~84V is about the max the Valence packs achieve.

Hi , just signed up so I a newbie. What a great forum ! Back to topic, I want to ask how the Segway knows it is a NiMH I have a Lion pack and want to modify it to Lipo (I am very familliar with Lipos) without all the feedback the segway wants . Does anyone have a pinout for the NiMH packs.
Thanks

Default replacement NiMH batteries

Hi, as I am in need of replacing my 167 original NiMH batteries and am not enthusiastic about spending a fortune., I found this post looking for info about rebuilding my packs.

I know this post is old, but hoped people still check it...

For simplicity sake, I was thinking of just replacing the current NiMH cells with new NIMH cells. I was considering using these pre built 10 cell packs...

(I can't post links as I'm a newbie)
all-battery.com/rectangularnimh12v4500mahhighdrainbatterypackwithb areleadscustomize.aspx

can anyone offer an opinion as to whether they would be a problem?

thank you,

Jason

would recommend MTO battery's rebuild pack, it's design for Segway, with proper insulation and vibration damper, also it is using much thicker nickle plates to handle high current under hill climb and steep decent.

your link with the 10 pack Ni-Mh might work but really not recommended.

also with the plastic package, the battery temperature sensor will not work properly, and will send false signal to the BMS, causing the battery to under charge and might enter emergency shut down mode during hill climb and decent.

that cable is not heavy enough to carry the current either, it will get very hot on heavy load causing the insulation to melt.

Thank you for the reply... those are the kinds of things that I worry about - obviously... I don't want battery melt-downs or Segway shut-downs when I least expect it. I don't use the Segway nearly as much as I "should" so to spend a lot on batteries is nearly unjustifiable, but a dead Segway is no use either.

That site also sells individual Cells but I figured the pre-built packs would be better than what I could attempt to "Remake." In the interest of safety, I will look at MTO.

Thank you,

Jason

Your problem is not new and the problem is explained in your last sentence.
May God bless your Main Board.

I am no battery expert, but there is a lot of communication between the segway and the battery, with most of the charging circuit in the battery itself, and mostly just the power supply in the segway.

Because of this, I do not believe you can get a LiIon battery to act like a NiMH battery. It is much more complicated than that.

Again, because of all the voltage and current sensing that goes on between the battery and the segway main boards, I do not believe you can do what you said you planned to do in your post.

If you deny the segway all the feedback it wants, as you put it, the segway will just stop operating, or may not even turn on.

Good luck. Keep reading. Talk to the people who really know, instead of the rest of us who make believe we know. There are a few names of good folks here who will come up when you read, that offer good advise, and data.

When you finally get to it, check in with segway or MTO. In the long run, or the short run, eventually you will need the support of either of those two when it comes to replacement of you batteries.

Hi Jason,

Just a thought. Talk to some Segway dealers about used batteries. I personally know of some trade-ins that still took a charge but didn't get the distance needed. Better than buying new or blowing up your Segway!

Good luck!
