The BA900 is a universal battery testing device. Read here to see what advantages it offers.
- Make sure a battery is charged to 100% before test. Now others will know the test result is reliable.
- Test with real-life load on the battery. A low-current test may not show problems.
- Connect 2 batteries for automatic testing (Charge — Test — Re-charge).

Electric Vehicle (EV) batteries can determine their capacity accurate enough to rely on for warranty purposes. EV’s have a built-in battery analyzer that also reads and interprets BMS data, which is vital for warranty evaluation. This article explains which limitations an E-bike BMS has, how to deal with this and how to -theoretically- resolve this. Continue reading Why an E-bike BMS cannot accurately measure battery capacity
When the state of health of a battery needs to be determined, most manufacturers rely on the readout of the BMS. Although most BMS’s provided a number, it does not say how reliable it is.
The BMS state of health (SOH) value
Most battery packs have a BMS that is based on a standard IC solution. Well known suppliers are O2micro and Texas Instruments. They have documented to algorithm used to calculate the State of Health. The chips computer the FullChargeCapacity (FCC) value if a discharge from full to empty has been done. Continue reading Battery Testing v.s. BMS readout
While Lithium Nickel Cobalt Aluminum (NCA) batteries are the main stream in e-bike batteries, other technologies may take over. Battery Management Systems (BMS) are often the Achilles heel of e-bike batteries.

In 2012 a seasoned Dutch electronic design team started to design a battery analyzer, specifically for e-bikes and after extensive consultation of the e-bike industry. After extensive alpha & beta testing in 2013 by many e-bike professionals and many valuable suggestions, the final release –aimed at e-bike dealers- was introduced in February 2014 and in fall 2014 follow-up models for S-Pedelecs and higher.

Warranty conditions for e-bike batteries always include the guaranteed capacity until the end of the warranty period. Often a maximum (full-equivalent or partial) charge/discharge cycles and more and more conditions to deny warranty in case of deep discharging and/or minimum charge intervals.

E-bike (system) manufacturers now have the option to offer their dealers an economical (volume pricing as low as € 195) battery tester with specifications, exactly fitting the requirements and with optional BMS interfacing, fine-tuned to your requirements. Custom cables and OEM branding will be available. Future upgrade to standard models is possible! Continue reading Battery Condition Test introduces OEM battery tester for Pedelecs
When cells are produced, they are tested. But a small percentage has weakened when they are assembled into packs, usually months later. This may be caused by impurities in the electrolyte, resulting in shorts, which in turn cause an increase in the internal resistance.
Continue reading Recognizing weak cells in Li-ion battery packs
When a consumer considers claiming warranty on an e-bike battery, all needed is to request the dealer to accept the claim as the dealer has a legal obligation to handle this. Continue reading Why BMS Interfacing reduces e-bike battery warranty cost
For senior managers of e-bike (system) & battery manufacturers/importers
Battery Condition Test offers implementation of BMS to e-bike manufacturers or their suppliers. R & D costs are not charged when the manufacturer commits to recommend BCT’s battery analyzers to their (OEM’s) dealers, BCT considers the BMS suitable and the scale justifies this.
