想買叉機, 有咩平靚正推介?

PowerLab 如何?

請問如用PL8v2＋MPA同時充６排鋰電, 分別是２排5000mAh、２排6300mAh及２排6800mAh，這樣可以嗎? 謝!

只要所有電S數一樣就可以，參考翻十三樓我個post

多謝賜教!

Powerlab完全不附電學原理，買咗就中伏。

C Hing, 此話何解?

部機只出兩條大電流差電線，轉接板上無control大電流線路。所以只能串聯差電，六排電串聯後充满要差吾多50V ...

明白晒!! 多謝賜教。

翻查powerlab網頁, MPA adaptor 是用 parallel charging , 意指並聯, 那麼六排2s 7.4V鋰电同時間用並聯方式充电, 其總电壓值应没有50v那麼高吧？

I see. As checked, the diagram you've posted in Configuration C from the User Manual of PowerLab 6/8. However, I'm thinking charging from MPA adaptor might be difficult in terms of safety that you've concerned. MPA is equipped with 40A fuse for each of the connecting slot so I think if there's something going wrong, the fuse should help.

It's true that the balance jack supports 3A but it's replied on a condition. When the battery is only connected to the balance jack and other power lines are connected from the charger to the battery. If everything is connected (power lines and the balance jack), the charger can then deliver the charging current as you've adjusted.

When using the MPA adaptor charging 6 lipos of same number of S (Cell numbers) and same capacity, that's the perfect situation. Same S but different capacities, what I've got from the manual and some overseas forums talking about PowerLab chargers, the charger can still function but will target to the lipo with the smallest capacity, that means some of other lipos might not be fully charged when the charger appears to finish the task. So we need to check and charge up those not fully charged lipos in a second round charging.

This is what I've got from the manual and forums and hope this can favour our discussions.

A lot of typo errors, sorry!!!

The balance jack supports 3A charging when that is only connecting the charger and the lipo while there are not power lines connecting the charger and battery.

Brother fbs, not truly understand your meaning. Perhaps I trust the fuse there to protect not only the adaptor and charger, the battery should count in too. I think your first half statement is correct and I totally agree. That's why the MPA adaptor will perform the best function when handling maximum 6 packs of lipos with same cell numbers and capacity. As said before, MPA adaptor is designed for this.

Brother fbs, have you tried this charger before. I think I'll give it a go. I've handled the worst chargers and transformers in my life and surely I won't rewrite my own record after using this.
