Upgrading to a larger battery. Trade in the new existing battery for a credit or just buy the new one and have two batteries?

If it's the 400wh Yamaha-Giant-Haibike battery, the potential is there to bring it up to the better long range 500wh standard. In the PW drive I have on my Haibike, a 400 battery will get you an estimated 43 miles in the high power setting; 53 with the 500. And I can tell you in optimal conditions: light gradients, no stiff headwind, those estimates by Yamaha are spot on.

After ebiking a good many miles on my original Haibike 400wh on the Full FatSix, I wanted to extend the range of my miles, but not by powering down to the lower power levels where I am basically powering a near 65 pound tank! So over the summer of 2019, I wound up investing in two brand new 500wh batteries, to go along with the original 400wh the bike came with.

Take that, Riese and Muller and your 1000wh dual battery system! :D

The Ortlieb EMate panniers are designed to hold the Yamaha battery like a pea in a pod. In the photo below, I carried all three batteries on my bike, on a 100% asphalt ride from the western side of NJ, to the east and the Atlantic Ocean, and back home. All done in the High Power setting. When one battery got down to about 25% power remaining, I simply swapped it out for a fresh battery.

A dual battery and more Ebike opens up the potential to do over 100 miles, if you are so inclined to do that kind of day touring and mileage. Weight means nothing when riding in the upper power levels, from personal experience. Fwiw, my ride was near 100 miles when all was said and done, not bad on a full suspension fat tired bike!

This kind of potential awaits the OP of this thread!

Hmmm, Ravi pointed out in another thread that a company in Germany has made a 750wh battery to fit the Yamaha drive system.....thinking......thinking......!

Nice bike!
 
OP, which bike shop allows you to upgrade the battery on the Giant when you purchase. I have been thinking about a 2020 Giant ebike, but the 375 wh battery is a turn off. If I could pay extra and get the 500 wh battery and a credit for the stock battery I'm more interested.
 
I haven't seen this, so I thought I'd suggest it. It strikes me that 2 batteries with 2 chargers might make more sense than 3 batteries with one charger. Unless it's a Grin Satiator or some very high end charger, chargers are both cheaper and lighter than batteries. I happen to have a Bosch bike, so that's especially true. Assuming that you're willing to stop for a bit mid ride to charge rather than trying to go as far as you can go without recharging, the advantage of using two chargers with two batteries would be that you get twice the charge in the same amount of time. If full recharge time is four hours, i can get that in two hours with the disadvantage of having to change batteries a little more often. You'd also be saving about 5 pounds.

Taking that concept one step further, it would be nice to have a bike with a battery that is 600 to 700 watt hours and a Grin Satiator. You would save even more weight and I think you could charge up to 80% capacity easily in 2 hours with a Satiator. Of course a Satiator is expensive so that's the trade-off. But if you ride long distances a lot, I think it would be worth it.
 
Another negative for me regarding some makers, over priced featureless chargers. I use Satiators and now my shop owner sells them. i use Chinesium chargers for backup. $10.

I will be purchasing a new 2020 Giant Explore E+4 that comes with a Giant EnergyPak 400, 36V 11.3Ah Rechargeable Lithium-Ion. I want to upgrade to the 500 watt battery during the purchase. I was told I had two choices. (1) Buy a new 500 watt battery for $550 and keep the existing battery. (2) Trade in the new 400 watt battery towards the 500 watt and receive a $250 credit.

Although a new battery (as such) for $250 seems like a good deal, my question is (especially during the winter months) will I potentially shorten the life of one or both batteries from lack of use? So Questions are:

1. Trade the 400 watt battery in for the 500 watt and save $250 on the price?
2. Spend the $550 on the new 500 watt battery, have two batteries, and rotate them for different bike rides?
3. Will having two batteries extend the life of both batteries because of fewer charge cycles or will they both die at about the same expected time as one?

For now I may only ride the bike 2 or 3 times a month depending on cold and snow conditions until spring.

Larry what did you end up doing? I am trying to buy a second 400 for my 2020 Explore or a 500 and dealer is having a hard time finding either from Giant. Do you know of any other source that has them in stock? Thanks
 
Wow, 4-500wh in 2021. Your newbies don't want to learn , no matter how much teachings we try to do.

Get a proper ebke with a 48v system and min. 600wh pack. 672wh best : 48x14ah. Or 700wh.

Your weight may not be 165lb ,if it's 250lb a 500wh pack is obsolete. Add 35-40lb of gear or a fat Turkey , 15mph wind ,and you will regret no going for a bigger pack.

Then when you do want to buy a proper e bike and want to sell this 36 V one with the decreased wh (maybe 400wh ,20%loss nobody's going to buy that ebike. They Are already working on the 4860 cells and with those the battery pack is going to be 2x lighter for same wh.

Start with high WH,Then if you don't chicken out you can also buy the Satiator and charge @6-7AH. In 20min. 100wh.

Fyi- the shop in Ca (fth power) does not work anylonger on bms packs . Only e3mv can upgrade it.But it' s 500$ to upgrade or renew a 500wh pack .Fth power WAS charging a LOT less, i think it was 250-275$ 9monts ago with one way paid shipping.

That is rubbish
 
@Ebiker01: It was many times I asked you to not express uninformed disinformation.

If you owned at least one Giant e-bike with integrated EnergyPak Smart battery, you would even not mention "48 V" or Ah. Giant e-bikes belong to completely different world that you seem not to understand yet. Get yourself a decent e-bike first, talk to "newbies" next.

Sorry for being personal. I should have "ignored" you long time ago.

@Jim Conboy: I am almost completely sure EnergyPak Smart batteries are interchangeable. Could you check the label on your battery? Does it read "EnergyPak Smart"?
 
Cmon stop trolling, caling names and show your gealousy . You either ahdfallen on yor ebke again or your wife sold your Specialized ??
36volts is not 48volts .

Fyi- BH is VASTLY superior to your old Vado. 110 years of superiority.
Use you time to learn about it not type same anecdotes. You should also sleep -is 4am where you are .
