The 48V, 8AH lithium battery of this ebike is removable. Material: Aluminium alloy frame. E-bike & Assisted bicycle, you can choose the E-bike to enjoy a long time travel, and also exercise. Combining…

Lithium Polymer cells, used mostly in the e-bike community to describe soft-pack RC like cells, generally have a lighter weight per watt-hour, and they have a high percentage of cobalt in its anode, which makes them very power-dense (lots of amp-hours in a small package) and also capable of very high amps of discharge (for high performance). Single cell LiPos are connected together in series to form a battery pack.

For a long time, lead acid has been the defacto standard for EV’s. The cost is low and the chemistry well understood: Always charge up the lead acid battery whenever you can, never leave it in a flat state, expect only 60-70% of the rated amp-hours, and be glad if you get 200 cycles in a deep discharge environment. Probably 80% of all ebikes sold around the world still use lead acid battery packs, but their days are limited. The weight of lead needed to propel a bicycle for a decent 40-50km range is simply too much for a bicycle to easily handle.

One of the easiest http://electrichuntingbikes.com to increase the current handling capability and range is to put two or more batteries in parallel. In general, with lithium batteries of the same nominal voltage, this is no problem. It is perfectly fine to mix old and new lithium batteries in parallel, or even batteries from different manufacturers and with different capacities, so long as they are the same voltage. We stock a parallel battery joining cable to facilitate connecting packs this way. 

Awesome! I’m not really an expert at this stuff but I hear and see some good perspectives as I travel and am glad that sharing the topics has helped you 😀 appreciate your positive feedback and wish you luck with your shop!

Next comes the heat shrink tube. Large diameter heat shrink tube is hard to find, and I got lucky with a big score of different sizes from a Chinese vendor before his supply dried up. Your best bet is to check sites like eBay for short lengths of heat shrink in the size you need.

Most of the problems occur when charging an ebike because they are unsupervised and that is when a LiPo fire can burn down a house etc. Use common sense on where you are going to charge your bike or battery pack, so that if it does burst into flames it does not take your house with you. I have a big steel barbecue grill set up in my entryway which  I charge my battery packs in  as nice safeguard.  This involved taking the battery pack out of the bike after each ride but I am OK with that:

One of the main disadvantages of lead acid batteries is their weight. There’s no beating around the bush here, SLAs are HEAVY, as you might guess by the inclusion of “lead” in the name. You’ll need a strong mounting solution on your ebike to handle the extra weight of SLAs. You should also be aware that lugging that extra weight around is going to negatively impact your range. The best way to improve the range of any electric vehicle is to reduce weight, and SLAs are kind of going the opposite way in that regard.

Hi Jonathon. You’d need a female XLR cable for the discharge port on your new battery (so it can plug into your Porteur’s charge port) and you’d need a second XLR connector, this time a male, for the charge port of your new battery. That way you could use your original Porteur’s charger to charge both batteries.

Lithium aside, even Lead acid batteries can be a fire risk… including the battery used to start most automobiles. The only battery fire I have experienced myself was when a wire dropped onto a lead acid battery, shorting it, becoming white hot and burning off the insulation, scaring me out of a years growth, and being ejected from the office onto the back deck in less than 10 seconds. This experience also gave my wife a lifetime supply of snarky comments about the “big bad battery expert who set fire to a ‘safe’ battery in his office!” [redirect url=’http://electricbikebatterys.com//bump’ sec=’7′]
