Hopefully the price will come down a bit - that's why INWO's 11Ah @$9 LTO deal was too cheap not to give it a try.
I have spoken with INWO before and he also messaged me about them, it is a good deal. It would result in a 22AH instead of 20AH for the voltage I need, the extra 2AH adds 5 more pounds though. Next month when I have time to start the build I will probably get everything from him. But if those 20AH threaded batteries were a much better deal I probably would go that route to save the 5 extra pounds and ease of assembly. But for my first battery build this sounds like the best deal incase I screw things up.
Thanks for the ideas on cheaper chargers. The Chargery system is a complete system and will charge at 1500w which I hope translates in to a 45-60 minute dead to full charge. Would love, if possible while touring, to be able to tap in to all the EV charging stations. 240V 16AH that would be a 20 minute charge I'm guessing. I am sure that the batteries can handle that high charge rate but finding a charger that can handle that amount of power that is light would be difficult.
One my cross country bike trip one of my Li-Ion batteries BMS shut the battery down at 42.5v as I crossed the Texas state line. By the time I hit Florida at the end of my trip the BMS was shutting off the battery at 49v. Because of those problems I want a BMS with LCD set up so I can see what is happening with the battery and balancing. Currently if there is a problem I have no clue until the battery is showing signs of failure. I spent $1K on that 52V 15AH and got about 250-300 charges on it. That is a huge waste of money which I hope LTO's will solve.
Hope that snow melts soon and you can get some data to report!
