As of December 6th 2006, Thunder Power produces 16 different cells, both in their Pro Lite and eXtreme series batteries, to meet the widely varying needs of R/C modellers. Whether you fly radio control airplanes, drive rc cars, or boats, there’s a Thunder Power cell for you. This article will help you choose between them.
Thunder Power’s 350mAh Pro Lite 18C cell is their smallest. Offered only in 2s (22g) and 3s (33g) packs, this cell is meant for the smallest indoor airplanes. Common all-up-weights for a 350mAh-powered airplane are 3-6oz. These packs are available with a JST connector or with bare leads. A balance connector is not available, so max charge rate is 1C.
The Thunder Power 480mAh Pro Lite 15C cell is just a little larger. Offered only in 2s (23g) and 3s (34g) packs, this cell is meant for small indoor airplanes. Common all-up-weights for a 480mAh-powered airplane are 5-8oz. These packs are available with a JST connector or with bare leads. A balance connector is not available, so max charge rate is 1C.
Thunder Power’s 730mAh Pro Lite 13C cell bridges the gap between indoor and outdoor airplanes. It’s small enough for an indoor plane, but large enough for an outdoor plane. Common all-up-weights for a 730mAh-powered airplane are 7-13oz. It comes in 2s (34g) and 3s (49g) packs, and is available with a JST or with bare leads. A balance connector is not available, so max charge rate is 1C.
Thunder Power’s 910mAh Pro Lite 16C cell is for small outdoor airplanes weighing 9-15oz. It is available in 2s (46g) and 3s (65g) packs, and with a JST or bare leads. A balance connector is standard, so max charge rate is 3C.
The Thunder Power 1320mAh Pro Lite 13C cell can fuel a lot of very fun 10-20oz airplanes. The two 1320mAh packs are 2s (58g) and 3s (85g). A balance connector is standard, so max charge rate is 3C.
Thunder Power’s 2000mAh Pro Lite was released in early 2005. When it came out its performance eclipsed the competition. It had lithium polymer’s incredible energy density and revolutionary power density. It also premiered a second revolution: the balance connector. To this day, no one – not even Thunder Power – has been able to better it. More recent batteries do offer considerably better power density (higher voltages under higher loads), but that is at the expense of energy density (they weigh more for the same capacity). The 2000mAh Pro Lite cell remains the best choice for any model that has to run longer than 15 minutes, and a very competitive cell for 12-15 minute run times. Because of its performance, Thunder Power uses it in a huge range of packs, from 2s1p 2000mAh to 5s4p 8000mAh and 10s2p 4000mAh.
Some of us have seen electric aircraft with stunning performance. Key to this performance is a high C rating and high power density. Thunder Power’s take on this is the Pro Lite 2100mAh cell. Rated at 24C burst, this battery attracts attention from the glow crowd. It is available in 2s, 3s, 4s, and 5s; and in 1p (2100mAh) and 2p (4200mAh). A balance connector is standard, so 3C charging is available.
Thunder Power has developed a cell specifically for the T-Rex 450. It is the eXtreme Series 2070mAh, in 3s form. This cell unlocks the extreme performance possible with a T-Rex, and will do it over a long cycle life (the T-Rex is known for killing other cells faster than usual). The 2070mAh eXtreme Series cell is available in 2s, 3s, 4s, and 5s, all with a balance connector and 3C charge rates.
Thunder Power’s eXtreme Series cells – 2200mAh, 3300mAh, 3400mAh, 3800mAh, 3850mAh, 4500mAh, 4600mAh, and 5000mAh – are all about power. With 22-25C continuous and 50C burst ratings, these cells seriously perform in the most demanding applications, like electric ducted fans and 3D helicopters. eXtreme Series cells are available in 3s, 4s, and 5s packs, all with a balance connector and 3C charge rates. A few special 2s or 2p packs are available, too.
Packs with higher capacities than the above cells are made by combining 2 or more cells in parallel.
