LiFePO4 Batteries

That's a vote of one... for using a fuse on the battery.

Bought the Tenergy because of recommendations of fellow glider pilot friends and good customer service. Actually, I was intending to pay a little more for the K2, but at Batteriesinaflash.com, the customer service guy told me that they weren't available from the company for up to 45days. Batteriesinaflash.com doesn't carry the Tenergy because "...the K2 is a better battery". The next day, I received a return call from the company rep, K2... and as it turned out could have picked one up from them or WingsAndWheels. K2 says that their BMS is better quality and same for the battery all the way through. Of course, it's a little more expensive. Based on WingsAndWheels and David Springford's business, it appears other have come to the same conclusion that the K2 is a better battery.

Let's hope infant mortality on my Tenergy BMS won't show up for awhile. The price on the Tenergy 12.8V 10ah with free charger was $160 minus $19 discount before taxes and shipping. So, it appears that they are discounting them a bit... probably because of more failures.
