I picked up some IMR 26650's and a 4 Seven's charger a few months ago with intentions of building an SST-90 2D Mag, but that project has sort of stalled out.
I have only one King Kong 26650 & 8x A123 LFP for my motorcycle in 4S2P configuration.
Charge King Kong with Xtar WP2 II
Charge A123 LFP with iMax B6AC Pro hobby charger.
