Electric 53" Catamaran build thread

you are only using 3400mah because it's 10s2p

But I charged each 5S pack individually and put in +/- 1710mah into each pack. Power supply blew up on me so now using laptop power adapter to charge each pack individually.

the packs were used as 10s so effectively 2 x 5s packs in series behaves as 1 pack.
total mah used is 10s 1710mah multiply by 2p, so 3420mah total used

at that kind of power level you are running, time to invest in a bench power supply of at least 20amps to support your multiple charging

meanwell comes to mind

OIC.

I do have a 10amp regulated supply but just kaput last week. Now its in a shop at SLT for repairs. In the mean time, laptop power adapter is temporary only.

Anyway will rest this boat till after CNY. Too big or a hassle to bring it to pond. Too big to fit in my boot and seats by my side when I drive.

If you don't want to buy a bench power supply, you can use a 40amp/hour 12v car lead acid coupled with a charger. Works as well just that it takes up space

and you need a bigger car

My 10A power supply is back at home with a $35 repair bill. My costly mistake to charge 10S at 1A on one charger and 4S at 3.7A on another charger.

I need a panel van, not a car!!! So that I can store my boats there permanently.

Had some company with me this morning at the pond.

Video my running today. Never able to full throttle it in tis pond. No camera man, just static video taking only.

Nice meeting you, Adrian. Good display of her power.
i believe in a windless and wave free day, she can hit more than 100kmh!!!
Just be careful of the surrounding. If boat flip as least you know which direction is safe. Have fun, Adrian

[Adrianli]

Nice meeting u too. I'll definately come back to BR to run this boat as it is now the only place where I can stretch her "legs". But will be running her in the early weekend mornings like I usually do. No wind and no wave.


Also PUB hotline number stored in my HP.

Wats the service charge? hahaha.....one time i walked to the other side to fetch my hurricane. Radio just went out sailing on her own. To and fro one hour walking and jogging with the tx in the morning. Jogger looking at me with strange eyes. They must be thinking 'hey, this guy with a new type of am/fm radio' for listening to music
