If you just type in your search engine - hybridautocenter.com - you will get to the main page.
Then click EV PARTS SHOP These batteries are from as Hybrid Auto Center. The cell specifications is: Cathode Material - LiMn2O2 with LiNi Anode Material - Graphite Rated Capacity 33.1 ah per cell It look like you knew what I type meant ampere hour. I am a old geezer which my fingers may type something else other than I was thinking. I started in the electrical with my father in 1944, so that will tell you how old I am.

Each module weighs just over 8 lbs. I assume that by a/h you mean amp-hours, or AH. (A/H would be amperes per hour, a meaningless unit.) If so, that would be 554Wh per module. Eight lbs is 3.6kg, for a specific energy of 154 wh/kg.

But the specific energy above (154 wh/kg) is more than double that which is normally available from NiMH (70 wh/kg). Also, unless I missed something, NiMH cells are around 1.2 volts nominal, and most lithium chemistries are around 3.2 to 3.5 volts per cell. The voltage you state above doesn't match any of those. Perhaps you could explain more clearly what batteries plan to use. Thanks, looking forward to hearing more.
