Recommended batteries for my use?

[Loylipop]

I'm currently using a WISMEC rolo RX200 with a TFV4 mini tank or aromamizer rdta. vaping at 50-70 Watts. I've been experienced charging problems and from what I read, its because of the USB charging on the RX200, it screws with the lifespan of the batteries. I've just got an external charger for my batteries but now I need new batteries to replace my old almost dead ones.
What are the best batteries recommended for my usage?

I think any quality battery will do you fine. Samsung 25Rs, LG HG2/HE4s. IMO just do your best to stay away from the vaping brands since they tend to lie about their specs. Sometimes dangerously so.

Quality 20A batteries are fine for your use.

Samsung 25r
LG HE2, HE4, HG2
Sony vtc5

I wouldn't bother with other brands.

This, LG HG2. 20amp, 3000mah being the Wismec is triple battery series.

200watts/9.6volts lowest battery charge voltage= 20.83333 amps maximum it can pull
Your application
70watts/9.6volts=7.2917amps max you are pulling

Even the Samsung 30Q (15amps CDR, 3000mah) would work in that application, you'd never get above 144watts with the 30Q, but the longer mAh ratings work for longer run time, especially at lower settings like you are using.
