I quickly pressed the > button on the E-meter...GEEEZ!...60 AMPS! Sorry Rich, but 60 amps sounds a bit wimpy after seeing my dump charger send a ballsy 279 amps into my Hawkers! As part of ther OEVA 'EV Awareness Day' excitement, on that morning my race car's dump charger parallel-series protection circuits were inadvertantly 'tested' when there was a short circuit/fire in the trunk of the car (thankfully, no plasma this time)! Since then, the protection circuits have been worked on and are still being modified, and an all new system was built which included beefier charge wires to pass more current. Though after the first 15 seconds or so the dump charger drops to something more like 140 amps, the last dump charge of the day (when the 17 host Optimas had been cycled a few times and were really rock'n) showed that massive 279 amps of initial current flow....now there's a 'Wow!' Dump charging used to take about 8 minutes, with an 80% charge in the first three minutes, but Sunday that time was closer to 5 minutes for the whole thing! Not to take away from Rich and Joe's wonderful chargers....it was my mighty PFC20 with the buck enhancer, that kept the dump charger's 17 Optimas fully charged, via the10kw generator that helped charge other EVer's throughout the day as well (thanks, Daniel Eyk for loaning it to me). My PFC20 has been tweaked a little by the MadMan and can push 30 amps into the Heavy Metal Garden Tractor! I used to use my 'Ugly Box' capacitor charger for this duty, but last Sunday it was left at home and the PFC20 took over...what a great charger! The day after the races, that same PFC20 was placed in Jon Sheer's Honda's back seat and it helped to get him home by working in conjunction with another Manzanita Micro charger to convert the tow-behind-generator's AC juice into battery charging DC. These powerful and flexible chargers are the best I've ever used...period! See Ya........John Wayland
