Expected shipment to leave China by _____. 

Air transit will usually take around 10 days to travel from China, pass through customs, get on a truck and be delivered to Austin.  Individual orders going directly to different cities are sometimes a little faster than 10 days.  So expect delivery at the address specified on the web site order is on or around...

Slow boat deliveries will leave around the same time, but will be going to a port transiting across the surface of the ocean and arriving at a US port.  Current transit time is approx ____ days.  Currently it takes ____ days to unload a container ship this could increase as we get closer to the holiday season.  Then there is customs and overland transportation to Austin Texas.  Expected total transit time is approximately ____ days.  It may be faster, it may be slower.  Usually it’s on the faster side of things.  That puts the slow boat arrival date ____ 2022

We expect that we will sell out of batteries before they arrive in Austin.  So if you want one, please put in your order soon before they sell out. 

There are too many unaddressable variables right now to be 100% certain of any items or circumstances that may arrive through this 90-120 process.  

Please know we will handle everything within our power to keep your interests a priority for a prompt delivery. 

UPDATE:  Early Bird orders for Spring 2022: 
(Dec 20th  - Dec 31, 2021)

* We've recently been notified via our suppliers that pricing is anticipated to increase at the start of Jan 1, 2022.  Prices increased on our 2021 order for both product and ship. 

2 delivery options are available via Air or Boat.

+ In store purchases have now been added to our online platform as a 3rd purchase option for non-early bird buyers.

SLOW BOAT, Early-Bird local pick up in Austin, Texas:  $995.  Arrival time 75 to 90 days.

In store purchase in Austin, Texas:  $1150.  * While supplies last *  

DIRECT AIR SHIPMENT TO YOUR ADDRESS:  $1300.  Arrival time 40-50 days.

Why more expensive and so slow? Covid-19 and general pandemic hardships have cause an overwhelming shortage of raw materials, thus creating a bottle neck for imported goods.  Supply chains are broken and labor forces still prove to be limited and low.  Over demand + under supply = price increases + ship delays

In the future we hope to maintain a steadier inventory to enable faster pick up/delivery to customers.    

PLEASE NOTE:  All measurements are approximate, as size variation can occur in the production process. 

Replacement BMS modules are additionally available for order on site. (Very few have ever required replacement) 


Big bikes need big batteries.  Long days require long run times.  Professional pedicab drivers deserve professional grade products.

Precision pedicab is striving to offer the best price available for a high quality battery and charger packaged in a way that works for pedicabs.  The steel case encloses the battery to protect it from external damage, and meet the charging requirements of the city of Austin.  While is is extremely unlikely for a LiFePo4 to catch fire, the steel case adds an extra layer of protection to better contain a fire and reduce property damage. 

USE CAUTION WHILE CHARGING!!!  KEEP FLAMMABLE MATERIALS AWAY WHILE BATTERY IS CHARGING.  Monitor batteries while Charging.  Educate yourself in safe battery practices that extend your battery life.  

The price includes a high quality charger that also meets the city of Austin charging requirements.

While these are not as compact and power dense as some e-bike batteries, they are far less likely to catch fire and cause property damage than other lithium chemistries.   LiFePo4 batteries also have much longer service lives than lithium ion batteries, getting up to 2000 charge cycles if treated properly.

With pedicabs, getting long run times, longer service lives and good power delivery at a reasonable price is a winning combination.  These batteries offer a great value for the work we do and the more generous space and weight budgets that pedicabs have.

These batteries have proven to be some of the most durable and best available in this amp hour capacity and price range. 

Batteries have a 30 day warranty for material or manufacturing defect.  In that 30 day period we will at our description refund, repair, or replace with a similar battery.  This is handled on a case by case basis depending on circumstances presented.  Warranty does not cover mishandling (dropping), short circuiting (crossing wires), modification, intentional or unintentional misuse.      

Important note: due to hazardous materials shipping restrictions for lithium batteries, once the batteries arrive at the 1710 East second street Austin, Texas 78702 location, we cannot ship them via common carriers such as UPS, USPS, FEDEX etc.  We have been able to transport batteries via LTL freight, U-Ship carriers, traveling pedicabbers etc.  If shipping from the Austin shop is required,  shipping costs will be charged to customer when cost of shipping is determined.
