HK Battery Charger
 
Has any one used this charger from HK Turnigy MEGA 1000W 8S 40A Lithium Polymer Balance Charger. And if so is it any good

I have a hobbyking charger as my main charger. I only use 2s and 3s on it because that is all that I have. When I finish balance charging a 3s on it, the third cell is always over voltage (4.22v). So if you get a hk charger, be careful because the tolerances aren't great and i have no way to correct the finishing voltage (believe me, I've tried).

HK sell many different chargers so you cant tar them all with the same brush.

The Mega 1000W sure looks like a lot of bang for the buck. The only reservation i have with the spec is that the balance drain current at 200mAh is extremely low for a powerful charger. Even the little Accucel-6 has 300mAh drain current. This means that on larger batteries or if parallel charging, balancing could be a very slow process and if the battery is too far out of balance the charger might fail to complete the balance cycle and just time out.
Good chargers of similar power usually have at least 0.5A balance drain current and for the best chargers it's 1A or more.

You were to fast there, two typos: mAh (unit of capacity) should be mA (unit of current).

Seems a bit over the top for a beginner. What batteries do you want to charge, voltage and capacity?

Price to advertised capabilities it looks like a very good charger that will be difficult to outgrow.

Its possibly a good deal but some of the Turnigy chargers are great and others are junk.... I wouldn't want to be the first to give it a review. Let other people do the testing.

That 300 mah balance is direct from the HK web page.

As for chargers in this power range check out the Cellpro powerlab 6 with the same 1000 watt rating, and about 1/3 more $$$$.

I have two '8 chargers, a number of my club members have various Cellpro chargers. They work quite well.

I know you know :) but I'm always a bit (over)cautious with regards to beginners. Especially when (dis)charging is the topic.
