When charging a 4s 5000mah with that charger he could probably get 6a out of it because of the low watt limit. Technically that does fall within his original requirement but later on in the thread he talks about getting a second charger.

{shrug} I use that one for all my batteries (2s-4s) and it seems to work great. easy setup and easy to swap between modes. Reports 8.0amps just fine!

If you're charging a 4s lipo at 8a with this charger and the charger is actually putting out 8a then the info on dynamite's website has to be wrong. They're saying it's only a 100w charger. 16.8v x 8a = 134.4w

My brother-in-law had that charger and didn't like it since it lacked a storage mode for lipo.

If the charger has a 100 watt charge limit

At the start of the charge cycle you may indeed see 8 amps

100w / 12v = 8.33 amps theoretical maximum (obviously limited to 8 amps)

However at the end of the charge cycle you will not

100w / 16.8v = 5.95 amps

From storage voltage 3.85v / cell you will only see a maximum of 6.5 amps

100w / 15.4v


For the price of that charger he could pick up one (and a separate PS) that is capable of double that output

Will charge a 5000mah sized 4s pack at 10 amps

This charger is good only for light duty charges. My 2S 5000mah battery maxes out the charger at 8.5amps on an AC source.

I suggest buying a high end charger once and be done with it.
Im running the TP820 in the field while the 610 ac/dc is in my pitbox for backup.
Im running the hobbypartz power supply also.

Also keep in mind, that battery capacity are likely to oncrease (as that what history have shown the last years... We already have 6000+ mAh). So later on 2C might equal 14 amps... So it might be an idea to get a power supply with plenty of amps up front.

Double post :)
