I am trying to find a good 1300-1500 mah 3s-4s battery + compatible charger. It will be powering a 250 sized quadcopter with 5 inch props, 2300 KV motors and a F4 flight controller.

Please recommend good options.

Thanks

I am about to go with tattu 1550 mah 4s battery . Which balance charger do i need with it?

At the very least get an Imax B6. If you can spend some more then get one of those iSDT chargers.

I don't think you should go for any Imax or general 4 button charger. I am having a genuine Imax b6 mini but still it has problems. First of all the voltage is not calibrated which results in overcharging and over discharging of some cells. Secondly, there is a design flaw that some people  have experienced (including  me) that the internal resistance of cell 1 is showed higher than the actual value which leaves you confused of your battery health.  All this is my personal experience and I don't recommend the 4 button chargers. Instead the ISDT chargers like the Q6 lite are a better option if your are on a tight budget and other models as well. I'll also be getting one of them soon...

Or a new charger from Skyrc is the B6 Nano. Not many reviews yet but seems nice. Also has inbuilt Bluetooth and can be controlled by your phone. The form factor is like the ISDT Q6 series.

isdt q6 and skyrc b6 nano are both close to Rs 4000. Thats twice the price of the battery. And more than the price of the FC + ESC combo.

please suggest something cheaper
