It fits the H30FLEX portable test instrument used by technicians to measure TV and broadband signal quality in the field. Capacity is rated at 2600mAh (19.24Wh), matching the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eH30FLEX platform fit:\u003c\/strong\u003e\n    The H30FLEX uses a single-cell-equivalent 7.4V Li-ion pack with a specific connector and BMS communication handshake. This replacement matches that voltage rail and connector pinout so the instrument's power management circuit accepts the pack without throwing a battery fault code.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the H30FLEX's power-on sequence and active measurement load. The BMS handled the probe initialisation current spike without tripping, and the instrument's charge indicator tracked correctly across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration step:\u003c\/strong\u003e\n    After fitting this battery, run a full calibration cycle through the H30FLEX instrument menu before deploying to site. The meter maps battery state during that sequence — skipping it causes premature low-battery warnings to fire on the first real measurement session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after the H30FLEX sat unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the H30FLEX sits unused long enough, the pack voltage drops below the BMS's minimum recovery threshold — typically around 2.5V per cell. At that point the BMS enters a protective lockout state and blocks both charge and discharge. The instrument will not power on and the charger shows no activity. To recover, apply a compatible charger that supports a trickle or pre-charge mode and hold it on the pack for 15–30 minutes until cell voltage climbs above 3.0V per cell, at which point the BMS re-enables normal charging.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eH30FLEX display showing an inconsistent battery percentage at every reboot\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage-threshold recalibration issue, not a fault with the replacement pack. The H30FLEX's battery indicator is referenced against voltage thresholds tuned to the original cells — a new pack with slightly different internal resistance reads the same open-circuit voltage but behaves differently under load. The percentage shown at startup is estimated from resting voltage alone, so it can jump 10–20% once the instrument starts drawing current. Run two or three full charge-discharge cycles through normal field use and the meter's percentage will stabilise against the new pack's actual discharge profile.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360653312090,"sku":"BWCS-TVH300SL-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360653344858,"sku":"BWCS-TVH300SL-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360653377626,"sku":"BWCS-TVH300SL-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TVH300SL-1.webp?v=1778616178","url":"https:\/\/batteryweb.com\/products\/televes-h30flex-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
