Let me ask you, what is the difference between the two?
Do not go for the obvious like size and color, both batteries are the same width and height but the white one is less than half the length.and about half the weight as well.
They are also both the same voltage, but the brown is 14v 3000Mah
the white one is 14v 4000Mah.
In case you didn't know these are lithium Ion batteries.
They charge to the same voltages and discharge to the same voltages, they can be used with the same chargers as lithium polymer batteries but as you can see are much smaller and more durable.
This is because they are similar to AA batteries, they have a metal casing.
This means any crashes are less likely to kill your battery.
So I will be building these packs to sell on for you guys.
You can build them yourself if you like just have a google for some sources to buy the cells from.
I am planning to sell 4500Mah 4s size wise they are a tad smaller than a 2200Mah 3s Lipo and a bit lighter.
I am aiming to sell them for about £8-£12, a equivalent lipo
(cheapest on hobbyking was £21.50)
And 4s 1000Mah
This is about half the size of the white pack above.
The reason i wont be selling the white pack 4000Mh 4s is due to supply issues but i may in the future.
but in the future i want to expand
and custom batteries will also be on the agenda.
If you are interested in these packs, have a look on blog history, another member of DIYdrones has posted about them previously,
and if you would like to buy a pack now, i will start selling the 4500Mah packs in about 3 weeks after further testing and built technique experimenting.
Just PM me.
