Cycle life estimates are halved if fast charging always deployed: recommend a mix of standard and fast charging as the need/opportunity arises

Warnings: TrackPower Lithium Polymer has a far greater energy potential than older/ traditional battery technologies used in RC. Treat Lithium Polymer batter technology as FLAMABLE SOLID FUEL. ALWAYS use a LiPo charger set to 2-Cell / 7.4V LiPo for this 2s1p pack. NiCd/NiMH “delta peak” chargers are COMPLETELY UNACCEPTABLE for LiPo technology and WILL cause a fire. Failure to observe maximum and minimum ratings and the warnings stated here an on the reverse of each pack will achieve NO PERFORMANCE ADVANTAGE, will VOID WARRANTEE, and will lead to UNSAFE OPERATING CONDITIONS. Practices such as pre-race Peaking and Zapping are unnecessary and must be strictly prohibited for LiPo Tech owing to their immediate danger in the context of LiPo chemistry.

There have been enquiries and one of the most common question is about it's high speed charging. TrakPower 4900 can be charged at up to 10amps on a lithium capable charger.

With true convenience, you can fully utilise your equipment instead of having to waste time and additonal money for high rate dischargers, individual cells dischargers, etc. All you do is after a run is to plug it on the charger to fill up the pack with electrons again. Compare it with nimh, whereby you have to wait for the sizzling hot pack to cool off and to discharge it properly before being able to charge up again.

For a competitive raceday, you will need 5-8 packs of nimh cells? not to mention a ton of supporting equipment to ensure the packs will still be able to deliver for the next charge? Consider TrakPower 4900, only 2-3 packs are required and i'm state that as a very big margin. now add on the convenience, add on the lighter weight, not having to worry about dumping? Just take the additional power as a bonus!!!!

Spend more time surfing thru the pit area making more friends, sharing more setup tips, enjoying yourself instead of having to worry about whether your nimh is done discharging.....
