369DRONE LAVA II 1S Battery 320mAh (5PCS) Review

This listing is the 320mAh size of the LAVA II 1S battery from BETAFPV, titled as a pack of 5PCS and priced at $24 as a single option. The listing states a 95C discharge rate for the LAVA II line and mentions five capacity options from 280mAh to 680mAh. It compares the line with the LAVA 1S battery, citing 75C against 95C, but gives no weight, size or connector for this 320mAh pack.

Options and pricing

There is one option, the 320mAh size at $24, and the title shows a pack of 5PCS. The listing says the LAVA II line has five capacity options ranging from 280mAh to the newly introduced 680mAh, but it gives no figures specific to this 320mAh option. No connector, weight or dimensions are listed for it, and the only cell detail is the 1S in the name.

How it compares

The LAVA II 1S Battery 280mAh (5PCS) is the same line in the 280mAh size at $22, while this 320mAh listing is $24. The Tattu R-Line V6.0 1300mAh 6S 160C ST LiPo Battery costs $42 and is listed as 6S1P, 22.2V and 160C, so it is a different kind of pack and does not replace a 1S battery.

Shipping and processing

• Processing. The store's shipping policy says every order, including orders placed through the Shop app, ships from its warehouse in Japan and is dispatched within 1-3 business days after payment is confirmed (checked 2026-11-11).
• Shipping cost. The policy gives a flat 800 JPY inside Japan and 5,000 JPY to eligible countries for parcels up to 2 kg, and gives no rate for heavier parcels. It does not list the eligible countries; the store's country selector offers the United States, Canada, the United Kingdom, Australia and New Zealand, and the terms of service reserve the right to limit sales to any region, so the checkout is the final test. At the rate the store used for US prices when we looked (about 0.00642 USD per JPY), 5,000 JPY is about $32; the checkout shows the exact amount.
• Price against shipping. This listing costs $24, less than the flat international shipping fee above. The policy prices shipping per parcel up to 2 kg, so what an order of several small parts pays depends on how the store packs it, and the pages do not say.
• Duties and taxes. The policy says import duties, taxes and customs clearance fees are not included in the price or the shipping cost, are charged to the recipient by the carrier (it names DHL, FedEx and Japan Post) and are outside the store's control. It declares the full value of the goods on customs papers and cannot mark a parcel as a gift or declare less. A parcel held for unpaid duties is not delivered, and if the carrier sends it back the return shipping is deducted from any refund.
• Tracking. A tracking number is issued once the parcel ships. For international parcels it can take a few days to show up, and it can change when the parcel is handed from one carrier to another.
• Batteries. The shipping policy makes no exception for lithium batteries and says nothing about sending them abroad, so ask the store whether this pack can be sent to your country before you order.

Returns and warranty

• Returns. The store's refund policy gives 30 days after receiving an item to request a return. The item must be in the condition received, unworn or unused, with tags and in its original packaging, and you need the receipt or proof of purchase. Use the contact page first: if the return is accepted the store sends a return shipping label and instructions, and items sent back without a request are not accepted. The policy does not say who pays the return shipping on a change-of-mind return. Refunds go to the original payment method within 10 business days after the store has received and inspected the item (checked 2026-11-11).
• Not returnable. The refund policy lists custom products (special orders and personalized items), perishable goods, personal care goods, hazardous materials, flammable liquids and gases, sale items and gift cards. The legal notice, which is in Japanese, adds made-to-order items, digital downloads once downloaded, and goods whose value was lost through the buyer's use or modification. For an exchange the policy says to return the item and, once the return is accepted, buy the new one separately.
• Damaged or wrong items. The refund policy asks buyers to inspect an order on arrival and to contact the store at once about a defective, damaged or wrong item so that it can evaluate the issue and make it right. The legal notice says the store exchanges or refunds such an item at its own cost.
• Warranty. The shipping policy, refund policy and legal notice describe no warranty, and we found no warranty page. The terms of service say products are provided 'as is' except as the store expressly states, disclaim warranties, and are governed by Japanese law. Many of the parts this store sells are made by other brands; nothing says whether the store or the maker handles a fault that appears after the item has been in use (checked 2026-11-11).

Before you buy

369DRONE describes itself as an FPV racing drone brand from Japan. Its About page says the founder, Daichi Sakakibara, spent over a decade as a test driver at Toyota Motor Corporation and builds products with experience from racing. These are the store's own statements (checked 2026-11-11).

The store is in Japan and quotes yen. The price on this page is its United States dollar price as of 2026-11-11; the store converts at its own rate, which moves, and a visitor in another country can see a different amount or currency.

The legal notice, written in Japanese, says the products are meant for FPV drone racing and hobby use, asks buyers to follow the Aviation Act, the Radio Act and other laws, and says the store takes no responsibility for damage caused by use that breaks the law. Those are Japan's laws. We have not checked what applies where you live and we do not say whether this product can be flown or operated legally in your country.

The English refund policy takes back items that are "unworn or unused", while the Japanese legal notice says, as we read it, unused and unopened, so check the condition rule with the store before opening the package. We have not read any independent review of this product or of the store.
