Mini Review 4s 2600 mAh LiPo Battery from YellowJacketsRC

[gyro]

Going to be doing a mini-review and some testing on the @YellowJacketsRC 4s 2600mAh LiPo battery!

First, the specs below are from http://www.yellowjacketsrc.com/store/index.php?route=product/product&product_id=52

4 cell 14.8v 2600mah Lithium Polymer Battery
25c continuous discharge rating (65A)
50c burst (130A)
278 grams

1) Capacities measured at: Charge: 0.5C, 4.2V, 3.5 hours max or 0.02C cut-off; Discharge: 0.2C to 2.75V

Here is quick unboxing pic. The battery was wrapped in some bubble wrap inside the box.


Now, the specs say 25C on the website, but as you can see, the battery received is marked 40c... Not complaining!

Onto the scale!


So just a pinch (10g) heavier than listed on the site. However, compared to a competitor battery, the Tunderpower G4 4s 2600mAh 30c, it's almost exactly the same weight!

As you can see in the comparison pics, the YellowJackets pack is a little thinner, and longer when compared to the thunderpower pack.



Also, and I think this is actually something you can see in the pics, the YellowJackets pack is a little more "dense" in that the shrink wrap appears tighter, and the cells themselves feel a tiny bit more firm.

More to come soon, plans to fly tomorrow!

Very nice. I've been testing the 40 2600 yellow jackets as well and they're holding up fantastic. I've been quite hard on them for months now and they're good as new. Got a little over 100 cycles on each pack so far.

Got a chance to fly again yesterday... YellowJackets are holding up great.

Some initial observations:

Absolutely no difference in flight between the YJ's and the TP's.

Love the fact I can 3c charge the YJ's all day (and 5c if I need to), whereas the TP's instructions say 1C ONLY.

So far so good, next up are some static output comparisons.

I got several Yellow Jackets and they are doing very well.
