Should have googled it first Lol.

Kind of. We have 4 hours of full sun yesterday. Thats 4 hours this year.

Noted, regards all. BTW I wasn't aware that Li ion and Lipo's were a different chemistry. As is always the way with a new project, you learn something new every day.

Oh, I'm a total noob. I bought 'My First Solar PV Kit' from Eco-worthy on saturday and it's still working. On a serious note, it is more of a demonstrator than a practical setup although even though I havent seen the sun in 5 days it still seems to put some charge in my battery. My initial...

Noted and tested as such.

Actually the drag from the motor is not inconsiderable. I have to have the power setting at 1 on level ground and rarely go below 2. I wonder if there's some kind of regeneration going on but I've no way of testing it.

1. Should panels always be under load is or no connection no flow of current (i.e isolated on a DP switch). 2. Fire risk. Plenty of vehicles go up in smoke. What's the risk with a PV setup? 3. Cheapass alibaba 3.2v cells. Buy or avoid?

1. Someone on the forum 2. No. there is no reference to connecting anything other than 'a 10A load'. 3. Putting a lightbulb on it isn't specific enough an instruction. What I can say is when I connect all the breakers, i.e., allow the charge controller 'access to the battery' I get a fast...

Addendum. My battery is a 504Wh.

I watched this video: He suggests that trickle charging is bad but doesn't explain why. So I googled: lifepo4 trickle charge issues and got this...

Well my bike was 'promoted' as using samsung cells (i presume 18650's). Ive done approx 600 miles over 2 years- it's a 2 grand shopper. I would hope for another 600 but the clock is ticking and as I previously said a replacement on a 4 year old ebike is prohibitively unnecessary...

Have to disagree. A new batt, last time I looked, was 350 quid. A 180W panel and the 6 quid controller I have is less than 200. As Scottish Lenny says it might be cheaper to build my own batt pack. BUT, installing a charging system now might extend the life of the current bat if I'm not...

Do I need to isolate the controller from the battery when using an inverter that is connected directly to the battery? My controller is a cheapo 10A 12v so I am assuming it'll overload the controllers 'load' output.

Do I need to consider vibration or shock loading for a small system in a bicycle trailer?

I appreciate this is a poverty level/noob kit but I would expect the controller to continue to attempt to charge the battery. Am I mistaken in this assumption.

Well, as it happens, over here only 250W bikes are legal and that's what I own. I'm charging it now and the charger is consuming 0.6A at 89W on 238VAC. The maths don't actually stack up and the charger output says 48V at 2.0A.

I stand corrected: https://eovolt.co.uk/collections/batteries-motors/products/eovolt-confort-20-bike-spare-battery FUCK THAT. So Kravitts' comment makes more sense. Oh, range 20 miles max at full power on flat ground. Basically eovolt; Range 70-100km. You're talking bollocks.

read my last...

Mmm, a 180W panel is 1m long. Add another metre for mechanical bollockage and it might be 6 foot long.

roger.

You had me all the way up to 'You'd'. While I admit it'd be cheaper to buy 'the right size wire' than the insurance premium for fire damage I think I can get by with this one. If it doesn't work out I promise I wont site your comments in any litigation.

QDog, in your image I have breakers between the panels and the controller and the battery and the controller. Other than that, my setup is as shown. My original question was; do I put the charge controller 'under stress' (or using Rocketmans' parlance, a 'loop') by having an active load on the...

Everything went a bit blurry after that

I was winding you up a bit. At 12v and 10A I dont thing I'll have any issues but on a physics level (I mean without testing it- to destruction) I wondered what effect it would have. I did electronics at O level 40 years ago. It hasn't weathered well. :)

If I have some thin wire and I want it to handle more current can I simply get three lengths, trim the sheath off at the ends and twist the bare wire together at the ends to 'make one thicker wire'?? Or doesn't it work that way?

As the appliance is only drawing 6A I've successfully used the inverter through the charge controller load output. So it will charge from a panel while discharging the battery.

The objective would be to provide charge/discharge parity but as already discussed the technical challenge is reasonably a stiff one. On the upside, as discussed, its resaonably flat around here so full motive power would net 18mph max but 50% power is perfectly adequate (gives around 12mph) and...

Looking forward, is there a shunt/meter combo that I can use as I upgrade/scale up a system? I currently have the 12V10A/25W system from Ecosomething. Sooner or later I will assembly a 24V system with proper batteries to service higher loads. Does a 'load measuring' device exist that can, for...
