January 19, 20188 yr Can anyone help with the info of the below batteries, and which one to go for? I dont really want it for long distances but for more, getting me up hills...

January 19, 20188 yr GA 17.5 AH Ask for charger upgrade at least 3A better 5a How do you get 17.5 Ah from a GA? 5P = 16.75 and 6P = 20.1... 5 x 10 A = 50 A discharge 6 x 10 A = 60 A discharge The 30Q batteries are more honest in their description and 4P also delivers 60 A discharge. That is why I put them in first place.
January 19, 20188 yr Hailong-3 48V 11.6Ah Lithium Ion Frame Battery 29E Samsung Cells + 2A Li Ion Charger I don't know anything about batteries so take my opinion with a grain of salt but I bought this exact battery from Eclipsebikes and it lasts 50km+ while using pedal assist. My display said it had 60% battery left but that was probably wrong. The mount absoloutly sucked though and I had to drill holes in the metal plate to make it line up with my bottle holder.
January 19, 20188 yr How do you get 17.5 Ah from a GA? I think because most sellers rate them at 3500mA capacity
January 19, 20188 yr Can anyone help with the info of the below batteries, and which one to go for? I dont really want it for long distances but for more, getting me up hills... Thanks, Ali It would help if we knew the size of your motor and controller. there is no point paying for high capacity/discharge cells if you dont want range and are running a low power system.
January 19, 20188 yr I think because most sellers rate them at 3500mA capacity Well then that is false advertising and there are laws against that! GA cells have a nominative 3350 mAh capacity from the manufacturer. You may get some more in real life then again you may get a little less...

Those are 8.25 Amp discharge cells so if you have a 48v motor with a 20 A controller you are over stressing them, I am not surprised you get that range.

January 19, 20188 yr Author the motor that I have got is... Bafang BBS02B 48V 750W Mid Drive Motor Kit - LCD Display: C965
January 19, 20188 yr the motor that I have got is... Bafang BBS02B 48V 750W Mid Drive Motor Kit - LCD Display: C965 Ok, so as anotherkiwi suggested, the 30Q is prob your best bet as those cells will be under the least stress and should therefor last well.
January 19, 20188 yr Author Ok, so as anotherkiwi suggested, the 30Q is prob your best bet as those cells will be under the least stress and should therefor last well. So I deffinately don't go for the WHALE 48V 17.5AH LITHIUM ION FRAME BATTERY GA SANYO CELLS? Go for the 48V 12AH LITHIUM ION FRAME BATTERY 30Q SAMSUNG CELLS? Even though there is 5.5 difference in the amps? Don't go for the bigger amp?
January 19, 20188 yr 30Q cells are the best of the bunch. GA cells are good initially then they apparently loose capacity, rated for 10a @ 60c temp but over heat at this temp approaching 8a draw so spec is a bit ambitious. 29E better in 6p strings.
January 20, 20188 yr Check out the Panasonic/Sanyo GA cells yourself with data sheets. You are getting strange info/hearsay on this thread. You won't find better cells at this moment in time for what you want. Don't forget to see if they will upgrade the charger from 2A too.

For that you need high discharge IIRC so the 30Q is largely superior in that respect with a 25A controller...

You won't find better cells at this moment in time for what you want. Don't forget to see if they will upgrade the charger from 2A too. Data sheets put out by companies are mainly there to put there technology above the competitors, you have to take their claims with a pinch of salt. Micah Toll of ebike school.com recently did a temp test with GA's on Endless Sphere and with the 8a load the cells got up to and over 62c above the recommended 60c for 10a draw that is claimed. Next up he plans to do the same with other top cells like 30Q & MJ1.
February 1, 20188 yr Any experience with / views on the Samsung 35E cells? Apparently a low - medium 8a rated cell with quite good mah results, probably best in 6P or more.
February 1, 20188 yr 12AH 30Q cells is the lightest battery. It can give all the current you need. you should get a range of between 20 and 50 miles depending on how much power you use.
February 2, 20188 yr Thanks both. I want maximum range for a long trip. I’m planning on doing LEJOG so some days of 90 miles. Plan to use the Xiongda YTW-06 with max 13a controller so not huge power draw. Also want to keep weight to minimum. Thinking of 10SP5 - 17.2ah pack from ENERpower.
February 2, 20188 yr 90 miles will still be a tall order from 17.2 ah on a normal bike unless you can do a lot of unpowered riding on flat routes or use very low assist quite a bit. I managed 93 miles with a 15a controller but had 24ah of cheap Samsung cells, at the time the cells were brand new. I have an inkling to try the 35E but it would be in 6 or 7P configuration as a soft cell build. Edited February 2, 20188 yr by Nealh
February 2, 20188 yr https://www.nkon.nl/rechargeable/other/sanyo-ncr20700b-lithium-battery.html When I get a spot welder I will make a couple of 3P12S batteries from those and use either 1 on the upright or 2 in parallel on the trike so either 12.15 Ah or 24.3 Ah @ 44.4v. Equivalent to 70 to 143 km range locally at today's strength levels and about 185 km on the flat.
