Built this over the winter with my 8 year old. He took every nut and bolt off the ski and did the fiberglass! So please give him a like and sub on youtube. ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Couple things I could use some help with. My Ant bms/battery only charges to 4.158 per cell. Any tips on getting it to charge up to the full 4.20v per cell? 20s2p SPIM08HP battery
I have read through the votol thread a few times now, but if anyone has any tips on how to get the absolute max power out of this thing that would be awesome. After the kids riding for around 15minutes and me trying for a few minutes she only used 2ah and the motor never got warm. So I am thinking she is no where near her potential.
Top speed of 25mph! Going to try with a direct coupler next. Not sure the sprocket has another run left in her.
Ski ready to ride weight is 226lbs. Battery weighs 35 pounds! Once I figure out if I want to stay with sprockets or swap to coupler I will shave some weight off or maybe go to aluminum. Also thinking I can cut out the hood liner for a few lbs.
Specs:
QS-120 motor 2000w / Maximum Torque: 20N.m to 49.6N.m.
Votol em-100 controller
Battery 20s2p 16ah SPIM08HP
ANT 300a bms
Ski 1986 300sx
Motor sprocket 14T Driveshaft sprocket 10T (Did this so I could adjust rpm/torque with sprockets)
Still trying to Figuring out the rpms Vs Torque for a jetski.. In the video I think the top speed was around 15mph.
