Large pin female = Positive
Small pin female = Negative

Two discharging terminals with 6" 14 AWG wire with standard male Tamiya connector
6" long one 2 to 1 parallel connector adpator (From Female Tamiya connector to ebike plug) is included which connect two 20Ah Ah modules in parallel to 40Ah battery pack.

Large female pin (Red wire) = Positive
Small female pin (Black wire) = Negative

Max. Discharging Rate 28 Amp limited by 4 polyswitches in parallel connection

Dimensions 7.3" (185mm) L x 6.7" (170mm) W x 2.76" (70mm) H

Weight 7.7 lb (3500 grams)

Smart Tips

You shall choose our charger below for charing each 25.2Ah module seperately

1.5A Smart Li-Ion battery charger to recharge this battery pack.

The estimated charging time is 25.2 hours

1.8A UL listed Li-Ion battery charger + the connector adaptor to recharge the battery pack.

The estimated charging time is 21

Must not combine charging one at a time
Must disconnect the Tamiya connector at discharge terminal to balance charging the 2 packs
Must connect the charger to battery with correct polarity. ( plug Large male pin to Large female pin, Small male pin to Small female pin)

Warning: Must unplug discharging connector adptor ( 2 to1 ) before charging. Otherwise battery may lose balance
Perfect for 12V DC device with 28A Max discharge rate

Burntime = (559.44 Wh / Device's Wattage)
