RadMission 1 Standard 14 Ah battery compatibility?

Is it possible to use the 48V, 14 Ah (672 Wh) Standard Rad Battery Pack with the RadMission 1? The Rad Power Bikes website indicates that the RadMission 1 is only compatible with the 48V, 10.5 Ah (504 Wh) battery pack. I've read online that the Standard 14 Ah Battery Pack will work on the RadMission 1, but I would not want to cause any damage to the components if the smaller capacity 10.5 Ah pack is the only battery that should be used.

The Standard pack is out of stock on the Rad Power Bikes website, so I may purchase the 10.5 Ah battery to double my range, but I can wait until the 14 Ah battery becomes available if it can be used with the RadMission 1 safely. Any information, feedback, or comments will be greatly appreciated.

Okay so, I found the battery in question.


"The RadMission 1 Battery Pack is 48V, 10.5 Ah (504 Wh), and works exclusively with the RadMission 1 electric metro bike. It is not compatible with other Rad Power Bikes models. Do not use the RadMission 1 Battery Pack on other Rad Power Bikes models."

Okay, I get this part, because RadMission battery is powered by Samsung 35E, and it is 13S3P
Compare to 13S4P, which is still powered by Samsung 35E, I guess the load exposed to each cell would be higher on 13S3P.

I can see why 750W bikes like RadRover should not be using 13S3P because it could put more stress on the cell.

However, what I don't understand is this:
"The Standard Battery Pack is 48V, 14 Ah (672 Wh), and compatible with all 2018 and newer model ebikes except the RadMission 1 and RadRover 6 Plus."

What's the problem using 13S4P on RadMission? Wouldn't that be completely fine?

Thats typical for Rad. Contact Rad only if you have warranty issue or absolutely want to buy stock parts from them. Otherwise you got zero usefull information from that source 🙂

Answers to your question is Yes, you can use 14Ah stock Rad battery on Mission.

I would recommend you going aftermarket batteries if you're looking for high capacity pack.
There are reputable sellers out there and frankly you will save money.

I wonder why Rad would want to say that 14ah won't work on the RadMission though?

If doubling your range is your concern, you should just contact Jenny and purchase Reention Polly, 48V 24.5Ah battery from Jenny.

You will just have to go through mild inconvenience of switching battery cradle, purchasing connector adapter (or solder right connector), etc.
But you will gain substantial amount of range.

Jenny has been selling batteries to EBR members and people are happy with her service and price.

Alternatively, EM3ev is a good option.

Rad is saying don't use the lower capacity battery on a Rad bike with a 15A controller / 750W motor , presumably because of potential current draw/discharge rate.

Doesn't mean the inverse is true, a larger capacity 48V battery will be fine on a Mission.

Even in the low capacity battery & high capacity controller/motor scenario, wouldn't BMS protect the battery for over-discharging?
You probably won't get the best our of the controller/motor if you use weak battery though.

A good BMS might do that, normally they just allow the battery to operate within a certain voltage range.

Kind of like plugging a 20A appliance into a 15A outlet, might work for a while but won't do the outlet/ wiring and fuse/ breaker any good.
