LiPo, whats the difference?

What is the difference between a ;

5000mah 4S 45C

5000mah 4S1P 45C

Thanks

Tim what batteries? More then likely if looking at hobbyking they will be a 1p. It all has to do with how many cells in the actual pack and how they are wired.

They mean the same thing. Usually a single 4S pack. But in a boat set up, both could also represent two 2S packs wired in series which gives you the same voltage as a single 4S pack. I run that configuration in my P-Lim Sport Hydro.

To further discuss.. Take 2 7.4 volt batteries. Wire them like this:

1. Positive on batt 1 goes to esc.

2. Negative on batt 2 goes to esc

3. Positive on batt 2 plugs into negative on batt 1.

You now have a series connection and have 14.8volts

Take two 14.8 volt batteries.

1. Postive of batt 1 to postive of batt 2 together and into esc.

2. Negative of batt 1 and neg of batt 2 together and into esc.

You now have a 4s2p (Parallel connection 14.8volts)

Use just ONE 14.8 volt battery and you have..

4s or 4s1p connection (14.8volts)

Very nice Jim thanks for sharing.Gill

Is one a better way to wire while running (in parallel or series). What are the advantages or disadvantage?

Thanks

It depends on what you want. If you wire two 2S packs in series (7.4 volts each) you have 14.8 volts or 4S. If you wire the ttwo 2S packs in parallel you will still have 7.4 volts but you will double the capacity. For examle, you have two 2S packs with 5000 mAh capacity each. Wire them in parallel and you have 7.4 volts and 10,000 mAh capacity.

Here is a great thread discussing LiPos etc. http://www.rcuniverse.com/forum/m_9069147/tm.htm
