2 year plus update Link
I heard really good things about this pack and with them being the cheapest hardcase packs ($15.50) on hobby kings site I just had to give them a try and see what they were made of .
Well I started by checking the voltages when I got these in . One pack was at a little down with cell 1 at 3.84 and cell 2 at 3.85 . The second pack which by the warranty number was a bit newer was at 3.86 on both cells so in my opinion things looked pretty good from the start . I then solder on a couple of dean's style T-connectors and proceeded to charge the packs up . After handling the wiring harness a bit I decided I didn't want to use the stock harness for running in my car or for fast charging and made 2 more harnesses minus the balance plug as it could be damaged . After the packs got done Balance charging I decided to take them for a spin and yes virginia these packs do have some punch dare I say more than the Turnigy 30C 4000mah packs I tried hmm further testing is needed because despite feeling Zippy these packs did warm up a hair bit but that may be due to this being there first outing . After I get a few more cycles on these and the Turnigys I will be updating these post .
This pack has a Relative Amp 25C x 4A = 100rA
$15.50 / 100rA = 0.155cE the lower the number the Cost Effective
