Sweet dealReview by Steveomaxx
Running awesome in Xmaxx,got them on Easter day sale.20$ bucks off.wish I could have bought more.if you didn't get some of these you missed it. (Posted on 4/21/2017)
Absolutely amazing!Review by trout74
These batteries are fantastic. I bought them for my XMAXX and they are perfect. Fit perfect, hard case is very strong. I drove for an hour straight, and they still didn't hit LVC. I checked voltage after 1 hour and they were at 3.71 volts, so they still had more to go. Arrived perfectly matched, both packs. These are my 4th and 5th batteries from RCJuice, and they continue to impress. Thank you so much. (Posted on 9/8/2016)

Can you get these in with an EC5 connector? Also, will two of these fit inside of a Losi Super Baja Rey?
We can swap plugs on any battery free of charge, please see details here: https://www.rcjuice.com/swaps

We have looked for the full tray dimensions of your Losi and they do not list the height. These do fit length and width wise and we are about 99% sure they fit stacked in there but you'd need to measure to be 100% certain.

Does this pack fit the Losi 3XL-E? I havent purchased the truck yet just trying to line up solid battery packs.
Yes, these do fir the 3XL. BTW we can also swap connectors on any battery if you need these with EC5's, just include a note at checkout and if possible send us a reminder e-mail to support@rcjuice.com.

I have a skyrc e660 charger could you please tell me what the settings are for a 8000mah lipo 11.1v 100c - 200c battery
We are unfortunately not familiar with the specific chargers (most SlyRC chargers are unavailable to US dealers due to the contract SkyRC has with Hitec and the manufacture of their chargers). Regardless, for you battery it depends on what charge rate your packs are rated for and/or what you want to charge at, but most importantly in this case is the charger limitations. At a 1C charge rate, you'd be charging that pack at 8.0 amps, but the E660 tops out at 6.0 amps anyhow. You can charge your pack at 6.0amps not problem.

Will this fit in a 4x4 stampede
No, even with the expansion kit that will only fit a 42mm tall battery. Check these for 3S packs for the Stampede:

hi do these come with deans connectors and 10 gage wire?
Dean's is one of the options that is offered (select "Dean's" from the drop-down) and yes, they do come with 10AWG wire.

Just wondering if 2 of these would work well for arrma Kraton?
Unfortunately no, they are far too large to stack 2 in there. The most common packs for a Kraton 6S setup are our 5200mAh 45C soft packs, 2 of them fit nicely in the Kraton tray (we are currently out of stock of XT90 packs but if you order any other plug style and include a note at checkout we can swap in XT90's for you at no charge). https://www.rcjuice.com/lipo-batteries/3s-11-1v/hobbystar-5200mah-11-1v-3s-45c-lipo-battery.html

If you want a single hardcase 6S pack then this is a popular choice as well: https://www.rcjuice.com/lipo-batteries/6s-22-2v/hobbystar-4800mah-22-2v-6s-50c-compact-hardcase-lipo-battery.html

Fit this HobbyStar 8000mAh 11.1V, 3S 100C Hardcase LiPo Battery in the vxl rustler 2wd
Not in the stock configuration, you'd need the Traxxas 3725X expansion kit (measurements are not provided on their site so you'd need to measure and compare to this battery's dimensions). This pack is a 3S in a 2S sized case that drops right in: https://www.rcjuice.com/lipo-batteries/3s-11-1v/hobbystar-4200mah-11-1v-3s-40c-hardcase-lipo-battery-compact.html
