For product compatibility, charging, installation or troubleshooting questions, email blwnykj@gmail.com or use our contact form.

Before You Buy

Browse batteries by system voltage. If you are unsure which model fits, open a compatibility inquiry and include your equipment make, model, controller details, battery space and connector photos.

Help With an Existing Battery

Open a technical support request with the following information:

Purchase channel: this website, Amazon or another seller
Order number or proof of purchase
Product model and serial number, if available
Date received
Charger label and connector details
A description of the issue and relevant photos or videos

Charging and Protection

Use the charger specified for your exact battery model. Protection thresholds and reset procedures vary by model; follow the supplied manual and contact support before attempting a reset or recovery charge. Do not apply a single voltage threshold to every battery model.

Model-Specific Instructions

If you need a manual or installation instructions, email us with your product model. Battery compatibility depends on voltage, controller requirements, charger, connector polarity and installation space.
