In February I bought 120 Thunder Sky LFP40AHA 40Ah Lithium Iron Phosphate cells. I got a very good price by standing on the coattails of another Auckland EV builder who was piggybacking on a much larger order arranged by Blade Electric Vehicles in Australia. Today I received word that they've arrived in the country, they have to clear customs and then I'll be heading over to Steve's to collect them.
Some people have had very bad experiences with Thunder Sky batteries and I'm well aware that this might be money down the drain. If they last 2 or 3 years I'll be disappointed but I won't be crying myself to sleep either.
I'll be doing capacity and load tests on each cell just as soon as I build a suitable tester.
