Jimbothejetsetter 4 Posted April 3, 2020 Hi, Please can anyone advise me as I don’t have much knowledge on lipo batteries. I would like to buy a 2s battery for a 7800kv brushless motor and 18a Esc combo. How do I know what to buy? Volts, C rating, Amps? Which brands are good? Any advice would be much appreciated. thanks Jimbo Share this post Link to post Share on other sites

Problemchild 2149 Posted April 3, 2020 Size of battery will be your first issue then how to charge it (mine field and not like Nimh at all. then you need to know what your speed controller will handle I buy floureon as they are cheap and pretty rugged FLOUREON 3S Lipo Battery 25C 11.1V 2200mAh XT60 Plug RC Drone Battery Pack for RC Car Truck RC Boat Traxxas Slash Flame Kyosho Racing Truck (2pack) https://www.amazon.co.uk/dp/B00N79TEBC/ref=cm_sw_r_cp_api_i_MV7HEbDW120M1 I am rubbish at maintaining them (ie when not in use discharge to storage voltage etc) i am using with a goolRC brushless combo ebay special in my TT02b and its beyond fast - like 40mph JJ Share this post Link to post Share on other sites
Problemchild 2149 Posted April 3, 2020 P.s. do some research on LiPo anyway like balance charging (you need to get a charger AND a power supply for the charger), storage charges and where to store them, maintaining them, disposal, LiPo monitors (you can’t discharge them till flat like a normal battery) etc the speed you get is worth a few headaches though JJ Share this post Link to post Share on other sites
Wooders28 4723 Posted April 4, 2020 Before leaping into the world of lipos, have a read through :- https://rogershobbycenter.com/lipoguide/ Also, if it's a 540 size motor, a 7800kv will need closer to a 120A esc. Share this post Link to post Share on other sites
