Modular Parralel Pack Design Valid?

Toying with the idea of making a bunch of individually shrink wrapped 8P packs with 2 x 2 leads of 10Awg terminated with 45 amp Anderson plug leads and JTX balance leads coming off each pack. The 8P packs would have a pair of positive and negative 10Awg leads at opposite ends of the flat 8P pack ter...

Re: Opinions - Lyen 18 FET configuration

I use regen but only with the temporary push button under my throttle for a "downshift" feel. I don't always like for the regen to always kick in so hard from the brake handles in some situations. I find the EBS level 1 @ 75v is more than enough for me to almost exclusively serve as my brake and wou...

Opinions - Lyen 18 FET configuration

Hello, I'm looking for your opinions on my current config / possible maximums for my rig. I am running a ventilated HS3540 with 18 FET Lyen Low Rds Mosfets. So far I am loving this combo! Here is a screenshot of my current config file, plz disregard the LVC : http://i1338.photobucket.com/albums/o689...

Re: Off Grid 12v - Bulk Charging 15S5P

There are a few issues with using the charge controller as a charger directly to the Lipo. I would have to manually disconect and re-conect a 2ga cable... not to mention that my charge controller coulden't handle ~60v. I think I'll just pick up a second Hyperion and give that a go. It will definatel...

Re: Off Grid 12v - Bulk Charging 15S5P

Thanks for your reply Alistor, I guess bulk charging using two meanwells might still be the cheapest / most adaptable / easiest option, even if the origin is a 12v power source. That would allow me to bulk charge anywhere also. There is just something that seems a bit rough about going from 12v DC, ...

Off Grid 12v - Bulk Charging 15S5P

Hello, Just finished up the carbon/kevlar enclosure mounted permanently straight to the frame of my Klein Mantra for my new LiPo pack and man... It's a little on the tight side of my "precise" measurements, I really don't want to ever have to take the batts outta there and risk anything. :oops: Espe...
