I added the 20ah Dorado with Samsung cells to my MacGyvered dual battery setup. Wow, this battery packs a punch. My existing battery was 12.5ah, so this one kicks the power up to 32.5ah. What I did not expect was that my bike's performance would improve. I am getting 2-3 km/h gains in each of the 5 assist levels, and there is noticeable improvement in torque. Maybe this is a stealth 52v battery?

The Bixktrix sales staff was excellent in helping me with my purchase. The battery was shipped a few days after it was ordered, and it arrived by Purolator a day after it was shipped. I got a great deal due to a summer sale (less than half price). Shipping was $60, but this was partially offset by a $27 welcome coupon I found online. The battery was securely packed in a larger box, surrounded by high density packing foam.

The fan-equipped charger puts out 3 amps, and charged my battery fully in about 5 hours. Initially the light on the charger was flashing red and green. I was worried that something was wrong, but the Biktrix website reassured me that this was just the BMS balancing the cells. The flashing lasted for a few minutes then the battery charged normally. The charger got pretty warm, even with the internal fan, but I suppose that is to be expected with the higher amperage.

The 20ah battery is wider than a standard Dorado battery, and quite a bit heavier, but will fit on any bike that takes a standard Dorado battery.

So far I am extremely happy with this purchase. On my dual battery setup I have ridden 30 km and my display still shows 10/10 bars. I anticipate at least 150km range, and with the gain in speed, I am a happy camper.

Very reliable battery.

Happy happy happy

Needed a new battery and it was delivered fast and speedy, the ports and covers are a significant upgrade from my previous battery. Needs a little more of a push when inserting. But looks sleek.

the second battery work's great on my classic bike it's the I got thru R&d Powersports in Palmerton Pa.
