429 (4170mAH) - 7.29 - 7.8

428 (4161mAH) - 7.29 - 7.9

5200/24C:

534 (5191mAH) - 7.35 - 6.6

537 (5220mAH) - 7.37 - 6.4

If I'm reading that right, the 5200 pack shows slightly better average voltage and significantly better ir (1.2-1.5 better)? I've been running Lipo long enough that I'm a bit foggy on battery numbers.

Hey David,

Not Danny by any means but generally what everyone has noticed is that with Lipo's a higher MAH battery will always be better as long as your comparing brand to brand (Smc to SMC, EP to EP, IP to IP) and comparing the same C rating to C rating (35C to 35 C, etc).

Its a little strange looking at because everyone was so used to looking at NIMH cells where if you had higher runtime or MAH you usually had lower voltage.

Yep, I get that part (ie. 35c=35x the battery's capacity current/amp output). I guess by the "new math", higher capacity is always going to perform better, in every way than lower capacity with lipo.

Any recommendations for an inexpensive stand alone balancer for the 5200 packs?

Thanks!

For a balancer that you will plug with your charger you should you can get and Atroflight Blinky , Common Sense also has one and the Electrifly Eqquinox.

Our Balance connector is the JST-XH.

Tell your Hobbyshop to order our packs from Horizon if Great Planes is out of stock. Were getting a new shipment in this week and will ship out backorders.

Oh? I thought I read somewhere that the blinky didn't work with Align type plugs?

I'm pretty sure it does as my friend who flies Helis uses our 800 packs and they have the JST-XH connector and he uses a Blinky. You may want to email Astro Flight to make sure as my friend could of altered something.

Yes, a Blinky fits the balance connector fine. I use it on my Lipo every few cycles (it's a 28c 4000, but I'm pretty sure the balance connector's the same as on the 24c packs).

Thanks for the info. All our car packs have the same balance connector.
