Re: DNA200 mit Lipo - Ende bei ca. 20 Prozent

nordic09 Do not change anything. The LiPO battery runs out at 3.00 Volts. Less than 3.00 Volts will damage the battery (batteries). It is better to have a margin of error than to damage some of the batteries in the pack. DNA 200 / 250 / 250C, has an efficiency of 97 and 98%. If you want 15 Watts, yo...

Re: Wie finde ich den richtigen Akku?

Hi shadockan, thanks for your post. I'm a little bit confused. You say: So if you ask for 50 Watts, you will be marginally efficient. Nothing will happen, but in relation to the batteries VTC6 30Q HG2 you will have a higher voltage drop, with the result that the 500mAh larger capacity will not play...

mk my friend ..... I found it ....... In the end, you were right. --- * But that changes everything ..... * --- Therefore, the Sony VTC5A is not at the same level of security as the Moli P26A Samsung 25S LG H26 But the Sony VTC5A is not just called NCA as the picture shows ... (link) It's called NCA...

Re: Wie finde ich den richtigen Akku?

Something is wrong. Sony VTC5A can't be NCA ..... The chemical composition of the Sony VTC5A is ..... Li (NiMnCo) O² It is an INR hybrid battery  , of the NMC (NiMnCo) subgroup . The chemical composition of NCAs is ..... Li (NiCoAl) O² NMC and NCA batteries are called hybrids ( INR ) batteries and h...

Re: Wie finde ich den richtigen Akku?

Ginger my friend ... Tables and numbers as a theory are something you can't think of as standard. Take for example three batteries capable of 15A output. Sony VTC6 Samsung 30Q LG HG2 These batteries can deliver 50 Watts from 4.20 volts to about 3.30 - 3.40 volts, with DNA 75. ( Depending on the loss...

Re: Wie finde ich den richtigen Akku?

Joergl my friend ... Mechanical devices also have losses ... (of course you know this better than me ...). Smaller of course than electronic devices. If you look at the technical features of these boards, you will find it. These are statements of construction companies. Of course, the percentages ar...

Re: Wie finde ich den richtigen Akku?

The Amps-Watts relationship is not entirely correct. If we are talking about an electronic device, we should also know the efficiency of the circuit. A device with 85% efficiency (for example DNA 75) will be needed 1 battery 50 W (power) 85% (efficiency) 19.61 A (current) If we take it Dicodes FL80 ...

Re: Sony | Murata VTC5D 18650 2800mAh 25A Battery

The Molicel P26A and the Samsung 25S are marginally superior to the drop in voltage.

I expect to see the comparison between the Sony VTC5D and the Molicel P28A ...
