a LiPo Battery

get a LIPO CHARGER. You cannot charge lipos with ordinary chargers for NI-CD, etc.

Do not charge near flammables/explosive substances

Triple check your setting on your charger before you charge

Don’t charge it over night, always keep an eye on your battery.
