Smart Tips

Please use either 25.9V Li-Ion smart charger below.

For fastest charging (2.1hrs), You may use 15.0A Smart Li-ion battery charger. (Must change charge terminal to 1.9" x 1.5" x 0.6" Standard Andersen connector)
For fast charging (5.25 hrs) , You may use 6.0A Smart Li-ion battery charger + the connector adaptor
You may use 3.0A Smart Li-ion battery charger to fast charge with 10.5 hrs charge time.
You may use Smart Charger (2.8A, CE listed, UL approved) for 25.9V Li-ion/Polymer Rechargeable Battery Pack with 11.25 hrs charge time

Don't combine charge terminal for charging at one time.
If you connect two of these modules in parallel, you can build a 25.9V 42 Ah Battery pack with a 80 Amp discharge rate with suitable wiring.

Must charge each module seperately, please don't combine charge at a time.
