4-Max Professional LiPo Batteries

Up to 60C Continuous / 120C Burst
Up to 5C Charging Possible

• 25/60C Continuous, 50/120C Burst
• Up to 5C charging
• High performance, minimal voltage drop under heavy loads.

These are not your cheap low performing Lithium Polymer Batteries.
They are high quality, high performing LiPo batteries on par if not better then the established well known quality manufacturers.

Because our batteries hold their voltage extremely well under load you fly on less current which means longer flight times. Don't believe us, here is an example

Cheap Chinese Battery
200W to fly, volts drop under load to 10.6V therefore Amps = 18.86A

4-Max 4-Max LiPo Battery
200W to fly, volts drop under load to 11.6V therefore Amps = 17.24A

1.62A = 8.6% reduction in current needed to fly = Longer flight times and as our batteries hold their voltage far better under load this also means an increase in power as higher volts = higher RPM = more power.

Please Note
Although some of these LiPo's can be charged at 5C, for extended life we recommend charging at 0.8C - 1.0C.

All the batteries have a JST-XH balance connector as used on nearly every modern charger.

All batteries are supplied with JST-XH balance connectors but no connectors are supplied on the main power cables except for the small capacity batteries marked with a *.

The batteries come without connectors fitted on the power wires and the end of the wires pre-tinned with lead-free solder. Lead-free solder in our opinion is rubbish and therefore we recommend that you snip these power wires back (one wire at a time) until you have nice fresh solder free wire then solder your connectors of choice on with good old fashioned leaded-solder. You will need a high powered soldering iron. We recommend 50W or greater. We have some available here if necessary.

Please Note Due to having our knuckles severely rapped by the Post Office we can no longer send any kind of battery via the post. Any order containing batteries will have to be sent via courier and this will incur a minimum of a £9.99 delivery and packaging charge.
We cannot deliver batteries outside of mainland UK
