So i have everything to build my board except the battery. i have TB’s 6374 190kv motor and TB vesc, i know i want a 12s4p but im not sure where to buy from… i was thinking about just going for TB’s 12s4p but didnt want to just jump at it without others opinions. i have around $520 max to spend on a battery so some advice would be greatly appreciated.

I’m in the process of getting my parts together as well!. I’m currently in contact with @TinnieSinker on his pre-made packs. easy to chat with and accommodating, W’ere working with getting a Bestech BMS to go with a 10s6p 30q at the moment and you can also request the pack in a certain config(i.e. double layer triangle stacked) so you can hit him up!

The TB 12s4p is a good pack. Its made with Samsung 30q’s and comes with a decent enclosure.

i hear it has 30a continuous, do you think it’ll be able to let me cruise at 20-25mph and have a 20(or more) mile range? the enclosure is also a huge plus considering i dont have the means to make my own very easily.
its 60a continuous via the BMS, the new ones are 80a. Depending on gearing & wheels you can easily reach 25mph and 20 miles of range.

I’m not sure that exact price but @barajabali makes great batteries. Nothing but good things to say about the one he built for me that’s lasted a loooong time. Think he’s about in your price range too. http://chibatterysystems.com

Would’ve wanted to grab a pack from him as well but his site says do not order if not from America 
Ah. Gotcha. You should maybe put that in your first post so that everyone knows where you’re trying to get one from.
It looks like a 12s4p with 30q’s from him is $615… so a little out of my range, but still may consider it seeing as how everyone seems to love the quality of them.

I think it may be worth it given that its got a bms already. Im expecting something along that range for my 10s5p 30q + bms as well. Though I believe @barajabali has been doing it for longer so that’s worth noting

If I have a mboards dual esc, could I have a 10s 4p battery made from Samsung 25r cells? Or would that much current blow my esc?
Is building your own pack out of the question? If $520 is your limit you could easily build your own pack for less. I bought my battery spot welder for $150 on amazon and I got 60 Samsung 30q from nkon for $200 shipped. Got my 12s bms from bkb for $50(dont remember shipping cost). My welder came with a ton of nickel strips already so didnt need to buy that. If you are doing a 12s4p you could build it for less the $400 Including miscellaneous things like shrink wrap and xt connector. Then you now have a welder for future batteries. That’s what I did anyway.
@pjotr47 makes excellent packs if you are in Europe.
12s4p, samsung 30Q, fused, charge only bms, charging plug: 420euros shipped.
The TB battery is good too if you can deal with its bulkiness (double stacked).
