During the summer my garden tractor battery went bad and Alien Motion had their AN22 battery on sale for $209.00, so I purchased one, with the intent of using it in the garden tractor until the end of the season, then putting it in the Fiero. It had plenty of power and started the 14 horse engine right up. I mowed for a couple of weeks, but the third week, when the key was turned, nothing happened. Upon inspection of the battery, the case was swollen and there were some dark discoloration where it had got hot. I sent the battery back to Alien Motion and they ask me to check the voltage output on the Garden Tractor. The next time I mowed, I took voltage reading when starting of 15 volts and after I was finished, it was still reading 15 volts, so the voltage regulator was not working. After sending Alien Motion the voltage readings and telling them that my voltage regulator was bad, they actually owed me nothing under their warranty terms but instead offered to send me a new battery for $100.00.  I felt they displayed that they would stand behind their product, even when it went bad because of unwarranted causes and would recommend them to anyone interested in a good LiFePo4 12 volt battery for your build. They now have a protection board available for $34.00 extra that will keep the battery from overcharging or over discharging.
