First glance..these are a good buy... inexpensive and work well in most applications... a word to the wise.... do not charge too fast, or quick charge... battery life suffers.. I have several of these in different applications, and so far I have only lost one to swelling in about a year...I haven't had very many expensive batteries for any serious comparison. These are a great beginner's battery and for those who just mess around, yet I suggest a higher discharge rate for serious racing.
