Lipo battery capacity question

[doobedoobedo]

I never trust ratings where burst isn't twice continuous. It is all down to whether an engineer or someone in the marketing department rates them. Turnigy do seem to be better than many others with their ratings.

The way we use these batteries - a few short bursts, leave it for a bit, a few more bursts is much gentler than if they're in a car or a plane where they're running flat out for long(ish) periods.

Turnigy are known for being shit hot with their classifications... Why? As they have to be since they're mainly designed as racing cells.
Hence why I love my Hard Case packs.

Yep, we all know how Raguri loves a hard one...

When looking at multi cell lipo packs it helps to work out the Wh of them to make comparisons. Yes a 3S 1000mAh lipo pack holds the same amount of power as three single 1000mAh cells but that doesn't make them 3000mAh, they are still 1000mAh. The three cells would need to be linked up in parallel to make them 3000mAh.

The pack you linked to for an example. Watts equals Amps times Volts so

1300mAh times nominal voltage of 11.1V gives you 14430mWh divide the mWh by 1000 to give you Wh leaves you with 14.43Wh

Compare to say a Samsung 25R, 2100mAh times nominal voltage of 3.7V gives you 7770mWh or 7.77Wh

Thanks all for your replies it's making much more sense now Time for a lipo build (funds permitting, cos a bit overspent atm).

I'll need a charger too if anyone can recommend one that they are using that wud be useful as there are soo many to choose from all with similar specs.

You wouldn't need anything too powerful for the size of packs you'd be likely to use for vaping. Like you say there are a lot of options for chargers at around the 50W max for 1 to 6S packs, way more than you'd actually need. It's a while since I've bought one but I think if I was I'd go for this one, not too expensive and a load of features that could be useful if not now at some point in the future. You could probably go a bit cheaper if you needed to but I reckon that's good value for the features you get.

That's a good charger, built in power supply too. The IMAX B6 is the daddy of hobby chargers.

I have one of these and the old version of this one - before it was LIHV capable they need a 12V DC power supply. I use an old ATX PC supply.

Yeh handy being mains or 12V for sure. All my chargers are 12V but I've never bothered with a power supply, my leisure battery stays hooked up to a maintenance charger and I just hook up to that at home or at the field. I have to say LiHV I don't know much about, never had the need to look into it much.

Yeah was looking at the imax. The others look ok too. Thx

So now i just need to get a list if bits together for my build
