2 x 36V 10AH Lifepo4
« on: December 17, 2008, 10:05:37 AM »
I have a standard 36V 10ah Lifeop4 battery.......Can I connect another(36v 10ah) to get 36V 20AH by just connecting the two - & + wires. I know I will still have to charge each battery indiviually. Cheers.....

Short answer - yes.

If the batteries are identical you can make it into a 36v 20ah by connecting in parallel or if the need arose a 72v 10ah by connecting in series.

Thanks Muzza
I don't know "parallel" or "In Series" means though I'm sure my local Auto Electriction can do (I don't need 72V 10AH).....Cheers & Happy Xmas

####################################################
red---------(+)-----(+)
               pack1    pack2
black-------(-)-----(-)

Parallel is where you split your lead wires so you have a red on each plus
and a black on each -, the available amps are added, so if you have two
20AH 36Volt packs, you would have 40AH at 36Volts.

#################################################
red---------(+)
               pack1
                 (-)--------(+)
                              pack2
black------------------(-)

Series is where you connect Red(+) on one pack to Black(-)
on another pack, then connect your Red(+) Lead wire to
Positive on one pack and Negative on the other pack.

This gives you the same available amps (20AH) but the
voltages are added to get 72Volts
