Any opinions on this kit from Maytech and what battery I should pair this with?

Alright, so Im having a battery made for this setup. Figured I’d go for 12s4p. What do I need for constant output and burst AMP ideally?

12s4p should give decent runtime as an assist
samsung 50S were the best option for me when i looked into it a few months ago.
in 4p, you shouldnt need the max 30A discharge of molicell P42A or 45B so can go for slightly longer lasting Samsung 50S 5000mah cells that can do 20A per cell.

Not sure if I’m messing up but to kick of this I ordered my son a skateboard for $270 that comes with a 12s4p battery. OR you can buy the battery only for $285.
battery will provide continues 60AMP and 120AMP burst. It seemed like I really could not go wrong with this unless itsa scam and the item never shows up.
Links to board and battery below. I’ll report back how this works but im prob atleast a month out from getting all parts together.

Oh yeah believe pack is made with Samsung 25S 18650 2500mAh 25A cells.

I had a horrible experience with Maytech. Much better experience with Flipsky

Only reason I ended up with Maytech is because Flipsky refused to help me. Same person over and over that doesn’t understand English at all. I gave up after two weeks and 40 messages back and forth. Can’t imagine having to deal with them if anything goes wrong.
Hopefully Maytech works out. I had no option really.

I am surprised this thing didn’t blew up with such a long cable from battery to esc.

Noted, haven’t used it yet but sounds like you recommend me shortening those wire by allot.

I’m not an expert and lack extensive experience, so I rely on the collective knowledge of others—most of whom place the ESC close to the battery.
Practical considerations are the most important, but I can share the theoretical reasoning.
(I actually hope I’m wrong, and if proven otherwise, I’ll be the first to reconsider placing the ESC farther from the battery.)
Wires have inductance, and longer wires have even more. The ESC draws high current in pulses, which consist of multiple frequencies. When combined with wire inductance, this can lead to oscillations or excessive voltage spikes. Large input capacitors are added to the ESC to counteract these effects and stabilize the voltage, but they have a design limit. While I don’t know the exact limit, the fact that ESCs are typically placed just a few centimeters from the battery suggests it isn’t much farther than that.
On the other hand, the motor itself already has significant inductance, so adding more through wiring doesn’t make much of a difference. The electrical system behaves as follows:
- The **battery** is a passive energy reservoir.
- The **ESC** is an active consumer and regulator of this energy.
- The **motor** is a passive consumer driven by the ESC.
Since the ESC ACTIVELY DRIVES the motor, it can manage longer motor wires. However, the battery is passive and doesn’t regulate power in the same way, making shorter wiring to the ESC preferable.
Reasons one might place the ESC closer to the motor instead:
1. **Higher motor current** – The motor usually draws more current than the battery supplies, so a shorter cable could improve efficiency (though I haven’t tested this myself).
2. **Cooling considerations** – The ESC may benefit from better cooling when positioned closer to the motor.

I used a 1,3m long cable for an electric outboard last season with a 75350 esc and 9kw 70165 motor. No issues so far. Your cables need to be big enough and the esc needs watercooling in my case. Shorter is a little more efficient but sometimes not possible and you have to deal with that always.

Check out the length of the cable on this setup with this exact kit.

I’ve built my assist with this setup and it’s great. Mine is built into my own designed board with a solid IP68 rated box esc is out back everything is accessible from under board. Only two test runs yet needed extended antenna outside on front of board and now I’ve also changed pitch angle of motor so it drives board forward and maybe down
to see if I can get my feet to stand back further where I usually stand when winging

IM finally getting around to this again and I’m stuck. The plan is the encapsulate the battery inside the board (foam). Will I be dealing with battery overheating issues if simply used for foil assist? The BMS should manage temperature for safety correct and cooling will take a long time due to no ventilation I imagine?
Anybody out there done this before that can report how troublesome this build is or by a stretch ppl having no issues with this?

I have 10guage wires from motor to esc and 8 gauge from esc to battery. Battery is in this box totally sealed and nothing gets hot battery is bairly warm after full efoil run.

I have the same 10awg to esc and 8awg to battery. I’m worried in a box it atleast gets fresh air and water splashed on it. sealed in foam the heat will have no escape. its just so easy to just put it in the foam so really trying to get away with that unless anybody confirms its a bad idea. :).

What size battery and how long run time you thinking?
I’m running a 12s3pack 50p 21700 molicel 20ah I’m getting 20 to 30 full efoil. Even in foam I can’t see them getting too hot. But your right my box is thick but does get wet being fully submerged when board in water so yes it will stay cooler.
