SkyRC Battery Discharger suitable for Prius Modules?

Too powerful and expensive for a single module... Could be good for multiple modules but then you get confusing data on module health. Try this one instead: B6EVO Charger

 

What are LiMH cells? I assume it is a typo, but pretty poor for a professional manufacturer.

BTW, I have several B6 clones. The first 50W is working OK, both 80W are broken (common grounding error but replacing some fried components didn't fix it). and the latest 80W is so far off (happily charging LiIons at 4.23V saying it is still at 4.15V) that I think I'll just toss it as the calibrationprocedure is so intricate that I probably won't even try.

Moral of the story: I could have gotten 2 original ones for the price of the 4 fake ones I bought. And end up with two working ones instead of my single still-working-clone.

 

It's so strange that modules are so hard to come by in the EU? I wonder why that is? We're swimming in old modules in the US...

 

I'm expecting my skyrc BD250 and i can't wait to use it. I will discharge each of the 28 modules whilst inside the car and then charge them all at the same time. The discharging i expect will be very fast and exact because it can do it at high rates!!!

 

I bought one of those a long while back... Feeling bad I haven't tried it out yet. Sure hope I didn't buy a defective one... What kind of charger are you going to charge the pack with? And go you post the skyrc BD250 discharge data it sends to your computer? Curious to know how easy it is to set up and use?

 

Yes it connects to the pc and it says you can save it as an excel file, save a screenshot. It hasn't arrived yet so I can't tell until it arrives.

For a charger I'm going to use a variac of 500w, a step up transformer, a bridge rectifier etc so I can charge them all in series at the same time. I will be able to control the voltage and of course the amperage with it.

 

Also for a charger I found a beautiful small one called toolkit rc m7ac which to my opinion is excellent because it stops at the exact voltages you set it to. I don't know yet if it can do automatic cycling.

 

What's the range of amp on the Variac and how much did it cost? Got any pics? The temptation to turn up the amps when recharging will be hard to resist... But 1/3amp or less trickle charge is essential in the balancing stage once all the modules are almost entirely fully charged.

 

Amperage? The variac is 500W, here its 230-240v so it should be from 0 to 2 amps max.
Here in europe its euro, so its around 125 euro. (132usd)
I have not received it yet.
Yes, i'd turn it full (at 2 amps) for 3 hours, and then lower it down to 650mA or lower, depending on tempertatures.
I can force it or go soft with it depending on how much time i have.

 

Of course, any load should be ok. I like the idea of graphs and controlling it by sitting on the pc....

 

I think that the above charger youve mentioned can only go up to 2A discharging. Could take too long to do 28 modules...

 

I think the hardest part was finding the pc program at the company's site. It was easier to control things via laptop vs the buttons on the device. Plus you can save cute little graphs for each module.
