Hobbyking don't stock a suitable charger for the Flightmax, I take it Ian? I'll keep an eye on the New Arrivals page. Thanks for your help.

Could anyone recommend a website where I might order a Battery Management System and a charger for a pair of Flightmax 4200mAh 4S2P 30C LiFePo4 Pack batteries I just absent-mindedly ordered, please? I am planning to connect a pair of these 13.2V batteries in series to power a 450W 24V 3000RPM bicycle motor, and I haven't thought of the charger yet. What is even more thoughtless, is that I don't know whether I'll beed a BMS (or two) nor what specification to look for if I did. Any advice would be greatly appreciated.

You cannot suggest other website on the hobbyking site. If you keep an eye on the new items page you'll see BMS appearing shortly.

What does the 2P stand for in 4S2P?
 Alan 8 points
The S and the P stand for Series and Parallel. So, a 3S1P 1000mAh pack has 3 cells in series, making a 11.1v 1000mAh battery (assuming its a Lipo pack). A 1S2P 2000mAh pack would have 2 cells, but they would be put into parallel, which does not increase the voltage, but would double the capacity. This would mean that it actually had two 1000mAh cells in the battery. So, a 4S2P pack actually has 8 cells, and in this case, each cell has 2100mAh. It has two sets of 4 cells in series that are then put into parallel. I wish I could make a diagram, because it is so much easier for me to explain it that way. Anyways, I hope that this answers your question. A 4S2P pack will act just like any other 4S pack, its just that it actually has 8 cells inside it.

I bought this battery for my traxxas slash to upgrade from my 7 cell nimh batteries & WOW...WHAT A DIFFERENCE!!!!!!!! (keep in mind that the stock esc cannot handle this many volts) this battery has great power & runtime for a great price! I was afraid of lipos because of the fire hazzard so I went with these life batteries & I'm very pleased! you'll need a lifep04 compatable charger, I use the thunder AC6 & it works great!
