14S 52V14.5AH, 52V16AH, 52V7.5AH, 52V21AH, or 52V19AH E-bike downtube battery with the Jumbo shark case(Polly DP-6, max hold 70pcs 18650 cells, new Jumboshark case, max 91pcs 18650 cells) ; Larger capacity will be available with this battery case; the larger capacity the battery has, the longer distance you can ride with your ebike each time after fully charging.

The 18650 cell prices keep increasing, therefore we are going to introduce 21700 for our packs. The case for the 21700 cells are DP-4C or DP-5C, the mounting for these two case are different with DP-6 or DP-9, please note.

If you prefer to view the battery status via mobile, we can build the battery with the smart BMS, and you can via the battery status via the bluetooth app from the cell phone.

The smart BMS is larger in dimension, therefore only the largest case DP-9(368 x 140 x 90mm) or DP-5C(368*95*125mm) would fit.

If your e- bike is 48V750W or 48V1000W, then this battery will enable your bike runs faster and powerful. If your kit is with BBSHD, we recommend you to use a 52V battery in stead of 48V. This battery has an ON/OFF switch and battery capacity LED. 

Regarding to currently BBSHD 07H error code, If you are going to use this battery for Bafang BBS kits, please inform us, we will set the correct voltage for you before shipment so that your battery can work for the kit.
