Today, we have all orders paid in lockdowns shipped away, and some of riders already got the battery and did some biking test. Thank you for all your updates and patience. Now will push all new orders shipped ASAP. There are still some Dorado 505L 48V 25Ah and the short Dorado 440L 48V 20Ah...

Will absolutely get back and update when the EEL PRO is available for 21700 options someday, not now.

Hi, it is short Dorado 440L, battery length about 15.5inch/390mm, that is used on Surface 604 2022 Werk, Shred,Rook, Colt,and Boar. Surface604 provides the Reention Dorado plus 440L 48V 14Ah and their own proprietary design of 48V 20Ah. We have the Reention Dorado 21700 440L case for same 48V...

The 25Ah looks perfectly fit on the shengmilo mx03. Thanks for sharing us so many pics and the real testing experience.

Thank you for sharing us the one-year review and we are looking forward to the two-year testing and tests about 52V 20Ah Dorado battery on 48V motor and controller system.

Thanks for your inquiry, would you mind sending me an email to confirm more details. [email protected]

It is 30amp BMS that used for Dorado 25Ah, so 20A or max 25A controller is suggested. The low discharging current will prolong the battery lifetime.

Lockdown in Shanghai will be totally lifted on tomorrow, 1st June. Will push all paid orders shipment as fast as we can. Appreciate all your continued great support.

The ebike manufacturer must know who the battery case designer is and offer the replacements.

It shall be SYR002 Mustang used on Aventon Level.

May I know the ebike model? I haven't seen this either, seems not from Reention, or Shanshan or SYR. There are more and more patented cases with proprietary ports.

This is how dual battery converter works explained by Biktrix. But I haven't figured it out clear myself. 😅 It sounds like the converter smartly keeps switching between the two batteries, makes the two batteries dynamically in same level voltage till the cut off voltage. If so, there is always...

Thanks for sharing. It is a mechanical switch to let the battery discharge from one to another as you want. So no concern to maintain the two batteries in same voltage level as the video explains.

Exactly, even the charger manufacturer develop their own proprietary connector. The worst is that some ebike manufacturer develop their own patented battery case to avoid a 3rd party battery option.

Yes, that is suggested by our engineers unless you can make sure the two batteries are totally same and new, and to charge both batteres to same voltage to use everytime. And pls also check with the converter module manufacturer to see what is best way to use.

Thank you @AHicks for recommending us always. As @tomjasz mentioned, the lockdown hasn't been lifted yet, but things are getting much better now. The secondary battery shall be Reention Polly DP-2170-5,368x95x125mm, max available for 52V 15Ah by Samsung 21700 cells as Rize offers. DP-9...

The battery is indeed switched from Reention Rhino IR-5 to IR-7 version on 700 series. IR-5, 363x74x99m, 52pcs 18650, 48V 14Ah max. IR-7, 441x74x99mm, 70pcs 18650 or 42pcs 21700, 48V/52V 17.5Ah by 18650, or 48V/52V15Ah by 21700. IR-21700, 441x80x108mm, 60pcs 21700, 48V/52V 20Ah max by 21700...

Hi, which dual battery converter module you chose? As I know, there are two kinds of module, one for discharging from A to B battery, and another for discharging from both batteries in the same time. Even for the latter, it is suggested to choose a second battery with on/off switch to still let...

Hi, may I know your ebike model? It looks same as NCM Moscow. I will invite @Bitmugger to share the testing result, who owns a NCM Moscow and he will test the Dorado 52V 20Ah after the lockdown lifted here.

NCM Milano uses the same Dorado 18inch battery. @Eucrider https://www.leoncycle.co.uk/NCM-Milano-Trekking-E-Bike
