Battery recommendations

[waterworld motorsports]

I just purchased a MHz 138 I?ve got two to 5680 motors an ztw 300 esc looking to go 8s or 12s looked at the true spec dv22.2 6500mah 120amps/75c with g10 plates not necessarily looking to race trying for a good speed are these any good for the price an will they last any info or recommendations appreciated thanks

It's serious power for a serious boat ,look at steffansliposhop.de or hobbyking graphene panther

No one can really help the OP without more information.

- what is the Kv of the motors?
- is it 8S or 12S? You can’t have both.
- what is ?a good speed??
- what kind of run time will you expect?
- why do you need armored packs?
- what is your battery budget?

The motors are 800kv a good speed close to 100 as far as run time 10-15 mins an for the armored part not sure what that is an for my budget don’t wanna spend max amp prices but something reasonable thanks

No one should ever spend Maxx Amp prices... the most over priced, over rated, poorly tested lipo batteries made.

[EddieM41]

Made that mistake once (Maxx Amps)....never again!!!

What batteries do you have good experience with

Graphene panthers.

I've moved to HRB.

Roaring Top, look at the record book. Not expensive and weight per ma is one thing I look for.

HRB - 100c Graphine

There are a couple good brands for boating needs.
If you are running 2P per motor the HobbyKing Graphenes are hard to beat for performance and value. The solder tabs are the weak point in these batteries so paralleling them reduces the current draw per pack. You can use two 3000mAh packs in parallel to get 6000mAh. Their chemistry is very stable and I have not seen much degradation over time.

If you are running 1P I would recommend the RoaringTop 80C cells or Dinogy Graphene 2.0 70C cells. Both these companies are run my model boaters and the cells have good construction and chemistry.
Since you are running a twin cat you cannot likely fit 2P of cells per motor are the higher cell counts so the RT's or Dinogy's would be my recommendation.
