New product in stock: 7000 mAh LiPo battery with JST connector

LIPO7000

BATTERY-LiPo7000mAh is re-chargable Lithium Polymer battery with over voltage and under voltage protection circuit and JST connector for all our OLinuXino, OLIMEXINO, PINGUINO, Duinomite boards.

This battery when attached to OLinuXino OSHW computers will allow them to run without external power supply for all day long. Normally OLinuXino consumption is between 0.2 and 0.5A depend on workload this means with this battery fully charged they will work between 14-35 hours stand alone.

Note that these LiPo batteries are considered dangerous for transportation and we can ship them only with ground service like DPD, UPS Standard, TNT Economy, which limits the shipping options to just EU.

LiPo shipment problems with Airmail

Ourr Aimail post service is delivered by DHL Global Mail. Yesterday we got notice that their scanner detected batteries in one of the shipment and they stop and return in back.

We have heard that some carrier refuse to deliver LiPo batteries are they are classified as dangerous goods, indeed LiPo batteries could cause fire if punched, LiPo are excluded as goods for DHL normal service too.

So far the road services like DPD and UPS Standard do not cause problems to ship batteries, but now we try to figure out how to exclude DHL and Airmail shipping as options when batteries are put in the basket for ordering. Until we come with solution we will just manually stop such orders, so please do not order batteries with DHL or Airmail unless you want your order to be put on hold.

We got in stock three new types of Lithium Polymer batteries: 3000mAh, 4400mAh and 6600mAh, all they are 3.7V and compatible with all our boards with LiPo chargers like: OLinuXino A13, A20, Olimexino-328, Olimexino-STM32, Pinguino etc.

6600mAh is real monster and can backup as UPS A13-OLinuXino to work without external voltage for 20 hours under full load.

The products are available in our web shop in Power supply category: https://www.olimex.com/Products/Power/

All battery packs have protection circuit for over-voltage and short-circuit.

A13-OLinuXino REV.B works fine from LiPo battery

Image

At first we couldn’t decide if we should make A13-OLinuXino to work from Li-Po battery,  this seemed to be just increase of the BOM and price, so we made REV.A without this feature.

Later though we decided that this is nice feature and we re-considered and included this feature in Rev.B

Now A13-OLinuXino Rev.B is assembling and we got some of the first boards to test with LiPo battery, the result is A13-OLinuXino now may run from single LiPo and support USB devices too thanks to the included boost DCDC.

EDIT:

Some current measurements were taken while board was powered with 3.7V standard 1400mAh LiPo battery we have.

Without LCD the board running Android consumes between 200 and 550mA depend on the different activities, when LCD is add the consumption rise with 450mA due to the backlight.

When the board is in power safe mode the consumption drops to 3mA.

So the A13 while running at 1Ghz takes just 2W power
