Vapcell K54: They handle up to 20 A, but capacity was below spec and both capacity and current delivery were worse than the G53.

Vapcell Boston Power Swing 5300: The unusual cells work but showed large variation; the author considers them overpriced and recommends buying only at a substantial discount.
