Buyer FAQ
Charger Selection & Ordering Questions
The questions importers, distributors and fleet buyers ask us most often about voltage, current, BIS registration and ordering. If your case is not covered, send the battery pack specification and we will answer it directly.
01How do I choose between a 48V, 60V and 72V charger?
Match the charger to the nominal voltage printed on the battery pack, not to the vehicle model name. A 48V pack needs a 48V charger, a 60V pack needs 60V, and so on. The charger output rises above nominal during the constant-voltage stage, which is normal. If your pack label shows a range such as 60V/72V, tell us the exact pack specification and we will confirm the matching model.
02What output current do I need for my battery capacity?
As a starting point, flooded and AGM lead-acid packs are usually charged at roughly 0.1C to 0.15C of capacity, so a 40Ah pack matches a 4A to 6A charger. Lithium packs must follow the charge current specified by the battery manufacturer or BMS. Our range covers 2A to 35A across models, and each product page lists its current band.
03Are your chargers BIS registered for the Indian market?
Our 48V, 60V and 72V chargers are supplied against BIS CRS registration R-41281980 for the listed models. Registration status and model coverage are updated by BIS from time to time, so please ask our sales team for the current certificate copy and the covered model list before you finalise an order or a tender document.
04Which test reports can you provide for CE and other markets?
We hold CE-EMC (ZRC2110061ZG-EMC-C1) and CE-LVD (ZRC2110061ZG-LVD-C1) reports, and RCM compliance documents can be shared for Australian buyers. Full certificate scans are available on request and are also summarised on our certification page.
05Can one charger handle both lithium and lead-acid batteries?
No. Lithium and lead-acid packs need different charge profiles, so the two are separate product lines on the same platform. Tell us which chemistry you sell most and we will quote the matching series, or both if you distribute for mixed fleets.
06Do you have waterproof chargers for outdoor use?
Yes. The IP67 series is built for rain, dust and wash-down environments, and the waterproof digital display series adds a sealed readout for voltage and current. Both are listed under the waterproof category with their IP rating and current band.
07Can the AC plug and output connector match my market?
Yes. AC plugs, output connectors, cable length, housing colour, nameplate and packaging can be configured for the destination market, including Indian, EU and UK plug types. Share your sample or drawing and we will confirm feasibility with the quotation.
08What is the MOQ and do you support OEM orders?
MOQ is quoted per model and per configuration, so it depends on the charger you choose and the customisation level. OEM and ODM orders are supported, covering housing, cable, plug, label and packaging. Send the model list and target quantity for a concrete quotation.
09How long does production and delivery take?
Lead time is confirmed per order because it depends on model, quantity and customisation. Sample orders and stock models move faster than fully customised bulk orders. Once you confirm the model list and quantity, our sales team will put a schedule in the quotation, and shipping is arranged by sea or air according to your preference.
10How do I get a price and a specification sheet?
Send the model or the battery pack specification through the inquiry form, WhatsApp or email, and include destination country and target quantity so the quotation is accurate. We reply with price, specification sheet and the available certificate copies.
Still deciding which model fits?
Send the battery pack voltage, capacity and chemistry — we reply with a matching charger model and its specification sheet.
