    Talking best lipo's for mamba monster 2200kv combo set up

    Hi,

    I'm currently converting my Revo 3.3 to brushless and i am totally new to the electric world so i would appreciate a little bit of advice from you bright sparks if you don't mind please...

    Basically, i'm going for the Mamba Monster 2200kv motor and ESC combo and i was wondering which lipo's would be best for longest drive time, longest battery lifespan and general value for money?

    The Castle Creations website recommend a 4s lipo for the MMM, if that is right, what mAh lipo should i go for?

    Thanks in advance guys!!!!

    Are you converting to a e-revo chassis? I would go for a max amps. They also make a Xl series line. Their biggest lipo is a 13500 miliamp 2s lipo. Two of these may work good. do you have a place for two batteries are are you going to just Velcro them down.

    No i'm keeping the 3.3 chassis. Wow, i didn't realise they do 2s lipo's with that much mAh! I've got one battery tray as i'm using the tekno conversion kit so that set up may not be viable. Do you know any decent 4s lipo's with a similar mAh? Am i right in saying the higher the mAh, the longer the battery will last in run time?

    Correct higher the mAh the longer the run time. Yes you need a single 4,5,6 s battery. Pass on the Max Amp batteries, not to start a battery war, but they are a bit to many $$$ for what you get. Same or better bateries for less are out there..

    edit that one online dealer has a 4s 6000 mAh 25c will work just fine... about 35~45 min..

    Thanks 87 GN,

    What type of charger would i need for a 4s 6000 mAh 25c lipo? Sorry for the noob question but i'm totally new to elec... I believe i shouldn't discharge like nicad's...? So i would just need a charger/ balancer then?

    I use a gens ace 5300mah 30C 2s ( two of them for 4s total ) and i recently converted my e-revo also, I have ran it for 30 minutesish each run and never run out of power! i get home and it is around 3.7V per cell, and the entire charge goes to 4.2V per cell and i have the cut off at 3.5V which i have yet to hit because I end up losing body clips or some stupid reason like it starts raining... ( *** )

    just i just made a video of me using these packs! check out the videos at the top of this forum catagory!

    the batteries costed me in total $66 for both

    I use the Thunder AC680 charger, runs at $55 and charges up to 6 amps which is really more than you will need for the e-revo! i charge mine at 5.3A and they charge in around 40 minutes, would usually be an hour if you ran them down!

    Ok cool,

    So by running 2 5300 mAh 30c 2s's together, it is like running a single 10600 mAh 4s? Or am i missing something?

    You will be wiring them in series to get the 4s, so it will be a 4s 5300mah 30C total

    This is a good start..
    Just don't buy no name Ebay batts...

    MY BATTS:
    2S 9000 x 28C = 252,000 divide 1000 = 252 amps
    2S 8000 x 28C = 224,000 divide 1000 = 224 amps
    3S 5200 x 40C = 208,000 divide 1000 = 208 amps
    2S 4700 x 25C = 117,500 divide 1000 = 117.5 amps
    I run in my Summit.. ^ Requires proper gearing^


    ( mah x c rating / 1000 = amps),

    The
    more amps the better / minimun of 120 amps.

    The ESC will only draw the amount of amps it needs.

    Higher the mAh the longer the runtime.
    For brushless systems 8000 mAh about 45 min & a 5000 mAh about 30 min.
    Times are longer for brushed systems.


    Batts in series double the voltage:
    2x 2s 20c 5000mah = 4s 20c 5000mah

    Batts in parallel double the mah capacity:
    2x 2s 20c 5000mah = 2s 20c 10,000mah.

    A temp gun is kind of a must have.....

    Hot motor + cool esc = under geared.
    Cool motor + hot esc = over geared
    Everything warm just right..

    Motor ~ 180/190*F maximum, ideally 140/160*F, temps can be 10* higher inside the motor
    ESC ~ pretty much same temps / Fan comes on @ 150*F
    Lipo's ~ 140*F max, ideally 100/120*F

    Besure to check sizing before you buy any batteries...

    In time some batteries will become discontinued...


    No particular order as to good, better, or best....

    2S

    With larger Lipo battery wires, you might need to - enlarge the exit hole on battery doors....
    or run wires out the vents..

    Anytime!
    That quote was thanks to 87 GN
    I also converted my 3.3 to an e-revo, it is a great decision! I love mine

    pm coming......

    all good info..^ you can build a light bulb discharger, or get a charger with a discharge feature. Why, well if you charge up, it rains or you can't run for a few days you need to get the batt(s) back to storage volts 3.85 ish...

    another choice for a charger copy paste

    Dynamite Passport Ultra AC/DC Charge/Cycler DYN4064
    not the biggest charge but easy to use. I had two then moved up. Buy more charger then you think you will need. Saves money in the long run.
    Integrated 1-6S Li-Po balancer
    8-amp charge rate provides quick charge times
    5-amp discharge rate
    AC/DC input provides flexible charging capabilities
    Blue backlit screen for easy viewing
    Charges 1-6S Li-Po/Li-Ion /Li-Fe, 1-14 cell Ni-Cd/Ni-MH, 2/6/12V Pb batteries
    Jog dial navigation provides easy navigation of menu
    Removable power cords allow you to only utilize the power cord you need
    JST-XH balance connector type works with many of today's popular Li-Po batteries (THP and Losi balance adapters available separately)
    Included adapters feature charge outputs for Deans Ultra plugs, Tamiya plugs and Tamiya to receiver and BEC-style adapters (Deans and Tamiya plugs feature banana output terminals)
    12-bit CPU controller provides precise operation
    Last setting parameter memory
    Reverse and short circuit protection
    100W power supply supports extremely powerful charge rates and easily outperforms competing chargers rated at 50 watts or lower
    Includes magnetic battery temperature probe

    Specs
    Input: 100-240V AC OR 12V DC
    # Cells: 1-6 cell LiPo/LiIon/LiFe, 1-14 cell NiCd/NiMH, 2/6/12V Pb betteries
    Peak: Yes
    Current Discharge: 0.1 to 5.0A
    Charge Rate: 0.1 to 8.0A
    Trickle Charge Rate: 50-200mA or Off
    Output Connector: Banana Plug
    Battery Type: LiPo/LiIon/LiFe/NiCd/NiMH/Pb
    LCD: Blue Backlit 16 Character Display
    Discharge: Yes, Cutoff Adjustable
    Overload Protection: Reverse and short circuit

    edit you prob don't need it but maybe some info to help
