How to Choose Zeee 2S and 3S LiPo Packs for RC Trucks
Choose a Zeee 2S or 3S pack by tray size first, then case type and discharge rate. Shorty packs measure 73 mm and 75 mm long and fit tight trays. Hard-case packs measure 138 mm long and add knock protection. Match voltage, size, and plug to your car or truck before you buy.

What fits a tight battery tray?
A shorty pack fits a tight tray when a full-length pack will not, so measure the tray before you order.
The 2S shorty measures 73 x 34 x 18.5 mm and weighs 98 g.
The 3S shorty measures 75 x 34 x 26.5 mm and weighs 137 g.
Both shorty packs use a soft case with 14AWG leads, an XT60 discharge plug, and a JST-XH balance plug.
The shorty size suits RC cars with small trays, and it also fits airplanes, boats, and trucks where the size matches.
When does a hard case earn its size?
A hard case earns its size when the pack takes knocks on the track and in the pit bag.
Both hard-case packs measure 138 mm long, with the 2S pack at 250 g and the 3S pack at 380 g.
Both hard-case packs hold 5200mAh, so they run longer than the 2200mAh shorty packs on the same model.
Both use 12AWG leads with an XT60 plug and a JST-XH balance plug, and both charge at 0.5 to 1C.
What does 50C versus 80C change?
The C rating times the capacity gives the rated continuous current, so the math is direct.
A 50C rating on a 2.2 Ah pack gives 110 A, and on a 5.2 Ah pack it gives 260 A.
An 80C rating on a 5.2 Ah pack gives 416 A, which suits models that pull hard under load.
Charge at 1C or under: 2.2 A for a 2200mAh pack and 5.2 A for a 5200mAh pack.
