Those are XT60s and the parallel lead is stock from HobbyKing and 16 AWG. The serial ones are 12 AWG. There is less current over the parallel connections than over the serial ones if I have been following correctly? So long since I did High School Physics I'm afraid, lucky me there is always...

You can use a parallel balance lead and use only one LiPo alarm plugged into the end. I would suggest one LiPo alarm for every two packs.

Two 4S batteries in parallel with LiPo alarms:

If they are in an adequate enclosure, sanely wired and correctly charged/discharged - yes as safe. I have seen a leaking Lead Acid eat through its support and fall to the ground (Italian car...) I have seen one boil on charge and spit acid all over an engine bay... Nowadays we have gel Lead Acid...

In France there is one speed limit to rule over them all... The speed limit covers anything using the road. A hand held radar might detect a speeding cyclist I am not so sure about the fixed ones.

I hope D8ve isn't reading you! Even slightly older riders can also get to incredible speeds from what he reports. Remove (or greatly diminish) air resistance in the cycling equation and moderate fitness is enough to move briskly. A motor removes the pain from launching to 25 km/h and climbing...

There are howtos on Endless Sphere IIRC, they have an electric boat section :)

The ammo box stops projected flames from melting your plastic boat. LiPo doesn't explode it projects smoke/flames, watch those axe man/plane crash/car crash youtube videos again. Isn't there one that gets shot with a .38??? :rolleyes: Yes it is a violent projection of energy but doesn't get...

The hebie is on my shopping list for the same reasons.

Human error is your worst enemy. A charging error is your highest risk. If you are worried you can put them in an army ammunition box. An aquarium thermometer has been mentioned on ES to keep an eye on temperature. Thing is I don't check my LiPo's temperature when I run for long periods at 15...

For the moment it doesn't have to win anything. You do realise that the EU can modify its China anti-dumping tarifs at any time and import stuff direct from China without going through the UK?

Not only the welders look great but the non weld packs from the Lithuanian guy look good too. I love his little stab at Vruzend with the log and the hammer :) Interesting times for the DIY e-bike builder with so many good battery building choices they are making it tough to decide!

Oh look! https://hobbyking.com/en_us/multistar-high-capacity-4s-16000mah-multi-rotor-lipo-pack.html?___store=en_us 3 x 16 Ah pack = 48 Ah nominative (about 40 Ah on the water) for £180 and it only weighs 3.87 kg - 587 Wh at 80% of nominal capacity...

Don't worry as of 2019 I am going to stop buying UK produce so you can eat my share!

200 billion pounds UK consumer debt. Sounds like a lot... Since the beginning of the year private French saving has topped 10 billion euros, that is money saved since the beginning of this year. That is a huge problem for the French economy, that money would be better used elsewhere. Seems we...

Always have!

Let's see: Tyrell's crisps - can live without, great farm made crisps just down the road. Wheetabix - can live without, perhaps... Marmelade - just found a new source in the Pyreneen foothills, yum! Cheddar - lots of great cheeses around here Do you make anything else I buy regularly?

@Nealh you are correct. It remains a 250W motor because that is what is engraved on the case. It will have a bit more oompf, 648 W peak, 756 W battery hot off the charger. Bafang also make a 250 W motor that has a 1200 W peak (48 V x 25 A)...

Tuna (red) is illegal. Some days that is all there is in the water just offshore! Tuna (white) is 20 miles offshore, the other day there were catches at about 10 miles which is rare. What is really nice and can be caught in the bay is Bonite https://en.wikipedia.org/wiki/Atlantic_bonito. I have...

I am looking for a low thrust (18 lb) motor and on most of the spec sheets they say 15 or 20 Amps, the one in the link is two speed 7-15 Amp. A single 10000 mAh 10C multistar pack can supply 7 Amps without shedding a pearl of sweat. Two in parallel would be a whole week of evenings of squid...
