My vote is get both batteries and carry the second one in a bar bag if possible.

I'm getting forty to fifty miles on mostly level 3 and 4.
Really? How do they do that? (Nuts in Minnesota).they'll make it better than new for a lot less.

Nice bike!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!
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......!
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.
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? ThanksI 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.

We ordered a 2nd Giant 500 in the Spring and it arrived last week!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
Thanks for the quick response. Did you order through your dealer? I need my second by June but need to get the order place it sounds like. JimWe ordered a 2nd Giant 500 in the Spring and it arrived last week!
Yes from the Giant store.Thanks for the quick response. Did you order through your dealer? I need my second by June but need to get the order place it sounds like. Jim
That is rubbishWow, 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.
Thanks. And you got the 500 and it fit just the same as the 400 that came with your 2020 Explorer? i have assumed you are in the States not Canada?Yes from the Giant store.
Get yourself a decent e-bike fis
