Default New Electric Advice

Hello All,
Getting back in to flying after many years away from glow. Going the electric route this time, and need your advice on what which brands of batteries and chargers you all prefer, and why.
I have the E-flite Cirrus SR22T 1.5mm BNF plane, and Spektrum DX 8 Gen 2 radio, and am looking for about 3200 3S batteries and charger recommendations.
Thanks for your help and would love feedback from your experience!

Battery, Good Quality Tower Lipo 3cell 3200 mah 30C https://www.towerhobbies.com/cgi-bin...p?I=LXJGMT&P=7

Charger Good Quality A/C D/C Balance Charger https://www.towerhobbies.com/cgi-bin...?I=LXEVDY&P=ML

There are some nice lipos and chargers from Hobby King in China that are cheaper, but shipping from China is a issue right now, they dont have enough planes to fly into the US because of the corona virus, I bought some items from china on EBay and they are all being Delayed Big Time, so Buy from the USA for now.

There's a ton of battery brands out there, and the majority of them are good quality and similar performance. My go-to brand is RoaringTop. Their warehouse is in LA and they ship Priority Mail, so they get here quickly. Their packs typically weigh less than other brands, so the 3S 3300 35C may be just right for you (and you can choose a Deans or EC3 plug):

Testresults are getting posted/referred in first posts
Marketing 'optimism', nonsense, stickertuning and the outright C-rating lies, with tests

Plenty of charger tests under 'Loader tests'
translate...www.elektromodellflug.de
Also battery, controller, motor, power supply, electronic, plane etc. tests.

Some well-structured reading for rainy/windy days, including two online booklets for beginners, and some handy e-tools as well.
Will save you, and us a lot of questions, and probably a crash or two. Notably the 'what went wrong?' kind of questions
Will also prevent you from burning up several controllers and/or motors and/or battery:
E-flight primer and tools - RCG

And pleasepleaseplease, do your RC equipment, wallet, ego, battery, controller, motor, house/garage/car a big favour ... get a watt-meter.
It will more than pay for itself, will save you at least one fried motor and one fried controller. Will also help you finding the best setup.
Keep battery-/-watt-/multi-meter wires short!
too long wires batteryside will kill ESC over time: precautions, solutions & workarounds - RCG

You look at charger max. charge current and max. voltage of course. But what manufactures/sellers usually don't tell you is that most chargers cannot achieve those two maxima simultaneously, because that would exceed charger max.power.
This results in your charger not achieving max.current in that case. Not a disaster or bad perse, you just have to wait longer.
A better explanation by Bruce Simpson

A B6 or B6AC 50watt charger can handle your pack at 1C: 3.2A, 12,6volt, 40watt. The B6AC can only handle 50watt from a (battery) power supply, not from mains.
Available under several names and looks. There are 80watt versions around as well. Or quad versions, 4 chargers in one casing.

Another thing to consider, what are your plans for the future, current-, voltage- and charging power wise?

Two charger selection/calculation tools
Script Asylum

→ RC calculations
→ electrical
→ chargers
(2 menu items)
The other menu items and demos are also veeeeery handy/instructive for e-folk, add site to your favourites?
Brian G. pulled the plug on his ScriptAsylum site, I copied it.
