My 420 watt portable charger is functional.
Gets a little too hot for my liking at 300watts, even with a massive heatsink.
Its 7s2p prebuilt 104wh battery is not confidence inspiring.
I could in theory make a 7s2p 18650 with double that rating.
But capacity ratings are very misleading when cells are discharged above 0.2c.
Right now I'd choose EVE 35v's as they perform very well upto 10 amps, and are 2.95$ each.
They outperform the Panasonic/Sanyo 3500mah GA cell that is used in a lot of e bike packs, and cost half as much.
