WhataNut FMA PowerLab8 1000W charger

[MindThoughts]

I'm very interested in your test results for any and all LiPo and other chemistry batteries tested. Please do post your findings.

PS. Is it also possible to use two PowerLab 8 chargers wired in (series or parallel) to charge at- for example- up to 80Amps? For example- some of the High Mah(capacity) LiFePO4 chemistry batteries say they can be charged at up to a 15c charge rate- which for this model and capacity(6750Mah 3cell LiFePO4) = a 100 Amp Balanced Charge Rate. In which case we would need three PowerLab 8 Chargers Wired In (Series or Parallel?). Is it possible to wire the 40amp PowerLab 8 balance chargers in series or parallel- in order to achieve the 100amp balanced charge rate? I can see that though a 40amp balance charger is awesome and great- I agree with your son- we need more power from one charger :) a 100amp balance charger would be quite nice- and I'm sure FMA Direct is already beta testing them as we speak. Howard in tech support at FMA Direct- where I purchase my two PowerLab 8 Chargers- said they were Beta Testing the PowerLab 8 chargers for three years with zero major problems.

Here is the direct link to the LiFePO4 Chemistry Battery which can be charged at 100 Amps and comes with a 5 year 1000 one thousand cycle warranty. This link is to the 3cell variety. I may try the same capacity in the 2cell variety to reduce weight, or even try the 4cell 2250mah LiFePO4- considering that I'm running a 3600kv motor and my Mains/club races are only 7 minutes. I'm running an Ultra-Light Full Carbon Fiber(By Matrix Concepts Inc) Hyper 9E with a 3600kv 1/10th scale motor which is very fast on one- 2cell LiPo(on a medium size indoor- high bite- clay track). I realize the LiFePO4 Chemistry Battery is a little lower voltage compared to the LiPo chemistry battery- but I should be able to gear up(add one or two or maybe three pinion gear teeth) in order to compensate for the slightly lower rpm produced from the apx 1volt difference between batteries :)

I figured that with a parallel balancing connector I can use dual Powerlab 8 do discharge at 80A, or use triple Powerlab 8 for 120A discharge rate. That should put a battery to test of true advertised C rating.
